    Patients with chronic pain: One-year follow-up of a multimodal rehabilitation programme at a pain clinic2016In: Scandinavian Journal of Pain, ISSN 1877-8860, E-ISSN 1877-8879, Vol. 10, p. 36-42Article in journal (Refereed)
    Abstract [en]

    Background and aims: Multimodal rehabilitation (MMR) programmes, including, physical training, educational and psychological interventions by an interdisciplinary team are found to be more successful for patients with disabling chronic pain compared with less comprehensive treatments. MMR programmes are based on the biopsychosocial model and the goal is usually to improve function, quality of life and facilitate and enable return to work. As pain clinics traditionally offer conventional medical pain treatment, there is limited knowledge about MMR given in this context. The aim of our study was to describe characteristics of patients with chronic pain, treated with a MMR programme at a conventional pain clinic, to evaluate patient-reported outcome measures (PROM) from start to one year after, and to study possibly associated factors for the improvement of health-related quality of life after one year.

    Methods: A prospective, observational study with a one-year follow-up was performed.

    Subjects: A total of 42 individuals (38 females, age 44.0 ± 12.3 years and 4 men age 40 ± 8.5 years) with different pain diagnoses were included. After a team assessment, the patients began a programme that lasted about three months. The MMR programme contained coordinated, individually adapted treatments administered individually or in groups, and was based on cognitive behavioural principles. Questionnaires regarding health-related quality of life (HRQoL) (EQ-5D), insomnia (ISI), mental health (HADS), pain-related disability (PDI), kinesiophobia (TSK), current pain intensity (VAS) and sense of coherence (SOC) were used at the start of the MMR and at follow-up. Demographic data were collected from the patient records.

    Results: The PROM at baseline showed substantial pain problems with low HRQoL (EQ-5D index of 0.1 ± 0.282, and EQ VAS of 32.67 ± 20.1), moderate insomnia (ISI 18.95 ± 6.7), doubtful cases of depression and anxiety (HADS-depression 9.35 ± 4.1 and HADS-anxiety 9.78 ± 3.95), presence of pain-related disability (PDI 39.48 ±12.64), kinesiophobia (TSK 40.8 ± 9.8), as well as moderate current pain (VAS 61.31 ± 20.4). The sense of coherence was weak (SOC of 51.37 ± 14). At one-year follow-up, significant (p ≤ 0.05) improvement occurred on the EQ-5D index, EQ VAS, ISI, PDI and TSK. In the logistic regression analysis, no significant associations could be identified.

    Conclusions: MMR for patients with complex pain problems can be a successful treatment alternative at conventional pain clinics.

    Implications: Since access to rehabilitation clinics in Sweden may be limited, the availability of MMR can increase by providing this type of intervention in pain clinics. Increased knowledge of MMR in different settings can also contribute to increased understanding and collaboration between pain clinics and rehabilitation units.

    Self-reported musculoskeletal complaints and injuries and exposure of physical workload in Swedish soldiers serving in Afghanistan2018In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 13, no 4, article id e0195548Article in journal (Refereed)
    Abstract [en]

    Background: Musculoskeletal complaints and injuries (MSCI) are common in military populations. However, only a limited number of studies have followed soldiers during international deployments and investigated the prevalence of MSCI during and at the end of their deployment. The aim was to describe the prevalence of MSCI in different military occupational specialties and categorise their most common tasks in terms of exposures to physical workloads during a six-month long international deployment in Afghanistan. Methods: Cross-sectional survey, including 325 soldiers (300 men), aged 20-62 participating in an international deployment in Afghanistan during the spring of 2012. Soldiers were clustered into different military occupational specialties: Infantry, Administration, Logistics, Logistics/Camp, Medical and Other. Data were collected through the use of the Musculoskeletal Screening Protocol at the end of the international mission. Results: Forty-seven percent reported MSCI during deployment, with 28% at the end. The most common locations of MSCI during the mission were lower back, knee, shoulders, upper back, neck and foot, while the knee and lower back prevailed at the end of the mission. Almost half of the soldiers who had MSCI reported affected work ability. The most common duties during the mission were vehicle patrolling, staff duties, guard/security duties, foot patrols and transportation. Soldiers reported that vehicle patrolling, staff duties and transportation were demanding with respect to endurance strength, guard/security duties challenged both maximum and endurance strength while foot patrolling challenged maximum and endurance strength, aerobic and anaerobic endurance and speed. Conclusions: MSCI during international deployment are common among Swedish soldiers. The results indicate the need to further develop strategies focusing on matching the soldiers' capacity to the job requirements, with relevant and fair physical selection-tests during the recruitment process and proactive interventions targeting MSCI before and during deployment, in order to enhance soldiers' readiness and promote operational readiness.

    From authority to coach: parents' experiences of streching as a home programme for childrern with cerebral palsy2010In: Advances in Physiotherapy, ISSN 1403-8196, E-ISSN 1651-1948, Vol. 12, no 4, p. 208-216Article in journal (Refereed)
    Abstract [en]

    Stretching is a common treatment for children with cerebral palsy, carried out by parents together with their children in the home. The aim of the present study was to explore parents’ experiences of carrying out stretching as a home programme. In order to capture the informants’ own perceptions and experiences, a qualitative method, the Grounded Theory, was chosen. Fifteen semi-structured interviews with parents, using open-ended questions, were analysed. One core category, “From authority to coach”, and two categories, “Prerequisites for parenting during stretching” and “Child and parent interaction”, emerged. The parents described a gradual development of their own role in the home stretching programme, from that of an authority, when the child was young, to that of a coach when the child grew older. With this gradual development came an increased level of participation from the child, enabling stretching to be carried out regularly. According to the parents, stretching could not be carried out without the child's active participation. Along with the process, the parents perceived increasing stress through added pressure and demands. Mobility, time, coping strategies for stress and support from professionals, in particular physiotherapists, were important prerequisites for parents to help their child best with stretching exercises.

    ”Jag vill inte vara en känslig person”: Förväntningars betydelse för ungdomars smärthantering ur ett genusperspektiv2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Introduktion: Smärta är något som drabbar alla och tar sig i uttryck på många olika sätt. Förekomsten av smärta har under senare år ökat i Sverige hos både män och kvinnor. Eftersom smärta är vanligt förekommande är det viktigt att bredda kunskapen inom området.

    Syfte: Syftet med studien var att ur ett genusperspektiv studera ungdomars upplevelse av hur de hanterar smärta samt hur erfarenheter från uppväxten har påverkat detta.

    Metod: För att få en djupare och mer nyanserad bild av hur ungdomars erfarenheter ser ut och hur de upplever, hanterar och förhåller sig till smärta så valdes en kvalitativ innehållsanalys som metod. Materialet samlades in genom semistrukturerade intervjuer.

    Resultat: Utifrån analysen av intervjuerna bildades ett tema samt sex kategorier. Det framkom att förebilders beteenden och förväntningar av genus påverkade bland annat mognadsprocessen och bildandet av trygghetszoner hos ungdomarna. Det visade sig också att förebilders beteenden, förväntningar av genus, mognadsprocesser och trygghetszoner tillsammans bidrog till att ungdomar bland annat hanterade smärta genom att bita ihop.

    Konklusion: Förväntningar utifrån normer, individen själv och personer i deras omgivning spelade en central roll i hur förhållning och hantering av smärta förändrades under uppväxten. Även erfarenhet och kunskap visade sig vara viktiga komponenter till ungdomars smärthantering.

    Betydelse av undersökningsmetod vid utvärdering av lårmuskeluthållighet hos personer med kroniskt obstruktiv lungsjukdom: En kontrollerad tvärsnittsstudie2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning: För personer med kroniskt obstruktiv lungsjukdom (KOL) är nedsatt styrka och/eller uthållighet i lårmuskulaturen en av de vanligaste extrapulmonella konsekvenserna av sjukdomen vilket även har stor betydelse för livskvalitet och framtida prognos för den enskilda individen. Rekommendationen är att muskelstyrka utvärderas med isometrisk (statisk) mätning men det finns dock ingen konsensus om hur utvärderingen ska genomföras avseende muskeluthållighet.

    Syfte: Syftet var att undersöka och jämföra om val av utvärderingsmetod är av betydelse för att upptäcka eventuella skillnader i lårmuskeluthållighet hos personer med KOL jämfört med friska ålders- och könsmatchade kontroller.

    Metod: Tvärsnittsstudie bestående av tio personer med KOL och tio ålders- och könsmatchade friska individer. Dessa genomförde tre tester av muskeluthållighet, (isokinetiskt, isometriskt och isotoniskt), i en stationär dynamometer. Jämförelse mellan testerna gjordes genom beräkning av effektstorlek (ES) som graderades enligt en standardiserad skala.

    Resultat: Jämförelse av lårmuskeluthållighet mellan personer med KOL och friska ålders- och könsmatchade kontroller visar att ES var större vid dynamiska tester (medelstor ES vid både isokinetisk ES=0.71 och isotoniska ES=o.68) jämfört med det statiska testet (isometriska ES=0.16 som är en liten ES). Detta till trots fanns ingen signifikant skillnad i lårmuskeluthållighet mellan grupperna (p>0.05).

    Slutsats: De dynamiska testernas ES indikerar på att dessa är känsligare för att mäta skillnader i lårmuskelfunktion vid KOL än det statiska testet. Den oväntade avsaknaden av statistiskt signifikant skillnad mellan grupperna i lårmuskeluthållighet skulle kunna förklaras av att kontrollgruppen inte var representativ.

    Biomechanical and neural aspects of eccentric and concentric muscle performance in stroke subjects: Implications for resistance training2012Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Muscle weakness is one of the major causes of post-stroke disability. Stroke rehabilitation programs now often incorporate the same type of resistance training that is used for healthy subjects; however, the training effects induced from these training strategies are often limited for stroke patients. An important resistance training principle is that an optimal level of stress is exerted on the neuromuscular system, both during concentric (shortening) and eccentric (lengthening) contractions. One potential problem for post-stroke patients might be difficulties achieving sufficient levels of stress on the neuromuscular system. This problem may be associated with altered muscular function after stroke. In healthy subjects, maximum strength during eccentric contractions is higher than during concentric contractions. In individuals with stroke, this difference in strength is often increased. Moreover, it has also been shown that individuals with stroke exhibit alteration with respect to how the strength varies throughout the range of motion. For example, healthy subjects exhibit a joint specific torque-angle relationship that normally is the same irrespective of contraction mode and contraction velocity. In contrast, individuals with stroke exhibit an overall change of the torque-angle relationship. This change, as described in the literature, consists of a more pronounced strength loss at short muscle length. In individuals with stroke, torque-angle relationships are only partially investigated and so far these relationships have not been analysed using testing protocols that include eccentric, isometric, and concentric modes of contraction.

     

    This thesis investigates the torque-angle relationship of elbow flexors in subjects with stroke during all three modes of contractions – isometric, concentric, and eccentric ­– and the relative loading throughout the range of movement during a resistance exercise. In addition, this thesis studies possible central nervous system mechanisms involved in the control of muscle activation during eccentric and concentric contractions.

     

    The torque-angle relationship during maximum voluntary elbow flexion was examined in stroke subjects (n=11), age-matched healthy subjects (n=11), and young subjects (n=11) during different contraction modes and velocities. In stroke subjects, maximum torque as well as the torque angle relationship was better preserved during eccentric contractions compared to concentric contractions. Furthermore, the relative loading during a resistance exercise at an intensity of 10RM (repetition maximum) was examined. Relative loading throughout the concentric phase of the resistance exercise, expressed as percentage of concentric torque, was found to be similar in all groups. However, relative loading during the eccentric contraction phase, expressed as the percentage of eccentric isokinetic torque, was significantly lower for the stroke group. In addition, when related to isometric maximum voluntary contraction, the loading for the stroke group was significantly lower than for the control groups during both the concentric and eccentric contraction phases.

    Functional magnetic resonance imaging was used to examine differences between recruited brain regions during the concentric and the eccentric phase of imagined maximum resistance exercise of the elbow flexors (motor imagery) in young healthy subjects (n=18) and in a selected sample of individuals with stroke (n=4). The motor and premotor cortex was less activated during imagined maximum eccentric contractions compared to imagined maximum concentric contraction of elbow flexors. Moreover, BA44 in the ventrolateral prefrontal cortex, a brain area that has been shown to be involved in inhibitory control of motor activity, was additionally recruited during eccentric compared to concentric conditions. This pattern was evident only on the contralesional (the intact hemisphere) in some of the stroke subjects. On the ipsilesional hemisphere, the recruitment in ventrolateral prefrontal cortex was similar for both modes of contractions. 

     

    Compared to healthy subjects, the stroke subjects exhibited altered muscular function comprising a specific reduction of torque producing capacity and deviant torque-angle relationship during concentric contractions. Therefore, the relative training load during the resistance exercise at a training intensity of 10RM was lower for subjects with stroke. Furthermore, neuroimaging data indicates that the ventrolateral prefrontal cortex may be involved in a mechanism that modulates cortical motor drive differently depending on mode of the contractions. This might partly be responsible for why it is impossible to fully activate a muscle during eccentric contractions. Moreover, among individuals with stroke, a disturbance of this system could also lie behind the lack of contraction mode-specific modulation of muscle activation that has been found in this population. The altered neuromuscular function evident after a stroke means that stroke victims may find it difficult to supply a sufficient level of stress during traditional resistance exercises to promote adaptation by the neuromuscular system. This insufficiency may partially explain why the increase in strength, in response to conventional resistance training, often has been found to be low among subjects with stroke.

    Test-retest och interbedömarreliabilitetav tre fysiska tester för militärtjänsten2013Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Reliabla testmetoder behövs för att mäta fysisk prestationsförmåga vid rekrytering och uppföljning av personer i militärtjänst. Olika fysiska testbatterier används i länder med väpnade styrkor, men bara ett fåtal av de är uvärderade för reliabilitet. Det svenska försvaret har utvecklat ett nytt testbatteri innehållande sex fysiska tester. Valet av dessa är grundat på de operativa kraven. Syftet med denna studie har varit att bedöma test-retest och interbedömarreliabiliteten av testerna, Dips, Sidoplankan och Ranger test.

    Metod: Totalt 43 friska, aktiva, tjänstgörande militärer vid Göta regemente i Eksjö, ålder 19-46, genomförde alla tester. För att bedöma test-retest testades deltagarna vid två tillfällen, separerade av sju dagar, av en bedömare. Inter-bedömarreliabilitet bedömdes vid det andra testtillfället med fyra bedömare. Test-retest och inter-bedömarreliabilitet analyserades med hjälp av intra-klass korrelationskoefficienten (ICC), standard error of measurement (SEM) och smallest real difference (SRD).

    Resultat: Föreliggande studie visade utmärkta ICC-värden (0,992 till 1,0) för inter-bedömarreliabilitet. Test-retest visade goda till utmärkta ICC-värden (0,713-0,963). SEM% värdet vid test-retest var för Dips (12.6%), för Sidoplankan (17.2%) och Ranger test (22.2%).

    Slutsats: Studien visade att Dips, Sidoplankan och Ranger test är reliabla test för att mäta soldaters fysiska prestationsförmåga. Resultaten från studien kan ge värdefull information för forskare och kliniker som vill bedöma fysisk prestation även i andra sammanhang.

    Samband mellan fysisk aktivitet och självskattad hälsa: En enkätstudie bland svenska ungdomar i årskurs 92018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Introduktion: Fysisk aktivitet (FA) rekommenderas 60 minuter dagligen på måttlig och/eller hög intensitet för barn och unga baserat på många hälsoeffekter som forskning har påvisat. Majoriteten av de svenska ungdomarna kommer inte upp i rekommendationen för FA. Samtidigt konstateras det att allt fler unga har psykosomatisk och psykisk ohälsa. Tidigare forskning visar att FA kan påverka upplevd hälsa hos en individ.

    Syfte: Att undersöka sambandet mellan självskattade fysiska aktivitet och självskattade hälsa i ett urval av ungdomar i årskurs 9

    Metod: Kvantitativ enkätstudie bestående av svenska ungdomar i årskurs 9 (n=58). FA mättes med IPAQ Short Form och självskattad hälsa mättes med frågor hämtade från SF-36 Hälsoenkät.

    Resultat: N=27 (50%) nådde upp till rekommendationerna för FA. Majoriteten, n=44 (77,2%), av ungdomarna skattade sin hälsa som God till Utmärkt. Ett svagt samband sågs mellan minuter FA i veckan av måttlig och hög intensitet och självskattad hälsa, r=0,492. Ett svagt samband sågs mellan minuter av måttlig FA och självskattad hälsa, r= 0,332, och minuter högintensiv FA och självskattad hälsa, r=,0,411. Av de 27 deltagare som inte kom upp i rekommendationerna för FA mådde n=12 (44%) dåligt. Alla deltagarna som kom upp i rekommendationerna för FA mådde n=27 (100%) bra.

    Diskussion: Majoriteten av ungdomarna som deltog i studien upplever att de mår bra samtidigt som hälften når upp till rekommendationen för FA. Urvalsgruppen var liten och homogen vilket kan ha påverkat resultatet. Resultatet motsäger större delen av tidigare forskning som visat att ett starkt samband finns mellan FA och självskattad hälsa.

    Fysioterapeutstudenters uppfattningar om psykisk ohälsa hos unga och interventioner via e-hälsa2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Introduktion: Psykisk ohälsa hos unga är ett utbrett folkhälsoproblem, samtidigt som det för hälso- och sjukvården är en utmaning att nå ut till denna grupp. Fysioterapi är verksamt vid psykisk ohälsa, men huruvida fysioterapeutiska interventioner för unga med psykisk ohälsa kan förmedlas via e-hälsa behöver utforskas vidare.

    Syfte: Syftet med studien var att utforska fysioterapeutstudenters uppfattningar om 1) psykisk ohälsa hos unga samt 2) e-hälsa som en väg att förmedla fysioterapi till unga med psykisk ohälsa.

    Metod: I denna studie tillämpades kvalitativ metod och resultatet baserades på sju semistrukturerade individuella intervjuer med fysioterapeutstudenter. Intervjuerna analyserades med vägledning av metoden socialkonstruktivistisk GT. 

    Resultat: Analysen av resultatet mynnade ut i kärnkategorin Verktyg men ingen väg för ohälsan som inte syns, samt fyra kategorier med tillhörande subkategorier. Resultatet presenterar fysioterapeutstudenters uppfattningar om hur psykisk ohälsa hos unga är mer utbrett än vad det till synes verkar. Fysioterapi uppfattas vara verksamt för att hjälpa unga med psykisk ohälsa, samtidigt som fysioterapeuten har svårt att nå unga. E-hälsa diskuteras som en potentiell väg att förmedla fysioterapeutiska interventioner vid psykisk ohälsa.

    Konklusion: Av resultatet framkom att psykisk ohälsa hos unga uppfattas vara vanligt och att fysioterapeuten har en viktig roll både i preventivt och behandlande arbete med unga. Samtidigt som det upplevs vara svårt för fysioterapeuten att nå ut till unga, kan en dualistisk syn på hälsa försvåra implementering av fysioterapeutiska interventioner för unga med psykisk ohälsa. E-hälsa kan fungera som ett komplement för att nå ut med fysioterapeutiska interventioner till unga med psykisk ohälsa.

    Muskuloskeletala besvär, upplevd hälsa och krav/kontroll hos Load Haul Dump-förare i malmgruva2013Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Introduktion:

    Syftet var att undersöka förekomst av muskuloskeletala besvär, hälsa, upplevd krav/kontroll i arbetet och upplevelse av förarmiljö hos Load Haul Dump-förare, samt undersöka skillnader mellan de som kör el- respektive dieseldriven Load Haul Dump-maskin.

     

    Metod:

    Ett kvantitativt frågeformulär rörande förekomst av muskuloskeletala besvär (Nordic Musculosceletal Questionnaire - NMQ), hälsa, krav/kontroll (Demand Control Questionnaire - DCQ) och förarmiljö besvarades av LHD-förarna. 104 (12 kvinnor, 90 män, 2 uppgav ej kön) av totalt 138 raslastare deltog i studien. Bortfallet var 25 %.

     

    Resultat:

    79 % hade upplevt muskuloskeletala besvär senaste året. Nacke, ländrygg och

    skuldra/axel var vanligaste besvärsområdena. Besvärsfrekvensen var högre hos de som körde dieseldriven maskin. 79,6 % upplevde hälsan som god. Endast 27,7 % upplevde högra krav och låg kontroll i arbetet.

     

    Konklusion:

    Hög besvärsförekomsten kan ha orsakats av helkroppsvibrationer kombinerat med ogynnsamma kroppsställningar, maskinens skick samt förarstolens inställningsmöjligheter. Dieselmaskinens stol hade mindre rotation och stolinställning samt maskinskick upplevdes i högre grad som sämre, vilket kan vara en anledning till att dieselförarna uppgett mer besvär. Maskinens skick och utformning har stor betydelse varför fortsatta ergonomiska interventioner är viktiga.

    Metod:Ett kvantitativt frågeformulär rörande förekomst av muskuloskeletala besvär (Nordic Musculosceletal Questionnaire - NMQ), hälsa, krav/kontroll (Demand Control Questionnaire - DCQ) och förarmiljö besvarades av LHD-förarna. 104 (12 kvinnor, 90 män, 2 uppgav ej kön) av totalt 138 raslastare deltog i studien. Bortfallet var 25 %.Resultat:79 % hade upplevt muskuloskeletala besvär senaste året. Nacke, ländrygg och skuldra/axel var vanligaste besvärsområdena. Besvärsfrekvensen var högre hos de som körde dieseldriven maskin. 79,6 % upplevde hälsan som god. Endast 27,7 % upplevde högra krav och låg kontroll i arbetet.

    Konklusion:Hög besvärsförekomsten kan ha orsakats av helkroppsvibrationer kombinerat med ogynnsamma kroppsställningar, maskinens skick samt förarstolens inställningsmöjligheter. Dieselmaskinens stol hade mindre rotation och stolinställning samt maskinskick upplevdes i högre grad som sämre, vilket kan vara en anledning till att dieselförarna uppgett mer besvär. Maskinens skick och utformning har stor betydelse varför fortsatta ergonomiska interventioner är viktiga.

    Can Kinesiophobia, Disability and Pain Intensity Discriminate Between Different Patterns of Control Impairment in Patients With Persistent Low Back Pain?2010Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Abstract

    Introduction

    Inconsistent results regarding the efficacy of different treatment modalities for non-specific low back pain (NSLBP) indicate a need for a deeper understanding of what characterise different sub-groups of LBP patients.

    Aim

    To investigate whether kinesiophobia, disability and pain intensity can discriminate between different movement control impairment patterns in patients with NSLBP, and further, to investigate if there are any existing differences between men and women in these variables.

    Design

    Cross-sectional design.

    Method

    A total of 71 patients (33 men, 38 women, mean age of 42.2±10.1) with movement control impairment were classified into five sub-groups based on their direction of control impairment, i.e. flexion-, flexion/lateral shifting-, active extension-, passive extension- or multidirectional pattern, in the low back and analysed for in between group differences in kinesiophobia (Tampa Scale of Kinesiophobia), disability (Roland and Morris Disability Questionnaire) and pain intensity (Visual Analogue Scale). Further, a multiple discriminant analysis (MDA) was executed in order to investigate whether these variables discriminate between these patterns of impairment.

    Result

    The MDA produced no significant functions that could discriminate between different control impairment patterns and therefore no in between group differences were found. A wide distribution within the different patterns exist. Men had a significantly higher level of kinesiophobia compared to women.

    Conclusion

    Kinesiophobia, disability and pain intensity do not discriminate between movement control impairment patterns in NSLBP. Further research is needed to find whether there are other anticipatoryfactors than the direction of the patients control impairment that characterise these sub-groups. Finally, the wide distribution in kinesiophobia, disability and pain intensity within the different patterns of impairment indicate the importance of an individual focus in examining these factors in every patient.

    Can accelerometry be used to discriminate levels of activity?2009In: Ergonomics, ISSN 0014-0139, E-ISSN 1366-5847, Vol. 52, no 8, p. 1019-1025Article in journal (Refereed)
    Abstract [en]

    The aims of this study were to investigate the associations between an activity logbook and the RT3 accelerometer and to assess whether the RT3 can discriminate activity levels in healthy adults. Ten participants completed two trials wearing an RT3 accelerometer over a 4-6h period and completed a detailed activity log. Results showed a poor correlation between the RT3 in moderate activities (r=0.22) in comparison to low (r=0.52) and hard (r=0.70) from the logbook. A significant difference was found in average RT3 vector magnitude (VM) counts/min in each activity level (p0.0001). Discriminant analysis demonstrated that an RT3VM counts/min value of approximately 500 was found to have high sensitivity (88%), and specificity (88%) for discriminating between low and moderate activity levels from the logbook. This study found that accelerometry has the potential to discriminate activity levels in free living. This study is the first to investigate whether tri-axial accelerometry can discriminate different levels of free-living activity recorded in an activity logbook. The RT3 accelerometer can discriminate between low and moderate physical activities and offers a methodology that may be applicable to future research in occupational settings.

    Physical health of support worker in the aged care sector: – A cross-sectional study2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Introduktion: En växande och åldrande befolkning sätter ökade krav på äldrevården. Tillräckligt med arbetskraft och att vårdgivarna förblir friska kommer därför att vara viktigt för att möta den åldrande befolkningens behov.

     

    Syfte: Att undersöka den fysiska hälsan hos vårdgivare inom äldreomsorgen och att jämföra hälsan hos personal ifrån hemtjänsten med dem i särskilda boenden samt att se hur de förhåller sig mot en normal befolkning.

     

    Metod: Tjugoen stycken vårdgivare inom äldreomsorgen deltog frivilligt i denna studie. Varje deltagare fyllde i tre olika frågeformulär och genomgick en hälsoundersökning. Blodtryck, puls, vikt, längd och midjemått registrerades. Deltagarna fick även utföra tre fysiska tester; Grip Strength, 30 Second Chair Stands Test och Six Minute Walk Test. Medel, standardavvikelse och spridning beräknades och medelvärden analyserades deskriptivt i jämförelse mot normativa data. De i hemtjänsten jämfördes med de ifrån särskilda boenden med hjälp av Two-Sample T-test: Assuming Unequal Variances.

     

    Resultat: Alla som deltog i studien var kvinnor med en medelålder på 50.5 (SD 10.3) år, blodtryck på 125.8 (SD 14.2)/81.2 (SD 10.8) mmHG, vilopuls på 73.2 (SD 8.5) bpm, längd 162.0 (SD 8.4) cm, vikt 83.8 (SD 21.8) kg, BMI 31.8 (SD 7.6), midjemått på 93.5 (SD 14.8) cm, waist to height ratio (WtHR) 0.6 (SD 0.1). Exercise Self-Efficacy Scale (ESES) 7.3 (SD 1.15), handstyrka L/R 31.8 (SD 7.2)/34.7 (SD 7.4) kg, chair stands test 13.4 (SD 3.3) reps och sex minuters gångdistans (6MWD) 554.8 (SD 57.7) meter. BMI, midjemått, WHtR och greppstyrka visade alla högre värden än den normativa datan. 30s Sit to Stand och 6MWD visade liknande resultat som den normativa datan. Ingen signifikant skillnad visade sig mellan grupperna förutom högre värden för hemtjänstpersonal i WtHR  (p=0.04)

     

    Konklusion: Denna studie visar på att vårdgivarna som deltog var överlag hälsosamma förutom att de var feta. Resultatet var överlag liknande den normativa datan förutom BMI, midjemått och WHtR.  Ingen signifikant skillnad sågs när grupperna jämfördes förutom vid en varibel, WtHR. Lågt deltagarantal försvårar studiens resultat att gälla för en generell befolkning. Fortsatt forskning är nödvändig och bör fokusera på att rekrytera fler manliga deltagare och fler deltagare ifrån både hemtjänsten och ifrån särskilda boenden.

    Långvarig smärta och utmattningssyndrom – Olika diagnoser, liknande besvär?2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Abstract: Chronic pain and exhaustion disorder are included in the choice of care "Rehabilitation of chronic pain with or without comorbidity and exhaustion disorder". The choice of care aims to offer patients specialized multimodal rehabilitation. To be included in the choice of care, patients with chronic pain should score ≥50 on the short version of the self-assessment form Örebro Musculoskeletal Pain Screening Questionnaire (ÖMPSQ Short). To be included in the choice of care, patients with exhaustion disorder should score ≥4,0 on the self-assessment form Shirom-Melamed Burnout Measure (SMBM).

    Aims: To evaluate whether there were similarities/differences between patients with chronic pain with or without comorbidity and patients with exhaustion disorder who were referred to a specialist clinic based on the inclusion criteria stipulated in the choice of care "Rehabilitation of chronic pain with or without comorbidity and exhaustion disorder".

    Method: Evaluation of 136 patients' responses to self-assessment forms; Personal characteristics, ÖMPSQ Short and SMBM.

    Results: Patients with exhaustion disorder could be included in the choice of care for rehabilitation of pain in 51.5% of cases, based on their responses to ÖMPSQ Short. Patients with chronic pain could be included in the choice of care for rehabilitation of exhaustion disorder in 85.7% of cases, based on their responses to SMBM. Patients with exhaustion disorder had higher education than patients with chronic pain. Patients with chronic pain were overweight or were obese and had pain in a greater proportion of the cases and a higher pain intensity compared to patients with exhaustion disorder.

    Conclusion: Most importantly to note is that patients with chronic pain also exhibit exhaustion symptoms and that patients with exhaustion disorder in the majority of cases also have pain.

    Longitudinal study exploring factors associated with neck/shoulder pain at 52 years of age2016In: Journal of Pain Research, ISSN 1178-7090, E-ISSN 1178-7090, Vol. 9, p. 303-310Article in journal (Refereed)
    Abstract [en]

    OBJECTIVES: To investigate the ability of work-related measurements, body composition, physical activity, and fitness levels to predict neck/shoulder pain (upper body pain, UBP) at the age of 52 years. Another aim was to investigate the cross-sectional relationships between UBP, work-related factors, and individual factors at the age of 52 years.

    METHODS: We followed a randomly selected cohort of 429 adolescents that was recruited in 1974 (baseline), when they were 16 years old. The participants completed physical fitness tests, questions about sociodemographic and lifestyle factors at 16, 34, and 52 years of age, and questions about work-related factors and pain in the follow-ups. Logistic regression analyses were used to examine the associations between UBP and the other variables.

    RESULTS: Univariate logistic regression analyses showed that high body mass index and the work-related factors, low control, and low social support at the age of 34 years were related to UBP at the age of 52 years. For social support, there was an interaction between men and women where the relationship between low social support and the experience of pain was more evident for women. Among women, body mass index and social support remained significantly related in the multivariate analyses. For men, social support remained significantly related. Cross-sectional relationships at the age of 52 differed from the longitudinal in the sense that measures of joint flexibility and work posture were also significantly associated with UBP.

    CONCLUSION: The fact that the cross-sectional differed from the longitudinal relationships strengthens the importance of performing longitudinal studies when studying factors that might influence the initiation of pain. UBP preventative measures might need to include both lifestyle (such as dietary habits and physical activity to ensure that the individuals are not becoming overweight) and work-related factors such as social support.

    Test-retest reliability of a novel supine knee joint position sense test2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction: Proprioception, including joint position sense (JPS), is important when coordinating body movements which require an efficient and intact sensorimotor system. However, there is no gold standard test method for evaluating JPS. The supine, active and non-weight-bearing test position in this study may make it possible to detect poor JPS in newly-injured persons. Aim: To evaluate the test-retest reliability of a novel knee JPS test in a supine position.. Method: 15 healthy and active students from Umeå University (Mean±SD: age 25±3.1 years, height 178±9.1 cm and weight 74±11.2 kg) participated on two test occasions with one week in between. The participants were instructed to flex their knee from an extended position untill a stop sign was displayed and then to reproduce the angle. The stop sign was activated when participants reached either 35 or 60 degrees knee flexion, taking into considiration reaction time and system delay within the program, 40 and 65 degrees were analysed. Thus, the participants were told that the knee angles were randomly selected. The test occasions involved five repetitions for each knee angle on each leg. An eight-camera motion capture system registered the knee joint movement of reflective markers on the participant. The intraclass correlation coefficient (ICC3,1) and standard error of the measurement (SEM) were used to report the result of the test-retest reliability. Results:. Our test indicated moderate- to good test-retest reliability where the knee flexion of 40 degrees showed a higher reliability than 65 degrees. Conclusions: This test has the potential to be developed for use in clinics to evaluate JPS. Further research should analyse the velocity component, whether there was a learning effect, and the impact of different angles.

    Motivation to participate in high-intensity functional exercise among older people with dementia2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med studien var att jämföra motivation att delta i ett högintensivt funktionellt träningsprogram (HIFE) med motivation att delta i en stillasittande social kontrollaktivitet hos äldre med demens boende i särskilda boenden. 186 personer randomiserades till träning (n=93) eller kontroll (n=93). De hade en medelålder på 85 år och 76 % var kvinnor. De hade fysiska och kognitiva nedsättningar och aktivitetsbegränsningar. Interventionen pågick under 4 månader med totalt 40 tillfällen om 45 minuter vardera. Frågor om deltagarnas motivation och utmaningar för genomförandet av aktiviteterna besvarades av aktivitetsledarna och personal.

    I hela gruppen fanns signifikant korrelation mellan motivation innan och under aktivitet. Motivation innan aktivitet skiljde sig signifikant till fördel för kontrollgruppen  vid ett av fyra mättillfällen. De största hindren för att utföra aktiviteterna var för träningsgruppen “låg motivation” och “smärta” och för kontrollaktiviteten “trötthet” och “minnesnedsättning”. 

    Äldre personer med demens som bor på serviceboende och är beroende i dagliga aktiviteter är i vår studie lika motiverade att delta i funktionellt högintensivt träningsprogram jämfört med social kontrollaktivitet. Därför kan funktionell högintensiv träning rekommenderas när sociala  aktiviteter blir svåra att genomföra pga. kognitiva nedsättningar.

    Intra-abdominal pressure increases stiffness of the lumbar spine2005In: Journal of Biomechanics, ISSN 0021-9290, E-ISSN 1873-2380, Vol. 38, no 9, p. 1873-1880Article in journal (Refereed)
    Abstract [en]

    Intra-abdominal pressure (IAP) increases during many tasks and has been argued to increase stability and stiffness of the spine. Although several studies have shown a relationship between the IAP increase and spinal stability, it has been impossible to determine whether this augmentation of mechanical support for the spine is due to the increase in IAP or the abdominal muscle activity which contributes to it. The present study determined whether spinal stiffness increased when IAP increased without concurrent activity of the abdominal and back extensor muscles. A sustained increase in IAP was evoked by tetanic stimulation of the phrenic nerves either. unilaterally or bilaterally at 20 Hz (for 5 s) via percutaneous electrodes in three subjects. Spinal stiffness was measured as the force required to displace an indentor over the L4 or L2 spinous process with the subjects lying prone. Stiffness was measured as the slope of the regression line fitted to the linear region of the force-displacement curve. Tetanic stimulation of the diaphragm increased IAP by 27-61% of a maximal voluntary pressure increase and increased the stiffness of the spine by 8-31% of resting levels. The increase in spinal stiffness was positively correlated with the size of the IAP increase. IAP increased stiffness at L2 and L4 level. The results of this:study provide evidence that the stiffness of the lumbar spine is increased when IAP is elevated.

    How to adapt the pulmonary rehabilitation programme to patients with chronic respiratory disease other than COPD2013In: European Respiratory Review, ISSN 0905-9180, E-ISSN 1600-0617, Vol. 22, no 130, p. 577-586Article in journal (Refereed)
    Abstract [en]

    Dyspnoea, fatigue, reduced exercise tolerance, peripheral muscle dysfunction and mood disorders are common features of many chronic respiratory disorders. Pulmonary rehabilitation successfully treats these manifestations in chronic obstructive pulmonary disease (COPD) and emerging evidence suggests that these benefits could be extended to other chronic respiratory conditions, although adaptations to the standard programme format may be required. Whilst the benefits of exercise training are well established in asthma, pulmonary rehabilitation can also provide evidence-based interventions including breathing techniques and self-management training. In interstitial lung disease, a small number of trials show improved exercise capacity, symptoms and quality of life following pulmonary rehabilitation, which is a positive development for patients who may have few treatment options. In pulmonary arterial hypertension, exercise training is safe and effective if patients are stable on medical therapy and close supervision is provided. Pulmonary rehabilitation for bronchiectasis, including exercise training and airway clearance techniques, improves exercise capacity and quality of life. In nonsmall cell lung cancer, a comprehensive interdisciplinary approach is required to ensure the success of pulmonary rehabilitation following surgery. Pulmonary rehabilitation programmes provide important and underutilised opportunities to improve the integrated care of people with chronic respiratory disorders other than COPD.

    Fysisk aktivitet i skolan för bättre resultat i teoretiska ämnen och kognitiva test: En systematisk litteraturgranskning2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Introduktion: Majoriteten av sveriges barn uppnår mindre än de rekommenderade 60 minuterna måttlig till kraftfull fysisk aktivitet (FA) per dag. Tidigare forskning indikerar att träning och FA i skolan kan förbättra resultaten i teoretiska ämenen, och att utökad FA inte försämrar resultaten.

    Syfte: Syftet med studien är att utifrån senaste forskningen sammanställa rekommenderad organiserad FA för skolbarn under skoltid för att maximera resultat i teoretiska ämnen och kognitiv prestation. 

    Metod: Systematisk litteraturgranskning enligt rekommendationer från en handbok av Statens beredning för medicinsk utvärdering (SBU).

    Resultat: Efter sållning kvalitetsgranskades 27 artiklar varav 18 bedömdes ha medel- eller hög kvalitet, de inkluderades därmed i den narrativa sammanvägningen. Resultaten från studierna kategoriserades mellan idrottslektioner, fysiskt aktiva teoretiska lektioner och fysiskt aktiva pauser. Studierna involverar barn och ungdomar i åldrarna 6–16 år och interventionernas duration varier från ett testtillfälle under en dag till en intervention över hela grundskolan, 9 år.

    Konklusion: Spridningen av inkluderade studiers interventioner och resultat är stor och det finns ett behov av vidare, mer omfattande, forskning. Med nuvarande evidensläge rekommenderar vi Sveriges grundskolor att överväga daglig FA av högre aerob intensitet med inslag av motorisk träning under idrottslektioner på 30-55 minuter. De äldre skolungdomarna rekommenderas även ha minst 30 minuter FA paus per dag med lägst moderat intensitet.

    Träningsmotivation och mentalt välbefinnande hos elitidrottare: En jämförelse mellan individuella idrottare och lagidrottare på elitnivå2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte: Att undersöka skillnader i motivationsprofil och mentalt välbefinnande mellan individuella idrottare och lagidrottare på elitnivå. Ytterligare syften var att studera skillnader i mentalt välbefinnande mellan elitidrottare och svensk normalpopulation, samt eventuella samband mellan motivationsprofil och mentalt välbefinnande.

     

    Metod: Självskattningsformulären BREQ-3 och HADS besvarades online av 80 elitidrottare, 45 individuella idrottare och 35 lagidrottare. Svarsenkäterna analyserades med avseende på skillnader i träningsmotivation och mentalt välbefinnande mellan de två grupperna. Även skillnader i mentalt välbefinnande mellan elitidrottarna och normativ data för Sverige analyserades.

     

    Resultat: Ingen signifikant skillnad mellan grupperna gällande motivationsprofil eller mentalt välbefinnande påvisades. Analysen visade ett signifikant samband mellan motivationsprofil och mentalt välbefinnande. Elitidrottarna skattade högre ångestnivåer men lägre depressionsnivåer jämfört med normalbefolkningen.

     

    Konklusion: Varken motivationsprofil eller mentalt välbefinnande skiljer sig för individuella idrottare och lagidrottare på elitnivå. En mer självbestämmande motivationsprofil vilket bygger på en hög grad av inre motivation, är associerat med mentalt välbefinnande. Detta innebär att en inre motivation bör eftersträvas inom elitidrotten för att öka välbefinnandet. Detta resultat indikerar även att psykisk ohälsa hos elitidrottare bör studeras ytterligare.

    What is the benefit of a high intensive exercise program?: A randomized controlled trial2010In: Advances in Physiotherapy, ISSN 1403-8196, E-ISSN 1651-1948, Vol. 12, no 3, p. 115-124Article in journal (Refereed)
    Abstract [en]

    The aim of the study was to evaluate a high intensive exercise program in stroke subjects with risk of falls regarding balance, activities of daily life, falls efficacy, number of falls and lifestyle activities. The intervention program contained high intensity functional exercises (HIFE) implemented to real-life situations together with education on falls and security aspects. This was a single-center, single-blinded, randomized controlled trial. Consecutive >55-year-old patients with risk of falls were enrolled and randomized 3–6 months after first or recurrent stroke to the intervention group (IG, n=15) or to the control group (CG, n=19) who received group discussions about hidden dysfunctions after stroke. Outcomes were Berg Balance Scale (BBS) primarily, Barthel Index (BI), Falls Efficacy Scale – International (FES-I) and number of falls secondarily and Frenchay Activities Index last 3 months (FAI-3) tertially. Assessments were done at baseline, post-intervention, 3- and 6-month follow-up by two physiotherapists and one nurse blinded to group allocation. Generalized Estimating Equations with Repeated-measure statistics were used to analyze the data. There were no significant differences between the IG and the CG regarding balance (BBS). BI at 6 months and FES-I post-intervention and 3 months follow-up showed significant improvement in the IG compared with the CG (p<0.05). Number of falls and FAI-3 were without significant change. This study suggests that our program consisting of HIFE implemented in real-life situations together with educational discussions may improve performance of everyday life activities and improve falls efficacy in stroke subjects with risk of falls.

    What is the benefit of a high intensive exercise program on health-related quality of life and depression after stroke?: A randomized controlled trial2010In: Advances in Physiotherapy, ISSN 1403-8196, E-ISSN 1651-1948, Vol. 12, no 3, p. 125-133Article in journal (Refereed)
    Abstract [en]

    The aim of the study was to evaluate the impact of a high-intensive exercise program containing high-intensive functional exercises implemented to real-life situations together with group discussions on falls and security aspects in stroke subjects with risk of falls. This was a pre-specified secondary outcome for this study. For evaluation, Short Form-36 (SF-36) health-related quality of life (HRQoL) and the Geriatric Depression Scale-15 (GDS-15) were used. This was a single-center, single-blinded, randomized, controlled trial. Consecutive ≥55 years old stroke patients with risk of falls at 3–6 months after first or recurrent stroke were randomized to the intervention group (IG, n=15) or to the control group (CG, n=19) who received group discussion with focus on hidden dysfunctions but no physical fitness training. The 5-week high-intensive exercise program was related to an improvement in the CG in the SF-36 Mental Component Scale and the Mental Health subscale at 3 months follow-up compared with baseline values while no improvement was seen in the IG at this time. For the SF-36 Physical Component Scale, there was an improvement in the whole study group at 3 and 6 months follow-up compared with baseline values without any significant changes between the IG and CG. The GDS-15 was unchanged throughout the follow-up period for both groups. Based on these data, it is concluded that high-intensive functional exercises implemented in real-life situations should also include education on hidden dysfunctions after stroke instead of solely focus on falls and safety aspects to have a favorable impact on HRQoL.

    In muscle energy technique (MET), palpation is an important tool aimed at detecting asymmetry and selecting interventions. The aim of this study was to test the inter-examiner reliability of static palpation of the transverse processes of L5 (L5), sacral sulci (SS), inferior lateral angles of the sacrum (ILA), and the medial malleoli (MM) in a clinical setting. Twenty-five participants, aged 18–78 years, with low back pain and/or sacroiliac pain with or without radiating pain to the knee, were independently examined by two experienced physiotherapists. For L5, SS, ILA, the proportion of observed agreement was 40–44% and the κ coefficient 0.11 (SE=0.12) to 0.17 (SE=0.10). For MM, the observed agreement was 52% and the κ coefficient 0.28 (SE=0.15). Differences in palpation technique seem to be the most likely source of the low inter-examiner reliability in this study. For clinical practise, continued use of these tests as methods for detecting asymmetry and selecting interventions is of doubtful utility.

    Tandvårdsstudenters och tandvårdspersonals uppfattning, upplevelse och hantering av muskulär spänning2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Introduktion: Många inom tandvårdsyrken har spänningsrelaterade besvär men det råder brist på tidigare studier om hur tandvårdspersonal upplever och hanterar muskulär spänning. Syfte: Syftet med den här uppsatsen var att beskriva hur tandvårdsstudenter och tandvårdspersonal uppfattar, upplever och hanterar muskulär spänning. Metod: Studien utgick från en kvalitativ design med semistrukturerade individuellla intervjuer. Vid analysen av intervjuerna användes en kvalitativ innehållsanalys. Åtta personer som antingen arbetade som tandvårdspersonal eller studerade till det deltog i intervjuerna. Resultat: Resultatet från intervjuerna presenterade en bred bild av hur tandvårdsstudenter och personal upplevde och hanterade muskulär spänning. Innehåller i intervjuerna utmynnade i 5 kategorier: Spänning uppfattas som en rörelseinskränkning, Fysiska besvär och spänning kopplas till arbetsställningar och långa behandlingar, Höga prestationskrav leder till stress och spänningar, Medveten hållning och träning används som strategier samt Oro för vad spänningar skulle kunna leda till i framtiden. Konklusion: Muskulär spänning uppfattades som en ofrivillig muskelaktivering som kunde leda till en rörelseinskräkning och undvikande av rörelser. Spänning upplevdes bland annat som en stramhet och smärta. Den upplevda spänningen hanterades genom fysisk aktivitet, ergonomiska justeringar och strävan mot att släppa prestationskrav. Undervisning om ergonomi och tips om träning av fysioterapeut upplevdes underlätta för tandvårdsstudenter och tandvårdspersonals uppelvda spänning. Framtida forskning inom ergonomiska hjäpmedel och behandlingsmetoder för muskuloskeletala besvär är nödvändigt hos denna yrkesgrupp.

    Motivation till fysisk träning, elitidrottare jämfört med motionärer: En enkätstudie2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning:

     Introduktion:

    Fysisk aktivitet och träning är viktiga faktorer för att hålla sig hälsosam och frisk. Trots att fysisk inaktivitet kan påverka både den fysiska och psykiska hälsan negativt så är 1,5 miljarder vuxna i hela världen inaktiva. Att förstå drivkrafterna till varför man väljer att vara fysiskt aktiv eller inte är viktigt. Tidigare studier har visat att olika typer av motivation kan vara av olika betydelser för motionärer jämfört med det som driver elitidrottare till att träna.

     Syfte:

    Syftet med denna studie var att undersöka skillnader i motivationsfaktorer bland elitidrottare inom längdskidåkning och orientering jämfört med motionärer. Hypotesen var att elitidrottarna bör ha mer inre motivation och att motionärer styrs av yttre faktorer.

     Metod:

    Självskattningsformuläret BREQ-3 delades ut till elitidrottande längdskidåkare och orienterare samt motionärer på Umeå Universitet och genom sociala medier. Tjugoen stycken elitidrottare och 25 stycken motionärer svarade på enkäten. Svaren sammanställdes och analyserades med avseende på skillnader i graden av inre och yttre motivation samt icke-motivation mellan de båda grupperna.

     Resultat:

    Resultatet visade på en signifikant skillnad i motivationsfaktorer mellan elitidrottare och motionärer där motionärerna hade en högre grad av icke-motivation och elitidrottarna hade en högre grad av inre motivationsfaktorer och av de yttre motivationsfaktorerna integrerad, identifierad och introjected reglering.

     Konklusion:

    Studien visade att elitidrottare (inom längdskidåkning och orientering) tränar framförallt för att nå ett mål och värderar fördelarna med sin träning medan motionärerna inte är lika motiverade till fysisk träning.

    Grip-force responses to unanticipated object loading: load direction reveals body- and gravity-referenced intrinsic task variables1996In: Experimental Brain Research, ISSN 0014-4819, E-ISSN 1432-1106, Vol. 110, no 1, p. 142-150Article in journal (Refereed)
    Abstract [en]

    Humans preserve grasp stability by automatically regulating the grip forces when loads are applied tangentially to the grip surfaces of a manipulandum held in a precision grip. The effects of the direction of the load force in relation to the palm, trunk, and gravity were investigated in blindfolded subjects. Controlled, tangential load-forces were delivered in an unpredictable manner to the grip surface in contact with the index finger either in the distal and proximal directions (away from and toward the palm) or in the ulnar and radial directions (transverse to the palm). The hand was oriented in: (1) a standard position, with the forearm extended horizontally and anteriorly in intermediate pronosupination; (2) an inverted position, reversing the direction of radial and ulnar loads in relation to gravity; and (3) a horizontally rotated position, in which distal loads were directed toward the trunk. The amplitude of the grip-force responses (perpendicular to the grip surface) varied with the direction of load in a manner reflecting frictional anisotropies at the digit-object interface; that is, the subjects automatically scaled the grip responses to provide similar safety margins against frictional slips. For all hand positions, the time from onset of load increase to start of the grip-force increase was shorter for distal loads, which tended to pull the object out of the hand, than for proximal loads. Furthermore, this latency was shorter for loads in the direction of gravity, regardless of hand position. Thus, shorter latencies were observed when frictional forces alone opposed the load, while longer latencies occurred when gravity also opposed the load or when the more proximal parts of the digits and palm were positioned in the path of the load. These latency effects were due to different processing delays in the central nervous system and may reflect the preparation of a default response in certain critical directions. The response to loads in other directions would incur delays required to implement a new frictional scaling and a different muscle activation pattern to counteract the load forces. We conclude that load direction, referenced to gravity and to the hand's geometry, represents intrinsic task variables in the automatic processes that maintain a stable grasp on objects subjected to unpredictable load forces. In contrast, the grip-force safety margin against frictional slips did not vary systematically with respect to these task variables. Instead, the magnitude of the grip-force responses varied across load direction and hand orientation according to frictional differences providing similar safety margins supporting grasp stability.

    Nondigital afferent input in reactive control of fingertip forces during precision grip1996In: Experimental Brain Research, ISSN 0014-4819, E-ISSN 1432-1106, Vol. 110, no 1, p. 131-141Article in journal (Refereed)
    Abstract [en]

    Sensory inputs from the digits are important in initiating and scaling automatic reactive grip responses that help prevent frictional slips when grasped objects are subjected to destabilizing load forces. In the present study we analyzed the contribution to grip-force control from mechanoreceptors located proximal to the digits when subjects held a small manipulandum between the tips of the thumb and index finger. Loads of various controlled amplitudes and rates were delivered tangential to the grip surfaces at unpredictable times. Grip forces (normal to the grip surfaces) and the position of the manipulandum were recorded. In addition, movements of hand and arm segments were assessed by recording the position of markers placed at critical points. Subjects performed test series during normal digital sensibility and during local anesthesia of the index finger and thumb. To grade the size of movements of tissues proximal to the digits caused by the loadings, three different conditions of arm and hand support were used; (1) in the hand-support condition the subjects used the three ulnar fingers to grasp a vertical dowel support and the forearm was supported in a vacuum cast; (2) in the forearm-support condition only the forearm was supported; finally, (3) in the no-support condition the arm was free. With normal digital sensibility the size of the movements proximal to the digits had small effects on the grip-force control. In contrast, the grip control was markedly influenced by the extent of such movements during digital anesthesia. The poorest control was observed in the hand-support condition, allowing essentially only digital movements. The grip responses were either absent or attenuated, with greatly prolonged onset latencies. In the forearm and no-support conditions, when marked wrist movements took place, both the frequency and the strength of grip-force responses were higher, and the grip response latencies were shorter. However, the performance never approached normal. It is concluded that sensory inputs from the digits are dominant in reactive grip control. However, nondigital sensory input may be used for some grip control during impaired digital sensibility. Furthermore, the quality of the control during impaired sensibility depends on the extent of movements evoked by the load in the distal, unanesthetized parts of the arm. The origin of these useful sensory signals is discussed.

    Quantifying the independence of human finger movements: comparisons of digits, hands, and movement frequencies.2000In: Journal of Neuroscience, ISSN 0270-6474, E-ISSN 1529-2401, Vol. 20, no 22, p. 8542-50Article in journal (Refereed)
    Abstract [en]

    To determine whether other digits move when normal humans attempt to move just one digit, we asked 10 right-handed subjects to move one finger at a time while we recorded the motion of all five digits simultaneously with both a video motion analysis system and an instrumented glove. We quantified the independence of the digits to compare (1) the different digits, (2) the right versus the left hand, and (3) movements at a self-paced frequency versus externally paced movements at 3 Hz. We also quantified the degree to which motion occurred at the proximal, middle, or distal joint of each digit. Even when asked to move just one finger, normal human subjects produced motion in other digits. Movements of the thumb, index finger, and little finger typically were more highly individuated than were movements of the middle or ring fingers. Fingers of the dominant hand were not more independent than were those of the nondominant hand. Self-paced movements made at approximately 2 Hz were more highly individuated than were externally paced movements at 3 Hz. Angular motion tended to be greatest at the middle joint of each digit, with increased angular motion at the proximal and distal joints during 3 Hz movements. Simultaneous motion of noninstructed digits may result in part from passive mechanical connections between the digits, in part from the organization of multitendoned finger muscles, and in part from distributed neural control of the hand.

    "The balancing act". Licensed practical nurse experiences of falls and fall prevention: a qualitative study2012In: BMC Geriatrics, ISSN 1471-2318, E-ISSN 1471-2318, Vol. 12, p. 62-Article in journal (Refereed)
    Abstract [en]

    Background: Falls are common in old age and may have serious consequences. There are many strategies to predict and prevent falls from occurring in long-term care and hospitals. The aim of this study was to describe licensed practical nurse experiences of predicting and preventing further falls when working with patients who had experienced a fall-related fracture. Licensed practical nurses are the main caretakers that work most closely with the patients.

    Methods: A qualitative study of focus groups interviews and field observations was done. 15 licensed practical nurses from a rehabilitation ward and an acute ward in a hospital in northern Sweden were interviewed. Content was analyzed using qualitative content analysis.

    Results: The result of the licensed practical nurse thoughts and experiences about risk of falling and fall prevention work is represented in one theme, "the balancing act". The theme includes three categories: "the right to decide", "the constant watch", and "the ongoing negotiation" as well as nine subcategories. The analysis showed similarities and differences between rehabilitation and acute wards. At both wards it was a core strategy in the licensed practical nurse work to always be ready and to pay attention to patients' appearance and behavior. At the rehabilitation ward, it was an explicit working task to judge the patients' risk of falling and to be active to prevent falls. At the acute ward, the words "risk of falling" were not used and fall prevention were not discussed; instead the licensed practical nurses used for example "dizzy and pale". The results also indicated differences in components that facilitate workplace learning and knowledge transfer.

    Conclusions: Differences between the wards are most probably rooted in organizational differences. When it is expected by the leadership, licensed practical nurses can express patient risk of falling, share their observations with others, and take actions to prevent falls. The climate and the structure of the ward are essential if licensed practical nurses are to be encouraged to routinely consider risk of falling and implement risk reduction strategies.

    One-leg hop kinematics 20years following anterior cruciate ligament rupture: Data revisited using functional data analysis2015In: Clinical Biomechanics, ISSN 0268-0033, E-ISSN 1879-1271, Vol. 30, no 10, p. 1153-1161Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Despite interventions, anterior cruciate ligament ruptures can cause long-term deficits. To assist in identifying and treating deficiencies, 3D-motion analysis is used for objectivizing data. Conventional statistics are commonly employed to analyze kinematics, reducing continuous data series to discrete variables. Conversely, functional data analysis considers the entire data series.

    METHODS: Here, we employ functional data analysis to examine and compare the entire time-domain of knee-kinematic curves from one-leg hops between and within three groups. All subjects (n=95) were part of a long-term follow-up study involving anterior cruciate ligament ruptures treated ~20years ago conservatively with physiotherapy only or with reconstructive surgery and physiotherapy, and matched knee-healthy controls.

    FINDINGS: Between-group differences (injured leg, treated groups; non-dominant leg, controls) were identified during the take-off and landing phases, and in the sagittal (flexion/extension) rather than coronal (abduction/adduction) and transverse (internal/external) planes. Overall, surgical and control groups demonstrated comparable knee-kinematic curves. However, compared to controls, the physiotherapy-only group exhibited less flexion during the take-off (0-55% of the normalized phase) and landing (44-73%) phase. Between-leg differences were absent in controls and the surgically treated group, but observed during the flight (4-22%, injured leg>flexion) and the landing (57-85%, injured leg<internal rotation) phases in the physiotherapy-only group.

    INTERPRETATION: Functional data analysis identified specific functional knee-joint deviations from controls persisting 20years post anterior cruciate ligament rupture, especially when treated conservatively. This approach is suggested as a means for comprehensively analyzing complex movements, adding to previous analyses.

    Curve analyses reveal altered knee, hip, and trunk kinematics during drop-jumps long after anterior cruciate ligament rupture2018In: Knee (Oxford), ISSN 0968-0160, E-ISSN 1873-5800, Vol. 25, no 2, p. 226-239Article in journal (Refereed)
    Abstract [en]

    Background: Anterior cruciate ligament (ACL) ruptures may lead to knee dysfunctions later in life. Single-leg tasks are often evaluated, but bilateral movements may also be compromised. Our aim was to use curve analyses to examine double-leg drop–jump kinematics in ACL-reconstructed, ACL-deficient, and healthy-knee cohorts.

    Methods: Subjects with unilateral ACL ruptures treated more than two decades ago (17–28 years) conservatively with physiotherapy (ACLPT, n = 26) or in combination with reconstructive surgery (ACLR, n = 28) and healthy-knee controls (n = 25) performed 40-cm drop–jumps. Three-dimensional knee, hip, and trunk kinematics were analyzed during Rebound, Flight, and Landing phases. Curves were time-normalized and compared between groups (injured and non-injured legs of ACLPT and ACLR vs. non-dominant and dominant legs of controls) and within groups (between legs) using functional analysis of variance methods.

    Results: Compared to controls, ACL groups exhibited less knee and hip flexion on both legs during Rebound and greater knee external rotation on their injured leg at the start of Rebound and Landing. ACLR also showed less trunk flexion during Rebound. Between-leg differences were observed in ACLR only, with the injured leg more internally rotated at the hip. Overall, kinematic curves were similar between ACLR and ACLPT. However, compared to controls, deviations spanned a greater proportion of the drop–jump movement at the hip in ACLR and at the knee in ACLPT.

    Conclusions: Trunk and bilateral leg kinematics during double-leg drop–jumps are still compromised long after ACL-rupture care, independent of treatment. Curve analyses indicate the presence of distinct compensatory mechanisms in ACLPT and ACLR compared to controls.

    Body composition and performance: influence of sport and gender among adolescents2012In: Journal of Strength and Conditioning Research, ISSN 1064-8011, E-ISSN 1533-4287, Vol. 26, no 7, p. 1799-1804Article in journal (Refereed)
    Abstract [en]

    Body composition is well known to be associated with endurance performance amongst adult skiers, however the association among adolescent cross-country and alpine skiers is inadequately explored. The study sample was comprised of 145 male and female adolescent subjects (aged 15-17 years), including 48 cross-country skiers, 33 alpine skiers, and 68 control subjects. Body composition [%body fat, %lean mass, bone mineral density (g/cm2)] was measured with a dual-emission X-ray absorptiometer, and pulse and oxygen uptake were measured at three break points during incremental performance tests to determine physical fitness levels. Female cross-country and alpine skiers were found to have significantly higher %lean mass (mean difference = 7.7%, p < 0.001) and lower %body fat (mean difference = (8.1%, p < 0.001) than female control subjects. Male cross-country skiers were found to have lower %body fat (mean difference = 3.2%, p < 0.05) and higher %lean mass (mean difference = 3.3%, p < 0.01) than male alpine skiers and higher % lean mass (mean difference = 3.7%, p < 0.05) and % body fat (mean difference = 3.2%, p < 0.05) than controls. The present study found strong associations between %lean mass and the OBLA and VO2 max weight adjusted thresholds among both genders of the cross-country skiing cohort (r = 0.47-0.67, p < 0.05) and the female alpine skiing cohort (r = 0.77-0.79, p < 0.001 for all). The present study suggests that body composition is associated with physical performance already in adolescent athletes.

    Body function in patients with early rheumatoid arthritis: a 2-year prospective study2007In: Advances in Physiotherapy, ISSN 1403-8196, E-ISSN 1651-1948, Advances in physiotherapy, ISSN 1403-8196, Vol. 9, no 4, p. 144-150Article in journal (Refereed)
    Abstract [en]

    The aim of this prospective study was to analyse joint and muscle function and aerobic capacity over 2 years in a group of patients with early rheumatoid arthritis (RA; i.e. symptomatic for <12 months) in relation to age, pain and disease activity. Sixty-six patients with early RA were followed for 24 months. Joint and muscle function was measured using Signals of Functional Impairment (SOFI) index and aerobic capacity with sub-maximal test on ergometer bicycle. Pain was estimated on Visual Analogue Scale (VAS) and disease activity using 28-joint count Disease Activity Score (DAS 28). Joint and muscle function was impaired in almost all patients at inclusion and after 24 months. Male patients were more affected compared with females and the significant correlation with pain and DAS 28 decreased over time. Aerobic capacity was maintained and not influenced by sex, age or pain but related significantly to disease activity. The majority of the patients with early RA had impairments of the joint and muscle function over 24 months, even though disease activity decreased significantly. There is a need for regular evaluations of physical functions besides disease activity to prevent continuous development of functional losses.

    Kan riktad träning för höften förbättra knäets dynamiska stabilitet: En systematisk litteraturgranskning av studier som utvärderat knävalgisering2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Introduktion: En främre korsbandsskada (ACL-skada) kan för en idrottare innebära lång frånvaro från idrott. Att hitta rätt strategi för åtgärder utifrån skaderelaterade riskfaktorer är därför viktigt för att ta fram de bästa skadeförebyggande interventionerna.

    Syfte: Syftet med denna litteraturgranskning var att undersöka om träningsåtgärder för höften kan påverka knäets dynamiska stabilitet i potentiell skadeförebyggande riktning för ACL-skada.

    Metod: Litteratursökningen gjordes i databaserna PubMed, Cinahl, Medline och Web of Science. Studier som undersökte huruvida träningsåtgärder inriktade mot höften kunde förbättra den dynamiska stabiliteten i knäleden inkluderades i litteraturgranskningen. Studiepopulationen skulle vara unga och vuxna, män och kvinnor. Studietypen skulle vara antingen randomiserade kontrollerade studier eller kliniskt kontrollerade studier, som sedan kvalitetsgranskades enligt SBU:s mall för randomiserade studier.

    Resultat: Två studier inkluderades i litteraturgranskningen, dessa bedömdes ha ”låg” och ”medelhög” risk för bias. Studierna undersökte huruvida valgisering vid dynamiska test kunde förbättras efter en styrkeintervention fokuserad mot höften. Studiernas resultat visade inga signifikanta förändringar i knäkinematik trots signifikanta förbättringar i styrkan i höftmuskulatur.

    Slutsats: Det bristande underlaget av interventionsstudier på träningsåtgärder för höften, med fokus på knäets dynamiska stabilitet, gör det svårt att dra en säker slutsats kring området. Mer studier på området är önskvärt.

    Skademekanismer, Riskfaktorer och Prevention för Främre Korsbandsskador inom Fotboll: en Review artikel2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: The Anterior Cruciate Ligament (ACL) injury is one of the most prevalent injuries among soccer players. The injury could be devastating for athletes, which might lead to drop-out from sports and other serious injuries later on. We found a need to investigate some of the most recent articles of the matter. Purpose: To investigate recent articles regarding injury mechanisms, risk factors and prevention programs for ACL injuries in soccer players. Method: The databases of PubMed, MedLine and CINHAL were searched for relevant articles for this study. The studies were only to investigate ACL injuries in soccer players and had to be published 2005 or later. Studies which investigated more sports than soccer were excluded from our study. All studies were investigated in three steps (Headline, Abstract and Full Text). Results: The results are showing that there are ACL risk factors and injurie mechanics that are prevalent in soccer players, such as hamstring/quadriceps ratio, hip and knee extension and knee valgus. The literature has also revealed that fatigue and visual stimuli also might change the biomechanics of the hip and knee. Prevention programs for ACL injuries seems to reduce the prevalence of ACL injuries in teenagers and adults, but does not have the same effect on kids. Furthermore, prevention programs do not seem to change performance variables in soccer players. Conclusions: According to the studies included in this review, kinematics and kinetics of the knee and hip have a relationship with ACL injuries. Prevention programs seem to have an injury reducing effect on teenagers and adults, but not in children. Further research should focus on investigating mechanisms and risk factors and how they interact with each other. This would create guidelines for prevention programs in the future.

    Ett nytt hindertest för utvärdering av proprioceptiv förmåga i knäleden, en pilotstudie2017Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Syfte Studien adresserar hur ett hindertest kan utvecklas och användas för att studera den proprioceptiva förmågan i knäleden under ett funktionellt test.

    Metod 25 försökspersoner rekryterades med varierande aktivitetsgrad. Elitidrottare, kontroller samt individer med främre korsbandsskada (ACL) delades in i tre grupper. Grupperna genomförde ett hindertest utan visuell feedback av hinderhöjden. Försökspersonerna fick ställa sig på en standardiserad startposition, vila det ledande benet på hindret för att skapa en efferenskopia. De försökte kliva över hindret med så liten marginal som möjligt utan att slå i hindret. Hindret flyttades utan individens vetskap. Försöken filmades i ett 3D-laboratorium. Två hinderhöjder användes, totalt gjordes 16 försök (åtta försök/ben och hinderhöjd). Avstånd i hinder till fot, knä- och höftflexionsvinkel samt hits studerades. Absoluta felet samt variationskoefficienten analyserades med oberoende t-test samt Mann Whitney u-test. Hits analyserades med Pearsons Chi2-test, signifikansnivån var p<0.05 i alla test.

    Resultat Testet var genomförbart för både knäfriska samt individer med främre korsbandsskador. Kontrollgruppen uppvisade lägre avstånd i hinder till fot för både det låga och höga hindret, för det sistnämnda var skillnaden signifikant (p=0.00). Atletgruppen uppvisade procentuellt mindre spridning i avstånd hinder till fot för både det låga och höga hindret, skillnaderna var icke signifikanta. En signifikant skillnad fanns mellan grupperna gällande antal hits, ACL-gruppen hade slagit i hindret flest gånger om detta inte flyttats under utförandet (p=0.021).

    Slutsats Att utveckla ett validerat och reliabelt mätinstrument av stor vikt för att under och efter rehabiliteringsfasen kunna utvärdera den proprioceptiva förmågan hos individer med en främre korsbandsskada.

    Användning av höj- och sänkbara bord: - En jämförelse mellan de som upplever och de som inte upplever smärta2017Independent thesis Basic level (degree of Bachelor of Fine Arts), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Kontorsarbetare spenderar lång tid stillasittande. Negativa hälsoeffekter förknippas med en stillasittande livsstil, däribland muskuloskeletal smärta. Lösningen verkar inte vara stillastående då även detta kan leda till muskuloskeletal smärta. Det finns HSB (höj- och sänkbara bord) för att minska stillasittande/stillastående hos kontorsarbetare. Mer forskning krävs gällande hur HSB används i praktiken.

    Syfte: Undersöka om det finns skillnad i användning av HSB mellan de som upplever jämfört med de som inte upplever rygg-och nacksmärta.

    Undersöka om det finns samband mellan självskattad tid stående respektive sittande och tid uppmätt med aktivitetsmätare.

    Metod: Data samlades in via självskattningenkäter som delades ut till 26 kontorsarbetare. Enkätena bestod av frågor gällande användning av HSB samt upplevd muskuloskeletal smärta. Kontorsarbetarna delades in i två grupper, smärtgruppen (SG) och icke- smärtgruppen (ISG), som jämfördes med varandra. Elva kontorsarbetare tilldelades aktivitetsmätare samt en självskattningsenkät gällande hur mycket de suttit och stått dagarna de bar aktivitetsmätaren. Sambandsanalyser mellan självskattad tid och tid uppmätt med aktivitetsmätare utfördes. 

    Resultat: Smärtgruppen varierade mer frekvent, satt mindre och stod mer men skillnaderna mot ISG var inte signifikanta (p=0,276; p=0,054; p=0,108). Svagt positiva samband (rho=0,46; rho=0,58) fanns mellan självskattad tid sittande respektive stående och tid uppmätt med aktivitetsmätare, dock var resultaten inte signifikanta (p=0,08; p=0,178).

    Konklusion: Denna studie visade inga signifikanta skillnader gällande användning av HSB mellan SG och ISG. Att SG varierade sig mer frekvent samt stod mer och satt mindre skulle dock kunna tyda på att smärta påverkar användandet av HSB. Mer forskning, fördelaktligen med aktivitetsmätare, krävs angående hur HBS används på kontorsarbetsplatser.

    Skadeförekomst bland ungdomar på elitnivå inom snowboard och freestyle2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte: Undersöka skadeförekomsten bland ungdomar på snowboard- och freestylegymnasier i Sverige samt att jämföra skadeförekomsten mellan dessa två discipliner. Metod: Retrospektiv studie baserad på frågeformulär om träningsvanor och skador under läsåret 2011/2012. Totalt 51 av 93 tillfrågade elever (freestyle n=26, snowboard n= 25, bortfall n=42) i årskurs 2-4 från snowboard- och freestylegymnasier ingick i studien. Resultat: Sammanlagt hade 27 av 51 elever (53%) skadat sig. Snowboardåkarna stod för 12 skador (34%) och freestyleåkarna för 23 skador (66%). Måttliga skador, vilket innebär 8-28 dagars frånvaro, förekom mest frekvent bland freestyleåkarna (n=11; 48%). Lätta skador (1- 3 dagars frånvaro, n=4; 33%) och allvarliga skador (>28 dagars frånvaro, n=4; 33%) var vanligast bland snowboardåkarna. Vanligaste kroppsdel att skada bland freestyleåkarna var huvudet (n=6; 26%) följt av skador i fot/häl/tå (n=5; 22%) medan skulderskador (n=4; 33%) var vanligast hos snowboardåkarna. Slutsats: Skadeförekomsten bland ungdomar på snowboard- och freestylegymnasier i Sverige är hög, mer än hälften av eleverna skadade sig minst en gång under läsåret 2011/2012. Bland freestyleåkarna var huvudskador vanligast medan skulderskador var vanligast för snowboardåkarna. Antalet knäskador var lågt bland både snowboard- och freestyleåkare. Ingen signifikant skillnad sågs i antal skadade elever mellan disciplinerna. Resultaten hade varit mer representativa för hela målgruppen om svarsfrekvensen varit högre.
