Abstract [en]

Objective: The aim of the study was to investigate the noise exposure for different technical officials during a major badminton tournament.

Methods: Individual noise exposure for technical officials was measured during the 23rd BWF World Championship, 2017 in Glasgow, Scotland during all days of the tournament.

Results: Umpires and on-court-doctors had equivalent noise exposure, when working longer shifts, that exceeded the exposure limit according to the EU 2003/10/EC noise directive. Exposure limits regarding impulse sound was also exceeded during several work shifts during the tournament.

Conclusions: Technical officials are exposed to noise levels that exceed current occupational health leg-islation within the EU, and may therefore be at risk of developing hearing related disorders. It is of high importance for the organizers of sports events to reduce the noise exposure for the technical officials by scheduling shorter work periods, but also by providing individual hearing protectors.

Abstract [en]

Objective: To assess the prevalence of pain, anxiety and depression in a sample of chronic SCI patients in Northern Sweden.

Design: Descriptive, cross-sectional study.

Setting: Specialist Clinic at a University Hospital.

Participants: 78 patients with chronic spinal cord injury, at different injury and functional level.

Outcome measures: Patients registered presented pain above, at or below injury level on a Visual Analogue Scale (VAS). Patients currently on pain medication were also registered as having pain. Depression and anxiety were assessed by the Hospital Anxiety and Depression Rating Scale (HADS).

Results: Out of 78 patients, 58 (74%) indicated current presence of pain or were on continuous pain medication. Pain above injury level was present in 32% of the patients, with a mean VAS of 15.9±20.1, range 0-60mm. Pain at injury level were present in 24% of the patients, mean VAS 11.0±17.0, range 0-50mm and 58% had pain below injury level with a mean VAS 31.4±22.3, range 0-80mm.

Clinically significant psychological disorders were reported in 4 patients (5%) for both anxiety and depression.

Conclusions: Pain is very common in persons with chronic SCI, but, at least in a drug-treated population, the pain is at a mild or moderate level. Anxiety and depression were found much less common than reported in other studies. Medication effects have been considered. Even in a presumably well-medicated and well-rehabilitated population, there is still a need for further optimization of pain management, including both pharmacological and non-pharmacological methods.

Abstract [en]

RATIONALE, AIMS AND OBJECTIVES: The aims of this study is to investigate the prevalence of patients seeking care due to different musculoskeletal disorders (MSDs) at primary health care centres (PHCs), to chart different factors such as symptoms, diagnosis and actions prescribed for patients that visited the PHCs due to MSD and to make comparisons regarding differences due to gender, age and rural or urban PHC.

METHODS: Patient records (2000) for patients in working age were randomly selected equally distributed on one rural and one urban PHC. A 3-year period was reviewed retrospectively. For all patient records' background data, cause to the visit and diagnosis were registered. For visits due to MSD, type and location of symptoms and actions to resolve the patients problems were registered. Data was analysed using cross tabulation, multidimensional chi-squared.

RESULTS: The prevalence of MSD was high; almost 60% of all patients were seeking care due to MSD. Upper and lower limb problems were most common. Symptoms were most prevalent in the young and middle age groups. The patients got a variety of different diagnoses, and between 13 and 35% of the patients did not receive a MSD diagnose despite having MSD symptoms. There was a great variation in how the cases were handled.

CONCLUSIONS: The present study points out some weaknesses regarding diagnostics and management of MSD in primary care.

Abstract [en]

PURPOSE: In tendon research, using ultrasound (US), studies often refer to tendon thickness, structural abnormalities and neovascularisation. The reliability concerning these measurements and evaluations is seldom reported. The aim of this study was to assess the intra- and inter-observer reliability for quantitative measures (thickness) and qualitative evaluations (structure and neovascularisation) of symptomatic and asymptomatic Achilles and patellar tendons with US and colour Doppler using a modified Öhberg score.

METHODS: Twenty-eight consecutive patients with symptomatic and asymptomatic Achilles (n = 27) and patellar tendons (n = 26) were included. Tendon anteroposterior thickness was measured. Tendon structure and neovascularisation were evaluated using a modified Öhberg score. US-images were evaluated twice by four independent observers.

RESULTS: Mean thickness for Achilles and patellar tendons was 8.4 mm (±2.0) and 5.5 mm (±1.7), respectively. The reliability for measures of distance was high all over (ICC = 0.963-0.999). A moderate-strong correlation was found between observers concerning evaluation of neovascularisation (r = 0.767-0.992) and poor-moderate correlation concerning evaluation of structural changes (r = 0.379-0.837). Intra-observer reliability was moderate strong for evaluations of both tendon structure (k = 0.537-0.873) and neovascularisation (k = 0.639-0.864).

CONCLUSIONS: With a strict method for how to measure tendon thickness and set criteria for evaluating structural changes and amount and distribution of neovascularisation, US and colour Doppler is a reliable method for evaluating Achilles and patellar tendons. The modified, 4-graded, Öhberg score was found to be a reproducible instrument for assessment of tendon structure and neovascularisation.

Abstract [en]

Objective: To survey the incidence of clinical risk markers and its correlation with established clinical measurements for cardiovascular disease (CVD) in a heterogeneous spinal cord injured (SCI) patient population.

Design: Descriptive, cross-sectional study.

Subjects: 78 patients with SCI, at different injury and functional level.

Methods: Anthropometric data, blood pressure, a blood lipid panel, blood glucose and a questionnaire were analyzed.

Results: Eighty-one percent of all patients had dyslipidemia (DL) and a majority of the patients with abdominal measures below the recommended cut-off levels had DL. Self-reported physical activity above the cut-off level was reported by 32.1%of the patients. There were no differences in clinical measures, serum lipid values and blood glucose between physically active and not active patients. No differences were seen between men/women, tetraplegia/paraplegia and wheelchair dependent/not wheelchair dependent patients.

Conclusion: DL is common and seems to be not treated or undertreated in the studied SCI patient group with different neurological lesion and functional levels. General anthropometric clinical measures do not seem to be valid for evaluating risk for CVD in this patient group.

Abstract [en]

PURPOSE: Treatment of patellar tendinopathy/jumper's knee with ultrasound-guided sclerosing injections or ultrasound-guided arthroscopic shaving has shown good clinical short-term results. Former studies indicate that the tendon thickness and structure stays unaffected after successful treatment. The aim of this study was to evaluate the sonographic findings and clinical outcome 3-5 years after treatment of patellar tendinopathy with ultrasound-guided sclerosing injections or arthroscopic shaving.

METHODS: Fifty-seven patellar tendons (43 patients) with chronic patellar tendinopathy were evaluated, with ultrasound, colour Doppler (CD) and visual analogue scale (VAS) for pain and satisfaction with treatment, 3-5 years after treatment. Functional status was evaluated with a single question-"Back in full loading activity?" yes or no.

RESULTS: At endpoint (mean 46 months), there was a significant decrease in anteroposterior thickness of the proximal patellar tendon in patients treated with ultrasound-guided arthroscopic shaving but not after sclerosing injections. Tendon structure had improved, and CD local blood flow had diminished significantly in both groups. There were good clinical results with a significant decrease in VAS for pain after sclerosing injections (VAS 64 ± 18 → 17 ± 23) with 74 % satisfied patients and also after arthroscopic shaving (VAS 77 ± 16 → 13 ± 23) with 80 % satisfied patients. There were no significant differences in VAS between groups. A significant correlation between low local blood flow and high patient satisfaction was found.

CONCLUSIONS: Tendon thickness decreased over time after ultrasound-guided arthroscopic shaving, and tendon structure and local blood flow decreased after both treatments. There were good, and similar, clinical results with both methods. LEVEL OF EVIDENCE: III.

Abstract [en]

Chronic musculoskeletal pain exists either as localised to a single region or as widespread to multiple sites in several quadrants of the body. Prospective studies indicate that widespread pain could act as a far end of a continuum of musculoskeletal pain that started with chronic localised pain. The mechanism by which the transition from localised pain to widespread occurs is not clear, although many studies suggest it to be an altered metabolism. In this study, systemic metabolic differences between women with chronic localised neck-shoulder pain (NP), women with chronic widespread pain (CWP) and women who were healthy (CON) were assessed. Blood samples were analysed taking a metabolomics approach using gas chromatography mass spectrometry (GC-MS) and orthogonal partial least square discriminant analysis (OPLS-DA). The metabolomics analysis showed a clear systematic difference in the metabolic profiles between the subjects with NP and the CON but only a weak systematic difference between the subjects with CWP and the CON. This most likely reflects a difference in the portion of the metabolome influenced by the two pain conditions. In the NP group, the overall metabolic profile suggests that processes related to energy utilisation and lipid metabolism could be central aspects of mechanisms maintaining disorder.

Abstract [en]

Patients suffering from work-related muscle pain (WRMP) fatigue earlier during exercise than healthy controls. Inadequate oxygen consumption and/or inadequate blood supply can influence the ability of the muscles to withstand fatigue. However, it remains unknown if oxygenation and hemodynamics are associated with early fatigue in muscles of WRMP patients. In the present study we applied near-infrared spectroscopy (NIRS) on the extensor carpi radialis (ECR) and trapezius (TD) muscles of patients with WRMP (n = 18) and healthy controls (n = 17). Our objective was to determine if there were group differences in endurance times for a low-level contraction of 15% maximal voluntary contraction (MVC)--sustained for 12-13 min, and to see if these differences were associated with differences in muscle oxygenation and hemodynamics. At baseline, oxygen saturation (StO2%) was similar between groups for the ECR, but StO2% was significantly lower for TD for the WRMP patients (76%) compared to controls (85%) (P<0.01). Also, baseline ECR blood flow was similar in the two groups. For both muscles there were a larger number of patients, compared to controls, that did not maintain the 15% MVC for the allotted time. Consequently, the endurance times were significantly shorter for the WRMP patients than controls (medians, ECR: 347 s vs. 582 s; TD: 430 s vs. 723 s respectively). Responses in StO2% during the contractions were not significantly different between groups for either muscle, i.e. no apparent difference in oxygen consumption. Overall, we interpret our findings to indicate that the early fatigue for our WRMP patients was not associated with muscle oxygenation and hemodynamics.

Abstract [en]

Objective:

To examine whether self-reported physical activity of a moderate/vigorous intensity influences risk markers for cardiovascular disease in persons with paraplegia due to spinal cord injury.

Design:

Descriptive, cross-sectional study.

Subjects:

A total of 134 wheelchair-dependent individuals (103 men, 31 women) with chronic (>= 1 year) post-traumatic spinal cord injury with paraplegia.

Methods:

Cardiovascular disease markers (hypertension, blood glucose and a blood lipid panel) were analysed and related to physical activity.

Results:

One out of 5 persons reported undertaking physical activity >= 30 min/day. Persons who were physically active >= 30 min/day were significantly younger than inactive persons. Systolic and diastolic blood pressures were lower in the physically active group. When adjusting for age, the association between systolic blood pressure and physical activity disappeared. Physical activity >= 30 min/day had a tendency to positively influence body mass index and low-density lipoprotein cholesterol/high-density lipoprotein cholesterol ratio. Men had significantly higher systolic and diastolic blood pressures than women, lower high-density lipoprotein cholesterol, higher low-density lipoprotein cholesterol/high-density lipoprotein cholesterol ratio and higher triglycerides. No other significant differences between men and women were found.

Conclusion:

Self-reported physical activity >= 30 min/day in persons with spinal cord injury positively influenced diastolic blood pressure. No other reductions in cardiovascular disease risk markers were seen after controlling for age. These results indicate a positive effect of physical activity, but it cannot be concluded that recommendations about physical activity in cardiovascular disease prevention for the general population apply to wheelchair-dependent persons with spinal cord injury.

Abstract [en]

The aim of the present study was to profile shoulder passive range of motion (ROM) and isometric strength for external (ER) and internal (IR) rotation as part of a preseason screening in adolescent national badminton players. Passive external range of motion (EROM) and internal range of motion (IROM) were examined on the dominant and nondominant shoulder in 31 adolescent national badminton players (12 females and 19 males) with a standard goniometer. Muscle strength was examined with a hand-held dynamometer in ER and IR. Total range of motion (TROM=EROM+IROM) was lower on the dominant side compared with the nondominant side in both groups (P<0.001). Males were generally stronger than females in all strength measurements except for IR on the dominant side (P<0.01). In females, IR dominant side strength was greater compared with IR on the nondominant side (P<0.05). TROM was reduced on the dominant side compared with the nondominant side in young elite badminton players, irrespective of gender. No rotational strength differences existed between the dominant and nondominant side in male players, but in female players a higher IR strength on the dominant side was not balanced by a higher ER strength.
