Objective: What are the core capabilities physiotherapists need to deliver quality care when working with people with dementia and their families/caregivers?

Design: A three-round modified e-Delphi study. Participants: Panel members were physiotherapists experienced in working with people with dementia and/or educating and/or researching in the dementia field.

Methods: A steering group (16 international physiotherapists and a consumer) developed a draft framework including 129 core capabilities across 5 domains for panel members to rate their appropriateness for inclusion as a core capability to provide high quality care to people with dementia and their caregivers/families. The RAND/UCLA method was used to assess consensus.

Results: Thirty-five physiotherapists from 11 countries participated in Round 1, 31 (89%) in Round 2 and 28 (80% of Round 1) in Round 3. All core capabilities were rated appropriate for inclusion in each round. Panel members recommended wording refinements across the rounds and suggested 51 core capabilities for consideration. Three rounds were needed to reach consensus, resulting in 137 core capabilities rated appropriate for inclusion across 5 domains: 1) Knowledge and understanding, n = 36; 2) Assessment, n = 39; 3) Management, interventions and prevention n = 40; 4) Communication, therapeutic relationship and person-centred care, n = 17; and 5) Physiotherapists self-management and improvement, n = 5. Conclusions: This e-Delphi study outlines the core capabilities physiotherapists need to provide high quality care to people with dementia and their families/caregivers. These core capabilities can be used by physiotherapists to help identify knowledge/skill gaps, as well as by educators to improve their training of undergraduate and postgraduate students, and clinicians.

Contribution of Paper:

• This e-Delphi study has developed, through expert consensus, the first comprehensive physiotherapy specific core capability framework for providing high-quality care to people with dementia and their families/caregivers.

• The core capability framework can be used by physiotherapists to identify knowledge and/or skill gaps, and by physiotherapy educators to assist with entry-level and post-graduate curriculum development and student/workforce training.

• As physiotherapists play a vital role in working with people with dementia and their caregivers/families, and competencies lie at the heart of effective quality care and service delivery, the newly developed core capability framework serves as basis for broader consultation and input.

Background: A team-based, individualised rehabilitation approach may be required to meet the complex needs of people with dementia. This randomised controlled pilot trial evaluated the feasibility of a person-centred multidimensional interdisciplinary rehabilitation programme for community-dwelling older people with dementia and their informal primary caregivers.

Methods: Participants with dementia were randomised to an intervention group (n = 31, mean age (SD) 78.4 (6.0) years) or usual care (n = 30, mean age 79.0 (7.1)). The rehabilitation programme consisted of a 20-week rehabilitation period containing assessments and interventions based on each individual’s goals, and group-based physical exercise plus social interaction twice a week for 16 weeks at a rehabilitation unit. After 5 and 14 months, the interdisciplinary team followed up participants over two four-week periods. For both groups, dates of deaths and decision to move to nursing home over three years, as well as interventions for the relevant periods, were collected. Blinded assessors measured physical functions, physical activity, activities of daily living, cognitive functions, nutritional status, and neuropsychiatric symptoms at baseline and at 5, 12, 24, and 36 months.

Results: Participants in the intervention group received a mean of 70.7 (20.1) interventions during the 20-week rehabilitation period, delivered by all ten team professions. The corresponding figures for the control group were 5.8 (5.9). In the intervention group, all but one participated in rehabilitation planning, including goal setting, and attendance in the exercise and social interaction groups was 74.8%. None of the adverse events (n = 19) led to any manifest injury or disease. Cox proportional hazard regression showed a non-significant lower relative risk (HR = 0.620, 95% CI 0.27–1.44) in favour of the intervention for moving to nursing home or mortality during the 36-month follow-up period. Linear mixed-effect models showed non-significant but potentially clinically meaningful between-group differences in gait, physical activity, and neuropsychological symptoms in favour of the intervention.

Conclusions: The rehabilitation programme seems feasible among community-dwelling older people with dementia. The overall results merit proceeding to a future definitive randomised controlled trial, exploring effects and cost-effectiveness. One could consider to conduct the programme earlier in the course of dementia, adding cognitive training and a control attention activity.

Trial registration: The study protocol, ISRCTN59155421, was registered online 4/11/2015.

Objectives: To investigate the association between gait speed and depressive disorders among very old adults (≥85 years).

Method: This study utilized the GERDA-database, which encompasses a representative sample of those aged 85, 90, and 95+ years residing in northern Sweden and western Finland. From four data collections between 2000 and 2017, this study included 1794 participants. Self-paced gait speed was measured over 2.4-m and depressive disorders was evaluated by a specialist in geriatric medicine according to the DSM-IV-TR criteria. T-tests and multivariable logistic regressions were used to explore differences and associations between gait speed and depressive disorders.

Results: Gait speed was independently associated with depressive disorders among very old adults (p <.001). The results showed significantly different mean gait speeds (m/s) between individuals with/without a depressive disorder (0.34 ± 0.24/0.52 ± 0.26, p <.001), between individuals with a depressive disorder with/without antidepressant treatment (0.35 ± 0.24/0.44 ± 0.24, p <.001) and between non-responders/responders to antidepressants (0.36 ± 0.21/0.42 ± 0.22, p =.020).

Conclusion: This is the first study focusing on very old adults that has shown an independent association between gait speed and depressive disorders. Responders to antidepressant medication had a higher mean gait speed than non-responders, which may imply shifts in function upon successful treatment.

BACKGROUND: Despite well-known positive effects of pulmonary rehabilitation, access is limited. New strategies to improve access are advocated, including the use of eHealth tools.

OBJECTIVES: The aim of this study was to explore prospective users' preferences for an eHealth tool to support the self-management of physical activity and exercise training in COPD.

METHODS: A qualitative research design was applied. Data was collected in six, audio recorded, digital co-creation workshops, which were guided by a participatory and appreciative action and reflection approach. A total of 17 prospective users took part in the process, including people with COPD (n = 10), relatives (n = 2), health care givers (n = 4) and a patient organization representative (n = 1). During the workshops, pre-selected relevant topics to exploring end-users' preferences for eHealth support in self-management in COPD were discussed. The workshops were recorded and transcribed. Data was analysed using inductive qualitative content analysis.

RESULTS: The overarching theme "fusing with, rather than replacing existing support structures" was uncovered when the two-sided relationship between positive expectations towards digital solutions and the fear of losing access to established rehabilitation systems, emerged in the discussions. Three categories were identified, focused on wishes for an evidence-based support platform of information about COPD, a well-designed eHealth tool including functionalities to motivate in the self-management of physical activity and exercise training, and requirements of various forms of support. Co-creators believed that there were clear benefits in combining the best of digital and existing support systems.

CONCLUSIONS: Co-creators viewed an eHealth tool including support for physical activity and exercise training as a valuable digital complement to the now existing rehabilitation services. A future eHealth tool needs to focus on user-friendliness and prospective users's requests.

Background: Adults with dementia have a high risk of falls and fall-related injuries. A greater slowing of backward walking speed (BWS) relative to forward (FWS) has been indicated with older age, and slower BWS has been related to an increased risk of falls. Similarly, slow BWS relative to FWS has been observed in people with dementia.

Research question: Is slower BWS, and slower BWS relative to FWS associated with increased risk of prospective falls in older adults with dementia?

Methods: In total, 52 women and 12 men with dementia living in nursing homes, mean age 86 years, and mean Mini-Mental State Examination score of 14.2 points were included. BWS and FWS was measured over 2.4 m, and the directional difference (DD) calculated (100*((FWS-BWS)/FWS)). Falls were followed for 6 months by review of fall incident reports in electronic medical records at nursing homes and the regional healthcare provider.

Results: Altogether, 95 falls occurred with mean incidence rate 3.1 falls per person-years. Of included participants, 15 (23%) fell once, and 17 (27%) fell twice or more. In negative binomial regression analyses, greater DD was associated with lower prospective incidence fall rate ratio, IRR (IRR= 0.96, p < .001), while BWS was not (IRR= 0.04, p = .126).

Significance: In this study of adults with dementia, slower BWS was not associated with prospective falls. However, slower BWS relative to forward (greater DD) was associated with fewer falls, and possibly a protective response. This is novel research, yet results are promising and indicate that assessing walking speed in multiple directions may inform fall risk in adults with dementia.

Background: Physical activity and sedentary behavior vary across the life span, and in very old people activity behavior can vary considerably over 24 h. A physical activity questionnaire adapted for this age group is lacking. This study was conducted to validate such a newly developed questionnaire suitable for use in very old people.

Research question: Is the International Physical Activity Questionnaire adapted for adults aged ≥ 80 years (IPAQ-E 80 +) a valid measure of physical activity in very old people?

Methods: Seventy-six participants (55.3% women) with a mean age of 84.4 ± 3.8 years wore accelerometers for ≥ 5 consecutive days, and completed the IPAQ-E 80 +. Spearman's rho and Bland-Altman plots were used to analyze the validity of IPAQ-E 80 + against accelerometer measures. Analyses were conducted for the separate items sitting, laying down at daytime and nighttime, walking, moderate to vigorous (MV) walking, and moderate to vigorous physical activity (MVPA), and the summary measures: total inactive time, sedentary time (i.e. lying down at daytime + sitting), total active time, and total MVPA + MV walking.

Results: The IPAQ-E 80 + correlated with the accelerometer measures of total inactive- (r = 0.55, p < 0.001), sedentary- (r = 0.28, p = 0.015), walking- (r = 0.54 p < 0.001) and total active- (r = 0.60, p < 0.001) times, but not with measures of intensity of walking or physical activity; MV walking (r = 0.06, p = 0.58), MVPA (r = 0.17, p = 0.13).

Significance: In this study the IPAQ-E 80 + showed fair to substantial correlations with accelerometers, and it therefore seems able to rank very old people according to levels of PA (total inactive-, sedentary-, and total active time, and walking time). The IPAQ-E 80 + seems promising for use in studies investigating associations between activity behavior and health in this population. Further investigation is needed to determine whether the IPAQ-E 80 + can accurately measure PA intensity.

Background: Using participatory methods to engage end-users in the development and design of eHealth is important to understand and incorporate their needs and context. Within participatory research, recent social distancing practice has forced a transition to digital communication platforms, a setting that warrants deeper understanding. The aim of this study was to describe the experiences of, and evaluate a digital co-creation process for developing an eHealth tool for people with chronic obstructive pulmonary disease (COPD).

Methods: The co-creation was guided by Participatory appreciative action and reflection, where a convenience sample (n = 17), including persons with COPD, health care professionals, relatives and a patient organization representative participated in six digital workshops. User instructions, technical equipment, and skilled support were provided if necessary. Workshops centred around different topics, with pre-recorded films, digital lectures and home assignments to up-skill participants. Process validity, experiences and ownership in the co-creation process were evaluated by repeated respondent validation, member checking, questionnaires and by assessing attendance. Data was analysed quantitatively or qualitatively as appropriate.

Results: The co-creators were in general satisfied with the digital format of the workshops. Mean attendance and perceived engagement in workshops was high and the experience described as enjoyable. Engagement was facilitated by up-skilling activities and discussions in small groups. Few had used digital communication previously, and feelings ranging from excitement to concern were expressed initially. Technical issues, mainly audio related, were resolved with support. At completion, skills using equipment and digital platform surpassed expectations. Few disadvantages with the digital format were identified, and advantages included reduced travel, time efficiency and reduced infection risk.

Conclusions: Experiences of digital co-creation were overwhelmingly positive, despite initial barriers related to computer naivety and use of digital equipment and platforms. The high level of satisfaction, engagement, attendance rates, and agreement between individual and group views suggests that a digital co-creation process is a feasible method. Several important success factors were identified, such as the provision of information and education on discussion topics in advance of workshops, as well as the smaller group discussions during workshops. The knowledge gained herein will be useful for future digital co-creation processes.

Introduction: Low physical activity (PA) is a potential risk factor for dementia and cognitive impairment. However, few studies have focused on very old people (aged ≥80 years), the age group with highest prevalence of dementia. The aim was to investigate if PA associated with subsequent dementia, cognitive function, and gait speed (GS), in very old people.

Methods: A population-based survey was conducted in 1999 and followed-up between 2016 and 2019 in participants ≥80 years. Altogether 541 individuals (56.2% women), 64.9 ± 4.2 years of age at baseline participated. Self-rated baseline PA was categorized into low, medium, or high. Cognitive function was assessed with the Mini-Mental State Examination (MMSE), executive function with the Frontal Assessment Battery (FAB), and GS (in meters/second) was measured over 2.4 m at follow-up.

Results: During a mean of 19.0 ± 1.1 years, 175 (32.3%) developed dementia. Low or medium PA compared to high PA did not associate with subsequent dementia, and PA did not associate with future cognitive function (MMSE). PA associated with executive function (FAB) (unstandardized beta [95% confidence interval]) (0.67 [0.07–1.27]), but not after adjustments. PA associated with subsequent GS in the unadjusted model and after adjustment for age, sex, smoking, and education (0.06 [0.02–0.09], and 0.04 [0.01–0.08], respectively), but not after adding adjustment for hypertension, obesity, and glucose intolerance.

Conclusion: No support was found for the hypothesis that low PA is a potential risk factor for dementia in very high age. However, PA and executive function were associated in unadjusted analyses which indicate that PA may be important for at least one aspect of cognitive function. The association between PA and GS around 2 decades later seems attenuated by cardiometabolic risk factors. Future investigations regarding PA, dementia, and cognitive decline may consider cardiometabolic risk factors such as hypertension, obesity, and glucose intolerance, and include repeated measures of PA over the life course.

Background: In older people with cognitive impairment (CI), executive function (EF) has been associated with motor performance including balance and gait. The literature examining and supporting a relationship between balance performance and other cognitive domains is limited.

Objective: To investigate the relationship between global cognition and cognitive domain function and balance performance in older people with CI.

Methods: The iFOCIS randomized controlled trial recruited 309 community-dwelling older people with CI. Baseline assessments completed before randomization were used for analyses including the Addenbrooke's Cognitive Examination-III (ACE-III; global cognition) and its individual cognitive domains (attention; memory; verbal fluency; language; visuospatial ability) and the Frontal Assessment Battery (FAB), a measure of EF. A composite balance score was derived from postural sway and leaning balance tests.

Results: In linear regression analyses adjusted for covariates, global cognition and each cognitive domain were significantly associated with balance performance. EF (verbal fluency; β=-0.254, p<0.001, adjusted R2=0.387) and visuospatial ability (β=-0.258, p<0.001, adjusted R2=0.391) had the strongest associations with balance performance. In a comprehensively adjusted multivariable model including all of the ACE-III cognitive domains, visuospatial ability and EF (verbal fluency) were independently and significantly associated with balance performance.

Conclusion: Poorer global cognition and cognitive domain function were associated with poorer balance performance in this sample of people with CI. Visuospatial ability and EF were independently associated with balance, highlighting potential shared neural networks and the role higher-level cognitive processes and spatial perception/processing play in postural control.

Background: Multidirectional walking, including backward walking, is integral to daily activities, and seems particularly challenging in older age, and in people with pathology affecting postural control such as dementia.

Research Question: Does exercise influence backward walking speed in people with dementia, when tested using habitual walking aids and without, and do effects differ according to walking aid use?

Methods: This study included 141 women and 45 men (mean age 85 years) with dementia from the Umeå Dementia and Exercise (UMDEX), a cluster-randomized controlled trial study set in 16 nursing homes in Umeå, Sweden. Participants were randomized to a High-Intensity Functional Exercise (HIFE) program targeting lower limb strength-, balance and mobility exercise or to a seated attention control activity. Blinded assessors measured 2.4-meter usual backward walking speed, at baseline, 4 - (intervention completion) and 7-month follow-up; tested 1) with habitual walking aids allowed, and 2) without walking aids.

Results: Linear mixed models showed no between-group effect in either backward walking speed test at 4 or 7 months; test 1) 0.005 m/s, P = .788 and –0.006 m/s, P = .754 and test 2) 0.030 m/s, P = .231 and 0.015 m/s, P = .569, respectively. In interaction analyses, exercise effects differed significantly between participants who habitually walked unaided compared with those that used a walking aid at 7 months (0.094 m/s, P = .027).

Significance: In this study of older people with dementia living in nursing homes, the effects of exercise had no overall effects on backwards walking speed. Nevertheless, some benefit was indicated in participants who habitually walked unaided, which is promising and merits further investigation in future studies.
