RESUMEN
BACKGROUND: StandingTall uses eHealth to deliver evidence-based balance and functional strength exercises. Clinical trials have demonstrated improved balance, reduced falls and fall-related injuries and high adherence. This study aimed to evaluate the implementation of StandingTall into health services in Australia and the UK. METHODS: Two hundred and forty-six participants (Australia, n = 184; UK, n = 62) were recruited and encouraged to use StandingTall for 2 h/week for 6-months. A mixed-methods process evaluation assessed uptake and acceptability of StandingTall. Adherence, measured as % of prescribed dose completed, was the primary outcome. RESULTS: The study, conducted October 2019 to September 2021 in Australia and November 2020 to April 2022 in the UK, was affected by COVID-19. Participants' mean age was 73 ± 7 years, and 196 (81%) were female. Of 129 implementation partners (e.g. private practice clinicians, community exercise providers, community service agencies) approached, 34% (n = 44) agreed to be implementation partners. Of 41 implementation partners who referred participants, 15 (37%) referred ≥5. Participant uptake was 42% (198/469) with mean adherence over 6 months being 41 ± 39% of the prescribed dose (i.e. 39 ± 41 min/week) of exercise. At 6 months, 120 (76%) participants indicated they liked using StandingTall, 89 (56%) reported their balance improved (moderately to a great deal better) and 125 (80%) rated StandingTall as good to excellent. For ongoing sustainability, health service managers highlighted the need for additional resources. CONCLUSIONS: StandingTall faced challenges in uptake, adoption and sustainability due to COVID-19 and a lack of ongoing funding. Adherence levels were lower than the effectiveness trial, but were higher than other exercise studies. Acceptance was high, indicating promise for future implementation, provided sufficient resources and support are made available.

OBJECTIVES: To evaluate the effect of a coaching intervention compared with control on physical activity and falls rate at 12 months in community-dwelling people aged 60+ years. DESIGN: Cluster randomised controlled trial. SETTING: Community-dwelling older people. PARTICIPANTS: 72 clusters (605 participants): 37 clusters (290 participants) randomised to the intervention and 35 (315 participants) to control. INTERVENTION: Intervention group received written information, fall risk assessment and prevention advice by a physiotherapist, activity tracker and telephone-based coaching from a physiotherapist focused on safe physical activity. Control group received written information and telephone-based dietary coaching. Both groups received up to 19 sessions of telephone coaching over 12 months. OUTCOMES: The co-primary outcomes were device-measured physical activity expressed in counts per minute at 12 months and falls rate over 12 months. Secondary outcomes included the proportion of fallers, device-measured daily steps and moderate-to-vigorous physical activity (MVPA), self-reported hours per week of physical activity, body mass index, eating habits, goal attainment, mobility-related confidence, quality of life, fear of falling, risk-taking behaviour, mood, well-being and disability. RESULTS: The mean age of participants was 74 (SD 8) years, and 70% (n=425) were women. There was no significant effect of the intervention on device-measured physical activity counts per minute (mean difference 5 counts/min/day, 95% CI -21 to 31), or falls at 12 months (0.71 falls/person/year in intervention group and 0.87 falls/person/year in control group; incidence rate ratio 0.86, 95% CI 0.65 to 1.14). The intervention had a positive significant effect on device-measured daily steps and MVPA, and self-reported hours per week of walking, well-being, quality of life, and disability. No significant between-group differences were identified in other secondary outcomes. CONCLUSION: A physical activity and fall prevention programme including fall risk assessment and prevention advice, plus telephone-based health coaching, did not lead to significant differences in physical activity counts per minute or falls rate at 12 months. However, this programme improved other physical activity measures (ie, daily steps, MVPA, hours per week of walking), overall well-being, quality of life and disability.

BACKGROUND: There is currently little evidence of planning for real-world implementation of physical activity interventions. We are undertaking the ComeBACK (Coaching and Exercise for Better Walking) study, a 3-arm hybrid Type 1 randomised controlled trial evaluating a health coaching intervention and a text messaging intervention. We used an implementation planning framework, the PRACTical planning for Implementation and Scale-up (PRACTIS), to guide the process evaluation for the trial. The aim of this paper is to describe the protocol for the process evaluation of the ComeBACK trial using the framework of the PRACTIS guide. METHODS: A mixed methods process evaluation protocol was developed informed by the Medical Research Council (MRC) guidance on process evaluations for complex interventions and the PRACTIS guide. Quantitative data, including participant questionnaires, health coach and administrative logbooks, and website and text message usage data, is being collected over the trial period. Semi-structured interviews and focus groups with trial participants, health coaches and health service stakeholders will explore expectations, factors influencing the delivery of the ComeBACK interventions and potential scalability within existing health services. These data will be mapped against the steps of the PRACTIS guide, with reporting at the level of the individual, provider, organisational and community/systems. Quantitative and qualitative data will elicit potential contextual barriers and facilitators to implementation and scale-up. Quantitative data will be reported descriptively, and qualitative data analysed thematically. DISCUSSION: This process evaluation integrates an evaluation of prospective implementation and scale-up. It is envisaged this will inform barriers and enablers to future delivery, implementation and scale-up of physical activity interventions. To our knowledge, this is the first paper to describe the application of PRACTIS to guide the process evaluation of physical activity interventions.

INTRODUCTION: One in three people aged 65 years and over fall each year. The health, economic and personal impact of falls will grow substantially in the coming years due to population ageing. Developing and implementing cost-effective strategies to prevent falls and mobility problems among older people is therefore an urgent public health challenge. StandingTall is a low-cost, unsupervised, home-based balance exercise programme delivered through a computer or tablet. StandingTall has a simple user-interface that incorporates physical and behavioural elements designed to promote compliance. A large randomised controlled trial in 503 community-dwelling older people has shown that StandingTall is safe, has high adherence rates and is effective in improving balance and reducing falls. The current project targets a major need for older people and will address the final steps needed to scale this innovative technology for widespread use by older people across Australia and internationally. METHODS AND ANALYSIS: This project will endeavour to recruit 300 participants across three sites in Australia and 100 participants in the UK. The aim of the study is to evaluate the implementation of StandingTall into the community and health service settings in Australia and the UK. The nested process evaluation will use both quantitative and qualitative methods to explore uptake and acceptability of the StandingTall programme and associated resources. The primary outcome is participant adherence to the StandingTall programme over 6 months. ETHICS AND DISSEMINATION: Ethical approval has been obtained from the South East Sydney Local Health District Human Research Ethics Committee (HREC reference 18/288) in Australia and the North West- Greater Manchester South Research Ethics Committee (IRAS ID: 268954) in the UK. Dissemination will be via publications, conferences, newsletter articles, social media, talks to clinicians and consumers and meetings with health departments/managers.

BACKGROUND: The evidence to support effective fall prevention strategies in older people with cognitive impairment (CI) is limited. The aim of this randomized controlled trial (RCT) was to determine the efficacy of a fall prevention intervention in older people with CI. METHOD: RCT involving 309 community-dwelling older people with CI. The intervention group (n = 153) received an individually prescribed home hazard reduction and home-based exercise program during the 12-month study period. The control group (n = 156) received usual care. The primary outcome was rate of falls. Secondary outcomes included faller/multiple faller status, physical function, and quality of life. RESULTS: Participants' average age was 82 years (95% CI 82-83) and 49% were female. There was no significant difference in the rate of falls (incidence rate ratio [IRR] 1.05; 95% confidence interval [95% CI] 0.73-1.51). A sensitivity analysis, controlling for baseline differences and capping the number of falls at 12 (4 participants), revealed a nonsignificant reduction in fall rate in the intervention group (IRR 0.78; 95% CI 0.57-1.07). Analyses of secondary outcomes indicated the intervention significantly reduced the number of multiple fallers by 26% (RR 0.74; 95% CI 0.54-0.99) when adjusting for baseline differences. There was a differential impact on falls in relation to physical function (interaction term p-value = .023) with a significant reduction in fall rate in intervention group participants with better baseline physical function (IRR 0.60; 95% CI 0.37-0.98). There were no significant between-group differences for other secondary outcomes. CONCLUSIONS: This intervention did not significantly reduce the fall rate in community-dwelling older people with CI. The intervention did reduce the fall rate in participants with better baseline physical function. CLINICAL TRIALS REGISTRATION NUMBER: Australian and New Zealand Trials Registry ACTRN12614000603617.

INTRODUCTION: Mobility limitation is common and often results from neurological and musculoskeletal health conditions, ageing and/or physical inactivity. In consultation with consumers, clinicians and policymakers, we have developed two affordable and scalable intervention packages designed to enhance physical activity for adults with self-reported mobility limitations. Both are based on behaviour change theories and involve tailored advice from physiotherapists. METHODS AND ANALYSIS: This pragmatic hybrid effectiveness-implementation type 1 randomised control trial (n=600) will be undertaken among adults with self-reported mobility limitations. It aims to estimate the effects on physical activity of: (1) an enhanced 6-month intervention package (one face-to-face physiotherapy assessment, tailored physical activity plan, physical activity phone coaching from a physiotherapist, informational/motivational resources and activity monitors) compared with a less intensive 6-month intervention package (single session of tailored phone advice from a physiotherapist, tailored physical activity plan, unidirectional text messages, informational/motivational resources); (2) the enhanced intervention package compared with no intervention (6-month waiting list control group); and (3) the less intensive intervention package compared with no intervention (waiting list control group). The primary outcome will be average steps per day, measured with the StepWatch Activity Monitor over a 1-week period, 6 months after randomisation. Secondary outcomes include other physical activity measures, measures of health and functioning, individualised mobility goal attainment, mental well-being, quality of life, rate of falls, health utilisation and intervention evaluation. The hybrid effectiveness-implementation design (type 1) will be used to enable the collection of secondary implementation outcomes at the same time as the primary effectiveness outcome. An economic analysis will estimate the cost-effectiveness and cost-utility of the interventions compared with no intervention and to each other. ETHICS AND DISSEMINATION: Ethical approval has been obtained by Sydney Local Health District, Royal Prince Alfred Zone. Dissemination will be via publications, conferences, newsletters, talks and meetings with health managers. TRIAL REGISTRATION NUMBER: ACTRN12618001983291.

BACKGROUND: Disability and falls are common following fall-related lower limb and pelvic fractures. OBJECTIVE: To evaluate the impact of an exercise self-management intervention on mobility-related disability and falls after lower limb or pelvic fracture. DESIGN: Randomized controlled trial. PARTICIPANTS: Three hundred thirty-six community dwellers aged 60+ years within 2 years of lower limb or pelvic fracture recruited from hospitals and community advertising. INTERVENTIONS: RESTORE (Recovery Exercises and STepping On afteR fracturE) intervention (individualized, physiotherapist-prescribed home program of weight-bearing balance and strength exercises, fall prevention advice) versus usual care. MAIN MEASURES: Primary outcomes were mobility-related disability and rate of falls. KEY RESULTS: Primary outcomes were available for 80% of randomized participants. There were no significant between-group differences in mobility-related disability at 12 months measured by (a) Short Physical Performance Battery (continuous version, baseline-adjusted between-group difference 0.08, 95% CI - 0.01 to 0.17, p = 0.08, n = 273); (b) Activity Measure Post Acute Care score (0.18, 95% CI - 2.89 to 3.26, p = 0.91, n = 270); (c) Late Life Disability Instrument (1.37, 95% CI - 2.56 to 5.32, p = 0.49, n = 273); or in rate of falls over the 12-month study period (incidence rate ratio 0.96, 95% CI 0.69 to 1.34, n = 336, p = 0.83). Between-group differences favoring the intervention group were evident in some secondary outcomes: balance and mobility, fall risk (Physiological Profile Assessment tool), physical activity, mood, health and community outings, but these should be interpreted with caution due to risk of chance findings from multiple analyses. CONCLUSIONS: No statistically significant intervention impacts on mobility-related disability and falls were detected, but benefits were seen for secondary measures of balance and mobility, fall risk, physical activity, mood, health, and community outings.

QUESTIONS: In people aged ≥ 60 years, does a combined physical activity and fall prevention intervention affect physical activity and mobility-related goal attainment? Does the combined intervention also improve fall rates, daily steps, the proportion of people meeting the physical activity guidelines, quality of life, mood, fear of falling, and mobility limitation? DESIGN: Randomised trial with concealed allocation, intention-to-treat analysis and assessor blinding. PARTICIPANTS: One hundred and thirty-one people living in the community and aged ≥ 60 years. INTERVENTIONS: The experimental group received one physiotherapist visit, fortnightly telephone-based health coaching, a pedometer, tailored fall prevention advice, and a fall prevention brochure. The control group received the same fall prevention brochure. OUTCOME MEASURES: Primary outcomes were mobility goal attainment (Goal Attainment Scale) and objectively measured physical activity (accelerometer counts per minute) at 6 and 12 months. Secondary outcomes were falls, other physical activity measures, quality of life, fear of falling, mood, and mobility. RESULTS: Participants had a mean age of 71 years (SD 6.5) and 31 (24%) had fallen in the past year. The experimental group reported significantly better mobility goal attainment at 6 months compared to controls (OR 2.0, 95% CI 1.1 to 3.7) but this was not maintained at 12 months (OR 1.1, 95% CI 0.6 to 2.1). Physical activity counts were not significantly different between groups at 6 months (MD 13 counts/minute, 95% CI -98 to 124) or 12 months (MD 56 counts/minute, 95% CI -14 to 125). There were no significant between-group differences in the secondary outcomes. CONCLUSION: A combined physical activity and fall prevention intervention was associated with significantly higher mobility goal attainment at 6 months. There was no significant impact on physical activity but future investigation in a larger trial is warranted. TRIAL REGISTRATION: ACTRN12614000016639.

Objectives and importance of study: Yoga improves balance and mobility, and therefore has potential as a fall prevention strategy, yet its validity for preventing falls has not been established. The Otago Exercise Programme (OEP) and tai chi are proven to prevent falls. This study aimed to evaluate the perceptions and preferences of older people towards a yoga-based program with potential to decrease falls, to compare these perceptions to the views expressed about the OEP and tai chi, and to identify participant characteristics associated with a preference for the yoga program. STUDY TYPE: Survey. METHODS: Participants were 235 community-dwellers aged 60 years or older who were not participating or had not previously participated (within the past 10 years) in yoga-based exercise. Participants completed a self-report survey measuring demographics, physical activity level and attitude. They then viewed explanations of the yoga-based program, the OEP and tai chi. Participants completed the Attitudes to Falls-Related Interventions Scale (AFRIS) to measure program acceptability and identified their preferred program. Acceptability scores and preference were compared between the programs, and factors associated with yoga preference were identified with analysis of variance. RESULTS: The mean age of participants (69% female) was 69.4 years (standard deviation 7.4). All programs were rated as equally acceptable (p = 0.17), with AFRIS scores ranging from 28.1 to 29.4. Eighty-two people (35%) preferred yoga, 32% chose the OEP and 33% chose tai chi. Overall, people who preferred yoga were significantly younger, healthier, less fearful of falling, and perceived exercise more positively than people who preferred the OEP (p values ranged from 0.03 to <0.001). The characteristics of people who preferred yoga and those who preferred tai chi did not vary significantly. CONCLUSIONS: Yoga was perceived to be appropriate and was as popular as two validated fall prevention programs. Yoga warrants further investigation as a fall prevention strategy, particularly for 'younger' and healthier people aged 60 years or older.

Background: approximately 25% of older people who fall and receive paramedic care are not subsequently transported to an emergency department (ED). These people are at high risk of future falls, unplanned healthcare use and poor health outcomes. Objective: to evaluate the impact of a fall-risk assessment and tailored fall prevention interventions among older community-dwellers not transported to ED following a fall on subsequent falls and health service use. Design, setting, participants: Randomised controlled trial involving 221 non-transported older fallers from Sydney, Australia. Intervention: the intervention targeted identified risk factors and used existing services to implement physiotherapy, occupational therapy, geriatric assessment, optometry and medication management interventions as appropriate. The control group received individualised written fall prevention advice. Measurements: primary outcome measures were rates of falls and injurious falls. Secondary outcome measures were ambulance re-attendance, ED presentation, hospitalisation and quality of life over 12 months. Analysis was by intention-to-treat and per-protocol according to self-reported adherence using negative binominal regression and multivariate analysis. Results: ITT analysis showed no significant difference between groups in subsequent falls, injurious falls and health service use. The per-protocol analyses revealed that the intervention participants who adhered to the recommended interventions had significantly lower rates of falls compared to non-adherers (IRR: 0.53 (95% CI : 0.32-0.87)). Conclusion: a multidisciplinary intervention did not prevent falls in older people who received paramedic care but were not transported to ED. However the intervention was effective in those who adhered to the recommendations. Trial registration: the trial is registered at the Australian New Zealand Clinical Trials Registry: ACTRN 12611000503921, 13/05/2011.

BACKGROUND: Physical inactivity and falls in older people are important public health problems. Health conditions that could be ameliorated with physical activity are particularly common in older people. One in three people aged 65 years and over fall at least once annually, often resulting in significant injuries and ongoing disability. These problems need to be urgently addressed as the population proportion of older people is rapidly rising. This trial aims to establish the impact of a combined physical activity and fall prevention intervention compared to an advice brochure on objectively measured physical activity participation and mobility-related goal attainment among people aged 60+. METHODS/DESIGN: A randomised controlled trial involving 130 consenting community-dwelling older people will be conducted. Participants will be individually randomised to a control group (n = 65) and receive a fall prevention brochure, or to an intervention group (n = 65) and receive the brochure plus physical activity promotion and fall prevention intervention enhanced with health coaching and a pedometer. Primary outcomes will be objectively measured physical activity and mobility-related goal attainment, measured at both six and 12 months post randomisation. Secondary outcomes will include: falls, the proportion of people meeting the physical activity guidelines, quality of life, fear of falling, mood, and mobility limitation. Barriers and enablers to physical activity participation will be measured 6 months after randomisation. General linear models will be used to assess the effect of group allocation on the continuously-scored primary and secondary outcome measures, after adjusting for baseline scores. Between-group differences in goal attainment (primary outcome) will be analysed with ordinal regression. The number of falls per person-year will be analysed using negative binomial regression models to estimate the between-group difference in fall rates after one year (secondary outcome). Modified Poisson regression models will compare groups on dichotomous outcome measures. Analyses will be pre-planned, conducted while masked to group allocation and will use an intention-to-treat approach. DISCUSSION: This trial will address a key gap in evidence regarding physical activity and fall prevention for older people and will evaluate a program that could be directly implemented within Australian health services.

OBJECTIVE: To determine whether falls can be prevented with minimally supervised exercise targeting potentially remediable fall risk factors, i.e., poor balance, reduced leg muscle strength, and freezing of gait, in people with Parkinson disease. METHODS: Two hundred thirty-one people with Parkinson disease were randomized into exercise or usual-care control groups. Exercises were practiced for 40 to 60 minutes, 3 times weekly for 6 months. Primary outcomes were fall rates and proportion of fallers during the intervention period. Secondary outcomes were physical (balance, mobility, freezing of gait, habitual physical activity), psychological (fear of falling, affect), and quality-of-life measures. RESULTS: There was no significant difference between groups in the rate of falls (incidence rate ratio [IRR] = 0.73, 95% confidence interval [CI] 0.45-1.17, p = 0.18) or proportion of fallers (p = 0.45). Preplanned subgroup analysis revealed a significant interaction for disease severity (p < 0.001). In the lower disease severity subgroup, there were fewer falls in the exercise group compared with controls (IRR = 0.31, 95% CI 0.15-0.62, p < 0.001), while in the higher disease severity subgroup, there was a trend toward more falls in the exercise group (IRR = 1.61, 95% CI 0.86-3.03, p = 0.13). Postintervention, the exercise group scored significantly (p < 0.05) better than controls on the Short Physical Performance Battery, sit-to-stand, fear of falling, affect, and quality of life, after adjusting for baseline performance. CONCLUSIONS: An exercise program targeting balance, leg strength, and freezing of gait did not reduce falls but improved physical and psychological health. Falls were reduced in people with milder disease but not in those with more severe Parkinson disease. CLASSIFICATION OF EVIDENCE: This study provides Class III evidence that for patients with Parkinson disease, a minimally supervised exercise program does not reduce fall risk. This study lacked the precision to exclude a moderate reduction or modest increase in fall risk from exercise.

BACKGROUND: Long-term benefits of exercise for people with Parkinson's disease (PD) require regular and sustained participation. This study aimed to investigate predictors of adherence to a minimally supervised exercise program designed to reduce falls in people with PD. METHOD: People with idiopathic PD who participated in the exercise arm of a randomized, controlled trial were included. Exercises were prescribed three times per week for 6 months. Adherence was defined as the percentage of prescribed sessions participants reported as having undertaken. Potential predictors of adherence included baseline measures of demographic variables, disease severity and duration, falls and fear of falling, pain, self-reported health and quality of life, cognition, physical activity levels, freezing of gait, functional mobility and balance, and knee extensor strength. RESULTS: The 108 participants included undertook a mean of 72% (standard deviation: 38%) of prescribed sessions. Participants had higher levels of adherence if they had shorter disease duration, less bodily pain, and better self-reported health and quality of life. A multivariate model (including disease duration, severity of bodily pain, self-reported physical well-being, the Frontal Assessment Battery, the Short Physical Performance Battery, and maximum walking time) explained 9% of the variance in exercise adherence, with shorter disease duration and less pain the strongest predictors (both predictors standardized ß = -0.2; P = 0.04). CONCLUSION: Disease duration and pain are likely to negatively influence exercise participation in people with PD. Given that most of the variance in adherence is unexplained, further work is required to determine other predictors of adherence to long-term exercise programs.
RESUMEN
BACKGROUND: Home exercise can prevent falls in the general older community but its impact in people recently discharged from hospital is not known. The study aimed to investigate the effects of a home-based exercise program on falls and mobility among people recently discharged from hospital. METHODS AND FINDINGS: This randomised controlled trial (ACTRN12607000563460) was conducted among 340 older people. Intervention group participants (nâ=â171) were asked to exercise at home for 15-20 minutes up to 6 times weekly for 12 months. The control group (nâ=â169) received usual care. Primary outcomes were rate of falls (assessed over 12 months using monthly calendars), performance-based mobility (Lower Extremity Summary Performance Score, range 0-3, at baseline and 12 months, assessor unaware of group allocation) and self-reported ease of mobility task performance (range 0-40, assessed with 12 monthly questionaries). Participants had an average age of 81.2 years (SD 8.0) and 70% had fallen in the past year. Complete primary outcome data were obtained for at least 92% of randomised participants. Participants in the intervention group reported more falls than the control group (177 falls versus 123 falls) during the 12-month study period and this difference was statistically significant (incidence rate ratio 1.43, 95% CI 1.07 to 1.93, pâ=â0.017). At 12-months, performance-based mobility had improved significantly more in the intervention group than in the control group (between-group difference adjusted for baseline performance 0.13, 95% CI 0.04 to 0.21, pâ=â0.004). Self-reported ease in undertaking mobility tasks over the 12-month period was not significantly different between the groups (0.49, 95% CI -0.91 to 1.90, pâ=â0.488). CONCLUSIONS: An individualised home exercise prescription significantly improved performance-based mobility but significantly increased the rate of falls in older people recently discharged from hospital.

BACKGROUND: The rate of falls in community dwelling older people with cognitive impairment (CI) is twice that of a cognitively intact population, with almost two thirds of people with CI falling annually. Studies indicate that exercise involving balance and/or a home hazard reduction program are effective in preventing falls in cognitively intact older people. However the potential benefit of these interventions in reducing falls in people with CI has not been established.This randomised controlled trial will determine whether a tailored exercise and home hazard reduction program can reduce the rate of falls in community dwelling older people with CI. We will determine whether the intervention has beneficial effects on a range of physical and psychological outcome measures as well as quality of life of participants and their carers. A health economic analysis examining the cost and potential benefits of the program will also be undertaken. METHODS AND DESIGN: Three hundred and sixty people aged 65 years or older living in the community with CI will be recruited to participate in the trial. Each will have an identifiable carer with a minimum of 3.5 hours of face to face contact each week.Participants will undergo an assessment at baseline with retests at 6 and 12 months. Participants allocated to the intervention group will participate in an exercise and home hazard reduction program tailored to their cognitive and physical abilities.The primary outcome measure will be the rate of falls which will be measured using monthly falls calendars. Secondary outcome measures will include the risk of falling, quality of life, measures of physical and cognitive function, fear of falling and planned and unplanned use of health services. Carers will be followed up to determine carer burden, coping strategies and quality of life. DISCUSSION: The study will determine the impact of this tailored intervention in reducing the rate of falls in community dwelling older people with CI as well as the cost-effectiveness and adherence to the program. The results will have direct implications for the design and implementation of interventions for this high-risk group of older people. TRIAL REGISTRATION: The protocol for this study is registered with the Australian New Zealand Clinical Trials Registry - ACTRN12614000603617.

BACKGROUND: Exercise that challenges balance can improve mobility and prevent falls in older adults. Yoga as a physical activity option for older adults is not well studied. This trial evaluated the feasibility and effect of a 12-week Iyengar yoga program on balance and mobility in older people. METHODS: We conducted a blinded, pilot randomized controlled trial with intention-to-treat analysis. Participants were 54 community dwellers (mean age 68 years, SD 7.1) not currently participating in yoga or tai chi. The intervention group (n = 27) participated in a 12-week, twice-weekly yoga program focused on standing postures and received a fall prevention education booklet. The control group (n = 27) received the education booklet only. Primary outcome was standing balance component of the short physical performance battery with addition of one-legged stance time (standing balance). Secondary outcomes were the timed sit-to-stand test, timed 4-m walk, one-legged stand with eyes closed, and Short Falls Efficacy Scale-International. Feasibility was measured by recording class attendance and adverse events. RESULTS: Fifty-two participants completed follow-up assessments. The intervention group significantly improved compared with control group on standing balance (mean difference = 1.52 seconds, 95% CI 0.10-2.96, p = .04), sit-to-stand test (mean difference = -3.43 seconds, 95% CI -5.23 to -1.64, p < .001), 4-m walk (mean difference = -0.50 seconds, 95% CI -0.72 to -0.28, p < .001), and one-legged stand with eyes closed (mean difference = 1.93 seconds, 95% CI 0.40-3.46, p = .02). Average class attendance was 20 of 24 classes (83%). No serious adverse events occurred. CONCLUSIONS: This trial demonstrates the balance and mobility-related benefits and feasibility of Iyengar yoga for older people. The fall prevention effect of Iyengar yoga warrants further investigation.

BACKGROUND: Exercise interventions can enhance mobility after stroke as well as prevent falls in elderly persons. OBJECTIVE: Investigate whether an exercise intervention can enhance mobility, prevent falls, and increase physical activity among community-dwelling people after stroke. METHOD: A randomized trial with blinding of physical outcome assessment was conducted through local stroke clubs. Both groups, on average 5.9 years poststroke, received exercise classes, advice, and a home program for 12 months. The experimental group (EG) program (n = 76) aimed to improve walking, prevent falls and increase physical activity. The control group (CG) program (n = 75) aimed to improve upper-limb and cognitive functions. The primary outcomes were walking capacity, walking speed measured before and after the intervention, and fall rates monitored monthly. RESULTS: At 12 months, the EG walked 34 m further in 6 minutes (95% confidence interval [CI] = 19-50; P < .001) and 0.07 m/s faster over 10 m (95% CI = 0.01-0.14; P = .03) than the CG. The EG had 129 falls, and the CG had 133. There were no differences in proportion of fallers (relative risk = 1.22; 95% CI = 0.91-1.62; P = .19) or the rate of falls between groups (incidence rate ratio = 0.96; 95% CI = 0.59-1.51; P = .88). CONCLUSION: The experimental intervention delivered through stroke clubs enhanced aspects of mobility but had no effect on falls.

Aim. To investigate predictors of adherence to group-based exercise and physical activity participation among stroke survivors. Methods. 76 stroke survivors participated (mean age 66.7 years). Adherence was the percentage of classes attended over one year. Physical activity was the average pedometer steps/day measured over seven days at the end of the trial. Possible predictors included baseline measures of demographics, health, quality of life, falls, fear of falling, cognition, and physical functioning. Results. Mean class attendance was 60% (SD 29%). Only one variable (slow choice stepping reaction time) was an independent predictor of higher class attendance, explaining 5% of the variance. Participants completed an average of 4,365 steps/day (SD 3350). Those with better physical functioning (choice stepping reaction time, postural sway, maximal balance range, 10-m walk, or 6-min walk) or better quality of life (SF-12 score) took more steps. A model including SF-12, maximal balance range, and 6-min walk accounted for 33% of the variance in average steps/day. Conclusions. The results suggest that better physical functioning and health status are predictors of average steps taken per day in stroke survivors and that predicting adherence to group exercise in this group is difficult.
RESUMEN
OBJECTIVE: To develop and internally validate a falls prediction tool for people being discharged from inpatient aged care rehabilitation. STUDY DESIGN AND SETTING: Prospective cohort study. Possible predictors of falls were collected for 442 aged care rehabilitation inpatients at two hospitals. RESULTS: One hundred fifty participants fell in the 3 months after discharge from rehabilitation (34% of 438 with follow-up data). Predictors of falls were male gender (odds ratio [OR] 2.32, 95% confidence interval [CI]=1.00-4.03), central nervous system medication prescription (OR 2.04, 95% CI=1.00-3.30), and increased postural sway (OR 1.93, 95% CI=1.00-3.26). This three-variable model was adapted for clinical use by unit weighting (i.e., a score of 1 for each predictor present). The area under the receiver operating characteristic curve (AUC) for this tool was 0.69 (95% CI=0.64-0.74, bootstrap-corrected AUC=0.69). There was no evidence of lack of fit between prediction and observation (Hosmer-Lemeshow P=0.158). CONCLUSION: After external validation, this simple tool could be used to quantify the probability with which an individual will fall in the 3 months after an aged care rehabilitation stay. It may assist in the discharge process by identifying high-risk individuals who may benefit from ongoing assistance or intervention.
