Digital Apps to Improve Mobility in Adults with Neurological Conditions: A Health App-Focused Systematic Review.

The provision of mobility exercises through a smartphone application (app) for people undertaking neurological rehabilitation may improve mobility outcomes. However, it is difficult for clinicians and consumers to select high-quality, appropriate apps. This review aimed to identify (1) which mobile health (mHealth) apps are suitable for prescribing mobility exercises for adults with neurological health conditions, (2) how well these apps incorporate telehealth strategies, and (3) how well these apps rate in terms of quality and capacity for behaviour change. The Australian Apple iTunes Store was systematically searched, by using a search code and manually, for apps suitable for training mobility in neurological rehabilitation. Additional searches were conducted in known app repositories and for web-based apps. Trained reviewers extracted data from the included apps, including population-specific characteristics; quality, by using the Mobile App Rating Scale (MARS); and behaviour change potential, by using the App Behaviour Change Scale (ABACUS). The included apps (n = 18) provided <50 to >10,000 exercises, many incurred a subscription fee (n = 13), and half included telehealth features. App quality was moderate (mean MARS score of 3.2/5 and SD of 0.5), and potential for behaviour change was poor (mean ABACUS score of 5.7/21 and SD of 2.1). A limited number of high-quality apps are available for the prescription of mobility exercises in people with neurological conditions.

Use of behavior change techniques in physical activity programs and services for older adults: findings from a rapid review.

BACKGROUND: Understanding behavior change techniques (BCTs) used in randomized controlled trials (RCTs) of physical activity programs/services for older adults can help us to guide their implementation in real-world settings. PURPOSE: This study aims to: (a) identify the number and type of BCTs used in physical activity programs/services for older adults evaluated in large, good quality RCTs and (b) explore the impact of different BCTs on different outcome domains. METHODS: This is a secondary data analysis of a WHO-commissioned rapid review of physical activity programs/services for older adults. Fifty-six trials testing 70 interventions were coded for the type and number of BCTs present using a published BCT taxonomy. The proportion of positive effects found from physical activity interventions using the most common BCTs was calculated for the outcomes of physical activity, intrinsic capacity, functional ability, social domain, cognitive and emotional functioning, and well-being and quality of life. RESULTS: Thirty-nine of the 93 possible BCTs were identified in the included trials and 529 BCTs in total (mean 7.6, range 2-17). The most common BCTs were "action planning" (68/70 interventions), "instructions on how to perform a behavior" (60/70), "graded tasks" (53/70), "demonstration of behavior" (44/70), and "behavioral practice/rehearsal" (43/70). Interventions that used any of the most common BCTs showed overwhelmingly positive impacts on physical activity and social domain outcomes. CONCLUSION: Consideration of which BCTs are included in interventions and their impact on outcomes can improve the effectiveness and implementation of future interventions. To enable this, providers can design, implement, and evaluate interventions using a BCT taxonomy.

Interventions aimed at modifying health-related behaviors, such as physical activity, are often complex, with numerous components. To better understand interventions' "active ingredients," we conducted a secondary analysis of a World Health Organization (WHO)-commissioned rapid review, using a behavior change technique (BCT) taxonomy. We aimed to classify the number and types of BCTs in physical activity programs for older adults, as identified in randomized controlled trials (RCTs), and examine their impact on outcomes, including physical activity, intrinsic capacity, functional ability, social domain, cognitive and emotional functioning, and well-being. Examining 56 trials testing 70 interventions, we identified 39 out of 93 possible BCTs, totaling 529 instances across interventions. Common BCTs included "action planning," "instructions on how to perform a behavior," "graded tasks," "demonstration of behavior," and "behavioral practice/rehearsal." Interventions using the 10 most common BCTs demonstrated overwhelmingly positive impacts on physical activity and social domain outcomes. However, these BCTs were not consistently present in interventions yielding positive outcomes in other domains, with greater variation in effects. Our study highlights the significance of identifying both BCTs and desired outcomes when designing physical activity interventions. We advocate for the use of a taxonomy in designing and implementing future programs to maximize effectiveness.

Monitoring falls in residential aged care facilities: Agreement between falls incident reports and progress notes.

OBJECTIVES: Accurate fall reporting is essential for assessing the effectiveness of fall prevention strategies. This study aimed to investigate the level of agreement between incident reports and resident progress notes as data sources for falls monitoring in residential aged care facilities. METHODS: A retrospective observational study was conducted involving 46 older people from six residential aged care facilities who had consented to join the broader TOP UP trial. Fall events documented in the incident report system and resident progress notes over 12 months before randomisation were extracted by two independent reviewers using a standardised Excel form. Agreement between the two data collection methods was calculated using Cohen's kappa coefficient. RESULTS: A total of 75 falls were recorded from 27 (59%) of the 46 participants who were 65% female, with an average age of 83 [SD 9] years. The incident reports captured 68 (90.7%) falls, while the progress notes captured 73 (97.3%) falls. Overall, there was a 75% agreement between falls recorded in progress notes and incident reports. Perfect agreement was identified for five facilities (n = 35), while one facility had a lower agreement rate of 29% (n = 11), which appeared to be attributable to staff shortages linked to the COVID-19 pandemic. CONCLUSIONS: There was substantial agreement between incident reports and progress records. These findings support the use of incident reports for identifying falls in research or to investigate the effectiveness of fall prevention strategies in residential aged care facilities.

Promotion of physical activity by health professionals in a sample of six public hospitals: A cross sectional study.

ISSUE ADDRESSED: Despite strong evidence of physical and mental health benefits from physical activity, participation is low. Physical activity promotion by health professionals can effectively increase physical activity participation. This study aimed to explore the frequency of physical activity promotion by health professionals in public hospitals with a focus on community-based structured exercise; and facilitators and barriers to such promotion. METHODS: We surveyed health professionals (n = 100) from physiotherapy, rheumatology and rehabilitation departments at six public hospitals in Sydney, Australia. RESULTS: Most common respondent characteristics were physiotherapist (84%), female (68%), aged 25-34 years (45%) and treating older adults (45%). Almost all health professionals (94%) considered themselves physical activity role-models. Half (53%) reported promoting physical activity frequently/often to their clients. Those working with children with a physical disability (23%) were more likely to promote physical activity (Relative Risk 1.69, 95% CI 1.13-2.51, p = .03), than those working with adults or older adults. Half the physiotherapists (52%) reported providing tailored advice about increasing physical activity frequently/often, but only 20% provided advice about structured physical activity. Barriers reported by physiotherapists were lack of time (51%) and client's access to transport (61%). CONCLUSION: Only half the health professionals surveyed offered tailored physical activity advice to clients, and advice on structured physical activity was less common. SO WHAT?: Some promotion of physical activity by health professionals is occurring in hospital settings but more work is needed to embed this within clinical care.

Exercise Interventions Delivered Through Telehealth to Improve Physical Functioning for Older Adults with Frailty, Cognitive, or Mobility Disability: A Systematic Review and Meta-Analysis.

Introductions: This study assessed the effects of telehealth-delivered exercise interventions on physical functioning for older adults and explored implementation measures related to program delivery. Methods: We conducted a systematic review of studies investigating effects of exercise interventions delivered through telehealth in adults 60+ years of age with frailty, mobility, or cognitive disability on mobility, strength, balance, falls, and quality of life (QoL). Electronic databases (MEDLINE, CINAHL, SPORTSDiscus, and Physiotherapy Evidence Database) were searched from inception until May 2022. Evidence certainty was assessed with Grading of Recommendations, Assessment, Development, and Evaluation and meta-analysis summarized study effects. Results: A total of 11 studies were included, 5 randomized controlled trials, 2 pilot studies, and 4 feasibility studies. The overall certainty of evidence was rated as "low" or "very low." Pooled between-group differences were not statistically significant, but effect sizes suggested that telehealth produced a moderate improvement on mobility (n = 5 studies; standardized mean difference [SMD] = 0.63; 95% confidence interval [CI] = -0.25 to 1.51; p = 0.000, I2 = 86%) and strength (n = 4; SMD = 0.73; 95% CI = -0.10 to 1.56; p = 0.000, I2 = 84%), a small improvement on balance (n = 3; SMD = 0.40; 95% CI = -035 to 1.15; p = 0.012, I2 = 78%), and no effect on QoL. Analysis of implementation measures suggested telehealth to be feasible in this population, given high rates of acceptability and adherence with minimal safety concerns. Discussion: Telehealth may provide small to moderate benefits on a range of physical outcomes and appears to be well received in aged care populations.

Responsiveness of Patient-Reported and Device-Based Physical Activity Measures: Secondary Analysis of Four Randomized Trials.

PURPOSE: This study aimed to compare the responsiveness of patient-reported and device-based instruments within four physical activity trials. METHODS: This was a secondary analysis of four randomized trials that used both a patient-reported outcome measure (the Incidental and Planned Exercise Questionnaire (IPEQ)) and a device-based instrument (ActiGraph or ActivPAL) to measure physical activity. The four trials included were (i) Activity and MObility UsiNg Technology (AMOUNT), digitally enabled exercises in those undertaking aged care and neurological rehabilitation; (ii) Balance Exercise Strength Training at Home, home-based balance and strength exercises in community-dwelling people 65 yr or older; (iii) Coaching for Healthy Ageing (CHAnGE), physical activity coaching and fall prevention intervention in community-dwelling people 60 yr or older; and (iv) Fitbit trial, fall prevention and physical activity promotion with health coaching and activity monitor in community-dwelling people 60 yr or older. We estimated treatment effects for all variables within each physical activity instrument using regression analyses and expressed results as effect sizes (ES). RESULTS: Overall, device-based instruments were more responsive among healthy older adults (ES range, 0.01 to 0.32), whereas the IPEQ was more responsive among adults requiring rehabilitation (ES range, -0.06 to 0.35). Both the IPEQ and device-based instruments were more responsive in trials that promoted walking via coaching participants to increase their daily steps (AMOUNT (ES range, -0.06 to 0.35), CHAnGE (ES range, -0.24 to 0.22), and Fitbit trial (ES range, -0.23 to 0.32)). Individual variables within the IPEQ and device-based instruments varied in their responsiveness (ES range, -0.13 to 0.20). CONCLUSIONS: Both the IPEQ and device-based instruments are able to detect small changes in physical activity levels. However, responsiveness varies across different interventions and populations. Our findings provide guidance for researchers and clinicians in selecting an appropriate instrument to measure changes in physical activity.

Effects of sport or physical recreation for adults with physical or intellectual disabilities: a systematic review with meta-analysis.

OBJECTIVES: To evaluate the effects of sport or physical recreation on participation, mobility and quality of life for adults living with disabilities. DESIGN: Systematic review with meta-analysis. DATA SOURCES: Six databases searched from inception to May 2022. ELIGIBILITY CRITERIA: Randomised controlled trials including adults living with a physical or intellectual disability, comparing sport or physical recreation to non-active control. RESULTS: Seventy-four trials (n=2954; mean age 55 years) were included. Most (70) trials included people with physical disabilities, none evaluated sport and the most common physical recreation activities tested were traditional Chinese exercise (35%), yoga (27%) and dance (18%). Mean frequency and duration was 65 min/session, two times per week for 13 weeks. Most (86%) interventions were led by people with experience and/or training in the recreation activity, and only 37% reported leader experience and/or training working with people with disabilities. Participation was measured as attendance (mean 81%, 30 intervention groups). Physical recreation improved mobility (standardised mean difference (SMD) 0.38, 95% CI 0.07 to 0.69, n=469) and walking endurance (mean difference (MD) 40.3 m, 95% CI 19.5 to 61.1, n=801) with low certainty evidence and balance (Berg Balance Scale, range 0-56 points; MD 3.4 points, 95% CI 2.3 to 4.4, n=906) and quality of life (physical health; SMD 0.37, 95% CI 0.02 to 0.72, n=468) with very low certainty evidence, but not walking speed (MD 0.03 m/s, 95% CI -0.05 to 0.11, n=486). CONCLUSION: Physical recreation may confer multiple benefits for people living with disabilities regardless of the activity chosen, thus offering a potentially enjoyable and scalable strategy to increase physical activity.

Implementation of digital health interventions in rehabilitation: A scoping review.

OBJECTIVE: Digital health interventions have potential to enhance rehabilitation services by increasing accessibility, affordability and scalability. However, implementation of digital interventions in rehabilitation is poorly understood. This scoping review aims to map current strategies, research designs, frameworks, outcomes and determinants used to support and evaluate the implementation of digital interventions in rehabilitation. DATA SOURCES: Comprehensive searches from inception until October 2022 of MEDLINE, CINAHL, PsycINFO, PEDro, SpeechBITE, NeuroBITE, REHABDATA, WHO International Clinical Trial Registry and the Cochrane Library. METHODS: Two reviewers screened studies against the eligibility criteria. Implementation science taxonomies and methods, including Powell et al.'s compilation of implementation strategies, were used to guide analysis and synthesis of findings. RESULTS: The search retrieved 13,833 papers and 23 studies were included. Only 4 studies were randomised controlled trials and 9 studies (39%) were feasibility studies. Thirty-seven discrete implementation strategies were reported across studies. Strategies related to training and educating clinicians (91%), providing interactive assistance (61%), and developing stakeholder interrelationships (43%) were most frequently reported. Few studies adequately described implementation strategies and methods for selecting strategies. Almost all studies measured implementation outcomes and determinants; most commonly, acceptability, compatibility and dose delivered of digital interventions. CONCLUSION: The rigour of implementation methods in the field is currently poor. Digital interventions require carefully planned and tailored implementation to facilitate successful adoption into rehabilitation practice. To keep pace with rapidly advancing technology, future rehabilitation research should prioritise using implementation science methods to explore and evaluate implementation while testing effectiveness of digital interventions.

Physical Activity Preferences of People Living with Brain Injury: Formative Qualitative Research to Develop a Discrete Choice Experiment.

BACKGROUND AND OBJECTIVE: The World Health Organization physical activity guidelines for people living with disability do not consider the needs of people living with moderate-to-severe traumatic brain injury. This paper describes the qualitative co-development of a discrete choice experiment survey to inform the adaption of these guidelines by identifying the physical activity preferences of people living with moderate-to-severe traumatic brain injury in Australia. METHODS: The research team comprised researchers, people with lived experience of traumatic brain injury and health professionals with expertise in traumatic brain injury. We followed a four-stage process: (1) identification of key constructs and initial expression of attributes, (2) critique and refinement of attributes, (3) prioritisation of attributes and refinement of levels and (4) testing and refining language, format and comprehensibility. Data collection included deliberative dialogue, focus groups and think-aloud interviews with 22 purposively sampled people living with moderate-to-severe traumatic brain injury. Strategies were used to support inclusive participation. Analysis employed qualitative description and framework methods. RESULTS: This formative process resulted in discarding, merging, renaming and reconceptualising attributes and levels. Attributes were reduced from an initial list of 17 to six: (1) Type of activity, (2) Out-of-pocket cost, (3) Travel time, (4) Who with, (5) Facilitated by and (6) Accessibility of setting. Confusing terminology and cumbersome features of the survey instrument were also revised. Challenges included purposive recruitment, reducing diverse stakeholder views to a few attributes, finding the right language and navigating the complexity of discrete choice experiment scenarios. CONCLUSIONS: This formative co-development process significantly improved the relevance and comprehensibility of the discrete choice experiment survey tool. This process may be applicable in other discrete choice experiment studies.

Implementing digital devices to increase mobility training for people receiving inpatient rehabilitation: protocol for a feasibility hybrid type II randomized controlled trial.

BACKGROUND: People with mobility limitations can benefit from rehabilitation programs incorporating intensive, repetitive, and task-specific exercises using digital devices such as virtual reality gaming systems, tablet and smartphone applications, and wearable devices. The Activity and MObility UsiNg Technology (AMOUNT) rehabilitation trial (n = 300) showed improvements in mobility in people using these types of digital devices in addition to their usual rehabilitation care when the intervention was provided by an additional study-funded physiotherapist. However, it is not clear if this intervention can be implemented by hospital physiotherapists with a usual clinical load. The AMOUNT Implementation trial aims to explore the feasibility of conducting a large-scale implementation trial. METHODS: A pragmatic, assessor blinded, feasibility hybrid type II randomized controlled trial will be undertaken at a public hospital in Australia. There will be two phases. Phase I (Implementation phase) will involve implementing the digital devices into physiotherapy practice. Physiotherapists from the rehabilitation ward will receive a multifaceted implementation strategy guided by the Capabilities, Opportunities, Motivation-Behaviour (COM-B) theoretical model. The implementation strategy includes identifying and training a clinical champion; providing digital devices and education and training; facilitating use of the devices through clinical reasoning sessions and journal clubs; and audit and feedback of exercise dosage documentation. Phase II (Trial phase) will involve randomising 30 eligible inpatients from the same ward into either usual care or usual care plus an additional 30 min or more of exercises using digital devices. This intervention will be provided by the physiotherapists who took part in the implementation phase. We will collect data on feasibility, implementation, and patient-level clinical outcomes. The three primary outcome measures are the extent to which physiotherapists document the dosage of exercises provided to participants (feasibility criteria: exercise practice sheets complete for ≥85% of all participants); ability to recruit participants; and fidelity to the protocol of using digital devices to prescribe exercises (feasibility criteria: average of ≥ 30mins per day for > 50% intervention participants). DISCUSSION: This feasibility study will provide important information to guide the planning and conduct of a future large-scale implementation trial.

The effect of physical activity on health outcomes in people with moderate-to-severe traumatic brain injury: a rapid systematic review with meta-analysis.

BACKGROUND: In 2020, the World Health Organization (WHO) released the first global physical activity and sedentary behaviour guidelines for children and adults living with disability. The evidence informing the guidelines though is not specific to people living with traumatic brain injury (TBI), but rather comes from other disabling conditions such as Parkinson's disease, and stroke. There remains a clear lack of direct evidence of the effects of physical activity for people living with TBI. The objective of this rapid review was to identify direct evidence of the effect of physical activity on health outcomes in people with moderate-to-severe TBI to inform adaptation of the WHO physical activity guidelines into clinical practice guidelines. METHODS: We conducted a rapid systematic review with meta-analysis of randomised controlled trials, including people of any age with moderate-to-severe TBI, investigating physical activity interventions compared to either usual care, a physical activity intervention with different parameters, or a non-physical activity intervention. Four databases (CENTRAL, SPORTDiscus, PEDro, Ovid MEDLINE) were searched from inception to October 8, 2021. The primary outcomes were physical function, cognition, and quality of life. RESULTS: Twenty-three studies were included incorporating 812 participants (36% females, majority working-age adults, time post-TBI in studies ranged from 56 days (median) to 16.6 years (mean)). A range of physical activity interventions were evaluated in rehabilitation (n = 12 studies), community (n = 8) and home (n = 3) settings. We pooled data from the end of the intervention for eight outcomes. Participation in a virtual reality physical activity intervention improved mobility, assessed by the Community Balance and Mobility Scale (range 0 to 96; higher score indicates better mobility) more than standard balance training (two studies, 80 participants, Mean Difference = 2.78, 95% CI 1.40 to 4.16; low certainty evidence). There was uncertainty of effect for the remaining outcomes, limited by small sample sizes, diverse comparators and a wide range of outcome measures. CONCLUSION: This review consolidates the current evidence base for the prescription of physical activity for people with moderate-to-severe TBI. There remains a pressing need for further rigorous research in order to develop practice guidelines to support clinical decision-making when prescribing physical activity in this population.

Effect of sport on health in people aged 60 years and older: a systematic review with meta-analysis.

OBJECTIVES: To summarise evidence of benefits of sport for health among people aged 60+. DESIGN: Systematic review with meta-analysis of randomised controlled trials (RCTs). DATA SOURCES: Medline, CINAHL, SPORTDiscus, the Physiotherapy Evidence Database from inception to April 2021. STUDY SELECTION: RCTs investigating the effect of sport on health-related outcomes in people aged 60+ compared with non-active control. DATA SYNTHESIS AND ANALYSIS: Pooled effect sizes were calculated using random-effect models. Standardised mean differences (SMD), and mean difference (MD) were calculated. The Grading of Recommendations Assessment, Development and Evaluation system was used to assess the certainty of the evidence for analyses with ≥3 studies. RESULTS: Nine trials (628 participants) reported in 15 articles were included. Participation in sport improved cardiorespiratory fitness (n=5 trials; SMD=0.43, 95% CI 0.17 to 0.70; low certainty evidence), physical function (n=4; SMD=0.62, 95% CI 0.05 to 1.18; very low certainty evidence), and mental health (n=2; SMD=0.28, 95% CI 0.06 to 0.51) and reduced fat mass (n=6; MD=-0.99 kg, 95% CI -1.75kg to -0.23 kg; low certainty evidence) among older people. We found no significant effects of sport on overall physical activity participation, strength, balance, lean mass and bone mineral density (BMD). One study investigating quality of life reported a positive, but non-significant effect of sport. CONCLUSION: Sport may have a positive impact on health outcomes in people aged 60+. There was uncertainty on the effect of sport on strength, balance, lean mass and BMD. Further research is needed to investigate the optimal type and dose of sport to maximise the long-term benefits among older people.

Economic evaluation of digitally enabled aged and neurological rehabilitation care in the Activity and MObility UsiNg Technology (AMOUNT) trial.

OBJECTIVE: To investigate the trial-based cost-effectiveness of the addition of a tailored digitally enabled exercise intervention to usual care shown to be clinically effective in improving mobility in the Activity and MObility UsiNg Technology (AMOUNT) rehabilitation trial compared to usual care alone. DESIGN: Economic evaluation alongside a pragmatic randomized controlled trial. PARTICIPANTS: 300 people receiving inpatient aged and neurological rehabilitation were randomized to the intervention (n = 149) or usual care control group (n = 151). MAIN MEASURES: Incremental cost effectiveness ratios were calculated for the additional costs per additional person demonstrating a meaningful improvement in mobility (3-point in Short Physical Performance Battery) and quality-adjusted life years gained at 6 months (primary analysis). The joint probability distribution of costs and outcomes was examined using bootstrapping. RESULTS: The mean cost saving for the intervention group at 6 months was AU$2286 (95% Bootstrapped cost CI: -$11,190 to $6410) per participant; 68% and 67% of bootstraps showed the intervention to be dominant (i.e. more effective and cost saving) for mobility and quality-adjusted life years, respectively. The probability of the intervention being cost-effective considering a willingness to pay threshold of AU$50,000 per additional person with a meaningful improvement in mobility or quality-adjusted life year gained was 93% and 77%, respectively. CONCLUSIONS: The AMOUNT intervention had a high probability of being cost-effective if decision makers are willing to pay AU$50,000 per meaningful improvement in mobility or per quality-adjusted life year gained, and a moderate probability of being cost-saving and effective considering both outcomes at 6 months post randomization.

Physiotherapy-led telehealth and exercise intervention to improve mobility in older people receiving aged care services (TOP UP): protocol for a randomised controlled type 1 hybrid effectiveness-implementation trial.

Introduction: Deteriorating mobility and falls reduce independence and quality of life for older people receiving aged care services. This trial aims to establish effectiveness on the mobility of older people, and explore cost-effectiveness and implementation of a telehealth physiotherapy programme. Method and analysis: This type 1 hybrid effectiveness-implementation randomised controlled trial will involve 240 people aged 65+ years receiving aged care services in community or residential settings. Participants will be randomised to either: (1) the Telehealth Physiotherapy for Older People (TOP UP) Program or (2) a wait-list control group. The 6-month intervention includes 10 physiotherapy sessions delivered by videocall (Zoom). The intervention will include the local support of an aged care worker and online exercise resources. Primary outcome is mobility at 6 months post randomisation measured by the Short Physical Performance Battery. Secondary outcomes include rate of falls, sit-to-stand, quality of life, and goal attainment at 6 months after randomisation. Regression models will assess the effect of group allocation on mobility and the other continuously scored secondary outcomes, adjusting for baseline scores. The number of falls per person over 6 months will be analysed using negative binomial regression models to estimate between-group differences. An economic analysis will explore the cost-effectiveness of the TOP UP programme compared with usual care. Implementation outcomes and determinants relating to the intervention's reach, fidelity, exercise dose delivered, adoption, feasibility, acceptability, barriers and facilitators will be explored using mixed methods. Conclusion: This is the first trial to investigate the effectiveness, cost-effectiveness and implementation of a physiotherapy intervention in aged care delivered solely by telehealth internationally. The study has strong aged care co-design and governance and is guided by steering and advisory committees that include staff from aged care service providers and end-users. Trial results will be disseminated via peer-reviewed articles, conference presentations and lay summaries. Trial registration number: The trial is registered with the Australian New Zealand Clinical Trials Registry (ACTRN 12621000734864).

Ballistic resistance training has a similar or better effect on mobility than non-ballistic exercise rehabilitation in people with a traumatic brain injury: a randomised trial.

QUESTIONS: In people recovering from traumatic brain injury, is a 3-month ballistic resistance training program targeting three lower limb muscle groups more effective than non-ballistic exercise rehabilitation for improving mobility, strength and balance? Does improved mobility translate to better health-related quality of life? DESIGN: A prospective, multicentre, randomised trial with concealed allocation, intention-to-treat analysis and blinded measurement. PARTICIPANTS: A total of 144 people with a neurological movement disorder affecting mobility as a result of traumatic brain injury. INTERVENTION: For 3 months, the experimental group had three 60-minute sessions of non-ballistic exercise rehabilitation per week replaced by ballistic resistance training. The control group had non-ballistic exercise rehabilitation of equivalent time. The non-ballistic exercise rehabilitation consisted of balance exercises, lower limb stretching, conventional strengthening exercises, cardiovascular fitness training and gait training. OUTCOME MEASURES: The primary outcome was mobility measured using the High-Level Mobility Assessment Tool (HiMAT). Secondary outcomes were walking speed, strength, balance and quality of life. They were measured at baseline (0 months), after completion of the 3-month intervention (3 months) and 3 months after cessation of intervention (6 months). RESULTS: After 3 months of ballistic resistance training, the experimental group scored 3 points (95% CI 0 to 6) higher on the 54-point HiMAT than the control group and remained 3 points (95% CI -1 to 6) higher at 6 months. Although there was a transient decrement in balance at 3 months in the experimental group, the interventions had similar effects on all secondary outcomes by 6 months. Participants with a baseline HiMAT < 27 gained greater benefit from ballistic training: 6 points (1 to 10) on the HiMAT. CONCLUSION: This randomised trial shows that ballistic resistance training has a similar or better effect on mobility than non-ballistic training in people with traumatic brain injury. It may be better targeted towards those with more severe mobility limitations. TRIAL REGISTRATION: ACTRN12611001098921.

Impact of physical activity programs and services for older adults: a rapid review.

BACKGROUND: Knowledge of which physical activity programs are most effective for older adults in different sub-populations and contexts is limited. The objectives of this rapid review were to: 1) Overview evidence evaluating physical activity programs/services for older adults; and 2) Describe impact on physical activity, falls, intrinsic capacity (physical domain), functional ability (physical, social, and cognitive/emotional domains), and quality of life. METHODS: We conducted a rapid review of primary studies from 350 systematic reviews identified in a previous scoping review (March 2021: PEDro, MEDLINE, CINAHL, Cochrane Database). For Objective 1, we included intervention studies investigating physical activity programs/services in adults ≥ 60 years. Of these, we included good quality (≥ 6/10 PEDro scale) randomised controlled trials (RCTs) with ≥ 50 participants per group in Objective 2. RESULTS: Objective 1: Of the 1421 intervention studies identified from 8267 records, 79% were RCTs, 87% were in high income countries and 39% were good quality. Objective 2: We identified 87 large, good quality RCTs (26,861 participants). Overall activity promotion, structured exercise and recreation/sport had positive impacts (≥ 50% between-group comparisons positive) across all outcome domains. For overall activity promotion (21 intervention groups), greatest impacts were on physical activity (100% positive) and social outcomes (83% positive). Structured exercise (61 intervention groups) had particularly strong impacts on falls (91% positive), intrinsic capacity (67% positive) and physical functioning (77% positive). Recreation/sport (24 intervention groups) had particularly strong impacts on cognitive/emotional functioning (88% positive). Multicomponent exercise (39 intervention groups) had strong impacts across all outcomes, particularly physical activity (95% positive), falls (90% positive) and physical functioning (81% positive). Results for different populations and settings are presented. CONCLUSION: Evidence supporting physical activity for older adults is positive. We outline which activity types are most effective in different populations and settings.
