ABSTRACT
OBJECTIVES: The Sunbeam trial significantly reduced falls in long-term aged care (LTC) residents. The current study's primary objective was to undertake subgroup analysis of the Sunbeam trial, to determine whether the intervention was effective for reducing falls in LTC residents with mild-moderate cognitive impairment/dementia. Secondary objectives were to determine intervention effects on cognitive and physical function. DESIGN: Subgroup analysis of a cluster randomized controlled trial (RCT). SETTING AND PARTICIPANTS: Permanent residents of LTC in Australia who participated in the Sunbeam trial with Addenbrooke's Cognitive Examination-Revised (ACE-R) scores <83 (Mini-Mental State Examination >14 = main trial inclusion criteria). METHODS: Of 221 participants, 148 had an ACE-R <83 and were included in this study. Sixteen LTC residences (clusters) were randomized to receive either the Sunbeam program or usual care. The Sunbeam program involved two 1-hour sessions/week of tailored and progressive resistance and balance training for 25 weeks followed by a maintenance program (two 30-min sessions/week of nonprogressive exercise for 6 months). Assessments were conducted at baseline, 6 months, and 12 months. Falls were recorded using routinely collected data from the LTC incident management systems. RESULTS: Rate of falls (50%) and risk of falls (31%), multiple falls (40%), and injurious falls (44%) were reduced in the intervention group. The intervention group had significantly better balance (static and dynamic) and sit-to-stand ability when compared with the control group at 6 months and significantly better dynamic balance at 12 months. There were no serious adverse events. CONCLUSIONS AND IMPLICATIONS: The Sunbeam Program significantly reduced falls and improved physical performance in cognitively impaired LTC residents. This is a novel and important finding, as many previous studies have excluded people with cognitive impairment/dementia and inconsistent findings have been reported when this population has been studied. Our findings suggest that progressive resistance and balance exercise is a safe and effective fall prevention intervention in LTC residents with mild-moderate cognitive impairment/dementia.

BACKGROUND AND PURPOSE: Low and slowing gait speeds among nursing home residents are linked to a higher risk of disability, cognitive impairment, falls, and mortality. A better understanding of the spatiotemporal parameters of gait that influence declining mobility could lead to effective rehabilitation and preventative intervention. The aims of this study were to objectively quantify the spatiotemporal characteristics of gait in the nursing home setting and define the relationship between these parameters and gait speed. METHODS: One hundred nursing home residents were enrolled into the study and completed 3 habitual gait speed trials over a distance of 3.66 m. Trials were performed using an instrumented gait analysis. The manner in which the spatiotemporal parameters predicted gait speed was examined by univariate and multivariable regression modeling. RESULTS: The nursing home residents had a habitual mean (SD) gait speed of 0.63 (0.19) m/s, a stride length of 0.83 (0.15) m, a support base of 0.15 (0.06) m, and step time of 0.66 (0.12) seconds. Multivariable linear regression revealed stride length, support base, and step time predicted gait speed (R = 0.89, P < .05). Step time had the greatest influence on gait speed, with each 0.1-second decrease in step time resulting in a 0.09 m/s (95% confidence interval, 0.08-0.10) increase in habitual gait speed. CONCLUSIONS: This study revealed step time, stride length, and support base are the strongest predictors of gait speed among nursing home residents. Future research should concentrate on developing and evaluating intervention programs that were specifically designed to focus on the strong predictors of gait speed in nursing home residents. We would also suggest that routine assessments of gait speed, and if possible their spatiotemporal characteristics, be done on all nursing home residents in an attempt to identify residents with low or slowing gait speed.

OBJECTIVE:: To estimate the cost-effectiveness of a strength and balance exercise programme (SUNBEAM) which has been shown to be clinically effective in reducing the rate of falls in residents of aged care facilities. DESIGN:: An economic evaluation was conducted alongside a pragmatic cluster randomized controlled trial that included 16 residential care facilities and 221 participants. Mean participant age was 86 years, 65% were female and 78% relied on a mobility aide. A cost-effectiveness analysis examined the costs of providing the exercise programme and costs of health service use arising from falls in each arm (intervention and usual care) over 12 months. MAIN MEASURES:: Incremental cost-effectiveness ratios were calculated for the cost per fall avoided. Costs were bootstrapped to obtain adjusted confidence intervals for the incremental cost-effectiveness ratios. RESULTS:: Of 63 facilities contacted, 16 met the eligibility criteria and were randomized to the intervention or usual care (1:1). There were 142 falls in the intervention group and 277 in the usual care group. 72 injurious falls occurred in the intervention group versus 157 with usual care. Delivery of the SUNBEAM programme cost $463 per participant. The mean total cost of each fall (regardless of group) was $400.09 and the mean cost of each injurious fall was $708.27. The incremental cost-effectiveness ratio was $22 per fall per person avoided with the mean bootstrapped incremental cost-effectiveness ratio $18 per fall avoided (95% CI: -$380.34 to $417.85). CONCLUSION:: The SUNBEAM programme can be considered cost-effective, relative to other fall-prevention interventions in older adults.

BACKGROUND: Falls prevention is an international priority, and residents of long-term aged care fall approximately 3 times more often than community dwellers. There is a relative scarcity of published trials in this setting. OBJECTIVES: Our objective was to undertake a randomized controlled trial to test the effect of published best practice exercise in long-term residential aged care. The trial was designed to determine if combined high level balance and moderate intensity progressive resistance training (the Sunbeam Program) is effective in reducing the rate of falls in residents of aged care facilities. METHOD: A cluster randomized controlled trial of 16 residential aged care facilities and 221 participants was conducted. The broad inclusion criterion was permanent residents of aged care. Exclusions were diagnosed terminal illness, no medical clearance, permanent bed- or wheelchair-bound status, advanced Parkinson's disease, or insufficient cognition to participate in group exercise. Assessments were taken at baseline, after intervention, and at 12 months. Randomization was performed by computer-generated sequence to receive either the Sunbeam program or usual care. A cluster refers to an aged care facility. INTERVENTION: The program consisted of individually prescribed progressive resistance training plus balance exercise performed in a group setting for 50 hours over a 25-week period, followed by a maintenance period for 6 months. OUTCOME MEASURES: The primary outcome measure was the rate of falls (number of falls and days followed up). Secondary outcomes included physical performance (Short Physical Performance Battery), quality of life (36-item Short-Form Health Survey), functional mobility (University of Alabama Life Space Assessment), fear of falling (Falls Efficacy Scale International), and cognition (Addenbrooke's Cognitive Evaluation-revised). RESULTS: The rate of falls was reduced by 55% in the exercise group (incidence rate ratio = 0.45, 95% confidence interval 0.17-0.74); an improvement was also seen in physical performance (P = .02). There were no serious adverse events. CONCLUSION: The Sunbeam Program significantly reduced the rate of falls and improved physical performance in residents of aged care. This finding is important as prior work in this setting has returned inconsistent outcomes, resulting in best practice guidelines being cautious about recommending exercise in this setting. This work provides an opportunity to improve clinical practice and health outcomes for long-term care residents.

This study investigated the association of sitting time with sarcopenia and physical performance in residential aged care residents at baseline and 18-month follow-up. Measures included the International Physical Activity Questionnaire (sitting time), European Working Group definition of sarcopenia, and the short physical performance battery (physical performance). Logistic regression and linear regression analyses were used to investigate associations. For each hour of sitting, the unadjusted odds ratio of sarcopenia was 1.16 (95% confidence interval [0.98, 1.37]). Linear regression showed that each hour of sitting was significantly associated with a 0.2-unit lower score for performance. Associations of baseline sitting with follow-up sarcopenia status and performance were nonsignificant. Cross-sectionally, increased sitting time in residential aged care may be detrimentally associated with sarcopenia and physical performance. Based on current reablement models of care, future studies should investigate if reducing sedentary time improves performance among adults in end of life care.

OBJECTIVE: To conduct a systematic review of published fall risk assessment tools (FRATs) tested for predictive validity among older adults in long-term care (LTC). METHODS: A systematic search was conducted using five databases. Only studies reporting on sensitivity and specificity values, conducted in LTC on populations primarily aged over 60 years, were considered. RESULTS: Fifteen papers were included and three different categories of FRATs emerged: multifactorial assessment tools, functional mobility assessments and algorithms. Several FRATs showed moderate-to-good predictive validity and reliability, with the Modified Fall Assessment Tool and the Peninsula Health Falls Risk Assessment Tool (PHFRAT) also demonstrating good feasibility. CONCLUSION: Evidence for the best choice of FRAT for use in LTC remains limited. Further research is warranted for the PHFRAT, recommended for use in LTC by best practice guidelines, before its establishment as the tool of choice for these clinical settings.

Once the general decline in muscle mass, muscle strength and physical performance falls below specific thresholds, the middle aged or older adult will be diagnosed as having sarcopenia (a loss of skeletal muscle mass and strength). Sarcopenia contributes to a range of adverse events in older age including disability, hospitalisation, institutionalisation and falls. One potentially relevant but understudied population for sarcopenia researchers would be Masters athletes. Masters sport is becoming more common as it allows athletes (typically 40 years and older) the opportunity to participate in individual and/or team sports against individuals of similar age. This study examined a variety of measures of anthropometric, physical function and general health markers in the male and female Masters athletes who competed at the 2014 Pan Pacific Masters Games held on the Gold Coast, Australia. Bioelectrical impedance analysis was used to collect body fat percentage, fat mass and fat-free mass; with body mass, height, body mass index (BMI) and sarcopenic status also recorded. Physical function was quantified by handgrip strength and habitual walking speed; with general health described by the number of chronic diseases and prescribed medications. Between group analyses utilised ANOVA and Tukey's post-hoc tests to examine the effect of age group (40-49, 50-59, 60-69 and >70 years old) on the outcome measures for the entire sample as well as the male and female sub-groups. A total of 156 athletes (78 male, 78 female; mean 55.7 years) provided informed consent to participate in this study. These athletes possessed substantially better anthropometric, physical function and general health characteristics than the literature for their less physically active age-matched peers. No Masters athletes were categorised as being sarcopenic, although one participant had below normal physical performance and six participants had below normal muscle strength. In contrast, significant age-related reductions in handgrip strength and increases in the number of chronic diseases and prescribed medications were observed for the overall cohort as well as the male and female sub-groups. Nevertheless, even those aged over 70 years only averaged one chronic disease and one prescribed medication. These results may suggest that participation in Masters sport helps to maintain anthropometry, physical function and general health in middle-aged and older adults. However, it is also possible that only healthier middle-aged and older adults with favourable body composition and physical function may be able to participate in Masters sport. Future research should therefore utilise longitudinal research designs to determine the health and functional benefits of Master sports participation for middle-aged and older adults.
ABSTRACT
BACKGROUND: Pilot work by our group has demonstrated that aquatic exercise has valuable functional and psychosocial benefits for adults living in the residential aged care setting with dementia. The aim of the currents study was to advance this work by delivering the Watermemories Swimming Club aquatic exercise program to a more representative population of older, institutionalized adults with dementia. METHODS: The benefits of 12 weeks of twice weekly participation in the Watermemories Swimming Club aquatic exercise program were assessed among an exercise and usual care control group of residential aged care adults with advanced dementia. A battery of physical and psychosocial measures were collected before and after the intervention period, and program implementation was also investigated. RESULTS: Seven residential aged care facilities of 24 approached, agreed to participate and 56 residents were purposefully allocated to exercise or control. Twenty-three participants per group were included in the final analysis. Both groups experienced decreases in skeletal muscle index and lean mass (p < 0.001), but exercise stifled losses in muscle strength and transition into sarcopenic. Behavioral and psychological symptoms of dementia and activities of daily living approached significance (p = 0.06) with positive trends observed across other psychosocial measures. CONCLUSIONS: This study demonstrates the value of exercise participation, and specifically aquatic exercise in comparison to usual care for older, institutionalized adults with advanced dementia. However, it also highlights a number of barriers to participation. To overcome these barriers and ensure opportunity to residents increased provider and sector support is required.

BACKGROUND: Confidence in findings can only be drawn from measurement tools that have sound psychometric properties for the population with which they are used. Within a dementia specific population, measures of physical function have been poorly justified in exercise intervention studies, with justification of measures based on validity or reliability studies from dissimilar clinical populations, such as people with bronchitis or healthy older adults without dementia. OBJECTIVES: To review the reliability and validity of quantitative measures of pre-identified physical function, as commonly used within exercise intervention literature for adults with dementia. INCLUSION CRITERIA TYPES OF PARTICIPANTS: Participants were adults, aged 65 years and older, with a confirmed medical diagnosis of dementia. TYPES OF INTERVENTION(S)/PHENOMENA OF INTEREST: n/a TYPES OF STUDIES: Desired studies were observational and cross-sectional and that assessed measures from a pre-identified list of measures of physical function. OUTCOMES: Studies that assessed the psychometric constructs of reliability and validity were targeted. COSMIN taxology was used to define reliability and validity. This included, but were not limited to, Intra-Class Correlations, Kappa, Cronbach's Alpha, Chi Squared, Standard Error of Measurement, Minimal Detectable Change and Limits of Agreement. SEARCH STRATEGY: Published material was sourced from the following four databases: MEDLINE, EMBASE, CINAHL and ISI Web of Science. Grey literature was searched for using ALOIS, Google Scholar and ProQuest. METHODOLOGICAL QUALITY: The COSMIN checklist was used to assess methodological quality of included studies. Assessment was completed by two reviewers independently. DATA EXTRACTION: Reliability and validity data was extracted from included studies using standardized Joanna Briggs Institute data collection forms. Extraction was completed by two reviewers. DATA SYNTHESIS: A narrative synthesis of measurement properties of the tools used to measure physical function was performed. Quantitative meta-analysis was conducted for Intra-Class Correlation Coefficients only. RESULTS: With respect to relative reliability, studies reporting assessed measures had intraclass correlation coefficients greater than 0.71, indicating their suitability for use at a group level. However, a consistent finding among studies that included assessment of absolute reliability was that intra individual variation was too large for meaningful measurement of individuals. This was indicated by large Minimal Detectable Change (MDC) scores. Walk Speed has the smallest reported Mimimal Detectable Change score at 0.11m/s. This represented a change of 35% before statistical variation could be eliminated as the cause for this change. All measures had large MDC values. Walk Speed had the smallest MDC values at 0.11m/s, which represented a necessary change of 35%. Only a limited number of studies assessed the validity of measures. This supports the use of these measures in a very narrow selection of circumstances (see Summary of Findings). CONCLUSIONS: In summary, measures have shown appropriate levels of relative reliability. This supports their use at the group level. However, large levels of intra-individual variation undermine their applicability at the individual level. Limited studies of validity were available to this review, which limits a conclusion on whether measures are valid for people with dementia.

The objective of the study was to examine the feasibility and benefits of a group resistance training exercise programme for improving muscle function in institutionalised older adults. A feasibility and acceptability study was designed for a residential aged care (RAC) facility, based on the Gold Coast, Australia. Thirty-seven adults, mean age 86.8 ± 6.1 years (30 females) living in a RAC facility. Participants were allocated into an exercise (n = 20) or control (n = 17) group. The exercise group, the Group Aged Care Exercise (GrACE) programme, performed 12 weeks of twice weekly resistance exercises. Feasibility was measured via recruitment rate, measurement (physiological and surveys) completion rate, loss-to-follow-up, exercise session adherence, adverse events, and ratings of burden and acceptability. Muscle function was assessed using gait speed, sit-to-stand and handgrip strength assessments. All intervention participants completed pre- and post-assessments, and the exercise intervention, with 85% (n = 17) of the group attending ≥ 18 of the 24 sessions and 15% (n = 3) attending all sessions. Acceptability was 100% with exercise participants, and staff who had been involved with the programme strongly agreed that the participants "Benefited from the programme." There were no adverse events reported by any participants during the exercise sessions. When compared to the control group, the exercise group experienced significant improvements in gait speed (F(4.078) = 8.265, p = 0.007), sit to stand performance (F(3.24) = 11.033, p = 0.002) and handgrip strength (F(3.697) = 26.359, p < 0.001). Resistance training via the GrACE programme is feasible, safe and significantly improves gait speed, sit-to-stand performance and handgrip strength in RAC adults.

OBJECTIVE: To quantify habitual walking speed and estimate the prevalence of low habitual walking speed (<0.8m/s and <0.5m/s) in nursing home residents; and secondarily to gain some insight into whether demographic, health, and functional outcomes could predict the nursing home residents' walking speed. DESIGN: Cross-sectional study. SETTING: Eleven nursing homes. PARTICIPANTS: Nursing home residents (N=102 [37%] of 273 eligible, randomly selected residents from 11 nursing homes consented to participate in this study). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The primary outcome was habitual walking speed assessed over a distance of 2.4m. Secondary outcomes including body composition, muscle strength, balance and physical performance as assessed via the Short Physical Performance Battery, and historical and current demographic and health measures were all assessed as potential predictors of walking speed. RESULTS: Mean walking speed was .37±.26 m/s, meaning that 97% and 75% of participants had walking speeds <0.8m/s and <0.5m/s, respectively. Multivariable linear regression identified physical activity status before 50 years of age and daily sitting time as independent predictors of walking speed (r(2)=.25, P<.05), although this regression only accounted for 25% of the variance in walking speed. CONCLUSIONS: Almost all participants in this study had below-normal walking speed, a known clinical predictor of physical performance. Because walking speed is a clinical marker of many age-related adverse outcomes in older age, efforts to increase or at least maintain walking speed in nursing home residents should be considered. Some evidence suggests that progressive resistance training may offset these declines in walking speed.

BACKGROUND: This pilot investigation aimed to assess the relative and absolute test-retest reliability of commonly used functional performance measures in older adults with dementia residing in residential aged care facilities. METHODS: A total of 12 participants were tested on the Short Physical Performance Battery (SPPB), the Balance Outcome Measure for Elder Rehab (BOOMER), hand grip strength, anthropometric measures and Bio-electric Impedance Analysis (BIA). This study utilized a seven-day test-retest evaluation. Intra-class Correlation Coefficients (ICC) were used to assess relative reliability, Typical Error of Measurement (TEM) was used to assess the absolute reliability, and Bland-Altman plots were used to assess group and individual levels of agreement. RESULTS: With the exception of Standing Balance (ICC = 0.49), 2.4-m walk (ICC = 0.68), functional reach (ICC = 0.38), and static timed standing (ICC = 0.47), all measures demonstrated acceptable (>0.71) ICCs. However, only the anthropometric measures demonstrated acceptable levels of absolute reliability (>10% TEM). Bland-Altman analysis showed non-significant (p > 0.05) mean differences, and eight out of the 17 measures showing wide Limits of Agreement (LoA). CONCLUSIONS: Current measures of functional performance are demonstrably inappropriate for use with a population of older adults with dementia. Authors suggest aligning current measurement strategies with Item Response Theory as a way forward.

BACKGROUND: Sarcopenia is a significant geriatric syndrome with both health care expenditure and personal burden. Most recently, the European Working Group in Sarcopenia in Older Adults has established a consensus definition and assessment criteria for sarcopenia that includes a below-normal muscle mass and muscle function (either or both of below-normal muscle strength and physical performance). Using these criteria, work is needed to identify the prevalence and risk factors among the old, and those most susceptible to sarcopenia, the very old. This manuscript describes the recruitment and data collection methodology, and direct burden to participants, among a very old cohort residing in a residential aged care (RAC) setting. METHODS: Eleven RAC facilities participated in the study. Potential participants were identified by the facility service manager and then randomised into the study. All participants gave self or substitute decision maker consent. Participants undertook a single one on one assessment that included measures of sarcopenia, functional capacity, cognitive and nutritional health, falls, activity, facility and hospital history, physical activity and assessment burden. A sub-study of physical activity and sedentary behaviours measured by activPAL3™ inclinometer was also conducted. RESULTS: Of 709 residents, 328 were ineligible to participate. Two hundred and seventy-three residents were randomised to the study and 102 gave informed or substitute decision maker consent. Participants were 84.5 ± 8.2 years of age and had been in care for 1,204.2 ± 1,220.1 days. The groups need for care was high (Aged Care Funding Instrument score of 2.6 ± 1.7) and they had a below-normal functional (Short Physical Performance Battery summery score of 3.5 ± 2.4). The larger percentage of participants had no depression and normal cognitive capacity. A total of 33 residents participated in the activPAL study. Each assessment took an average of 27.0 ± 7.0 min, with a low assessment burden reported by participants. CONCLUSIONS: The successful assessment of sarcopenia and physical activity in a RAC setting is labour intensive to establish, but feasible to conduct. Low recruitment numbers and the restrictive exclusion criteria, may have limited the accuracy of this work. However, this work is a primary step in establishing the level of sarcopenia and its risk factors for those in end-of-life care.
ABSTRACT
INTRODUCTION: Falls are common among older adults. It is reported that approximately 60% of residents of aged care facilities fall each year. This is a major cause of morbidity and mortality, and a significant burden for health care providers and the health system. Among community dwelling older adults, exercise appears to be an effective countermeasure, but data are limited and inconsistent among studies in residents of aged care communities. This trial has been designed to evaluate whether the SUNBEAM program (Strength and Balance Exercise in Aged Care) reduces falls in residents of aged care facilities. RESEARCH QUESTION: Is the program more effective and cost-effective than usual care for the prevention of falls? DESIGN: Single-blinded, two group, cluster randomized trial. PARTICIPANTS AND SETTING: 300 residents, living in 20 aged care facilities. INTERVENTION: Progressive resistance and balance training under the guidance of a physiotherapist for 6 months, then facility-guided maintenance training for 6 months. CONTROL: Usual care. MEASUREMENTS: Number of falls, number of fallers, quality of life, mobility, balance, fear of falling, cognitive well-being, resource use, and cost-effectiveness. Measurements will be taken at baseline, 6 months, and 12 months. ANALYSIS: The number of falls will be analyzed using a Poisson mixed model. A logistic mixed model will be used to analyze the number of residents who fall during the study period. Intention-to-treat analysis will be used. DISCUSSION: This study addresses a significant shortcoming in aged care research, and has potential to impact upon a substantial health care problem. Outcomes will be used to inform care providers, and guide health care policies.
