Background and purpose: Dementia affects physical as well as cognitive performance. In individuals with dementia (IWD), decline in physical performance increases with disease progression and is associated with higher functional dependence and decreased quality of life. It is paramount to examine factors that potentially preserve physical performance in IWD, particularly in light of conflicting findings on the effectiveness of physical activity interventions on physical performance of IWD, mainly due to limited number of high-quality studies, large heterogeneity in methods used, or insufficient reporting of methods. The aim of this study was to investigate the effects of a 16-week multimodal exercise program (MEP) combining physical and cognitive tasks on physical performance in IWD, and to identify individual characteristics of MEP responders.

Methods: A multicenter randomized controlled trial with assessment methods identified by an expert panel was conducted. We included 319 IWD of mild to moderate severity, older than 65 years, who underwent a standardized MEP specifically designed for IWD. At baseline and immediately after the MEP, we assessed physical performance (ie, mobility, balance, and strength) and function of lower extremities (primary outcomes). Potential effects of the MEP on physical performance were identified using 2-factor analyses of variance with repeated measurements within 2 samples (ie, intention-to-treat and per-protocol sample). Additionally, we compared characteristics related to physical performance between positive, non-, and negative responders.

Results and discussion: Neither analysis procedure revealed statistically significant time×group effects. However, 28% to 40% of participants were positive responders with regard to balance, and strength and function of lower extremities; and these persons had statistically significant lower baseline performance in the corresponding assessments.

Conclusions: This randomized controlled trial revealed no overall effects of the MEP on physical performance, probably due to high heterogeneity of the study sample. Findings in responder analysis showed that IWD with lower physical performance at baseline tended to benefit more than those with higher baseline performance. Thus, a higher degree of individualization of the MEP depending on baseline performance on IWD may improve overall MEP effectiveness.

Background and purpose: To evaluate the effectiveness of multicomponent functional maintenance initiatives (MFMIs) on functional outcomes and adverse events associated with functional decline among acutely hospitalized older adults.

Data sources: Studies were sourced from OVID Medline, PubMed, Embase, CINAHL, the Cochrane Library, and PEDro databases from inception to April 15, 2020, and their bibliographies.

Study selection: Randomized controlled trials were included if they investigated multicomponent interventions comprising more than one nonpharmacological intervention targeting physical functional decline and another shared risk factor for geriatric syndromes in acutely hospitalized medical or nonelective surgical patients 65 years and older.

Data extraction: Two reviewers independently assessed for eligibility, extracted data, and conducted risk of bias assessments.

Data synthesis: Eight studies involving 5534 patients were included. Multicomponent functional maintenance initiatives did not appear to confer significant effects on functional status, length of stay, or 30-day hospital readmissions; however, clinical heterogeneity limited meta-analysis for some specific functional outcomes. Patients who did not receive MFMIs were more likely to be discharged to a nursing staff facility (odds ratio = 1.53; 95% confidence interval, 1.23 to 1.90). No effect of MFMI on all-cause mortality was observed, and adverse events were rare and unlikely attributed to nonpharmacological interventions.

Conclusions: Data from a small number of studies suggest MFMIs reduce the likelihood of discharge to a nursing staff facility in acutely hospitalized older adults; however, this effect may not be driven via improvements in physical function. Standardized evaluation methods to determine MFMI effectiveness appear indicated to assist decision-making regarding their implementation in clinical practice.

Background and purpose: Falls are a leading cause of morbidity, mortality, loss of independence, and significant functional decline in aging populations. Effective interventions aimed at reducing the risk of falls, and preventing associated disability and functional decline, are needed to promote the health and wellness of older adults. Recent literature has found that an Otago-based exercise program (OBEP), which incorporates strengthening, balance, and walking, may not only decrease falls and fall risk among community-dwelling older adults but may also be effective among older adults residing in assisted living facilities (ALFs). The purpose of this study is to expand upon current research by comparing the outcomes of an OBEP and traditional physical therapy (TPT) in decreasing falls and the risk of falls among older adults living in an ALF. The authors hypothesized that traditional physical therapy would reduce fall risk and the number of falls in older adults residing in ALFs more than an OBEP.

Methods: This study conducted a 2-group retrospective chart review of 59 older adults living in an ALF from January 2013 to October 2018 who received either TPT (n = 29) or the OBEP (n = 30). Participants were a mean of 87 years old and were classified at risk for falls by the Tinetti Performance-Oriented Mobility Assessment (POMA). Primary variables included the number of falls prior to intervention, during intervention, and 1 year following intervention, as well as pre- and posttreatment Tinetti POMA scores. Efficacy was examined using multiple linear regression analysis.

Results and discussion: Both groups achieved reduced falls and increased POMA scores. Group assignment did not significantly predict performance in key outcome measures, namely the number of falls (P = .199) and Tinetti POMA scores (P = .063) following treatment.

Conclusions: These findings indicated that both an OBEP and tpt may be effective interventions for reducing falls and fall risk in the ALF setting.

Background and purpose: Older adults who live independently in the community are higher functioning and routinely ambulate in the community. Unrestricted community ambulation increases the likelihood of encountering precarious situations challenging balance. Sufficient dynamic balance is necessary to avoid falls. Currently used balance and mobility assessments may not sufficiently challenge dynamic balance to uncover mobility deficits in independent community-dwelling older adults. The purpose of this study was to investigate whether backward walking speed (BWS) can serve as an outcome measure to screen dynamic balance and mobility deficits in independent community-dwelling older adults.

Methods: A convenience sample of 30 older adults (73.68 ± 6.54 years) participated in this cross-sectional study. Participants walked backward on an instrumented walkway to record BWS. Other outcomes included forward walking speed (FWS), Community Balance and Mobility (CB&M) Scale, Falls Efficacy Scale-International (FES-I), Timed Up and Go (TUG) test, and 7-day average step count (ASC). A multivariate analysis of variance investigated the overall group differences between older adults at fall risk and those not at risk and was followed up by univariate tests. Pearson and spearman coefficients investigated associations between study outcomes. Youden's index assessed diagnostic accuracy.

Results and discussion: Backward walking speed, CB&M, FES-I, ASC discriminated older adults at fall risk from those not at risk (P < .01) whereas FWS and TUG did not. Backward walking speed strongly correlated with challenging assessments of balance and mobility (CB&M, FES-I, and ASC) but only moderately correlated with the TUG. The CB&M Scale independently explained 53% variance in the BWS performance (P < .01). Youden's index was highest (Y = 0.6, sensitivity = 93%, and specificity = 67%) for BWS (0.73 m/s) compared with other study outcomes.

Conclusions: Preliminary results suggest that BWS can screen for dynamic balance and mobility deficits in independent community-dwelling older adults. Accurate screening is the first step to capture early decline in function for independent community-dwelling older adults. Longitudinal follow-up studies are warranted to validate BWS as a screening tool.

Background and purpose: Movement quality of the lower extremities is considered an indicator of functional status in older adults with knee osteoarthritis (OA), and visual assessment of movement quality during functional movement tests can identify movement dysfunction and predict factors associated with lower extremity injuries. This study investigated the intertester and intratester reliability of trained testers for functional movement tests in community-dwelling older adults with knee OA.

Methods: This study was a cross-sectional study. A total of 43 older adults with knee OA were recruited for this study and performed 2 functional movement tests: squat and step-down. Movement quality during the functional movement tests was visually rated in segmental (trunk, pelvic, knee, and foot) and overall regions and was scored from 0 (acceptable) to 3 (marked dysfunction). Percentage of agreement and weighted κ coefficients were used to explore the reliability between and within testers.

Results: The intertester reliability of the functional movement tests showed weak to strong agreement (weighted κ values from 0.44 to 0.88); the percentage agreement ranged from 52.78% to 93.02%. The intratester reliability of the functional movement tests showed weak to strong agreement (weighted κ values from 0.57 to 0.88); the percentage agreement ranged from 69.77% to 93.02%.

Conclusions: Visual assessment of functional movement tests showed weak to strong intertester and intratester reliability to examine movement quality in community-dwelling older adults with knee OA. Thus, while it may be useful in a clinical setting to assess movement dysfunction segmentally and generally in older adults with knee OA; greater efforts would be needed to ensure high levels of agreement of functional movement tests.

Background and purpose: Despite evidence that falls can be prevented with specific exercise interventions such as the Otago Exercise Program (OEP), translation of these programs into practice is limited in rural and medically underserved areas. The Community Health and Mobility Partnership (CHAMP) addresses this problem through a community-based implementation of the OEP in rural Appalachia where medical resources are scarce. The purpose of this study was to examine the effects of the CHAMP on physical performance and balance confidence in community-dwelling older adults.

Methods: This study was a retrospective analysis of quasi-longitudinal data. Older adults received fall screenings at local senior centers. Those with increased fall risk received individualized OEP home exercises and were advised to return for monthly follow-up visits. Three physical performance measures-Timed Up and Go test (TUG), Four-Stage Balance Test (4SBT), and chair rise test (CRT)-and the Activities-specific Balance Confidence scale (ABC) were assessed at the initial visit (IV) and each follow-up visit. Two groups were created to distinguish participants who returned for their second follow-up (F2) visit within 3 months from those who returned between 3 and 6 months. Within-group change from IV to F2 was calculated using repeated-measures t tests. Repeated-measures 2-way analyses of variance were used to test for main and interaction effects of group and visit.

Results and discussion: One hundred thirty CHAMP participants aged 76.1 (SD = 8.1) years demonstrated statistically and clinically significant improvements in the 3 physical performance measures (mean 4SBT: IV 29.5 seconds, F2 31.5 second, P = .001), (mean TUG: IV 12.7 seconds, F2 11.9 seconds, P = .021), (mean CRT: IV 0.258 stands/second, F2 0.290 stands/second, P = .002), but not in balance confidence (mean ABC: IV 62.2, F2 64.4, P = .154). A significant interaction of group by visit for the TUG was observed, suggesting that better TUG performance was associated with quicker return for follow-up.

Conclusions: Results indicated that program participants improved from IV to F2 in measures related to fall risk.

Background and purpose: Older adults at risk for falls live independently in the community in their own home and have rehabilitation needs. However, little is known about whether home coaching of older adults can decrease falls at home. We sought to determine whether a novel program for preventing falls and a loss of exercise capacity, the T4H program, in which home helpers act as exercise coaches by using an information technology (IT) device, was acceptable and feasible.

Methods: Between February 2015 and October 2015, we performed a cluster randomized controlled trial in which home helpers either assisted older adults 75 years and over, to participate in the T4H program, or provided standard home help over 3 months. We assessed levels of acceptability and satisfaction among the older adults and home helpers with regard to the exercise program and the technologies used. To measure efficacy, the main outcome measures for the older adults were the absence of falls requiring medical or paramedical care, unplanned hospitalizations, walking ability in a Timed Up and Go test (TUG), and self-care ability by the Barthel Index at the 3-month follow-up visit.

Results and discussion: Overall, 35 older adults were included, aged 89 years and with 68.6% women. Eighty-five percent of the respondents were pleased or very pleased to have participated in the T4H exercise program, 70% were satisfied with the IT devices, and 92% were satisfied with their home helper's level of involvement. Two of the 4 home helper respondents were satisfied or very satisfied with the exercise program, and 2 were moderately satisfied. The proportions of older adult participants with no falls or no unplanned hospitalizations were higher in the T4H group (92.3% and 85.7%, respectively) than in the control group (81.8% and 71.4%, respectively), although these intergroup differences were not statistically significant. The T4H and control groups did not differ significantly with regard to the TUG time (median [IQR]: 27.6 seconds [17.9-58.6] vs 30.7 seconds [19.7-57.2], respectively) or the Barthel Index (median [IQR]: 90 [75-95] and 90 [75-95], respectively).

Conclusions: The novel T4H home help model was feasible and was associated with a high level of participant satisfaction. We observed a trend toward fewer falls and hospitalizations and better quality of life in the older adults.
