Evaluation of the implementation and effectiveness of a community-based brain-computer interface cognitive group training in healthy community-dwelling older adults: A randomized controlled implementation study (Preprint)

BACKGROUND Cognitive training can improve cognition in healthy older adults OBJECTIVE The objectives are to evaluate the implementation of a community-based computerized cognitive training (CCT) and its effectiveness on cognition, gait, and balance in healthy older adults. METHODS A single-blind randomized controlled trial with baseline and follow-up assessments was conducted in two community centers (CCs) in Singapore. A total of 94 healthy community-dwelling adults aged 55 and above participated in a ten-week CCT program with two-hour instructor-led group classes conducted twice a week. Participants used a mobile application to play games targeting attention, memory, decision making, visuospatial abilities, and cognitive flexibility. Implementation was assessed at the participant-, provider-, and community-level (e.g., reach, implementation, and facilitators & barriers). Effectiveness measures were the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), Color Trails Test Part 2 (CTT2), Berg Balance Scale, and GAITRite® walkway measures (single & dual task gait speed, dual task cost, and single & dual task gait variability index (GVI)). RESULTS The data was based on Intention-to-treat (ITT) and Per-protocol (PP) analysis. In the ITT group, single task GVI increased (b = 2.32, P = .02, 95% CI [0.30, 4.35]) and RBANS List Recognition subtest deteriorated (b = -0.57, P = .01, 95% CI [-1.00, -0.14]) in both groups. In the PP group, time taken to complete CCT2 (b = -13.5, P = .01, 95% CI [-23.95, -3.14]) was faster in the intervention group. Single task gait speed was also marginally significantly maintained in the intervention group (b = 5.38, P = .063, 95% CI [-0.30, 11.36]) but declined in the control group. For RBANS subtests, Picture Naming (b = 0.43, P = .04, 95% CI [0.01, 0.85]) improved significantly in both groups while List Recognition subtests (b = -0.54, P = .02, 95% CI [-1.00, -0.08]) performance deteriorated. CONCLUSIONS CCT can be successfully implemented in community settings to improve attention, executive function, and visuospatial abilities while maintaining gait speed amongst healthy older adults. Findings help to identify suitable healthy ageing programs that can be implemented on a larger scale within communities. CLINICALTRIAL ClinicalTrials.gov Identifier NCT04439591

AbstractTranslation of community-based functional training for older adults to reduce frailty is still lacking. We evaluated the effectiveness and implementation of a community-delivered group-based functional power training (FPT) program for frail older adults within their neighborhoods. A two-arm, multicenter assessor-blind stratified randomized controlled trial was conducted at four local senior activity centers in Singapore. Sixty-one community-dwelling older adults with low handgrip strength were randomized to intervention (IG) or control (CG) group. The IG underwent the FPT program (power and balance exercises using simple equipment) delivered by a community service provider. The 12-week program comprised 2 × 60 min sessions/week. CG continued usual activities at the centers. Functional performance, muscle strength, and frailty status were assessed at baseline and 3 months. Program implementation was evaluated using RE-AIM framework. The program was halted due to Coronavirus Disease 2019-related suspension of senior center activities. Results are reported from four centers, which completed the program. IG showed significantly greater improvement in the Short Physical Performance Battery test as compared to CG (p = 0.047). No effects were found for timed up and go test performance, muscle strength, and frailty status. The community program exhibited good reach, effectiveness, adoption, and implementation. Our study demonstrated that FPT was associated with greater improvement in physical function in pre-frail/frail participants as compared to exercise activities offered at local senior activity centers. It is a feasible intervention that can be successfully implemented for frail older adults in their neighborhoods. Trial registration ClinicalTrials.gov, NCT04438876.

Community Dwelling Older Adults

Background: Physical exercise is suggested to be effective for preventing cognitive decline in older adults, but the relative efficacy of different types of exercise have yet to be clarified. Objective: This single-blinded randomized controlled trial was designed to investigate the differential effects of aerobic exercise training (AT), resistance exercise training (RT), and combined exercise training (CT) on cognition in older adults with subjective memory complaints (SMC). Methods: Community-dwelling older adults with SMC (n = 415; mean age = 72.3 years old) were randomly assigned to one of the four groups: AT, RT, CT, or control group. The study consisted of two phases: a 26-week intervention and a 26-week follow-up. The participants were evaluated at baseline, 26 weeks (postintervention), and 52 weeks (follow-up). The primary outcome of this study was memory function, which was assessed using the Logical Memory II subtest of the Wechsler Memory Scale-Revised (WMS-R) score. The secondary outcomes included global cognitive function, verbal fluency, working memory, processing speed, and executive functions. Results: Intention-to-treat analysis by a mixed-effect model repeated measure showed that the AT group had significantly improved performance on the WMS-R Logical Memory II test (2.74 [1.82–3.66] points) than the control group (1.36 [0.44–2.28] points) at the postintervention assessment (p = 0.037). The effect was more pronounced in those without amnesia than those with amnesia. No significant improvement was observed in the RT and CT groups. Conclusion: This study suggests that AT intervention can improve delayed memory in community-dwelling older adults, particularly in individuals without objective memory decline.
