To synthesise the best available evidence for the effectiveness of interventions delivered in community-based rehabilitation (CBR) centers on physical fitness, for community-dwelling older adults living in Asian countries. This study is a systematic review and meta-analysis. Seven English and two Chinese electronic databases were searched for randomised controlled trials (RCTs) and quasi-experimental studies that were conducted by centers providing CBR. Independent reviewers screened, quality-appraised and extracted data. The primary outcome was physical fitness measured by validated assessment tools, including the Timed Up and Go Test (TUG), gait speed, hand grip strength, Functional Reach Test (FRT), and one-leg standing test. Assessments of activity of daily living and quality of life using tools including the Barthel Index, Short Form (SF)-12, and SF-36 were secondary outcomes. After screening 5,272 studies, 29 studies were included (16 RCTs, 13 quasi-experimental studies) from four countries. Meta-analyses found that CBR programs significantly decreased TUG time (mean difference [MD], -1.89 seconds; 95% confidence interval [95% CI], -2.84 to -0.94; I2=0%; Z=3.90, p<0.0001), improved gait speed (MD, 0.10 m/s; 95% CI, 0.01–0.18; I2=0%; Z=2.26, p=0.02), and increased one-leg standing time (MD, 2.81 seconds; 95% CI, 0.41–5.22; I2=0%; Z=2.29, p=0.02). Handgrip strength and FRT showed no statistically significant improvement in the meta-analyses. CBR may improve aspects of physical fitness for older adults in Asian countries. However, variability in intervention components and measurement tools reduced the ability to pool individual studies. Further trials are required with robust designs including standardised measures of physical fitness.
