This study systematically reviews the effects of muscle strength exer-cises on muscle mass and strength in stroke patients by analyzing ran-domized controlled trials. Ten studies, involving a total of 378 stroke pa-tients, were included in the meta-analysis. The standardized mean dif-ference (SMD) and confidence intervals (CIs) were calculated using a random effects model. The results indicated that strength exercises had a medium effect on increasing muscle strength in stroke patients (SMD, 0.6; 95% CI, 0.47–0.72; I2=51%; P<0.05). Specifically, strength ex-ercises were found to be particularly effective in chronic stroke pa-tients, showing a medium effect on muscle strength (SMD, 0.68; 95% CI, 0.55–0.81; I2=45%; P<0.05). The study also compared the effects based on repetition maximum (RM) settings, revealing that strength increased significantly regardless of whether RM was used, with studies showing medium effects (with RM: SMD, 0.52; 95% CI, 0.4–0.64; I2=0%; P<0.05; without RM: SMD, 0.65; 95% CI, 0.4–0.91; I2=72%; P<0.05). The study concludes that strength exercises are beneficial for improving muscle strength in chronic stroke patients, but the use of RM to set exercise in-tensity is not strictly necessary.
