Objective To assess the impact of resistance training on the rehabilitation treatment effects in stroke patients with sarcopenia.Methods Forty-four patients with stroke and sarcopenia admitted to the hospital from September 2023 to March 2024 were selected as the subjects of the study.Based on the principle of intergroup balance and comparability,they were randomly divided into a control group and an observation group using a random number table method,with 22 cases in each group.Both groups of patients received standard comprehensive rehabilitation training for stroke,while the observation group added resistance training for a 4-week intervention.Before and after the intervention,the limb skeletal muscle mass[appendicular skeletal muscle mass index(ASMI)]and the ability of daily living activities[modified Barthel index(MBI)]of two groups were compared.Results Before the intervention,there was no statistically significant difference in ASMI between the two groups(P>0.05).After the intervention,the ASMI levels of both groups improved,but it was higher in the observation group than in the control group(P<0.05).Before the intervention,there was no statistically significant difference in MBI between the two groups(P>0.05).After the intervention,the MBI scores of both groups increased,but it was higher in the observation group than in the control group(P<0.05).Conclusion Resistance training can effectively improve the limb skeletal muscle mass and daily living activity ability of stroke patients with sarcopenia.
