Can initial sarcopenia affect poststroke rehabilitation outcome?

This study investigated the association between the presence of sarcopenia, measured by nonhemiplegic grip strength, and the level of functional recovery, measured by the modified Rankin Scale (mRS) at six months after stroke. We performed a retrospective cohort analysis of a prospectively maintained database of 194 hemiplegic poststroke patients, who had been admitted to the Department of Rehabilitation Medicine of a university-affiliated hospital. At 6 months after stroke, 72.2% of patients had mRS score>3, with more women (81.0% vs. 66.0%, p = 0.024) showing poor recovery. Both men (51.3% vs. 35.9%, p = 0.041) and women (42.2% vs. 6.7%, p = 0.022) with mRS score>3 had a higher rate of sarcopenia. Univariate analysis revealed that the presence of sarcopenia was associated with a 2.71-fold higher risk of poor recovery at six months. In addition, women had a 2.18-fold higher risk of poor outcome. Multivariable logistic regression analysis revealed that the presence of sarcopenia was associated with poor functional outcome (odds ratio [OR] = 2.61, 95% confidence interval [CI]: 1.14–5.98, p = 0.024) in men, but this association was notably stronger in women (OR = 9.93, 95% CI: 1.22–81.19, p = 0.032). This study suggests that the presence of sarcopenia two weeks after stroke may increase the risk of poor functional outcome six months after stroke. Most notably, women with sarcopenia within 2 weeks from stroke onset were more significantly like...
