OBJECTIVE: Evidence regarding the effect of sarcopenic obesity on recovery in stroke patients is scarce in rehabilitation medicine. The aim of this study was to examine the association between changes in muscle strength and functional outcomes in patients with sarcopenic obesity undergoing rehabilitation after stroke. MATERIALS AND METHODS: This study was a retrospective cohort study of stroke patients, consecutively admitted to post-acute rehabilitation wards of a single hospital, of which, only those diagnosed with sarcopenic obesity at admission were included in the final analysis. Bioimpedance analysis was used to measure skeletal muscle mass and body fat mass. Sarcopenic obesity was defined as the presence of both sarcopenia and obesity. Sarcopenia was diagnosed using muscle mass index and handgrip strength. Obesity was diagnosed using body fat percentage (men ≥30%, women ≥35%). The evaluated outcomes were Functional Independence Measure (FIM)-motor score at discharge and its gain. Multiple regression analysis was used to verify whether changes in hand grip strength during hospitalization were associated with functional outcomes. RESULTS: Sixty-two patients (29 men) with a mean age of 78 years, were analyzed. The mean change in the hand grip strength was 3.9 kg. In multiple regression analysis, changes in the hand grip strength were significantly associated with FIM-motor at discharge (β = 0.34, P < 0.01) and FIM-motor gain (β = 0.58, P < 0.01). CONCLUSIONS: Muscle strength gain was associated with improved functional recovery in stroke patients with sarcopenic obesity.
