Impact of increased trunk muscle mass on trunk function and activities of daily living in older individuals with cerebral infarction.
Clinical Nutrition ESPEN 2024 April
BACKGROUND & AIMS: The association between trunk muscle mass or trunk function or trunk muscle strength and activities of daily living (ADLs) has been reported, but no studies have examined the impact of increased trunk muscle mass on trunk function or ADL. This study aimed to determine whether increased trunk muscle mass is associated with trunk function and ADL in older individuals with cerebral infarction during rehabilitation.
METHODS: This retrospective observational study enrolled 158 patients with cerebral infarction aged ≥65 years who were admitted for post-stroke rehabilitation. The trunk muscle mass index (TMI) was calculated at admission and discharge using bioelectrical impedance analysis. Patients were divided into two groups: one with increased TMI (64 participants; 41 %) and the other without TMI increase (94 participants; 59 %). Multiple linear regression analysis was performed with functional assessment for control of trunk (FACT) or functional independence measure (FIM)-motor gain as the objective variable and increased TMI group as the explanatory variable.
RESULTS: We analyzed a total of 158 patients (79.5 ± 7.8 years of age, 51.9 % men). TMI increase was independently associated with FACT gain (coefficient = 1.413, 95 % confidence interval = 0.34-2.49, P = 0.010), but not with FIM-motor gain.
CONCLUSIONS: The results suggest that increased TMI is independently associated with recovery of trunk function. Further prospective studies are needed to elucidate the relationship between increased TMI and ADL.
