Impact of Trunk Versus Skeletal Muscle Mass Gain on Balance Improvement in Patients with Cerebral Infarction

In patients with cerebral infarction, an increase in TMI was associated with greater improvements in balance function during hospitalization. These results suggest a potential role for trunk muscle mass in supporting balance recovery; however, owing to the observational nature of the study, the findings should be interpreted with caution and viewed as hypothesis-generating. In addition, the lack of association in the subgroup analyses underscores the potential influence of confounding factors, such as the amount and content of rehabilitation, and highlights the need for future studies to control for these variables.
