Objectives:
The purpose of this study was to evaluate the relationship between changes in skeletal muscle mass and improvements in swallowing function in stroke patients with dysphagia during rehabilitation.
Methods:
The study included 145 patients with a stroke or dysphagia. The two groups were divided into two groups: those with improved skeletal muscle mass index (SMI) at discharge and those without. Clinical data, including SMI, and Mann Assessment of Swallowing Ability (MASA), were collected from the database.
Results:
The increase in MASA was significantly higher in the group with increased SMI than in the group with no increase in SMI. In the multivariate analysis, the duration of rehabilitation and the group with increased SMI were associated with increased MASA.
Conclusion:
SMI gain and the duration of rehabilitation per day were associated with improved swallowing function in patients with stroke.

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
