Chair-stand exercise improves post-stroke dysphagia

Area of Science:

• Geriatric medicine
• Neurology
• Rehabilitation science

Background:

• Stroke is a leading cause of disability, often resulting in dysphagia (swallowing difficulties).
• Conventional rehabilitation may not fully address dysphagia and functional deficits in post-stroke patients.
• Whole-body exercises, like chair-stands, are increasingly explored for their therapeutic potential.

Purpose of the Study:

• To investigate the impact of whole-body chair-stand exercises on clinical outcomes in stroke patients with dysphagia undergoing rehabilitation.
• To determine if the frequency of chair-stand exercise is associated with improvements in swallowing, motor function, and hospital stay duration.

Main Methods:

• Retrospective cohort study of 148 stroke patients with dysphagia (Food Intake Level Scale [FILS] <7) from 2016-2018.
• Patients performed chair-stand exercises in addition to standard rehabilitation.
• Multivariate analyses assessed the association between exercise frequency and outcomes like FILS score, dysphagia presence, Functional Independence Measure-motor (FIM-motor) score, and length of stay.

Main Results:

• Higher frequency of chair-stand exercise was independently associated with better FILS scores and reduced odds of dysphagia at discharge.
• Exercise frequency positively correlated with FIM-motor scores and their gains, indicating improved motor function.
• Increased chair-stand exercise frequency significantly reduced the length of hospital stay.

Conclusions:

• Chair-stand exercise is a beneficial addition to conventional rehabilitation for stroke patients with dysphagia.
• Incorporating whole-body exercises can lead to improved swallowing function, enhanced activities of daily living, and shorter hospitalizations.
• This suggests that rehabilitation programs for post-stroke dysphagia should integrate whole-body exercise components.
