Summary
Game-based biofeedback with laryngeal exercises significantly improved swallowing function in stroke patients. This approach enhanced hyoid bone movement, oral intake scores, and increased nasogastric tube removal rates.
Area of Science:
- Neurology
- Rehabilitation Medicine
- Biomedical Engineering
Background:
- Dysphagia is a common complication of stroke, impacting patient quality of life.
- Traditional swallowing therapies include compensatory strategies and motor exercises.
- Biofeedback shows promise for neuromuscular training and swallowing rehabilitation.
Purpose of the Study:
- To assess the effectiveness of game-based biofeedback integrated with laryngeal elevation exercises for post-stroke dysphagia.
- To evaluate its impact on swallowing function and oral intake.
Main Methods:
- A case-control study involving 20 patients with post-stroke dysphagia, matched into a game-based biofeedback group (n=10) and a control group (n=10).
- Both groups received traditional swallowing treatment and laryngeal elevation exercises.
- The experimental group additionally received game-based biofeedback during laryngeal exercises for 16 sessions.
Main Results:
- The game-based biofeedback group showed statistically significant improvements in hyoid bone displacement (P=.002) and Functional Oral Intake Scale (FOIS) scores (P=.004) compared to the control group.
- 80% of patients in the experimental group discontinued nasogastric (NG) tube use, versus 20% in the control group (OR=6.00, P=.009).
Conclusions:
- Laryngeal elevation training augmented with game-based biofeedback is effective for improving swallowing function in post-stroke dysphagia.
- This combined approach enhances hyoid bone displacement, FOIS scores, and facilitates nasogastric tube removal.
