Dysphagia, or swallowing disorder, is a common complication following stroke, significantly impacting patients' quality of life. Electromyographic biofeedback (EMGBF) therapy has emerged as a potential rehabilitation technique to improve swallowing function, but its efficacy in comparison with conventional treatments remains to be further explored.
To investigate the effects of different treatment intensities of EMGBF on swallo
The participants were divided into three groups, all of which received routine neurological drug therapy and motor function rehabilitation training. On the basis of routine swallowing disorder training, the EMGBF group received additional EMGBF training, while the enhanced EMGBF group received two additional training sessions. Four weeks before and after treatment, the degree of swallo
Initially, there was no significant difference in VGF and PAS scores among the groups (P > 0.05). After four weeks, all groups showed significant improvement in both VGF scores and PAS scores. Furthermore, the standardized swallowing assessment and videofluoroscopic dysphagia scale scores also improved significantly post-treatment, indicating enhanced swallowing function and motor function of the hyoid-bone laryngeal complex, particularly in the intensive EMGBF group.
EMGBF training is more effective than traditional swallowing training in improving swallowing function and the movement rate of the hyoid laryngeal complex in patients with post-stroke dysphagia.
Core Tip: This study evaluates the efficacy of electromyographic biofeedback (EMGBF) training in improving swallowing function in patients with post-stroke dysphagia. It differentiates between conventional rehabilitation, standard EMGBF, and intensive EMGBF protocols, focusing on their impact on swallowing mechanics and the hyoid-bone laryngeal complex movement. Results indicate that intensive EMGBF significantly enhances swallowing function, suggesting its superiority over conventional methods. This highlights EMGBF's potential as a beneficial clinical tool for post-stroke dysphagia rehabilitation, warranting its broader adoption and further investigation into its long-term effects and mechanisms.
