Efficacy of game training combined with surface electromyography biofeedback on post-stroke dysphagia.

Objective: To explore the efficacy of game training combined with surface electromyography biofeedback (sEMG-BF) in the treatment of dysphagia after early stroke.
Methods: Ninety patients with early post-stroke dysphagia (PSD), who were diagnosed and treated from March 2021 to December 2022, were divided randomly into a control group (30 cases), experimental group 1 (30 cases) and experimental group 2 (30 cases). The control group received routine swallowing rehabilitation and transcranial direct current stimulation. Experimental group 1 received sEMG-BF in conjunction with the care provided to the control group. Experimental group 2 received sEMG-BF and game training in addition to the care provided to the control group. Before and after treatment, all three patient groups were evaluated using the WADA water swallowing test, the Functional Oral Intake Scale (FOIS), sEMG and a tongue manometer test.
Results: Before treatment, there was no significant difference (P > 0.05) among the three groups of patients in terms of WADA water swallowing rating, FOIS score, submandibular muscle sEMG peak, swallowing time limit and maximum tongue pressure. After treatment, all three groups exhibited improvements in these indices compared with those before treatment (P < 0.05). Experimental group 1 showed greater improvement than the control group (P < 0.05), and experimental group 2 exhibited greater improvement than experimental group 1 and the control group (P < 0.05).
Conclusion: Game training combined with sEMG-BF can significantly improve the swallowing function of patients with PSD.
