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.

Effect of transcranial direct current stimulation combined with respiratory training on dysphagia in post-stroke patients.

BACKGROUND: Transcranial direct current stimulation (tDCS) has a considerable advantage in the rehabilitation treatment of dysphagia. OBJECTIVE: The purpose of this study was to explore the effect of tDCS combined with respiratory training on dysphagia in post-stroke patients. METHODS: From December 2017 to January 2019, 64 post-stroke patients who were hospitalized in the Department of Neurology of the Second Hospital of Hebei Medical University were enrolled in this study. They were randomly divided into control and treatment groups (n= 32). Patients in the two groups received routine swallowing rehabilitation training and respiratory training. On this basis, the patients in the treatment group received tDCS. The anode was placed in the movement area of the pharyngeal cortex on the unaffected side of the patients' bodies, and the cathode was placed in the upper orbital orbit on the opposite side. The current intensity was 1.5 mA, 20 min/time, 1 time/d, and 6 d/w. Before and after the treatment, the water swallow text, functional oral intake scale (FOIS), forced vital capacity (FVC) and peak expiratory flow (PEF) were assessed, and the correlation among them was evaluated. RESULTS: There were no differences in all indexes before and after treatment. After treatment, water swallow text, FOIS, FVC and PEF were all better than before treatment, and the clinical efficacy in the treatment group was significantly better than that in the control group. FVC and PEF were positively correlated with water swallow text and FOIS. CONCLUSION: tDCS combined with respiratory training may have a significant therapeutic effect on dysphagia in post-stroke patients.
