Abstract:

Objective To investigate the efficacy of surface electromyography biofeedback combined with respiratory training on post-stroke dysphagia and its impacts on serum neuron specific enolase (NSE) and insulin-like growth factor 1 (IGF-1) in patients. Methods Totally 120 patients with post-stroke dysphagia in our hospital were stochastically assigned into the control group and the combined group, with 60 patients in each group. Both groups were given conventional treatment first, while the control group received respiratory training treatment. The combined group received surface electromyography biofeedback treatment on the top of the control group. The efficacy, serum NSE, central nervous system specific protein (S100β), IGF-1, functional oral intake scale (FOIS) score, standard swallowing function assessment scale (SSA) score, respiratory function, pharyngeal contraction rate and duration of pharyngeal contraction were compared between the two groups. Results After treatment, the total effective rate was higher in the combined group (χ2=4.876, P<0.05). Compared with before treatment, NSE, S100β, SSA score and pharyngeal contraction rate decreased after treatment in both groups, and those were even lower in the combined group (t=5.193, 9.000, 8.976, 10.614, P<0.05). Compared with before treatment, IGF-1, FOIS score, force vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow rate (PEF) and duration of pharyngeal contraction increased after treatment in both groups, with even higher levels in the combined group (t=4.212, 6.220, 3.765, 6.935, 5.020, 4.249, P<0.05). Conclusion Surface electromyography biofeedback combined with respiratory training can improve neuronal damage in patients with dysphagia, enhance swallowing efficiency, reduce serum NSE, S100β levels and pharyngeal retention time, with significant curative effect.
