Abstract:
Objective:To evaluate respiratory muscle function before and after respiratory function training using surface electromyography(sEMG)in stroke patients with hemiplegia during recovery period.Method:Forty stroke patients with hemiplegia in the recovery phase were randomly divided into an observa-tion group and a control group,with 20 patients in each group.The control group was given routine rehabilita-tion treatment,while the observation group was given routine rehabilitation treatment combined with respirato-ry function training.Root Mean Square value(RMS)of respiratory muscle surface electromyography,pulmo-nary function indicators such as forced vital capacity(FVC),the forced expiratory volume in 1 second(FEV1),peak expiratory flow rate(PEF),and Fugl-Meyer Motor Scale(FMMS),Berg Balance Scale(BBS)were evaluated before and after 4 weeks of treatment in both groups.Result:After 4 weeks of treatment,the RMS of bilateral sternocleidomastoid muscles,parasternal external in-tercostal muscles,and diaphragmatic muscles,pulmonary function indicators including FVC,FEV1,PEF,FMMS and BBS in both groups were significantly improved(P＜0.05),and the scores of all indicators in the observation group were higher than those in the control group(P＜0.05).The correlation analysis showed that there was a certain correlation between the RMS of respiration muscles and indicators of pulmonary function,FMMS,BBS respectively in two groups after treatment(P＜0.05);the correlation between the RMS of respira-tion muscles and indicators of pulmonary function,FMMS,BBS in the observation group(r＞0.5,P＜0.05)was higher than that in the control group(r＜0.5,P＜0.05).Conclusion:Respiratory function training can significantly improve pulmonary function in stroke patients with hemiplegia during recovery period.Surface electromyography can be used to evaluate the respiratory muscle contraction function in stroke patients with hemiplegia.
