Observation on the effects of myoelectricity-induced neuromuscular electrical stimulation on muscle surface electromyography and gait spatiotemporal parameters in patients with hemiplegia due to cerebral infarction
Objective To explore the effects of myoelectricity-induced neuromuscular electrical stimulation(NMES)on muscle surface electromyography(sEMG)and gait spatiotemporal parameters in patients with cerebral infarction and hemiplegia.Methods A total of 270 patients with cerebral infarction and hemiplegia admitted to our hospital were enrolled between October 2020 and October 2022.The patients were divided into a myoelectricity-induced NMES group and a NMES group by using random number table method,135 in each group.The changes in sEMG,gross motor function scale(GMFM)scores,daily living activity index(BI),and gait spatiotemporal parameters of the two groups were detected and analyzed.Results After 6 weeks of treatment,sEMG values of tibialis anterior muscle,biceps and gastrocnemius in the myoelectricity-induced group were significantly greater than those in the NMES group(P＜0.05).The scores of GMFM and BI in the myoelectricity-induced group were significantly higher than those in the NMES group(P＜0.05).After 6 weeks of treatment,gait cycle,feet support time and stride width were significantly decreased in both groups(P＜0.05),while stride frequency,walking speed,step length,stride length,support time of affected side and healthy side were sig-nificantly increased(P＜0.05).The gait cycle,feet support time and stride width in the myoelectricity-induced group were significantly lower than those in the NMES group(P＜0.05),while support time of affected side,stride frequency,walking speed,step length and stride length were significantly higher(P＜0.05).Conclusions The myoelectricity-induced NMES can significantly improve the gait of patients with cerebral infarction and hemiplegia,promote the recovery of neurological function,and improve the quality of life of the patients.
