RESUMO
Objective To observe the effect of electroacupuncture at extensors plus acupoints based on syndrome differentiation on the wrist-ankle activity in post-stroke hemiplegia. Method A total of 168 patients with post-stroke hemiplegia were randomly divided into a control group and a treatment group, 84 cases each. Both groups were prescribed with Western medication, based on which, the control group received electroacupuncture at acupoints based on syndrome differentiation, and the treatment group received electroacupuncture at extensors plus acupoints based on syndrome differentiation. The changes of electromyography (EMG) in the two groups after the intervention were observed, and the clinical efficacies were compared between the two groups.Results The total effective rate was 95.1% in the treatment group versus 91.0% in the control group, and the between-group difference was statistically significant (P0.05), but the intra-group differences were statistically significant in both groups(P0.05).Conclusion Electroacupuncture at extensors plus acupoints based on syndrome differentiation can increase the motor unit of carpi radialis and decrease the spasm of gastrocnemius in post-stroke hemiplegia, and consequently produce a remarkable clinical efficacy.
