To evaluate the application of acupuncture therapy in patients with foot drop after apoplectic hemiplegia and effects on external electromyography.Methods:A total of 70 patients with foot drop after apoplectic hemiplegia admitted to Beijing Hospital of Traditional Chinese Medicine，Capital Medical University from June 2016 to June 2017 were randomly divided into two groups，with 35 patients in each group.The control group was given western medicine rehabilitation treatment，and the observation group was given acupuncture combined with western medicine rehabilitation treatment.The clinical efficacy，symptom scores，integrating electromyogram (iEMG) and three-dimensional gait spatial parameters were recorded and compared between the two groups.Results:The total effective rate in the observation group (89.58%) was higher than that in the control group (72.92%)，and the difference was statistically significant (P<0.05).After treatment，the clinical symptom scores (Fugl-meyer and Bathel scores) and the iEMG (tibialis anterior，peroneus longus，peroneus brevis，medial head of gastrocnemius，and lateral head of gastrocnemius) in the observation group were higher than those in the control group (P<0.05).The changes of three-dimensional gait spatial parameters in the observation group were more significant than those in the control group (P<0.05).Conclusion:Acupuncture can effectively improve the scores of sports function，and daily life function and iEMG，significantly coordinate and balance the gait，and increase the clinical treatment effect of patients with foot drop after apoplectic hemiplegia.
