Electroacupuncture of Scalp Motor Area to Improve Post-Stroke Wrist Dyskinesia

The goal of this clinical trial is to compare the clinical efficacy of electroacupuncture and manual acupuncture in stimulating the scalp motor area for treating post-stroke wrist dyskinesia and its influence on the function of wrist movement-related active muscles. The main question it aims to answer is: which method of stimulating the scalp motor area is more effective in the recovery of wrist motor function after stroke? Participants will be given routine Western medicine treatment and acupuncture treatment on the hemiplegic side. In the manual acupuncture group, participants will be needled in the scalp motor area on the lesion side. The same acupoint was selected as the manual acupuncture group in the electroacupuncture group. The score of Chinese Stroke Scale (CSS), the score of the upper limb of the Barthel Index (BI), the active range of motion (AROM) of wrist joint, and the surface electromyography (sEMG) was used to measure the root mean square (RMS) of extensor carpi radialis longus, extensor digitorum, flexor carpi radialis and flexor carpi ulnaris on the hemiplegic side of the patients before and after the 3-week treatment period, respectively compare the clinical efficacy of the two groups.
