Summary

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.

Detailed description

Participants will be randomly divided into an electroacupuncture group and a manual acupuncture group according to a ratio of 1: 1. In the manual acupuncture group, participants will be needled in the scalp motor area on the lesion side and left in place for 30 minutes after obtaining qi. During needle retention, the needles will be intermittently twisted for 2min twice, with a frequency of about 200 r/min. The same acupoint was selected as the manual acupuncture group in the electroacupuncture group. After obtaining qi, electroacupuncture stimulation will be applied using a continuous wave at a frequency of 2 Hz. The stimulation intensity will be adjusted based on the patient's tolerance, and each treatment will be lasted for 30 minutes. Participants patients in both groups will be treated once a day and rest for one day after six consecutive days of treatment, for a total of three weeks.

Type	Name	Description
OTHER	manual acupuncture	In manual acupuncture, the scalp motor area on the lesion side will be needled and left in place for 30 minutes after obtaining qi. During the needle retention, the needles will be twisted intermittently for 2 minutes twice, at a frequency of approximately 200 r/min.
OTHER	electroacupuncture	In electroacupuncture, the scalp motor area will be needled, and after obtaining qi, the treatment will involve applying electroacupuncture stimulation using a continuous wave with a frequency of 2 Hz. The intensity of the stimulation will be adjusted based on the patient's tolerance, and each treatment session will last for 30 minutes.
