Electroacupuncture of Scalp Motor Area to Improve Post-Stroke Wrist Dyskinesia
Condition: Stroke Sequelae; Movement Disorders
MeSH terms: Stroke; Dyskinesias; Movement Disorders
Study type: Interventional

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.

Intervention description(s): 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.; 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.
