After being informed about the study and potential risks, all patients who meet the inclusion criteria, after signing the informed consent, will be randamized divided into two groups in a blind manner. The patients will undergo a 3-week treatment (6 days per week and 1 day for rest, a total of 18 days of treatment). Those in the control group are treated with conventional flexor-extensor alternating electrical acupiont stimulation, and in the treatment group, programmed stimulation will be adopted (30 minutes, once a day). Besides, data from healthy participants will be collected and processed for reference and control purposes.
The purpose of this study is to study the effect mechanism of programmed flexor-extensor alternating electrical acupiont stimulation on upper limb functional reconstruction after stroke.
