Objective: To observe the clinical effect of transcutaneous acupoint electrical stimulation (TEAS) on patients with limb dysfunction after cerebral infarction.

Methods: Eighty-seven patients with limb dysfunction after cerebral infarction were divided into the control group and the treatment group at a ratio of 1:1 according to the random number table method. Both groups received conventional treatment. The control group received percutaneous acupoint sham stimulation, and the treatment group received percutaneous acupoint electrical stimulation therapy. Stimulation treatment was performed for 4 weeks. The improvement rate of neurological deficit score of the patients’ limb function was observed as the main clinical outcome, and the changes in simplified Fugl-Meyer Assessment (FMA) score and the modified Barthel Index (MBI) score were evaluated as the secondary clinical outcomes.

Results: Compared with the control group, the clinical effective rate of the treatment group was 88.89%, and the difference was statistically significant (P<0.05); as compared with the control group, the treatment group could significantly improve the simplified FMA and modified MBI scores, and the neurological damage was significantly improved (P<0.05).

Conclusion: TEAS can significantly improve the limb function of patients with cerebral infarction to a certain extent, improve the ability of daily life of patients, and improve the quality of life of patients. It is worthy of further clinical application.
