To observe the therapeutic effect of single exercise therapy and electroacupuncture combined with exercise therapy for treatment of brachial plexus injury， and compare the effects of the two different therapies. Methods： Two hundred and eight patients with brachial plexus injury admitted in our hospital from October 2009 to October 2013 were randomly divided into control group (n=103) and treatment group (n=105). The control group gave patients oral administration of Methycobal nerve nutrition and exercise rehabilitation therapy， and the treatment group applied electro acupuncture treatment except from the same therapies as the control group. After three months of treatment， statistical analysis was observed. Results： The total effective rate of control group was 91.27%， and the total effective rate of treatment group was 99.1%. In the aspect of neural function damage recovery， the clinical curative effects of two groups showed statistically significant differences (P<0.05)， and the treatment group showed better results than the control group. Conclusion： The curative effect of electroacupuncture combined with exercise therapy for treatment of brachial plexus injury has definite therapeutic effect， and it is worth the clinical promotion and further research.
