OBJECTIVETo explore clinical safety and efficiency of electroacupuncture combined with acupoint-injection of botulinum toxin A for the treatment of muscle spasticity by spinal cord injury.

METHODSThirty-eight patients with muscle spasticity by spinal cord injury were treated from December 2006 to December 2009 including 26 males and 12 females, with an average age of 45.4 years old ranging from 21 to 68 years. The patients were randomly divided into 3 groups according to admission time, 13 patients in group A were treated with electroacupuncture combined with acupoint-injection of botulinum toxin A, and 13 patients in group B were treated with acupoint-injection botulinum toxin A and 12 patients in group C were treated with electroacupuncture. After 6 months these patients were evaluated by improved muscle Ashworth scoring (MAS) and clinical spasticity index (SCI).

RESULTSThirty-eight patients were followed-up at 6 months after the treatment. The result showed that the MAS scores of group A, B, C before treatment were (3.10 +/- 0.14), (3.20 +/- 0.17), (3.10 +/- 0.16) respectively and the CSI scores were (14.10 +/- 0.14), (14.30 +/- 0.11), (14.20 +/- 0.12) respectively; there were no statistical different among the three groups (P > 0.05). After 6 months of treatment, the MAS scores were (1.10 +/- 0.16), (2.10 +/- 0.13), (2.00 +/- 0.14) respectively and the CSI scores were (9.10 +/- 0.11), (12.10 +/- 0.14), (13.10 +/- 0.12) respectively. The MAS scores and CSI scores of group A were better than the other two groups (P < 0.05).

CONCLUSIONThe combination of Chinese hydropower needles and acupoints with BTX-A injection can achieve a comprehensive treatment and reduce pain and improve life quality quickly. The electroacupuncture combined with acupoint-inject botulinum toxin A is a noval safe and effective technique for the treatment of muscle spasticity by spinal cord injury.
