To study the clinical efficacy of acupuncture combined with external washing of Chinese medicine in treating children with spastic cerebral palsy. Methods:A random number table was used to divide 173 children suffered from spastic cerebral palsy into two groups. Patients in the control group received conventional cerebral palsy rehabilitation therapies, and the treatment group gave patients extra acupuncture treatment and external washing of Tonifying Liver and Benefiting Kidney Formula apart from the same therapies as the control group. After three treatment courses (30 days as a course), the changes in muscle tone and gross motor development were compared between the two groups. Results:At the end of the third course, there were significant differences between the treatment group and control group in changes of muscle tone and gross motor development (P<0.01); the total effective rate in treatment group was 94.1%, which also showed significant differences compared with the 83.8% effective rate in control group (P<0.01). Conclusion: Acupuncture combined with external washing of traditional Chinese medicine can effectively reduce muscle tension in children with spastic cerebral palsy, and promote the development of the movement, so as to effectively improve children’s living skills, and reduce the burden on the family.
