Methods： Sixty children with cerebral palsy were randomly divided into an acupuncture group （Group Acup.） and an acupuncture plus music group （Group Acup.＋ M）. Simple acupuncture was applied in Group Acup., and acupuncture at 5 groups of points plus music were applied in Group Acup. ＋M., The treatment was given once every two days with 3 treatments weekly, and 36 treatments constituted a therapeutic course. Therapeutic effects including movement improvement were observed for comparison after 3 courses of treatments. Results： The comprehensive functions were elevated in both groups, and the total effective rate in Group Acup. ＋ M was obviously better than that in Group Acup （P〈0.05）. Movement functions were also improved in both groups, but the differences in improvement of creeping and kneeling, standing, and walking were significant between the two groups （P〈0.01）, showing the effect in Group Acup. ＋ M was better than that in Group Acup.. Conclusion： The therapy of acupuncture plus music gained better therapeutic effect on cerebral palsy than simple acupuncture, which provided new thoughts for treating the disease by comprehensive therapies.展开更多
