Methods In 286 cases of spasmodic CP, 7 kinds of Chinese massage were adopted, named massage on acupoints to promote circulation of the Governor Vessel, massage for strengthening the spleen and benefiting qi, spine-pinching therapy, segmental massage, foot massage, massage for promoting the recovery of muscle strength and massage for promoting ROM of joints. Chinese massage was applied in musical background. Buddha music and five-element music of Chinese medicine (music of the Heart, Liver and Kidney Meridians) were optioned. The treatment was given once or twice a day and 30 days made one course. The angles of femoral adductor and dorsal flexion of foot as well as the score of composite spasticity scale (CSS) were observed before and after treatment so that the therapeutic effect was assessed. Results In 30 days of treatment, 106 cases (37. 1%) were effective markedly, 172 cases (60. 1%) effective and 8 cases (2.8%) failed. The angle of dorsal flexion of foot was (105.64± 12.66)° and (76.58± 9.89)° before and after treatment respectively; the angle of femoral adductor was (119.89±25.47)° and (158.99± 18.66)° before and after treatment respectively; the score of CSS was (12.39±2.56) and (7. 069 ± 2.97) before and after treatment respectivel, there was significant difference before and after treatment (all P〈0.01). Conclusion Chinese massage for promoting the Governor Vessel, benefiting the kidney and strengthening the spleen combined with music therapy brings the extremely active effect into play on the recovery of sitting, kneeling, standing and walking for children with CP.展开更多
