      摘要 目的：通过分析痉挛型脑瘫儿童进行不同舞蹈治疗动作时下肢肌群共收缩指数，筛选更适合痉挛型脑瘫儿童训练非优势侧的关节稳定性动作，为舞蹈治疗小组剧目编排时的动作分配提供研究依据。 方法：使用Delsys无线表面肌电系统采集痉挛型脑瘫儿童和健康儿童在进行Plié、Battement tendu、Relevé动作时非优势侧股直肌、半腱肌、胫骨前肌、腓肠肌内侧头的表面肌电信号。通过股直肌和半腱肌、胫骨前肌和腓肠肌内侧头的积分肌电分别计算这两对肌肉的共收缩指数。 结果：①进行Plié舞蹈动作时，痉挛型脑瘫儿童组（CP组）与健康儿童组（TD组）股直肌和半腱肌的肌肉共收缩指数比较有显著性差异（t=2.597，P=0.014），其中CP组高于TD组；②进行Battement tendu舞蹈动作时，CP组与TD组股直肌和半腱肌、胫骨前肌和腓肠肌内侧头的肌肉共收缩指数比较均无显著性差异；③进行Relevé舞蹈动作时，CP组与TD组胫骨前肌和腓肠肌内侧头的肌肉共收缩指数比较有显著性差异（Z=﹣2.594，P=0.009），其中CP组高于TD组。 结论：在Plié、Battement tendu、Relevé三种舞蹈动作中，Battement tendu更适合痉挛型脑瘫儿童训练。

Abstract:

      Abstract Objective： To analyze the co-contraction indexes of lower limb muscle groups during ballet functional movements in spastic cerebral palsy（CP） children，in order to identify movements more suitable for training lower limb joint stability in the non-dominant leg，thereby providing a reference for movement assignment in dance movement therapy. Method： The surface electromyogram of the non-dominant leg muscles-specifically the rectus femoris， semitendinosus， tibialis anterior and medial head of gastrocnemius- were recorded using the Delsys Trigno surface EMG system during Plié， Battement tendu， and Relevé. The co-contraction indexes of thighs and shanks were calculated based on their integrated electromyography. Result： ①During Plié， there was a statistically significant difference in the co-contraction index of rectus femoris and semitendinosus between the CP group and typically developing (TD) group（t=2.597， P=0.014）， with the CP group exhibiting a higher co-contraction index； ②During Battement tendu， there was no statistically significant difference in the co-contraction indexes of two muscle groups between CP group and TD group； ③During Relevé， there was a statistically significant difference in the co-contraction index of tibialis anterior and medial head of gastrocnemius between CP group and TD group （Z=﹣2.594， P=0.009）， with the CP group showing a higher CI. Conclusion： Among the three ballet-based movements assessed (Plié, Battement tendu, and Relevé), Battement tendu was more suitable for training in CP children.
