摘　　要：目的采用表面肌电技术比较生长痛患儿与正常儿童站立、提踵时小腿肌肉肌电活动的差异。方法 32例伴有旋前足的生长痛患儿作为生长痛组,32名正常儿童作为对照组。所有受试者均测试站立与提踵时胫前肌、腓骨长肌、腓肠肌内侧头、胫骨后肌表面肌电信号。结果站立时,生长痛组腓骨长肌均方根值(RMS)较对照组明显增加(P<0.01);提踵时,生长痛组腓肠肌RMS值较对照组降低(P<0.05),胫骨后肌RMS较对照组明显增加(P<0.01)。结论伴有旋前足的生长痛患儿在站立和提踵时小腿肌肉肌电活动会发生相应改变。Objective To compare the differences of electrical activity in calf muscle of children with growing pains from normal children when standing and heel raising. Methods 32 children with growing pains and foot pronation were as growing pains group, and 32 normal children as control group. All the children were measure with surface electromyography（s EMG） of tibialis anterior, peroneus longus,medial gastrocnemius and tibialis posterior when standing and heel raising. Results The root mean square（RMS） of peroneus longus increased significantly in growing pains group when standing（P〈0.01）. The RMS decreased significantly in medial gastrocnemius（P〈0.05）and increased significantly in tibialis posterior（P〈0.01） when heel raising. Conclusion The characteristics of electrical activity in calf muscle is difference from the normal in the growing pains children with foot pronation during standing and heel raising.
