Nine subjects (12 sides) with cerebral palsy who walked in equnius were evaluated prior to and 1 year after surgical tendo Achilles lengthening. Gastrocnemius and soleus length [Gait Posture, 6 (1997) 9] and plantarflexor force [Gait Posture, 6 (1997) 9; J Biomech, 23 (1990) 495] were calculated. The length of the gastrocnemius and soleus increased significantly (P<0.01) following the intervention. Force output of the triceps surae during push-off increased significantly (13.95 N/kg body weight (BW) preop to 30.31 N/kg BW postop; P<0.01). Assessment of the force-length capacity of the triceps surae in candidates for tendo Achilles lengthenings may identify individuals at risk of residual weakness and iatrogenic crouch.
对9名患有脑瘫且行走时呈马蹄内翻足的受试者（12侧）在跟腱延长手术前及术后1年进行了评估。计算了腓肠肌和比目鱼肌的长度[《步态姿势》，6（1997年）9]以及跖屈肌力量[《步态姿势》，6（1997年）9；《生物力学杂志》，23（1990年）495]。干预后，腓肠肌和比目鱼肌的长度显著增加（P<0.01）。蹬离期腓肠肌三头肌的力量输出显著增加（术前为13.95 N/kg体重（BW），术后为30.31 N/kg BW；P<0.01）。对跟腱延长术候选者的腓肠肌三头肌力量-长度能力进行评估，可能有助于识别存在残留无力和医源性蹲伏风险的个体。
