总结：探讨腓肠肌筋膜延长术对脑瘫患者踝关节步态运动学和动力学的影响。本回顾性研究纳入了20名独立的步行者（24侧）。评估包括临床检查、关节运动学和动力学计算以及步态期间表面肌电图（EMG）的收集。术后观察到静态足跟活动度（ROM）改善，站立和摆动背屈增加。动力学分析表明，在踝关节周围产生的异常能量在中期的立场和一个统计学上显着的增加，在后期的立场推离产生的能量减少。
Summary: The effect of surgical lengthening of the gastrocnemius fascia on ankle joint kinematics and kinetics during gait in patients with cerebral palsy (CP) was evaluated. Twenty independent ambulators (24 sides) were included in this retrospective study. The evaluation included clinical examination, calculation of joint kinematics and kinetics, and collection of surface electromyography (EMG) during gait. Postoperative improvements were noted in static heelcord range of motion (ROM), with an associated increase in dorsiflexion in stance and swing. Kinetic analysis showed a decrease in the abnormal energy generated around the ankle in midstance and a statistically significant increase in the energy generated in late stance for push-off.
