目标：通过分析质心（COM）运动和能量恢复，深入了解痉挛性双瘫儿童步态模式的机械效率低下。设计：前瞻性研究，采用组间测量分析脑瘫儿童（CP）和年龄匹配的无CP对照儿童之间的差异。设置：在步态实验室进行评估。参与者：15名患有痉挛性双瘫的儿童和6名年龄匹配的无CP的对照组，平均年龄为9.7岁。干预措施：不适用。主要结果指标：评估的步态数据包括时间-距离因素、COM垂直偏移、COM上所做的工作，结果：脑瘫患儿的能量回收率比对照组低33%（P
Objective: To gain insight into the mechanical inefficiencies of gait patterns used by children with spastic diplegia by analysis of center of mass (COM) movement and energy recovery.Design: Prospective study using between-group measures to analyze differences between children with cerebral palsy (CP) and age-matched controls without CP.Setting: Assessments were performed in a gait laboratory.Participants: Fifteen children with spastic diplegia and 6 age-matched controls without CP with a mean age of 9.7 years.Interventions: Not applicable.Main Outcome Measures: Gait data assessed included temporal-distance factors, COM vertical excursion, work done on the COM, and the percentage of energy transferred and relative phase between the potential and kinetic energy.Results: Children with CP had a 33% smaller energy recovery factor than the controls (P
