目的：探讨踝足矫形器(AFO)对位和足板长度对中风后偏瘫患者膝关节矢状面运动学和动力学的影响。设计：重复测量，准实验研究。地点：运动分析实验室。研究对象：16例中风后偏瘫患者和12例同龄健康成人志愿者。干预：偏瘫患者在4种情况下进行步行测量：(1)不穿AFO(只穿鞋)；(2)关节AFO足底屈曲90度止动和全长足板对齐AFO(CAFO)；(3)在鞋跟高度补偿式AFO(HHCAFO)中，相同的AFO与胫骨垂直对齐；(4)相同的AFO(胫骨垂直)，长度为3/4的脚板-3/4 AFO。主要观察指标：矢状面踝关节和膝关节的运动学和运动学。结果：成人偏瘫患者的步行速度不受不同条件的影响(P=.095)。与无AFO组相比，所有AFO组在初始接触时和摆动中期的足底屈曲度均有所降低(P
Objective: To investigate the effect of ankle-foot orthosis (AFO) alignment and foot-plate length on sagittal plane knee kinematics and kinetics during gait in adults with poststroke hemiplegia.Design: Repeated measures, quasi-experimental study.Setting: Motion analysis laboratory.Participants: Volunteer sample of adults with poststroke hemiplegia (n= 16) and able-bodied adults (n= 12) of similar age.Interventions: Subjects with hemiplegia were measured walking with standardized footwear in 4 conditions: (1) no AFO (shoes only); (2) articulated AFO with 90 degrees plantar flexion stop and full-length foot-plate-conventionally aligned AFO (CAFO); (3) the same AFO realigned with the tibia vertical in the shoe-heel-height compensated AFO (HHCAFO); and (4) the same AFO (tibia vertical) with 3/4 length foot-plate-3/4 AFO. Gait of able-bodied control subjects was measured on a single occasion to provide a normal reference.Main Outcome Measures: Sagittal plane ankle and knee kinematics and kinetics.Results: In adults with hemiplegia, walking speed was unaffected by the different conditions (P=.095). Compared with the no AFO condition, all AFOs decreased plantar flexion at initial contact and mid-swing (P
