目的：检验步行过程中髋部伸展范围减小（代表髋部紧张的限制性损伤）这一假设是一致的动态发现，（1）随着年龄的增长而发生，（2）在跌倒的老年人中被夸大。设计：使用 3 维光电运动分析系统，我们比较了老年人和老年人在行走期间的全矢状面运动学（下肢关节运动、骨盆运动）数据。 年轻人以及老年跌倒者和不跌倒者之间。还对每个老年人组的舒适步行速度和快速步行速度进行了比较。地点：步态实验室。参与者：23 名健康老年人受试者、16 名跌倒老人（有反复跌倒史的健康老年人受试者）和 30 名健康年轻成人受试者。主要结果测量：所有主要峰值关节角度和骨盆位置值。结果：峰值髋部伸展是步行期间测量的唯一腿部关节参数， 在老年非跌倒者和跌倒者中，两者均显着低于年轻成人受试者，并且与非跌倒者相比，老年跌倒者甚至更低
Objectives: To test the hypothesis that reduced hip extension range during walking, representing a limiting impairment of hip tightness, is a consistent dynamic finding that (1) occurs with increased age and (2) is exaggerated in elderly people who fall.Design: Using a 3-dimensional optoelectronic motion analysis system, we compared full sagittal plane kinematic (lower extremity joint motion, pelvic motion) data during walking between elderly and young adults and between elderly fallers and nonfallers. Comparisons were also performed between comfortable and fast walking speeds within each elderly group.Setting: A gait laboratory.Participants: Twenty-three healthy elderly subjects, 16 elderly fallers (otherwise healthy elderly subjects with a history of recurrent falls), and 30 healthy young adult subjects.Main Outcome Measures: All major peak joint angle and pelvic position values.Results: Peak hip extension was the only leg joint parameter measured during walking that was both significantly lower in elderly nonfallers and fallers than in young adult subjects and was even lower in elderly fallers compared with nonfallers tall p
