The purpose of this study was to describe quantitatively the gait patterns of patients with juvenile rheumatoid arthritis (JRA). Thirty children with JRA and 30 healthy children were evaluated using a computerized gait analysis system. Time-distance characteristics and joint angle excursions were studied. The subjects with JRA walked with significantly decreased velocity, cadence, and stride length. We found no significant difference in step width nor in the percentage of time spent in each phase of the gait cycle. The anterior pelvic tilt of subjects with JRA was significantly increased throughout the gait cycle. Hip extension at the end of single-limb stance and ankle plantar flexion during weight release also were significantly decreased for subjects with JRA. No significant difference between the two groups was noted in knee joint excursion. Areas of emphasis for physical therapy of patients with JRA include increasing velocity, cadence, stride length, hip extension, and ankle plantar flexion and decreasing excessive anterior pelvic tilt.
本研究的目的是定量描述青少年类风湿性关节炎（JRA）患者的步态模式。使用计算机化步态分析系统对30名JRA患儿和30名健康儿童进行了评估。研究了时间-距离特征和关节角度偏移。JRA患者行走时速度、步频和步幅显著降低。我们发现步宽以及步态周期各阶段所花费时间的百分比在两组之间没有显著差异。JRA患者在整个步态周期中骨盆前倾显著增加。JRA患者在单腿站立末期的髋关节伸展和负重释放时的踝关节跖屈也显著降低。两组之间在膝关节偏移方面没有显著差异。JRA患者物理治疗的重点领域包括提高速度、步频、步幅、髋关节伸展和踝关节跖屈，以及减少过度的骨盆前倾。
