Multiple parameters of gait were evaluated in 50 adult acquired hemiplegic patients and 30 control patients with no history of gait abnormality and no deviation from normal gait by observational analysis. Findings in the hemiplegic group include: 1) increase in the proportion of the gait cycle spent in stance and double-limb support phases in both the normal and affected limb; 2) consistent deviation from normal gait pattern by observation and objective pattern analysis; 3) abnormal phasic activity of specific muscles and muscle groups in the affected limb; and 4) a consistent electrogoniometric deviation from normal joint ankle progression in the affected hip, knee and ankle. These data lend credence to the hypothesis that gait deviation in adult acquired hemiplegia follows a consistent pattern varying with the severity of central nervous system involvement. These data also provide a baseline from which to measure therapeutic intervention in this complex patient population.
通过观察分析，对50名成年后天性偏瘫患者和30名无步态异常病史且步态无偏离正常情况的对照患者的多个步态参数进行了评估。偏瘫组的研究结果包括：1）正常肢体和患侧肢体在站立期和双下肢支撑期所花费的步态周期比例增加；2）通过观察和客观模式分析发现与正常步态模式存在持续偏差；3）患侧肢体特定肌肉和肌肉群的阶段性活动异常；4）患侧髋、膝和踝关节的关节角度测量与正常关节踝关节进展存在持续偏差。这些数据支持了这样一种假设，即成年后天性偏瘫的步态偏差遵循一种随中枢神经系统受累严重程度而变化的一致模式。这些数据还提供了一个基线，可据此衡量对这一复杂患者群体的治疗干预效果。
