This study compared the temporal-distance (TD) gait values of two groups of neurologically impaired subjects with published TD gait values of healthy subjects and analyzed the influence of nine clinical characteristics on TD values in the neurologically impaired subjects. Velocity, cadence, step length, stride length, and ratio of stride length to lower extremity length were recorded for 37 subjects with hemiparesis and 24 subjects with multiple sclerosis. Temporal-distance values were well below normal values, even in functionally independent subjects. Overall, the subjects with hemiparesis had lower values than the subjects with multiple sclerosis. Of the nine characteristics examined, only diagnosis, etiologic factor (for hemiparesis), type of ambulation aid, and functional category were related significantly to TD values. Our findings suggest that TD gait performance goals for patients with neurological impairment should be based on values from impaired rather than healthy subjects and that these goals should be adjusted for the individual patient's diagnosis, etiologic factor, type of ambulation aid, and functional category.
本研究将两组神经功能受损受试者的时间-距离（TD）步态值与已发表的健康受试者的TD步态值进行了比较，并分析了九种临床特征对神经功能受损受试者TD值的影响。记录了37例偏瘫患者和24例多发性硬化症患者的速度、步频、步长、步幅以及步幅与下肢长度的比值。即使是功能独立的受试者，其时间-距离值也远低于正常值。总体而言，偏瘫患者的值低于多发性硬化症患者。在所检查的九种特征中，只有诊断、病因（针对偏瘫）、行走辅助器具类型和功能类别与TD值显著相关。我们的研究结果表明，神经功能受损患者的TD步态表现目标应基于受损受试者而非健康受试者的值，并且这些目标应根据个体患者的诊断、病因、行走辅助器具类型和功能类别进行调整。
