To identify abnormalities in the gait of spinal cord injured (SCI) subjects, particularly in relation to injury level and spasticity.
Case-control study comparing the gait of SCI individuals with matched controls. Video-motion analysis was used to collect data on temporal and kinematic variables. Spasticity was assessed using the Ashworth score and pendulum test. Data regarding age, height, weight, mechanism, and level of injury were also collected.
Spinal cord injury clinic of a tertiary care hospital.
Twenty-seven SCI individuals volunteered to participate in the study. All had retained walking ability (Frankel D) and could ambulate independently for a minimum of 10m with or without walking aids. Individuals with cauda equina injuries were excluded from the study. Age, gender, etiology of injury, and interval since injury were not used as exclusion criteria. Ten age-, sex-, and anthropomorphically matched controls were also recruited.
Subjects with thoracic injures demonstrated reduced cadence, forward velocity, and knee angular velocity, whereas lumbar injuries resulted in reduced stride length and ankle velocities. These differences were statistically significant (p < .05). Gait in individuals with cervical injuries was not significantly different.
Kinematic gait analysis is a sensitive means of quantifying gait abnormalities. Spasticity and injury level determine the pattern of abnormality in gait after spinal cord injury.
确定脊髓损伤（SCI）患者步态中的异常情况，尤其是与损伤水平和痉挛的关系。
病例对照研究，比较脊髓损伤个体与匹配对照组的步态。采用视频运动分析收集时间和运动学变量的数据。使用Ashworth评分和摆锤试验评估痉挛情况。还收集了有关年龄、身高、体重、损伤机制和损伤水平的数据。
一家三级护理医院的脊髓损伤诊所。
27名脊髓损伤个体自愿参与研究。所有患者均保留行走能力（Frankel D级），并能在有或无辅助器具的情况下独立行走至少10米。马尾神经损伤患者被排除在研究之外。年龄、性别、损伤病因和受伤后的时间间隔不作为排除标准。还招募了10名年龄、性别和人体测量学匹配的对照组。
胸段损伤的患者步频、前进速度和膝关节角速度降低，而腰段损伤导致步幅长度和踝关节速度降低。这些差异具有统计学意义（p < 0.05）。颈段损伤患者的步态无显著差异。
运动学步态分析是量化步态异常的一种敏感方法。痉挛和损伤水平决定了脊髓损伤后步态异常的模式。
