title: Gait analysis of spinal cord injured subjects: effects of injury level and spasticity.
abstract: OBJECTIVE
  To identify abnormalities in the gait of spinal cord injured (SCI) subjects, particularly in relation to injury level and spasticity.
  
  
  METHODS
  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.
  
  
  METHODS
  Spinal cord injury clinic of a tertiary care hospital.
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  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.
