title: The immediate effect of treadmill walking on step variability in boys with a history of severe traumatic brain injury and typically-developed controls.
abstract: OBJECTIVE
  To examine the immediate effect of treadmill walking (i.e. enforced walking at a fixed gait velocity) on gait variability among children post-severe traumatic brain injury (TBI) and typically-developing (TD) age-matched controls.
  
  
  METHODS
  Twelve boys post-severe TBI and 18 TD boys participated in this study. Ages were 7-13 years. Step time and length variability were assessed by an electronic walkway prior to and after treadmill walking for 6 minutes.
  
  
  RESULTS
  Significantly reduced walking velocity and step length, with significantly increased step length variability were noted among children post-TBI compared to the TD subjects when walking on level ground prior to the treadmill. Treadmill walking reduced step length variability in TD children, while there was a slight increase in variability in children post-TBI (p < 0.05).
  
  
  CONCLUSIONS
  Walking on a treadmill at a fixed gait velocity has a different effect on boys post-severe TBI and TD controls.
