title: Deficit and change in gait velocity during rehabilitation after stroke.
abstract: OBJECTIVE
  To quantify the initial deficit, change, and outcome in gait velocity during inpatient rehabilitation following stroke.
  
  
  METHODS
  The initial deficit on admission to rehabilitation was quantified by comparing 42 stroke patients with 42 controls matched by gender and age. The change in the stroke patients during the next 8 weeks was quantified and gait outcome was compared with functional and normal criteria.
  
  
  METHODS
  Patients were referred from four inpatient rehabilitation centers at the time of admission following a median of 16.5 days in the acute hospital.
  
  
  METHODS
  
  
  
  METHODS
  ability to give informed consent; unilateral first stroke; ability to walk 10 meters.
  
  
  METHODS
  Patients participated in a median of 17.38 hours of individual physical therapy including a median of 6.92 hours of gait training during the 8 weeks.
  
  
  METHODS
  Gait velocity.
  
  
  RESULTS
  Gait velocity was initially 38.6% (26.7m/min SD = 14.9) of the performance of controls and improved to 55.1% (38.1m/min). At outcome only 24% exceeded the 5th percentile of controls (48.1m/min) or the velocity required to cross the typical signalled intersection (46.2m/min). The change was only 26% of the initial deficit. Fifty-five percent of the patients improved beyond the 95% confidence intervals surrounding the error of measuring change. Indices of responsiveness indicated that there was a high signal-to-noise ratio and a robust effect size.
  
  
  CONCLUSIONS
  Gait velocity discriminated the effect of stroke and the change during rehabilitation.
