title: Gait characteristics of patients with claudication.
abstract: OBJECTIVE
  Intermittent claudication of the lower extremity vessels produces pain during walking. This study differentiates walking patterns of patients with claudication from walking patterns of healthy individuals.
  
  
  METHODS
  Nonrandomized case control study performed in a teaching university hospital outpatient setting.
  
  
  METHODS
  The sample of convenience involved male patients with lower extremity claudication (n = 19) and 11 healthy men of similar ages.
  
  
  METHODS
  Subjects were asked to walk at self-selected speed for 20 meters on a level, indoor surface.
  
  
  METHODS
  Walking velocity and number of steps were averaged over each of five trials, and step length was calculated from these measures.
  
  
  RESULTS
  Patients with claudication walked slower and had decreased step length and decreased cadence compared with controls (p < .001). No positive relationship was found between disease severity, peak walking time, and step length, cadence, or speed.
  
  
  CONCLUSIONS
  All patients with claudication, regardless of disease severity, demonstrated abnormal gait parameters compared with controls. Further studies should evaluate whether the abnormal gait parameters significantly curtail walking ability.
