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. DESIGN: Nonrandomized case control study performed in a teaching university hospital outpatient setting. PATIENTS: The sample of convenience involved male patients with lower extremity claudication (n = 19) and 11 healthy men of similar ages. INTERVENTIONS: Subjects were asked to walk at self-selected speed for 20 meters on a level, indoor surface. OUTCOME MEASURES: 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. CONCLUSION: 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.
