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.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
