Two standard treadmill walking tests were carried out 1 wk apart upon 117 patients with stable claudication. [The patients had different sites of arterial occlusion.] Although total walking time achieved was reproducible, there was a highly significant delay in the onset of pain during the 2nd test. Absolute limb pressures, determined by Doppler ultrasound, were reproducible for the group as a whole, although individual variation could be significant. A single walking test is an inadequate assessment of claudication.
