Self-reported estimation of usual walking speed improves the performance of questionnaires estimating walking capacity in patients with vascular-type claudication

Abstract

Correcting the self-reported estimation of walking capacity by a self-reported estimation of usual walking pace significantly improves the correlation of all WIQ subscale scores and of the EACH-Q score with treadmill measurements of capacity. This confirms the interest of speed estimation in patients with peripheral arterial occlusive disease and claudication.

External Validation of the “Walking Estimated Limitation Calculated by History” (WELCH) Questionnaire in Patients with Claudication

“…9 In parallel, we showed that asking the patient what his/ her usual walking pace was allowed correction through a division and multiplication of the score obtained with the EACH-Q (even so, mental calculation of scoring in this version was difficult). 10 Thus, we recently proposed the WELCH, which is based on the first three items of the EACH-Q and uses the usual walking speed item (with answers slightly changed), and, overall, uses an empirical, completely new, and very simple scoring method that can be calculated mentally without need of a computer. 3 The present study is the latest step in this development process.…”

Exercise Transcutaneous Oximetry of the Buttocks ― External Validation With Computed Tomography Angiography ―

“…If patients were not forced to stop within the first 16 min, the speed and grade were progressively increased from minute 16 according to the previously described protocol. 10 This combination of constant load and increasing load protocol allows all patients to reach symptom limitation, whereas most patients stop during the constant load phase. 11 Patients were encouraged to perform at the highest possible speed for the longest time possible (maximum walking distance) and not to stop at pain occurrence.…”

Comparison of two devices for measuring exercise transcutaneous oxygen pressures in patients with claudication

“…At minute 16, if the patient was still able to walk, the speed and grade were progressively increased by steps of 1 minute up to exhaustion or to limitation by symptoms, as previously reported [15]. Roughly one minute increments of this second phase resulted in grade and speed that were comparable to the Bruce protocol values every three minutes [15]. Patients were encouraged orally to perform the highest possible test duration.…”
