Aging reduces the accuracy of self-reported walking limitation in patients with vascular-type claudication
Journal of Vascular Surgery, 06/15/2012
Abraham P et al. – Prediction of treadmill walking capacity from the WIQ score should account for age. The TransAtlantic Inter–Society Consensus suggests that self–reported limitation has an equal weight as measured walking distance in the treatment choices and follow–up of patients with peripheral arterial disease. The WIQ should probably be used with caution in clinical routine, and constant–load treadmill testing is probably not the ideal candidate in elderly patients. New or adapted tools are likely needed in such patients but remain to be studied.
