1 Variability and short-term determinants of walking capacity in patients with intermittent claudication  Alexis Le Faucheur, PhD, Bénédicte Noury-Desvaux, PhD, Guillaume Mahé, MD, Thomas Sauvaget, BSc, Jean Louis Saumet, MD, PhD, Georges Leftheriotis, MD, PhD, Pierre Abraham, MD, PhD  Journal of Vascular Surgery  Volume 51, Issue 4, Pages (April 2010) DOI: /j.jvs Copyright © 2010 Society for Vascular Surgery Terms and Conditions

2 Fig 1 Flow diagram of studied patients with peripheral arterial disease (PAD) shows included/excluded patients, subgroups of analyzed participants, and associated computed parameters. ABI, ankle-brachial index; CV, coefficient of variation; GPS, global positioning system; MWD, maximal walking distance; PSD, previous stop duration; WDBS, walking distance between two stops (induced by lower-limb pain).

3 Fig 2 Individual results from the multivariate analysis are shown for the 36 participants with ≥5 NWB. One bar represents one participant, bars are presented in decreasing values of absolute r. PSD, Previous stop duration. The absolute r value is presented for each individual (r is negative for cumulated time) and the explanatory parameter found in the multivariate analysis (specific color or pattern). Facing each bar is the number of walking bouts during the stroll. Note that white bars represent nonsignificant results and that walking speed was never found as an explanatory parameter to WDBS.

4 Fig 3 A typical example of a global positioning system (GPS) recording and computed results are shown for one patient with peripheral arterial disease. CV, Coefficient of variation; MWD, mean walking distance. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2010 Society for Vascular Surgery Terms and Conditions
