The purpose of this study is to test and validate a new questionnaire in order to get a "walking estimated limitation calculated by history (WELCH) in patients referred for vascular investigations.
Two questionnaires the WELCH and the "walking impairment questionnaire" (WIQ) are submitted to patients referred for vascular investigations for suspêcted peripheral arterial disease (PAD). Comparison of score to hemodynamic parameters (first goal) or maximal walking distance (MWD) on treadmill (secondary goal). Scoring of the WIQ is performed according to references. Scoring of the WELCH has been submitted for copyright protection (involves a series of 4 additions a subtraction and a single multiplication)

| Correlation with treadmill result |
Analysis of first inclusion only in patients that are included multiple times over the study period.Calculation of questionnaires score from predetermined methods and analysis of the coefficient of determination and coefficient of correlation to maximal walking distance on treadmill, in the subgroup of patients that have a routine treadmill scheduled during the visit. |
| 1 day |
| Facility of the scoring of the questionnaires | Proportion of WELCH scores calculated by physician and comparison to the proportion of WIQ score calculated by physicians as a estimation of the facility to calculate the score by mental calculation in routine | 1 day |
| Reliability of the questionnaire | Comparison of the scores of the WELCH in the patients that may be seens within 3 weeks of their first inclusion, for any reasons, (e.i. seen first for a doppler and two weeks later for a treadmill test)over the study period. Analysis of the reliability through the coefficient of variation of the score. | 3 weeks |
| sensitivity of the WELCH to changes | Comparison of the scores of the WELCH in the patients that may be seens within 1 year from their first inclusion, for any reasons, (e.i. seen follow up of their disease)over the study period. Analysis of the changes of the score to changes of the ABI. Analysis of the changes of the score to changes in maximal walking distance if available. | 1 year |
