To date, an important challenge that clinicians hare facing in the assessment and diagnosis of intermittent claudication is that pathologies associated with vascular or neurogenic claudication can coexist in the same patient. Differentiation between both origins can be difficult due to variable signs and symptoms which can be atypical.

The first aim of this study was to elaborate and validate a treadmill walking test that would help discriminate between neurogenic claudication from vascular claudication. The second objective of this study is to determine if the treadmill walking test can d...
