Study Overview
Brief Summary
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 discriminate spinal stenosis from low back pain with radiating pain in lower limb.
Detailed Description
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 discriminate spinal stenosis from low back pain with radiating pain in lower limb. 60 participants (20 with spinal stenosis, 20 with peripheral artery disease and 20 with non-specific low back pain) will be recruited. Participants will be invited to walk on a treadmill at a speed of 1,2 mph for a maximum of five minutes for both tasks (straight walking posture and inclined walking posture). Each walking task will be followed by a rest time of five minutes in sitting position. It is hypothesized that walking time difference for the occurrence of pain and for pain relief will be sensitive and specific to pathologies and help to discriminate lumbar spinal stenosis.

Outcomes
Primary Outcomes
Walking time
Time Frame: Time first back or leg pain (vary between participants from 0 secondes to 300 secondes and is determine by the occurence of leg or back pain), Through the walking test completion
Secondary Outcomes
- Leg and back Pain (Visual analog scale)(Before the walking test, through the walking test completion, at 2:30 minutes of rest, at 5 minutes of rest)
- Walking impairment Questionnaire (WIQ)(day 1, before the walking test (this is a transversal study))
- Tampa Scale of kinesiophobia(day 1, before the walking test (this is a transversal study))
- Quality of life of participants(day 1, before the walking test (this is a transversal study))
- Impact of pain, function and surgery satisfaction(day 1, before the walking test (this is a transversal study))
