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.
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.
Study Type
OBSERVATIONAL
Enrollment
55
Participants will be invited to walk on a treadmill at a speed of 1,2 mph for at most five minutes for both conditions (straight walking posture and inclined walking posture). Each walking posture condition will be followed by a rest time of five minutes in sitting position. Conditions were randomized in each group using a computer-generated sequence.

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
Leg and back Pain (Visual analog scale)
leg and back pain using a 0-10 points scale
Time frame: Before the walking test, through the walking test completion, at 2:30 minutes of rest, at 5 minutes of rest
Walking impairment Questionnaire (WIQ)
WIQdistance subscale score range from 0 to 100%, WIQspeed subscale score range from 0 to 100%, WIQstairs subscale score range from 0 to 100%, WIQ total score combining distance,speed and stairs subscale range from 0 to 100% Higher values indicate better outcome
Time frame: day 1, before the walking test (this is a transversal study)
Tampa Scale of kinesiophobia
Questionnaire, Total score range from 17 to 68, Higher score indicate a worst outcome
Time frame: day 1, before the walking test (this is a transversal study)
Quality of life of participants
EuroQol 5 dimension (EQ-5D), each section (mobility, self-care, usual activities, pain/discomfort and anxiety/depression) has a score ranging from 1 to 3 and higher values indicate a worst outcome
Time frame: day 1, before the walking test (this is a transversal study)
Impact of pain, function and surgery satisfaction
French-Canadian adaptation of the Swiss Spinal Stenosis Questionnaire Pain subscale score range from 7 to 35 with higher values indicate a worst outcome, Function subscale score range from 5 to 20 with higher values indicate a worst outcome, Satisfaction subscale score range from 6 to 24 with higher values indicate a worst outcome. The total score is composed of the three subscales and range from 18 to 79.
