Design outcomes

Primary

Measure	Time frame	Description
biomechanical walking parameters (gait cycle, stride length, walking time, walking speed, swing width, minimal toe clearance)	During the 30-meter walking test	Gait cycle = % stance phase, % swing phase / Stride length = describes the distance between two successive footprints on the ground / walking time = time to complete the 30-meters walking test in seconds / walking speed = walking stride velocity measured in meter/second / swing width = the maximal lateral excursion of the foot during the swing phase / minimal toe clearance = minimum height of the toes during the swing phase (in meter)
Quality of life (Euro-Qol - 5D)	One time (before the completion of the 30-meter walking test)	Quality of life related to mobility, self-care, usual activities, pain and discomfort, anxiety and depression. Each category has a score ranging from 1 to 3 and higher values indicate a worst outcome.
International Physical Activity Questionnaire (IPAQ)	One time (before the completion of the 30-meter walking test)	Physical activity habits. IPAQ score range from 1 to 3 where a score of 3 indicates a higher practice of physical activity

Secondary

Measure	Time frame	Description
French-Canadian adaptation of Swiss Spinal Stenosis Questionnaires (FC-SSSQ)	One time (before the completion of the 30-meter walking test) - Only for patients with lumbar spinal stenosis	Pain, function and satisfaction related to lumbar spinal stenosis. 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.
