Cohorts and Interventions

Group / Cohort
Patients with symptomatic lumbar spinal stenosis; 30-meter walking task (15 meters round trip) following by a rest period of 2 minutes. Participants are invited to perform the 30-meter walking task twice. Inertial sensors are put on each participant foot.
Healthy elderly; 30-meter walking task (15 meters round trip) following by a rest period of 2 minutes. Participants are invited to perform the 30-meter walking task twice. Inertial sensors are put on each participant foot.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
biomechanical walking parameters (gait cycle, stride length, walking time, walking speed, swing width, minimal toe clearance)	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)	During the 30-meter walking test
Quality of life (Euro-Qol - 5D)	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.	One time (before the completion of the 30-meter walking test)
International Physical Activity Questionnaire (IPAQ)	Physical activity habits. IPAQ score range from 1 to 3 where a score of 3 indicates a higher practice of physical activity	One time (before the completion of the 30-meter walking test)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
French-Canadian adaptation of Swiss Spinal Stenosis Questionnaires (FC-SSSQ)	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.	One time (before the completion of the 30-meter walking test) - Only for patients with lumbar spinal stenosis
