Biomechanical Parameters of Gait in Patients With Symptomatic Lumbar Spinal Stenosis and Healthy Elderly.

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to compare biomechanical walking parameters between patients with symptomatic lumbar spinal stenosis and healthy elderly.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Patients with symptomatic lumbar spinal stenosis<br>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<br>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 |
