| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Walking task | Other | 30 meters walking task (15 meters round trip) following by a rest period of 2 minutes. Participants are invited to perform the 30 meters walking task twice. Inertial sensors are put on each participant foot. |
| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline 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. | Baseline, 6 weeks post-surgery, 6 months post-surgery |
| Change from baseline Quality of life (EuroQol - 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. | Baseline, 6 weeks post-surgery, 6 months post-surgery |
| Change from baseline 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 | Baseline, 6 weeks post-surgery, 6 months post-surgery |
| Change from baseline Walking time | Time participants take to do the walking task in seconds | Baseline, 6 weeks post-surgery |
| Change from baseline Walking speed | the walking stride velocity (meter/second) is the mean speed of forward walking, calculated in meters per second | Baseline, 6 weeks post-surgery |
| Change from baseline Gait cycle | Gait cycle (% stance phase, % swing phase) |
| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline Swing Width | Swing Width (m) is the maximal lateral excursion of the foot during swing phase. It is the maximum lateral distance between the forward path and the real path of the foot. | Baseline, 6 weeks post-surgery |
| Change from baseline Minimal To Clearance |
