What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Walking taskOther
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: 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.
Measured: 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
Measured: Baseline, 6 weeks post-surgery, 6 months post-surgery
Change from baseline Walking time
Time participants take to do the walking task in seconds
Measured: 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
Measured: Baseline, 6 weeks post-surgery
Change from baseline Gait cycle
Gait cycle (% stance phase, % swing phase)
Measured: Baseline, 6 weeks post-surgery
Change from baseline Stride length
Stride Length [m] describes the distance between two successive footprints on the ground, from the heel of a foot to the heel of the same foot, one cycle after.
Measured: Baseline, 6 weeks post-surgery
Secondary outcomes (2)
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.
Measured: Baseline, 6 weeks post-surgery
Change from baseline Minimal To Clearance
Min. Toe Clearance (meter) is the minimum height of the toes during swing phase.
Measured: Baseline, 6 weeks post-surgery

Questions about this trial
What is this clinical trial studying?
An observational study of Lumbar Spinal Stenosis, run by Université du Québec à Trois-Rivières at 1 site in Canada.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 11 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change from baseline French-Canadian adaptation of Swiss Spinal Stenosis Questionnaires (FC-SSSQ) (time frame: Baseline, 6 weeks post-surgery, 6 months post-surgery). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 May 2026.
