Assessment of Gait Parameters and Their Impact on Postoperative Recovery in Patients With Lumbar Spinal Stenosis

Change from baseline French-Canadian adaptation of Swiss Spinal Stenosis Questionnaires (FC-SSSQ)

时间窗: Baseline, 6 weeks post-surgery, 6 months post-surgery

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.

Change from baseline Walking time

时间窗: Baseline, 6 weeks post-surgery

Time participants take to do the walking task in seconds

Change from baseline Quality of life (EuroQol - 5D)

时间窗: Baseline, 6 weeks post-surgery, 6 months post-surgery
