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

Recruiting

• Conditions: Lumbar Spinal Stenosis
• Interventions: Other: Walking task

• Registration Number: NCT04250753
• Lead Sponsor: Université du Québec à Trois-Rivières

Brief Summary

The objective is to observe the evolution of walking parameters during the surgery process and find which of all calculated walking parameters represent the best indicators of functional disabilities and postoperative recovery for patient with lumbar spinal stenosis.

Primary Outcome Measures

Name	Time	Method
Change from baseline Quality of life (EuroQol - 5D)	Baseline, 6 weeks post-surgery, 6 months post-surgery	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.
Change from baseline International Physical Activity Questionnaire (IPAQ)	Baseline, 6 weeks post-surgery, 6 months post-surgery	physical activity habits. IPAQ score range from 1 to 3 where a score of 3 indicates a higher practice of physical activity
Change from baseline Stride length	Baseline, 6 weeks post-surgery	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.
Change from baseline Gait cycle	Baseline, 6 weeks post-surgery	Gait cycle (% stance phase, % swing phase)
Change from baseline French-Canadian adaptation of Swiss Spinal Stenosis Questionnaires (FC-SSSQ)	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	Baseline, 6 weeks post-surgery	Time participants take to do the walking task in seconds
Change from baseline Walking speed	Baseline, 6 weeks post-surgery	the walking stride velocity (meter/second) is the mean speed of forward walking, calculated in meters per second

Secondary Outcome Measures

Name	Time	Method
Change from baseline Swing Width	Baseline, 6 weeks post-surgery	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.
Change from baseline Minimal To Clearance	Baseline, 6 weeks post-surgery	Min. Toe Clearance (meter) is the minimum height of the toes during swing phase.
