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

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.

Treatment and study plan

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.

Primary outcomes

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

    Time frame: 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.

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

    Time frame: 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.

  3. Change from baseline International Physical Activity Questionnaire (IPAQ)

    Time frame: 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

  4. Change from baseline Walking time

    Time frame: Baseline, 6 weeks post-surgery

    Time participants take to do the walking task in seconds

  5. Change from baseline Walking speed

    Time frame: Baseline, 6 weeks post-surgery

    the walking stride velocity (meter/second) is the mean speed of forward walking, calculated in meters per second

  6. Change from baseline Gait cycle

    Time frame: Baseline, 6 weeks post-surgery

    Gait cycle (% stance phase, % swing phase)

  7. Change from baseline Stride length

    Time frame: 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.

Secondary outcomes

  1. Change from baseline Swing Width

    Time frame: 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.

  2. Change from baseline Minimal To Clearance

    Time frame: Baseline, 6 weeks post-surgery

    Min. Toe Clearance (meter) is the minimum height of the toes during swing phase.
