NCT04381663

Brief Summary

The study will consist of two parts:

  • In Study A, objectively assessed physical activity, gait, balance, range of movement of specific joints during walking and neurophysiological findings between patients with cervical spine stenosis (CSS) without myelopathy who will be treated conservatively and patients with stenosis and signs of myelopathy who are candidates for surgical Treatment will be compared.
  • In Study B, the 6-month changes in the same outcomes in patients treated conservatively (from the first specialist consultation until 6 months later) and in patients treated surgically (preoperative day and 6-month post-operatively) will be quantified.

Outcome Measures

Primary Outcomes (3)

  • Difference in gait symmetry

    The subjects will perform an instrumented gait analysis on an overground walkway with two embedded force plates

    approximate duration: 30 minutes. Assessment will be performed at visit 1 and will be repeated 6 months after study inclusion at visit 2

  • Change in balance performance

    Balance performance will be assessed using the modified clinical test of sensory integration of balance (m-CTSIB) using the Biodex Balance System SD

    approximate duration: 30 minutes. Assessment will be performed at visit 1 and will be repeated 6 months after study inclusion at visit 2.

  • Difference in neurophysiological outcome

    Quantitative score of Motor evoked potentials (MEP) and Somato-sensory evoked potentials (SEP)

    approximate duration: 30 minutes. Assessment will be performed at visit 1 and will be repeated 6 months after study inclusion at visit 2.

Secondary Outcomes (10)

  • Difference in daily physical activity

    monitored for 7 consecutive days at visit 1 or 1 week before surgery and 6 months later at visit 2

  • Difference in spinal cord gray and white matter areas

    approximate duration of the scan: 30. Assessment will be performed at visit 1 and will be repeated 6 months after study inclusion at visit 2 (Measurement at visit 2 only in patients with cervical spine stenosis treated conservatively).

  • Change in segmental quantitative muscle strength

    approximate duration: 10 minutes. Assessment will be performed at visit 1 and will be repeated 6 months after study inclusion at visit 2.

  • Change in 25-foot walk test

    approximate duration: 3 minutes. Assessment will be performed at visit 1 and will be repeated 6 months after study inclusion at visit 2.

  • Change in 6-minute walk test

    approximate duration: 6 minutes. Assessment will be performed at visit 1 and will be repeated 6 months after study inclusion at visit 2.

  • +5 more secondary outcomes
