NCT03612089

Brief Summary

To delineate the underlying mechanisms that contribute to chronic low back pain, by extending our knowledge on structural characteristics of the lumbar multifidus muscle using ultrasound muscle imaging, and by examining the association of structural features with functional performance, more precisely proprioceptive control.

Outcome Measures

Primary Outcomes (5)

  • Lumbar multifidus muscle volume measured by 3DfUS

    in patients with chronic low back pain

    immediately after inclusion in the study

  • Lumbar multifidus muscle volume measured by MRI

    in patients with chronic low back pain

    immediately after inclusion in the study

  • Cross-sectional area of the lumbar multifidus

    measured by classic 2D-ultrasound in patients with chronic low back pain and healthy controls

    immediately after inclusion in the study

  • Thickness of the lumbar multifidus

    measured by classic 2D-ultrasound in patients with chronic low back pain and healthy controls

    immediately after inclusion in the study

  • Proprioceptive postural control strategies in patients with low back pain with healthy controls

    Mean center-of-pressure displacement in response to soleus muscle and/or multifidus muscle vibration (60 Hz, 0.5 mm) during upright standing on two support surfaces.

    immediately after inclusion in the study
