The biomechanical Nature of nucleus Pulposus in a fissured disc revealed by quantitative MRI performed under dynamic conditions
Résumé
Physiotherapy is a health care discipline based on movement assessment and treatment. Mechanical Diagnosis and Therapy (MDT) is a reliable and efficient approach using repeated end-range movements to reverse symptoms among patients presenting with musculoskeletal disorders (May et al. 2018). The rationale behind this approach in regard to low back pain is based on the dynamic nature of the pathological intervertebral disc biomechanics. When the Annulus Fibrosus (AF) is centrifugally fissured (radial fissure), the Nucleus Pulposus (NP) could spread into the fissure under patient movement influence. For example, an extension movement can push the NP into an anterior fissure and increase patient pain while a flexion movement would purge the fissure of the NP and reduce patient pain.
