NCT03750474

Brief Summary

Chronic low back pain remains a major public health issue. Low back pain is frequently associated with stiffness changes of the lumbar back muscles. The techniques which assess the stiffness of the back muscles are poorly reliable and do not allow the quantification of stiffness changes. Elastography (magnetic resonance imaging and ultrasound) can be used to objectively and non-invasively quantify in vivo tissue elasticity. The aim of the investigator's study is to compare the stiffness in the main lumbar back muscles (i.e. the erector spinae and the multifidus) by using magnetic resonance elastography and shear wave elastography.

Outcome Measures

Primary Outcomes (1)

  • Stiffness mapping and measurement of the shear modulus (m/s) in the multifidus and the erector spinae (1) with magnetic resonance elastography (Aera; 1,5T)

    First, the subjects undergoes a magnetic resonance elastography in decubitus in two postures: at rest and with stretching of back muscles (hip flexion). Then, stiffness will be measurement with sonography in several postures: prone position, upright, bending forward, bending backward.
