Contribution of the Podiatrist-Posturologist in the Evaluation of the Link Between the Stabilometric Parameters and the Pain Felt in Patients With Chronic Low Back Pain

Study Overview
=================
Brief Summary
-----------------
Chronic low back pain is one of the major causes of disability worldwide. Knowledge about the pathophysiology of low back pain is insufficient, and an accurate diagnosis can only be obtained in 10 to 15% of cases. The absence of a precise diagnosis leads to a therapeutic challenge due to the large number of treatments available, the overall efficacy of which is low to moderate. Therefore, the identification of subgroups of non-specific chronic low back pain patients is essential and will allow the optimization of therapeutic management. A detailed description of the stabilometric parameters associated with the evaluation of pain, kinematic disturbance and the degree of kinesiophobia would allow us to establish specific postural profiles, to propose a relevant clinical model and to improve the accuracy of the diagnosis of people with chronic low back pain. The objectives of this research project are to evaluate the relationship between stabilometric parameters and pain (main objective), lumbar kinematics, kinesiophobia, and quality of life (secondary objectives) in order to propose specific postural profiles in chronic low back pain patients.
