Study population: The patients will be recruited within the pain unit of the General Hospital of Valenciennes, within the framework of the multidisciplinary consultation of the optimized pain and dedicated to the low back pain patients, where intervene a neurosurgeon algologist and a podiatrist posturologist.

The selection of patients enrolled in the multidisciplinary pain consultation dedicated to low back pain patients will be reviewed by the Clinical Study Technician (screening) and checked by the principal investigator before the newsletter is sent.

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.


Eligibility criteria: Inclusion Criteria:

* Suffering from low back pain, possibly associated with painful gluteal radiation in the form of mono or bilateral pygalgia (non-radicular) evolving for at least three months (chronic low back pain
* Understanding and being able to express himself in French

Primary outcomes:
measure: Correlation between the average speed of displacement of the center of pressure measured in the open-eyes position and the level of pain felt in patients suffering from chronic low back pain
timeFrame: Baseline
Secondary outcomes:
measure: Correlation between the other stabilometric parameters (mean surface, mean frontal and sagittal position) of postural stability measured in the open-eyes position and the level of pain felt.
timeFrame: Baseline
measure: Correlation between the stabilometric parameters (mean speed, mean surface, mean frontal and sagittal position) of postural stability (measured in the open-eyes position and in the closed-eyes position) and neuropathic pain
timeFrame: Baseline
measure: Correlation of stabilometric parameters (mean speed, mean surface, mean frontal and sagittal position) of postural stability (measured in open-eyes and closed-eyes position) with the degree of kinesiophobia and quality of life.
timeFrame: Baseline
measure: Reproducibility of the stabilometric measurements (average speed, average surface, average frontal and sagittal position) in each of the conditions (in the open-eyes position and in the closed-eyes position).
