Brief Summary
Motor control, notably expressed through the complexity of the variability of the locomotor pattern, is disturbed at the central level by an apprehension of pain and movement, more than pain itself (or by biomechanical / structural damage of the spine) in chronic low back pain (cLBP) patients. The aim of this study is to control that variability is reduced during gait at comfortable level and to test that distraction can reduce pain avoidance and therefore increase variability in cLBP patients.

Study Arms (1)
Interventional group
EXPERIMENTALPatients are asked to walk ont a treadmill in four conditions: with and without distraction (virtual environment) and at different speed (comfortable vs high).
Interventions
The patient will have to walk on a treadmill in four different conditions: * without distraction at preferential speed * with distraction at preferential speed * without distraction at the speed of 130% of the preferential speed * with distraction at the speed of 130% of the preferential speed
Eligibility Criteria
You may qualify if:
- The patient must have his informed consent and signed the consent form.
- The patient must be affiliated or beneficiary of a health insurance plan
- The patient is at least 18 years old and under 75 years old
- Patients with common chronic low back pain for more than 6 months
You may not qualify if:
- The subject participates in another interventional study
- The subject is under the protection of justice, guardianship or curatorship
- The subject refuses to sign the consent
- It is impossible to inform the subject
- Chronic symptomatic low back pain (tumoral pathology, infectious, or progressive inflammatory)
- Unable to walk for more than 10 minutes (during interrogation)
- Lower limb pain (EVA lower limb (s) ≥ Lumbar EVA)
