NCT03633578

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

EXPERIMENTAL

Patients are asked to walk ont a treadmill in four conditions: with and without distraction (virtual environment) and at different speed (comfortable vs high).

Behavioral: walk test

Interventions

walk testBEHAVIORAL

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

Interventional group
