研究概览
简要总结
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.

研究组 & 干预措施
Interventional group
Patients are asked to walk ont a treadmill in four conditions: with and without distraction (virtual environment) and at different speed (comfortable vs high).
干预措施: walk test (Behavioral)
