Details and patient eligibility

About

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.

Enrollment: 16 patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers
