Participants will be categorized into two categories: "workers," patients on temporary work leave due to low back pain, and "non-workers," patients unable to work due to this condition after exhausting all available therapeutic solutions. Monitoring period (30 physiotherapy sessions): evaluations will be conducted at sessions 1, 15 and 30, on the two groups. Evaluation session 3 months after the end of the physiotherapy sessions.
