Low Back Pain (LBP) is one of the common causes of morbidity worldwide, with a one-month prevalence of 23.3 %. Number of people with LBP reached 577 million people in 2020. LBP has been the leading cause of years lived with disability from 1990 to 2017. The highest incidence of LBP is in people in their third decade of age. LBP is a complex disease difficult to treat as most of these cases (80 - 90 %) are classified as non-specific meaning that the pain cannot be attributed to any specific injury or pathology.
Until now exercise therapy is commonly used as the treatment of choice in the revalidation program of LBP. The aim of physical treatment is to improve function and prevent disability from getting worse.
LumbaCure® is a robotic system driven by a proprietary movement algorithm to induce a specific and controlled mobilization of the hips and the low back in patient requiring treatment by physical exercises due to orthopedic disorder, especially low back pain.
The investigation include an intervention period of 4 weeks The main objective is to compare the impact on disability (Oswestry disability Index) and movement performance of the interventions (LumbaCure® vs physical exercises supervised by the physiotherapist) in two parallel groups of patients suffering from chronic low back pain.
The investigation includes an intervention period of 4 weeks and a follow-up period of 6 months (post intervention period).

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Test Intervention arm | Experimental | The LumbaCure® is a robotic system which provide active, specific and controlled mobilization of the low back. The device is to be used by the Physiotherapist at the rehabilitation centre. The duration of a session for the patient is 15 minutes. Patients follow a serie of 12 consecutive LumbaCure® sessions at a frequency of 3 sessions / week for 4 weeks. |
|
| Control Intervention arm | Active Comparator | A set of core stability exercises/active qualitative mobilization has been defined with principal investigator according to the standard of care at Investigator site. At each session, 5 exercises will be selected by the investigator depending on the evolution and pathology of the patient. Five minutes of warm-up will be performed before starting the exercises session. The program will last 15 to 30 min depending on the time required for the patient to complete the prescribed exercises. Patients follow a serie of 12 consecutive physical exercises sessions at a frequency of 3 sessions / week for 4 weeks. |
