Measurement of Spinal Kinematics During Various Movements

Differences in Spinal Kinematics During Various Activities Between Asymptomatic Subjects and Patients With Chronic Low Back Pain

Participants will perform movements while receiving different visual cues. Spinal kinematics will be measured during these movements and compared between asymptomatic and CLBP participants. Participants will come for a unique session.

Inclusion Criteria:

- sufficient French level to understand the instructions for the tests, the information sheet, the consent form.

For CLBP patients:

- diagnosis of non-specific low back pain (pain from lower ribs to gluteal folds) for more than 3 months.

For asymptomatic participants:

• no history of LBP requiring medical attention during the last two years
• no other concomitant pain or condition that could compromise the evaluation of lumbar kinematics.

Exclusion Criteria:

• pregnancy
• skin allergy to tape
• body mass index (BMI) above 32

For patients with CLBP only:

• specific low back pain (such as the presence of infection, rheumatological or neurological diseases, spinal fractures, tumours)
• any known important spinal deformities
• previous back surgery that limits spinal mobility
• high level of pain at the time of experiment that prevents repeated movements (severity and irritability)
• other concomitant pain or condition that could compromise the evaluation of spinal kinematics.
