Correlation Between Motor Control Dysfunction and Radiographic Parameter in Non Specific Chronic Low Back Pain

Participants will be assessed for lumbar motor control using a pressure biofeedback unit (PBU) during the Abdominal Draw-In Maneuver (ADIM) in both crock lying and prone positions. This is a non-invasive test to evaluate deep core muscle function (TrA and MF) in patients with NSCLBP. No therapeutic intervention will be administered.
