Correlation Between Hip Mobility and Thoracic Flexion in Patients With Non-Specific Low Back Pain

Correlation Between Hip Mobility and Thoracic Flexion in Patients With Non-Specific Low Back Pain

This cross-sectional observational study investigates the relationship between hip joint mobility and thoracic flexion in patients diagnosed with non-specific low back pain. Altered hip range of motion may influence spinal mechanics and contribute to thoracolumbar dysfunction. The study aims to determine whether a significant correlation exists between hip mobility and thoracic flexion in adults with chronic non-specific low back pain.

Non-specific low back pain is a common musculoskeletal condition associated with altered movement patterns and compensatory biomechanical adaptations. Restricted hip mobility may alter lumbo-pelvic rhythm and influence thoracic spine motion during functional activities.

This cross-sectional observational study included 60 adults aged 18 to 45 years diagnosed with non-specific low back pain lasting more than three months. Participants underwent assessment of hip range of motion using a universal goniometer and thoracic flexion mobility using a Spinal Mouse device.

Hip flexion, extension, internal rotation, and external rotation were measured bilaterally. Thoracic flexion mobility was recorded in degrees using the Spinal Mouse system during forward trunk flexion.

Correlation analysis was performed to determine the association between hip mobility parameters and thoracic flexion range. No therapeutic intervention was administered, and all measurements were conducted during a single assessment session.
