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

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

This study aims to investigate the relationship between motor control dysfunction (MCD) and radiographic parameters in non-specific chronic low back pain (NSCLBP). Participants will undergo specific clinical motor control tests and lumbar spine X-rays to evaluate the alignment and coordination of spinal and pelvic structures. Understanding this relationship may help improve rehabilitation strategies and reduce pain in affected individuals.

Non-specific chronic low back pain (NSCLBP) is a common musculoskeletal condition associated with impaired neuromuscular coordination and motor control dysfunction (MCD). This study seeks to determine the correlation between MCD and radiographic parameters including pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), and lumbar lordotic angle (LLA).

A total of 64 participants aged 20-40 with NSCLBP will be evaluated at the Faculty of Physical Therapy, Cairo University. Motor control will be assessed using a pressure biofeedback unit in two positions (crock lying and prone) via the Abdominal Draw-in Maneuver (ADIM). Radiographic measurements will be taken using lateral lumbar spine X-rays in standing posture.

The aim is to identify whether poor activation of deep stabilizing muscles (Transverse Abdominus and Multifidus) correlates with abnormal pelvic alignment and altered spinal curvature. Outcomes may support more effective personalized rehabilitation protocols targeting neuromuscular control to improve spine-pelvis function in NSCLBP patients.

Statistical analysis will include Pearson correlation to test for associations between motor control test performance and radiographic angle values.
