Impact of Pelvic Asymmetry on Hip Joint Proprioception

In this study, participants with confirmed lumbar radiculopathy will undergo clinical and biomechanical assessment. Pelvic alignment will be assessed in both the frontal plane and the sagittal plane using Kinovea software for image-based angle measurements. Hip joint proprioception will be evaluated using an isokinetic dynamometer to assess joint position sense (JPS) under controlled conditions. Additionally, the Numerical Pain Rating Scale (NPRS) will be used to quantify subjective pain levels.

The goal is to identify whether a correlation exists between pelvic asymmetry and deficits in hip joint proprioception and low back pain in this patient group. The findings may contribute to improving targeted rehabilitation strategies and clinical decision-making in the management of patients with lumbar radiculopathy.
