Brief summary

This observational study aims to investigate the impact of pelvic asymmetry on hip joint proprioception in patients with lumbar radiculopathy. Proprioception, or the body's sense of joint position and movement, plays an essential role in posture and stability. People with lumbar radiculopathy often suffer from back and leg pain and may experience changes in posture and balance. This study aims to examine the relationship between pelvic asymmetry, hip joint proprioception and low back pain which may help improve physical therapy approaches for such patients.

Detailed description

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.

Design outcomes

Primary

Measure	Time frame	Description
Hip Joint Position Error (JPE)	Baseline	Hip joint position sense (JPS) will be assessed using an isokinetic dynamometer. Participants will perform three consecutive trials to replicate the target joint angle, and the average absolute repositioning error will be calculated for analysis.

Secondary

Measure	Time frame	Description
Pain Intensity	Baseline	Assessment of low back pain via numerical pain rating scale (NPRS)
