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.

Conditions

Lumbar Radiculopathy; Pelvic Asymmetry; Hip Joint Proprioception

Keywords

Lumbar Radiculopathy; Pelvic Asymmetry; Hip Joint Proprioception; Low Back Pain

Outcome Measures

Primary Outcomes (1)

• Hip joint proprioception

  Assessment of hip joint proprioception using an isokinetic dynamometer to measure the Absolute Error (AE) of Joint Position Sense (JPS). Participants will be asked to actively reproduce three specific target hip angles (Flexion, Abduction, and Internal Rotation). For each angle, the mean deviation of three consecutive trials (in degrees) from the target position will be recorded. The entire test will be conducted in a single session to evaluate baseline proprioceptive accuracy.

Study Arms (2)

Pelvic Asymmetry Group

Participants in this group are patients diagnosed with lumbar radiculopathy who present with frontal plane and sagittal plane pelvic asymmetry. Pelvic asymmetry is assessed using Kinovea software . Hip joint proprioception will be evaluated using an isokinetic dynamometer. Pain levels will also be recorded using the Numerical Pain Rating Scale (NPRS).

No Pelvic Asymmetry Group

Participants in this group are patients diagnosed with lumbar radiculopathy who do not exhibit measurable pelvic asymmetry by kinovea software in the frontal plane or the sagittal plane . The same assessment procedures will be applied, including hip joint proprioception using an isokinetic dynamometer and pain assessment using the NPRS

• Lumbar radiculopathy presented by sensory manifestations only.
• The duration of the disease was 3 months or more.
• The age ranged from 25 to 45 years old.
• Body Mass Index (BMI) ranging from ( 18.5 to 24.9 kg/m² ) .

You may not qualify if:
