Sciatic Nerve Stiffness Using Two-Sequences of Lower Limb Neurodynamic Testing: A Shear Wave Elastography Study
The purposes of the study are: 1. To measure differences in Sciatic nerve (SN) stiffness using shear-wave elastography (SWE) during two movement sequences of the lower limb neurodynamic test (LLNT) in low back pain with sciatica. 2. To measure differences in Sciatic nerve stiffness using shear-wave elastography during two movement sequences of the lower limb neurodynamic test in control group. 3. To compare difference in Sciatic nerve stiffness using shear-wave elastography during two movement sequences of the lower limb neurodynamic test between low back pain patients with sciatica and control group.
• Thirty participants ranging in age from 25 to 40 years from both genders with a diagnosis of low back pain with radiating leg pain and thirty control group.
• The main symptoms are low back pain with unilateral leg pain(sciatica) for 3-12 months for group A.
• Patients with lumbar disc herniation (L4-5) with diagnostic imaging as MRI for group A.
• Positive straight leg raising are considered for inclusion in the study for group A.
• Control group must be free from any symptoms of nerve irritation or compression, with normal neurological examination findings, including reflexes, sensation, negative straight leg raising and motor strength.
