Sciatic Nerve Stiffness Using Two-Sequences of Lower Limb Neurodynamic Testing: A Shear Wave Elastography Study

Condition(s) studied

Investigational drug(s) / intervention(s)

Lower Limb Neurodynamic Test (LLNT) with Shear Wave Elastography: Participants underwent sciatic nerve stiffness assessment using shear wave elastography during two distinct sequences of the lower limb neurodynamic test. Each participant received: Proximal-to-distal sequence: Starting with hip flexion, followed by knee extension, then ankle dorsiflexion with toe extension. Distal-to-proximal sequence: Starting with ankle dorsiflexion and toe extension, followed by knee extension, then hip flexion.

Study summary

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.

Eligibility

Primary outcome measure(s)

• Shear Wave Velocity (SWV) measured in meters per second (m/s) — 20 minutes, During a single assessment session at baseline
  Quantitative measurement of sciatic nerve stiffness during two different movement sequences of the Lower Limb Neurodynamic Test (LLNT). Higher SWV values indicate increased nerve stiffness.
