Concurrent Measurement of Isokinetic Muscle Strength of the Trunk, Knees, and Ankles in Patients With Lumbar Disc Herniation With Sciatica

Abstract

Besides the lower trunk strength, concurrent lower unilateral knee and ankle plantar flexion but not dorsiflexion strength was demonstrated in the LDH subjects with unilateral sciatica, regardless of its location. As compared to the limbs without sciatica, an additional 14% reduction of knee extension torque at 180°/s was found in the limbs with sciatica in the LDH patients.
