Influence of Different Ankle Positions on Nerve Conduction Parameters of Deep Peroneal Nerve

BACKGROUND: The deep peroneal nerve arises as a branch of the common peroneal nerve which courses around the neck of the fibula. The motor component of deep peroneal nerve is responsible for innervating the anterior compartment of the lower leg which includes the tibialis anterior, extensor hallucis longus, extensor digitorum longus, and peroneus tertius muscles. Nerve conduction velocity shortly known as "NCV" tests are used determine the speed of the electrical signals moving along a specific peripheral nerve .This will be helpful in localizing the site of entrapment of peripheral nerves and useful for assessing both recovery and prognosis of any injury to peripheral nervesthere are numerous aspects that could influence nerve conduction study. Although changes in joint position have been reported in several studies to affect nerve conduction velocity of peripheral nerves. the effect of changing ankle joint position on deep peroneal NCV has not been repor Purpose This study will investigate the effect of different ankle positions on: 1. Deep peroneal nerve distal motor latency across ankle joint. 2. Deep peroneal nerve sensory onset latency across ankle joint
