Detailed explanation-1: -The foot and ankle dorsiflexors include the tibialis anterior, the extensor hallucis longus (EHL), and the extensor digitorum longus (EDL). These muscles help the body clear the foot during swing phase and control plantarflexion of the foot on heel strike.
Detailed explanation-2: -A lesion of the L5 root, lumbar plexus, sciatic nerve, common peroneal, or the deep peroneal nerve can potentially lead to foot drop due to the weakness of the anterior compartment musculature. The presenting symptom is the inability to ambulate as before.
Detailed explanation-3: -The most common cause of foot drop is peroneal nerve injury. The peroneal nerve is a branch of the sciatic nerve. It supplies movement and sensation to the lower leg, foot, and toes.
