Damage or injury to the dorsiflexor muscles (tibialis anterior, extensor hallucis longus, extensor digitorum longus) or along the neural pathway that controls the dorsiflexor muscles can lead to "foot drop". For instance, the peroneal nerve controls the dorsiflexor muscles that lift the foot which runs near the surface of the skin on the lateral side of the knee. The funiculi of the peroneal nerve are larger and have less connective tissue than the tibial nerve. Hence, making the peroneal nerve more susceptible to injury/trauma. Foot drop is typically caused by a pathology affecting the LMN (Lower Motor Neurons), usually due to a conduction disorder from the deep peroneal nerve (L4-L5). The most common cause of foot drop is L4-L5 radiculopathy,
