This nerve innervates the anterior muscles of the leg that are used during dorsiflexion of the ankle. The muscles that are used in plantar flexion are innervated by the tibial nerve and often develop tightness in the presence of foot drop. The muscles that keep the ankle from supination (as from an ankle sprain) are also innervated by the peroneal nerve, and it is not uncommon to find weakness in this area as well. Paraesthesia in the lower leg, particularly on the top of the foot and ankle, also can accompany foot drop, although it is not in all instances. A common yoga kneeling exercise, the Varjrasana has, under the name "yoga foot drop," been linked to foot drop. Treatment
The underlying disorder must be treated. For example, if a spinal disc herniation in the low back is impinging on the nerve that goes to the leg and causing symptoms of foot drop, then the herniated disc should be treated. If the foot drop is the result of a peripheral nerve injury, a window for recovery of 18 months to 2 years is often advised. If it is apparent that no recovery of nerve function takes place, surgical intervention to repair or graft the nerve can be considered, although results from this type of intervention are mixed.Non-surgical treatments for spinal stenosis include a suitable exercise program developed by a physical therapist, activity modification (avoiding activities that cause advanced symptoms of spinal stenosis), epidural injections, and anti-inflammatory medications like ibuprofen or aspirin.
FES is applied to lower extremities for improving functional walking in stroke patients;  for the correction of foot drop. They have benefited patients by improving gait speed, muscle strength and other functions.Treatment for some can be as easy as an underside "L" shaped foot-up ankle support (ankle-foot orthoses). Another method uses a cuff placed around the patients ankle, and a topside spring and hook installed under the shoelaces. The hook connects to the ankle cuff and lifts the shoe up when the patient walks. Both these techniques show significant improvement on usage. Identification of a suspect in a murder case
In December 2021, police in Toronto, Canada said they were looking for a person with a distinctive gait as a suspect in the murder of Barry Sherman and Honey Sherman. Medical professionals  quoted by the Toronto Star said that the distinctive gait could  be caused by foot drop. See also
