Peroneal Nerve Entrapment Exercises

Common peroneal nerve injury and entrapment often causes pain, tingling, or numbness along the outer lower leg and the top of the foot. Common symptoms include foot drop (difficulty lifting the foot), muscle weakness, and impaired nerve function in the superficial and deep branches of the peroneal nerve. This condition may mimic other nerve entrapments, such as tibial or sciatic nerve dysfunction.

Diagnosis begins with a physical examination focusing on the affected leg, fibular head, and lower limb. Tests like nerve conduction studies, electromyography (EMG), or nerve ultrasound can assess the extent of nerve compression or damage. Imaging techniques like MRI help identify underlying causes like scar tissue, fibula fractures, or entrapment neuropathies involving the common or superficial peroneal nerve.

Prevention involves maintaining proper muscle strength and flexibility in the lower leg through exercises targeting the peroneal muscles, tibialis anterior, and calf muscles. Avoid prolonged pressure on the knee or lower leg, especially during prolonged bed rest or after knee surgery. Wearing supportive footwear, addressing underlying conditions like lumbar radiculopathy, and using nerve gliding techniques or electrical stimulation can also reduce the risk of compressive peroneal neuropathy.
