Examples of exercises
- Sit on the ground with the feet straight out in front.
- Take the towel and wrap it around the toes on one foot.
- Gently pull back until a stretch runs from the bottom of the foot up to the back of the lower leg.
- Hold this stretch for 30–60 seconds.
- Switch to the other leg and repeat.
Six weeks after surgery, patients may resume running. With mild and/or intermittent symptoms, relief of numbness, tingling, and pain is often immediate. With long-standing or severe cases, relief of symptoms and return of muscle function may be more gradual and over the course of many months.
This is because crossing the legs can put pressure on the peroneal nerve behind the knee, which supplies sensation to the lower legs and feet. But if you do give yourself pins and needles this way, it is only temporary.
Peroneal nerve dysfunction is typically diagnosed by a physical examination of the legs and feet. An MRI or CT scan may be used to confirm the compression of the nerve. Electrodiagnostic tests such as EMGs and NCVs may also be used to confirm the diagnosis.
You're likely to start by seeing your family doctor. Depending on the suspected cause of foot drop, you may be referred to a doctor who specializes in brain and nerve disorders (neurologist).
A peroneal nerve injury is damage to the nerve on the outer part of the lower knee. This nerve sends impulses to and from the leg, foot, and toes. Damage can cause weakness, numbness, and pain. It may also make it hard for a person to lift their foot.
The most common cause of foot drop is compression of a nerve in your leg that controls the muscles involved in lifting the foot (peroneal nerve). This nerve can also be injured during hip or knee replacement surgery, which may cause foot drop.
The telltale sign of foot drop is catching your toes on the ground as you walk. A physical therapist can help treat the condition with exercises and other modalities. The main goal of physical therapy for foot drop is to improve functional mobility related to walking.
The most common etiology is habitual leg crossing (which compresses this area). Prolonged positioning with pressure at this area (e.g. sitting on an airplane or positioning during surgery) are other causes. Peroneal nerve entrapment has been reported at the fibular head on the hemiparetic side in stroke patients.
If your nerve is bruised or traumatized but is not cut, it should recover over 6-12 weeks. A nerve that is cut will grow at 1mm per day, after about a 4 week period of 'rest' following your injury. Some people notice continued improvement over many months.
You may lift your foot higher than usual when walking to prevent this. Recovery depends on the cause of foot drop and how long you have had it. In some cases, it can be permanent. Making small changes in your home, such as removing clutter and using non-slip rugs and mats, can help prevent falls.
Typically, damaged nerve fibres of the central nervous system (CNS) in the brain, the optic nerve and spinal cord don't have the ability to regenerate.
