What Are The Symptoms Of A Peroneal Nerve Injury
A common sign of a peroneal nerve injury is development of a foot drop. A foot drop is a distinctive way of walking. It occurs when you cant flex your ankle to take a step forward. Instead, you may lift one knee higher than the other to raise your foot off the ground.
Other peroneal nerve injury symptoms include:
- Inability to move your foot.
- Inability to flex your toes or ankles upward .
- Loss of sensation in your shin or the top of your foot.
- Pain in your foot or lower leg.

This breakthrough device can calm the nerves and increase blood flow which allows the nerve cells the potential to recover.
What Surgical Treatments Are Offered At The Institute For Advanced Reconstruction For Foot Drop
Our surgeons perform surgery to get to the root of the problem causing a patients foot drop. Following a physical exam, additional testing may be needed to determine the cause of foot drop in order to develop the best treatment plan. Testing may include imaging studies such as x-rays, CT scan or an MRI to rule out any soft tissue or bone abnormalities that may be causing foot drop. Nerve tests, such as an EMG are used to identify damage of the affected nerve.
If the patients foot drop is indeed the result of nerve problems, their foot drop treatment would likely take the form of nerve surgery to relieve pressure on the nerve . If that type of surgery is not possible, nerve reconstruction, tendon transfer or alternative methods of reconstruction may be necessary to help return function. Your reconstructive surgeon will determine which surgical technique is needed in your specific case.

What Causes Drop Foot
Foot drop causes include problems that are neurological, anatomical and muscular in nature, with the most common cause of foot drop being peroneal nerve damage or compression.
Peroneal Nerve: The Foot Drop NerveTaking a look at foot nerve anatomy, the peroneal nerve is a branch of the sciatic nerve that extends from the low back and controls the muscles responsible for lifting the foot. It wraps around the leg from the back of the knee to the front of the shin and lies pretty close to the surface of the skin. This makes it vulnerable to being pinched in quite a few scenarios, including:
- Trauma to the knee or shin
- A dislocated knee or fractured fibula
- Knee or hip replacement surgery
- Long hours kneeling or in a squatted position
- Habitual leg crossing
- Wearing a leg cast
Other Causes of Foot Drop
- Amyotrophic lateral sclerosis
- Muscular dystrophy
- Parkinsons disease
How Can Nerve Stimulation Help Treat Foot Drop
Although managing foot drop can be challenging, there are many treatments available. Treatment depends on the cause and severity of your foot drop. For example, when foot drop is caused by a neurological injury like stroke or damage to the peroneal nerve, the best treatment approach is rewiring the brain and nerves through neuroplasticity.
Neuroplasticity helps strengthen the neural connections needed to execute a movement, like dorsiflexion. This is best achieved through high repetition of foot drop exercises. The more a movement is practiced, the more the brain will recognize that movement and strengthen its neural connections.
While rehabilitation exercises are essential to treat the root cause of foot drop, this can be particularly challenging for individuals with limited mobility. Fortunately, there are other treatment methods to promote neuroplasticity, such as nerve stimulation, also called neuromuscular electrical stimulation.
Nerve stimulation for foot drop involves placing electrodes on the lower leg muscles and sending electrical impulses through the skin. These electrical impulses help create a contraction in the affected muscles, like the tibialis anterior. Activating these muscles encourages dorsiflexion and stimulates the brain, strengthening the muscles and improving neural pathways. When used consistently, this can help reduce foot drop.

Treatment For Foot Drop
How foot drop is treated depends on what’s causing it and how long you have had it for.
Sometimes it can get better on its own.
Common treatments for foot drop include:
- physiotherapy to strengthen or stretch the muscles in your leg and foot
- braces, splints or shoe inserts to help hold the foot in position
- a small device that’s put in your body and uses electrical signals to help your nerves work especially if you’ve had a stroke or have multiple sclerosis
If you have permanent loss of movement from foot drop, you may have surgery to fuse the ankle and foot joints, or repair or graft the nerve.
Treating Foot Drop With Nerve Stimulation: How Electricity Can Promote Recovery
Foot drop is characterized by the inability to lift the front of the foot toward the shin, known as dorsiflexion. Fortunately, there are various types of treatments that can help manage and improve foot drop such as nerve stimulation.
Foot drop treatments like nerve stimulation help encourage neuroplasticity, the brains natural ability to rewire itself. When foot drop is caused by neurological injury such as a stroke, neuroplasticity is the key to recovery.
This article will discuss how nerve stimulation can be used to treat foot drop, lower the risk of further injury, and help maximize recovery.

Data Processing And Statistical Analysis
Within-subject averaged success rates were calculated for each of the ART categories and for each device condition . To determine whether the participants’ obstacle avoidance ability differed between walking with an AFO and with FES, the success rates were subjected to an analysis of variance for repeated measures. Time , device , and ART were used as within-subject factors. To stabilize the variance in the success rates, the data were subjected to angular transformation before conducting the ANOVA.
To investigate whether the expected benefits of FES with regard to obstacle avoidance ability depended on clinical characteristics of the participants, bivariate nonparametric correlations were calculated between the increase in success rates with FES at week 8 and each of the following characteristics: Modified Ashworth Scale score , lower-extremity Motricity Index score, lower-extremity Fugl-Meyer Assessment score, Berg Balance Scale scores, and comfortable walking speed with the AFO. Subsequently, the analysis of obstacle avoidance ability with AFO and FES was adjusted for the clinical characteristics that demonstrated significant correlations by adding them to the statistical model as covariates . We used SPSS version 15.0 for all statistical analyses. The level of significance was set at P.05.
What Causes Foot Drop
The brain is responsible for sending nerve signals to the muscles telling them when to contract and relax. When the areas of the brain responsible for controlling movement, such as the motor cortex, are affected by a neurological injury like TBI or stroke, the muscles are unable to receive appropriate signals. As a result, movements like dorsiflexion can become impaired, resulting in foot drop.
Another common cause of foot drop is injury to the peroneal nerve. The peroneal nerve is a branch of the sciatic nerve that wraps from the back of the knee to the outside of the lower leg. Because the nerve is very close to the surface, it can become easily damaged, especially after an injury.
The peroneal nerve is particularly important because it controls the muscles that lift your foot, such as the tibialis anterior. Damage to this nerve can impair dorsiflexion and result in foot drop, making it difficult to walk and safely navigate around. Damage to the peroneal nerve can occur from sports injuries, fracture, or hip or knee replacement surgery.

Improving The Efficacy Of Fes By Changing The Aim Of Treatment
Artificial neural networks can be trained to learn and predict complex non-linear relationships, Unpublished data from this lab has demonstrated the capability for neural networks to learn stimulation parameters for generating specific EMG signals in the rat hind limb, if extended to the FES devices could theoretically be capable of predicting stimulation parameters in real time on a low power device . Although this requires recording from a large patient cohort to provide enough generalization across subjects and conditions, combining this with muscle synergy prediction previously described would provide advanced stimulation control in a true-closed loop device. Due to the flexibility of training these networks as the network updates to the observed EMG parameters generated it can generate novel stimulation strategies relying on the simultaneous contraction of separate muscle groups. This could allow for better recruitment of remaining connections in more extensively damaged networks. In the same manner that the network can update to match recovery, the network will also continue to adapt to the degradation of the nervous system thus providing a longer period of improved mobility and quality of life for patients with chronic conditions.
Symptoms Associated With Foot Drop
When this nerve is compressed, it can cause difficulties with lifting the front part of the foot, making your toes drag as you walk. Other symptoms of foot drop include
- Walking with your knees higher than normal to lift the foot
- Muscle weakness in the affected leg
- Tingling or numbness in your foot or leg
- Curling of your toes
If youre experiencing any of these symptoms, dont wait to seek medical help. Waiting to begin treatment for foot drop can make the condition more difficult to treat.

Anterior Compartmental Syndrome Of The Leg
Acute unilateral foot drop may be a manifestation of the anterior compartmental syndrome of the leg, in which increased pressure within a limited space compromises the perfusion, circulation, and function of the contents of that space. This may occur following limb trauma , spontaneous bleeding into a compartment, or strenuous exercise such as running. Tissue pressure higher than 60 mmHg is usually diagnostic. Anterior compartmental syndrome of the leg often results in foot drop since the compartment contains all muscles that function as ankle and toe dorsiflexors . Characteristic findings of anterior compartmental syndrome not present in other causes of foot drop include severe leg pain, out of proportion to what is anticipated from the clinical situation pain on flexion of toes and plantar flexion of ankle, which lead to passive stretch of the anterior compartmental muscles of the leg and a tenseness of the anterior compartmental fascia.

At The Institute for Advanced Reconstruction we have foot drop doctors and specialists in-house that offer consultations and treatment options.
What Is A Peroneal Nerve Injury
A peroneal nerve injury is dysfunction of your common peroneal nerve. The common peroneal nerve helps you feel sensations in the front and sides of your legs. It also allows you to lift your toes and ankles.
The peroneal nerve starts near your sciatic nerve at the top of your glutes . It travels down the back of your thigh until it reaches your knee, where the nerve wraps around the front of your leg and extends all the way down to your toes.
Peroneal nerve injuries may cause pins-and-needles sensations, pain or weakness. You may also have a foot drop, a problem that occurs when you cant lift your foot upward at the ankle.
What is the difference between the superficial and deep peroneal nerve?
Around your knee, your common peroneal nerve splits into two branches:
- Deep peroneal nerve: This branch runs on the inside of your leg and over your ankle bone. It helps control function on the inside of your foot, including your big and second toe.
- Superficial peroneal nerve: This branch runs on the outside of your leg. Its responsible for sensation in the outer two-thirds of your leg and the top of your foot. It helps control the movement of all your other toes.
Who might get a peroneal nerve injury?
Anyone can develop a peroneal nerve injury. But you are more likely to have the problem if you have certain health conditions or injuries, such as:
