Working the Peroneal Nerve Through the Fibular Head
The common peroneal nerve wraps around the neck of the fibula just below the lateral knee. It is the most superficial point where the nerve can get stuck, irritated, or compressed. People usually notice it as foot drop, a numb strip running down the outside of the lower leg, or a burning sensation that jumps into the top of the foot. The exercises I am about to lay out are not cures. They are neural mobilization techniques designed to reduce adhesions and improve the nerve's ability to slide through its sheath and surrounding tissue. Nothing fancy. Just repeatable, controlled movements. I want to address the technique first because most people mess up the basic execution before they even get to the second set. The peroneal nerve glide works by creating a sequential tension chain: you extend the knee, dorsiflex the ankle, and extend the big toe in one smooth motion, then release back through the same sequence. The goal is not to stretch the nerve. You are gliding it through the fibular tunnel and the subcutaneous tissue around it. If you feel sharp pain or electric shocks shooting down into the foot, you have gone too far and you are aggravating the nerve instead of helping it. Stop immediately. The sensation should be a mild pulling or tension along the lateral knee and outer shin, nothing more. Here is the exact movement I have clients do. Start seated on a flat surface with your leg extended. Slowly straighten the knee until you feel the first bit of tension behind the knee and outer shin. Then dorsiflex the ankle, pulling the toes up toward the shin. Finally, extend the big toe upward. Hold for two seconds. Reverse the sequence exactly: bend the knee, point the toes, curl the big toe back down. That is one repetition. Ten reps, two to three times a day. Most people see improvement within three to four weeks if they stay consistent. Some take longer. A few do not respond at all and need imaging to rule out a structural lesion like a ganglion cyst compressing the nerve at the fibular head.
There is a second variation that adds value if the basic glide is not producing results. It is called the supine slump glide. Lie on your back, lift the affected leg, bend the knee to about ninety degrees, then slowly straighten the knee while dorsiflexing the ankle. This increases the tension gradient along the entire sciatic to peroneal pathway. Use this one only if the seated version is not enough and you are not experiencing increased symptoms after the session. I generally recommend introducing it no earlier than week three of the program. I should mention something I learned the hard way. About two years ago a client came in with what I assumed was typical peroneal neuropathy at the fibular head. The nerve glide exercises made things worse instead of better. His symptoms were actually increasing in severity with each session. We eventually got an MRI and found a small synovial cyst originating from the proximal tibiofibular joint compressing the nerve. No amount of gliding was going to fix that. The takeaway is straightforward: if your symptoms worsen after one to two weeks of consistent exercise, stop and get imaging. Do not push through worsening nerve pain. Pushing through can turn a reversible entrapment into chronic neuropathy, and that is a much longer road back. There is a nuance most guides skip over. The peroneal nerve has two branches after it splits: the deep peroneal nerve, which controls dorsiflexion and sensation between the first and second toe, and the superficial peroneal nerve, which supplies the lateral lower leg and most of the top of the foot. Depending on where the compression is happening, one branch may be more symptomatic than the other. If your main issue is foot drop with weak toe extension, the deep branch is likely involved. If your symptoms are mostly numbness and burning along the outer lower leg and foot, the superficial branch is the culprit. The exercise protocol is the same, but the intensity and pace should differ. The deep branch tends to tolerate more aggression. The superficial branch is more sensitive and requires slower, gentler repetitions, especially in the early weeks.
Another thing to keep in mind is that these exercises are a treatment, not a prevention strategy. If you are the type who crosses your legs for hours, sits with your ankles pinned under a chair edge, or recently had prolonged immobilization in a cast, the exercises will help but they will not prevent recurrence unless you change the behavior causing the compression. The fibular head is exposed and vulnerable. Removing the source of pressure matters more than any exercise routine. For anyone looking for a structured routine to follow, here is a printable format you can save or print. It is not tied to any software or platform. It is just a plain reference sheet.

Set one: Seated glide. 10 reps, hold 2 seconds at end range. Rest 30 seconds between sets. Two sets. Set two: Deep breathing and gentle ankle pumps while seated. 30 repetitions. This keeps blood flow moving through the area without loading the nerve. Set three: Supine slump glide (introduce only if week three or later and symptoms are stable). 8 reps, hold 2 seconds. One set only.
Do this once in the morning and once in the evening. Track symptoms on a simple scale from zero to ten each day. If the average score goes up for two consecutive days, drop the supine variation and stick to the seated glide until the scores stabilize. The results are predictable but slow. Most patients report a noticeable decrease in numbness and a return of some dorsiflexion strength within four to six weeks. Full recovery can take three to six months depending on how long the nerve was compressed before treatment started. If there is no improvement at all after six weeks of consistent daily work, the next step is a referral to a neurologist for conduction studies and possibly surgical consultation if a structural cause is found. I have seen too many people treat this condition with heat, massage, and random stretching and wonder why nothing changes. Heat feels good but does not address the mechanical sliding problem. Massage to the area around the fibular head can sometimes make things worse by irritating an already compressed nerve. The nerve needs controlled gliding, not aggressive soft tissue work in the exact spot where it is compressed. Icing helps if there is acute inflammation, but again, it does not fix the underlying issue.
If you want resources, there are a few solid references. The original work by Butler on neural mobilization is the standard text. His books go into much more detail on the biomechanics of nerve gliding than anything I can summarize here. There are also YouTube videos from licensed physical therapists demonstrating the seated and supine techniques. Watch them once to confirm your form, but do not rely on them as a substitute for professional assessment if your symptoms are significant or worsening. One final practical note. Some people find that adding a gentle hip abductor and external rotator stretch helps because tight musculature in the lateral hip and thigh can contribute to downstream tension on the peroneal nerve. It is not the primary treatment, but it is a reasonable adjunct. Try a standing piriformis stretch and a side-lying hip abduction hold for thirty seconds each, two sets, three times per week. Nothing complicated.
