Peroneal Muscles, Weak Ankles, & Trigger Points



The ankles and the lower legs have a casual relationship by allowing movement to the foot that causes an up-and-down motion. The lower leg has various muscles and tendons that surround the shin bone and allows the feet to take the body from one location to another. The peroneal muscles in the legs allow ankle stability to ensure that the weight from the host’s body doesn’t cause overload to the legs and ankles. However, factors like obesity, trauma, or overexerting can cause the peroneal muscles to be inflamed and develop issues like weak ankles or trigger points that can cause referred pain to the ankles and affect how a person walks. Today’s article examines the peroneal muscles, how weak ankles correlate with trigger points, and ways to strengthen the ankles while managing trigger points. We refer patients to certified providers that incorporate various techniques in the lower body extremities, like lower leg and ankle pain therapies correlating to trigger points, to aid many people dealing with pain symptoms along the peroneal muscles, causing weak ankles. We encourage and appreciate each patient by referring them to associated medical providers based on their diagnosis when it is appropriate. We understand that education is an excellent way when asking our providers intricated questions at the patient’s request and understanding. Dr. Alex Jimenez, D.C., only utilizes this information as an educational service. Disclaimer

The Peroneal Muscles On The Ankles

Have you been experiencing pain when walking around constantly? What about feeling a sharp or dull ache in the back or side of your legs? Or do you feel like falling when you are just standing around? Many people experiencing these issues on their legs and ankles could be dealing with trigger points along the peroneal muscles in the ankles. The peroneal muscles consist of two muscles in the lateral compartment of the lower legs: the peroneus longus and peroneus brevis. The peroneus longus is an important long muscle in the lower legs as it is at the top of the fibula and then runs down the outer leg while connecting to the foot. One of the primary functions of the peroneus longus is allowing plantarflex and evert the foot at the ankle. This means that the peroneus longus helps provide motor strength and range of motion to the ankles. 



The peroneus brevis is one of the shorter peroneal muscles in the legs that go down to the ankles and provides assistance to allow eversion to the foot and plantarflexion to the ankles. This shorter muscle is important since the ankle joint is relatively mobile and needs stability from the surrounding ligaments and muscles. These two muscles work together for ankle stability when walking and positioning when the body is moving. Studies reveal that depending on a person’s environment, the peroneal muscles allow support and stability to the ankle in various positions. A good example is if the foot is placed in a sloped position, the peroneal muscles and the surrounding ligaments help stabilize the ankle so it won’t induce pain, causing the individual not to fall over. 


Weak Ankles & Trigger Points


When factors like obesity, trauma, or injuries begin to affect the lower half of the body, it can cause instability in the legs and cause the surrounding muscles, tendons, and ligaments to be overstretched, take on more of an overload to the legs, or suffer from a muscle or tendon tear. These factors are associated with various issues that can invoke pain along with developing trigger points along the lower legs. When there are issues in the peroneal muscles, it can lead to muscle weakness in the ankles or “weak ankles,” which causes instability in the body and causes the individual to sprain their ankles. Studies reveal that when the peroneal tendons have a tear in the lower extremities, it can lead to lateral ankle pain that is often missed when examined. However, to that point, if the incision has been left untreated, it can lead to persistent ankle pain, instability, and ankle dysfunction. In “Myofascial Pain and Dysfunction,” written by Dr. Janet G. Travell, M.D., stated that when individuals suffer from weak ankles or have an ankle sprain, active trigger points can cause pain and tenderness to the ankles and cause the person to become unstable. If left untreated, it can cause them to lose balance and have foot drop and ankle fractures to their foot. The book also mentioned that any ruptures in the tendons and muscles might cause lateral compartment syndrome. When there is instability in the ankles, many people resort to using mobility aids like a cane or a walker to be mobile to compensate for the function lost in their feet.


Trigger Point Therapy On The Peroneal Muscles- Video

Do you feel the pain from the bottom of your feet to your ankles? Does it hurt to walk around for a short period? Or have you sprained your ankle, and there is a dull ache when you try to rotate? Some ankle issues are associated with trigger points affecting the peroneal muscles. The peroneal muscles help the lower legs by allowing eversion to the foot and plantarflexion to the ankles. The two muscles that make up the peroneal muscles are the peroneus longus and the peroneus brevis, and they, along with the other tendons and ligaments, help with ankle stability. Since the ankle is a mobile joint, it can succumb to sprains, tears, and instability in the body, allowing trigger points to develop and causing even more issues. The great news is that there are ways to manage trigger points along the peroneal muscles and reduce ankle instability. The video above shows where the peroneal muscles are located on the leg, where the trigger points are, and how to use K-tape to help support the ankle and prevent more injuries on this moveable joint.

Strengthening The Ankles & Managing Trigger Points


Instability in the ankles can be a bummer to many individuals that are on the move, but when it comes to treatment, it can prevent future injuries from re-occurring. Studies reveal that when pain specialists incorporate joint mobilization techniques and dry needling therapy into their patients, it can allow them to reduce the pain and disability to the ankles, thus managing the trigger points along the peroneal muscles. Another way many people can reduce pain in their peroneal muscles is by incorporating stretches and exercises to strengthen their ankles. This allows the peroneal muscles to be loose and gently stretched while slowly strengthening the ankles in a semi-lock position. When people utilize these techniques on their legs and ankles, it can bring mobility and stability back to the body without fear of falling or causing more issues in the ankles. 



As one of the most mobile skeletal joints in the lower body, the ankles work together with the legs to provide mobility and stability to the body. The lower legs have various muscles, tendons, and ligaments that travel down and help support the legs and ankles. One of the muscles that provide that support is the peroneal muscle. The peroneal muscles consist of two muscles known as the peroneus longus and peroneus brevis help with eversion to the foot and allow plantarflexion to the ankle. When a person has sprained their ankle, it causes the peroneal muscle to become overstretched and develop trigger points. The great news is that trigger points are treatable, and various treatments can reduce pain in the affected muscle. This allows stability and mobility back to the ankles and improves the body’s functionality.
