Plantar flexion explains the expansion of the fish eye so the the foot clues down and away indigenous the leg.

When in a was standing position, this would median pointing the foot in the direction of the floor.

Plantar flexion has actually a normal variety of activity from around 20 to 50 degrees from the resting position.

In this article, we research the tasks in which plantar flexion might occur, the muscles behind it, and what happens once injuries happen to these muscles.

Share top top PinterestPlantar flexion is a term that describes positioning the foot through the toes the furthest down. Was standing on tiptoes is an example of plantar flexion.
Many daily activities involve plantar flexion. One usual example is pushing the foot down on the gas pedal in a car.

Standing ~ above the advice of the toes to with a high shelf is likewise plantar flexion. Ballet dancers who dance top top the advice of their toes (en pointe) have actually an extreme selection of activity in their plantar flexion.

These are more noticeable develops of plantar flexion, yet plantar flexion takes ar with every step a human being takes.

Daily tasks that call for plantar flexion include:

Nearly every sport will require the usage of plantar flexion. As a result, athletes room often encouraged to treatment for your ankles and also the neighboring muscles as lot as possible.


What controls plantar flexion?

Plantar flexion seems prefer a straightforward act, yet it requires an entire group that muscles and tendons in the leg and foot.

Most muscle are focused on the tibia (shin bone) and also the fibula, i beg your pardon is a thinner bone that supports the tibia. Muscles also attach come the ankle and various skeleton in the foot.

Gastrocnemius

The gastrocnemius is a muscle the forms half of what is typically called the calf muscle. It starts at the back of the knee and attaches to the Achilles tendon in ~ the heel.

The gastrocnemius is one of the muscles that does most of the work-related in plantar flexion.

Soleus

This is a broad and strong muscle that additionally starts behind the knee and runs beneath the gastrocnemius. It merges into the gastrocnemius to develop the Achilles tendon in ~ the heel.

The soleus muscle is responsible for pushing far from the ground. It is vitally crucial for any type of movement entailing plantar flexion.

Plantaris

The plantaris muscle start behind the knee, just above the gastrocnemius. The plantaris tendon runs below both the soleus and also gastrocnemius muscles to attach directly with the heel bone.

This muscle works with the Achilles tendon to flex both the ankle and also knee joints, allowing a human being to stand on their toes or allude their foot in plantar flexion.

Flexor hallucis longus

This is just one of the three deep muscles of the leg. The starts follow me the ago of the fibula and also goes with the ankle, running along the sole of the foot to connect to the big toe.

The flexis hallucis longus helps plantar flexion of the ankle, and also plays a big role in curling the toes. It is an extremely important because that walking and balancing, especially while top top tiptoe.

Flexor digitorum longus

This is one more deep muscle in the leg. The flexor digitorium longus start on the earlier of the tibia close to the soleus muscle. The muscle fibers finish in a tendon the travels through the ankle and also runs follow me the bottom that the foot.

The flexor digitorium longus attaches to every toe except the huge toe. That is this muscle that provides the power to flex the toe themselves. It helps to support the arch the the foot and also is offered in plantar flexion.

Tibialis posterior

The tibialis posterior is the third deep muscle in the leg. That is the most central leg muscle and also is crucial in keeping the reduced leg stable.

It is attached to interosseous membrane (which separates every bones) in the leg and is connected to the tibia and fibula. The tendon the the tibialis posterior spreads the end to attach to the metatarsals, which space the 5 long bones in the peak of the foot. The tibialis posterior is likewise attached to various other bones in the foot – the medial cuneiform, middle and lateral cuneiform, and also navicular bones.

Peroneus longus


Share on PinterestThe peroneus brevis ensures the foot is stable and also any injury may weaken the ability to carry out plantar flexion.

The peroneus longus muscle starts at the upper ar of the fibula. It operation down many of the fibula bone and attaches come the medial cuneiform and first metatarsal, which room the bones listed below the huge “knuckle” that the big toe.

The tibialis posterior and the peroneus longus job-related together in the center foot to produce support because that the weight-bearing arches of the foot. These two muscles aid keep the ankle stable as soon as standing or increasing onto the toes.

Peroneus brevis

The peroneus brevis lies just underneath the peroneus longus. That starts in the column of the fibula, and the tendon follow me to the foot, where it attaches come the metatarsal that the small toe. The peroneus longus and also peroneus brevis help keep the foot stable.

All these muscles and tendons occupational together in plantar flexion to help the body remain balanced and also stable. When there is a difficulty with even one of these muscles or tendons, the whole system is weakened, causing injury and a reduced selection of motion.


An injury to any kind of one of the muscles sustaining the plot of plantar flexion will certainly limit the selection of movement of the foot. Fish eye injuries are one of the most usual ways come severely border plantar flexion.

The fish eye is a very facility joint. The is capable of a wide variety of activity to stabilize the body in the most difficult situations, such together hiking or jumping ~ above uneven surfaces. The does this while likewise protecting crucial ligaments, arteries, and nerves.

When the fishing eye is injured, inflammation helps prevent added injury by to reduce the variety of motion of the foot. This can substantially reduce plantar flexion, sometimes to the level where a human cannot move their foot.

Ankle injuries can selection in severity native mild sprains to major fractures. The severity that the injury will recognize the treatment.


Treating injuries depends on the type of injury the the person has actually sustained. Mild ankle sprains carry out not require casts or splints. Instead, they deserve to be treated with rest, ice, compression, and also elevation, well-known as the RICE method.

More significant sprains, tendon injuries, and some fractures will require a splint or cast to organize the fishing eye in its ideal position. Throughout this time, an individual will not be able to put weight on your foot or ankle.

If the fishing eye is not secure where the fracture has actually occurred, surgery is usually required. This may mean putting a key or screws into the skeleton of the fishing eye to store it in place while that heals. It typically takes a minimum that 6 weeks for a fracture come heal.

All develops of ankle, leg, or foot injury that affect plantar flexion will involve physics therapy and exercise to strengthen the muscles and also tendons and also protect them from future injury. Failing to execute these practice puts world at risk of more injuries in the future.


Preventing injuries in the muscles and also joints that regulate plantar flexion starts with doing consistent mobility and strength work. Over there are countless exercises that have the right to be done to combine the muscles and also tendons the are used in plantar flexion and assist protect the ankle.

Simple practice such together toe raises can develop strength. Low affect exercise such together swimming and biking can additionally promote flexibility and strength in the legs, feet, and also ankles.

Stepping correctly can also aid prevent injuries. Untrue walking trends may add to injuries over time. This can incorporate walking in high heels or poorly equipment shoes.

Taking mindful steps can help if a person has actually a tendency to end correct or action incorrectly. It have the right to also aid to to walk barefoot because that at the very least 30 minutes each day, to enable the feet to walk in their herbal position.

An appointment v a podiatrist or orthopedic operated doctor may aid anyone with regular injuries or limited plantar flexion to discover a solution. This may aid the doctor know a who walking pattern and also decide whether they would advantage from details shoes or specific exercises.
