Dorsiflexion is the backward bending and contracting of the hand or foot. It is the extension of the foot at the ankle and the hand at the wrist. Dorsiflexion occurs thanks to the muscles in the anterior tibialis (the front part of the shin that lifts the foot). Poor dorsiflexion can cause a range of issues, from shin pain to knee injuries and plantar fascia issues. It can also affect basic athletic movements such as squatting and lunging.

Dorsiflexion is the backward bending and contracting of the foot at the ankle
The tibialis anterior, located in the front part of the shin, is the main muscle responsible for dorsiflexion. It is the strongest dorsiflexor of the ankle and is also involved in inversion, which is the action of turning the sole of the foot inward. Other muscles that aid dorsiflexion include the extensor hallucis longus, which is responsible for extending or pulling back the big toe, and the extensor digitorum longus, found in the front of the lower leg.
Poor dorsiflexion can cause a range of issues for athletes, including a "loose" or "floppy" foot, which can lead to injuries such as shin splints and runner's knee. It can also affect more basic athletic movements such as squatting and lunging. Restricted dorsiflexion can be caused by several factors, including tight calves, flat feet, and ankle injuries.
To improve dorsiflexion, various exercises can be performed, including squats, lunges, and calf stretches. Training barefoot can also help, as shoes can be restrictive and limit natural dorsiflexion. In some cases, working with a personal trainer or movement therapist may be beneficial to address restricted dorsiflexion.

The tibialis anterior is the strongest dorsiflexor of the ankle
The tibialis anterior tendon (TAT) passes beneath the extensor retinaculum, which holds the TAT in place. However, in 25% of cases, the tendon passes through a separate tunnel formed by the superior extensor retinaculum. The tibialis anterior is an essential component in the ankle and knee joint structure. It functions as a dorsiflexor and as a dynamic stabiliser of the ankle joint during running and jumping. The tibialis anterior also helps maintain the axis of the ankle joint during dorsiflexion.
Dorsiflexion is the backward bending and contracting of the foot at the ankle. It is a critical movement in gait, as it allows the foot to clear off the ground during the swing phase. Proper dorsiflexion results in a correct foot strike and contributes to injury prevention. When running, dorsiflexion puts the foot in an ideal position to absorb the shock of landing and spring forward into the next stride.
Poor dorsiflexion can cause a 'loose' or 'floppy' foot due to relaxation at the ankle joint. This can lead to striking the ground through the toes, resulting in poor force distribution and injuries such as shin splints and runner's knee. Restricted dorsiflexion can be caused by tight calves, flat feet, or ankle impairments. Techniques to improve dorsiflexion include stretching the calves and connective tissue in the foot, as well as specific ankle mobility exercises.

Poor dorsiflexion can lead to injuries such as shin splints and runner's knee
Poor dorsiflexion can cause a 'loose' or 'floppy' foot, resulting in a poor distribution of force that can lead to injuries such as shin splints and runner's knee. The condition is characterised by achiness and/or acute pain in the front side of the tibia (shin bone) while the foot is dorsiflexed. It is often caused by a combination of factors, including weak or inflexible calves, flat feet, overpronation, worn-out or inappropriate footwear, and overload.
To prevent and treat shin splints, it is recommended to perform the ankle dorsiflexion stretch before and after exercising. This stretch targets the calves and Achilles heels, preventing them from becoming too tight and improving dorsiflexion. Additionally, following the RICE (Rest, Ice, Compression, Elevation) method can help alleviate pain and swelling associated with shin splints.
Runner's knee, or patellofemoral pain syndrome (PFPS), refers to pain in the front of the knee or around the kneecap. It can be caused by structural defects, walking or running form, or other factors. Poor dorsiflexion can contribute to runner's knee by affecting the alignment and force distribution at the knee joint.
To summarise, poor dorsiflexion can lead to injuries such as shin splints and runner's knee due to improper force distribution and joint alignment. Addressing poor dorsiflexion through targeted stretches and improving running form can help prevent and manage these injuries.

Tight calves and flat feet can negatively affect dorsiflexion
Dorsiflexion is the movement of raising the foot upwards towards the shin. It is a crucial aspect of running and walking, as it helps to absorb the shock of landing and propel the body forward. While dorsiflexion seems like a simple motion, several factors can hinder it, including tight calves and flat feet.
Tight calves can restrict dorsiflexion by limiting the range of motion at the ankle joint. The gastrocnemius and soleus muscles, which cross the ankle joint, can become tight and restrict the upward movement of the foot. This tightness can lead to a reduced ability to utilise power from the posterior chain muscles, affecting athletic performance. Additionally, tight calves can contribute to poor force distribution during activities like running, increasing the risk of injuries such as shin splints and runner's knee.
To improve dorsiflexion limited by tight calves, specific stretches can be performed. One stretch is the gastrocnemius stretch, where the back leg is kept straight while the front knee is forward, creating a stretch that is held for 20 seconds. Another stretch targets the soleus muscle. For this stretch, lean against a wall with the leg needing stretching positioned at the back, and bend the knee with the heel on the ground until a stretch is felt, holding for 20 seconds. A third option is to stretch on a step by placing the foot on the step and then lowering the heel down until a stretch is achieved, again holding for 20 seconds.
Flat feet, or overpronation of the foot, can also negatively affect dorsiflexion and contribute to long-term knee injuries. The foot's position during dorsiflexion is crucial for proper foot strike and injury prevention. Flat feet can alter the angle of the foot and ankle during dorsiflexion, potentially leading to improper force absorption and distribution. This can have a domino effect, causing issues not only in the foot and ankle but also in the knees, hips, and even the shoulders and neck over time.
To address flat feet and improve dorsiflexion, exercises such as squats and lunges can be beneficial. Training barefoot can also help, as it allows the ankle to dorsiflex naturally without the restriction of shoes. Additionally, seeking professional advice from a physical therapist or experienced coach can provide personalised guidance to improve dorsiflexion and address any underlying issues related to tight calves or flat feet.

Dorsiflexion exercises include squats, lunges, and stretching the calves
Dorsiflexion is the backward bending and contracting of the foot at the ankle. This movement allows the foot to absorb the shock of landing and helps to spring the individual forward into the next stride. It is a relatively simple movement but plays a significant role in running technique and can cause complex problems for athletes.
Poor dorsiflexion can lead to a "loose" or "floppy" foot due to relaxation at the ankle joint, resulting in striking the ground through the toes. This can cause injuries such as shin splints and runner's knee. It can also reduce the ability to utilise power from the posterior chain muscles.
Limited dorsiflexion can be caused by tight calves, flat feet, or an impaired ankle. To improve dorsiflexion, it is important to stretch the calves to help loosen up and stretch the larger muscles that affect ankle movement. Helpful stretches include the gastrocnemius stretch, soleus muscle stretch, and stretching on a step.
In addition to these exercises, it is beneficial to perform dorsiflexion strength exercises such as isometrics or full-range-of-motion variations. These can be done for 2-4 sets of 5-15 second holds, building up to 100% effort, or 2-4 sets of 15-25 repetitions.
