[11] When the legs are splayed at the hip, such as when doing a star jump or doing a split, the legs are abducted at the hip. Regularly stretching the legs, especially after workouts, can help increase flexibility, range of motion and blood flow in painful areas.

Backward bending of the foot Extension Straightening of a flexed limb Fascia Fibrous membrane separating and enveloping muscles. Doctors can detect this birth defect by doing a physical examination and taking various measurements of the legs. Medial plantar muscles act upon the great toe, or hallux.

Overpronation can also contribute to injuries, including runners knee, Underpronation (excess supination) is the, Runners with high arches and tight Achilles tendons tend to be underpronators/supinators. The main actions of the ankle are plantarflexion, dorsiflexion, The subtalar joint (articulation between the talus and calcaneus) allows inversion and eversion of the foot.

[4], Cutaneous innervation of the dorsum is by the superficial and deep peroneal/fibular nerves. These problems begin in the arches of the feet and heels but often spread up to the calves, ankles, knees and even back. Attachments: Originates from the tibia and transitions into a tendon, passes into the foot, splits into four, and attaches to the toes.

Like the fingers, the toes have flexor and extensor muscles that power their movement and play a large role in balance. In terms of mobility, the Achilles tendon is one of the most important structures in the leg and foot. The tendons connect anterior/dorsiflexor compartment muscles of the leg to the foot bones. Important muscle to examine because its function is often maintained in even very severe brachial plexus injuries where it can act as a donor nerve for nerve transfer procedures.
