The tibialis anterior and tibialis posterior muscles are primarily assessed when the foot is placed in inversion. Tibialis anterior helps with dorsiflexion and inversion, while tibialis posterior assists with inversion and plantar flexion of the foot.
Inversion and eversion of the foot occur at the subtalar joint, which is formed by the articulation of the talus bone with the calcaneus bone. These movements involve tilting the sole of the foot towards the midline (inversion) or away from the midline (eversion).
The movement that rotates the sole of the foot medially is called "inversion." During inversion, the foot tilts inward, causing the sole to face towards the midline of the body. This movement primarily involves the subtalar joint and is facilitated by muscles such as the tibialis posterior and tibialis anterior. Inversion is important for maintaining balance and stability during various activities.
Inversion of the foot turns the sole of the foot laterally, meaning the sole of the foot is facing outward. This movement involves the foot rolling towards the outer side.
A thick, flat, deep muscle in the posterior compartment of the lower leg. The tibialis posterior has extensive origins on the posterior, proximal surface of the tibia, fibula, and interosseus membrane. Its insertion is on the tarsal and metatarsal bones via a tendon that passes behind the medial malleolus and under the arch of the foot. Its primary actions are plantar flexion and inversion. It also helps to stabilize the longitudinal arch, especially during skating.
The subtalar joint is used when turning the sole of the foot medially. This joint is located between the talus bone and the calcaneus bone in the foot, and it allows for inversion and eversion movements.

Inversion is often associated with the ankle; spmetimess called supination. And there several muscles in involved. The muscle of inversion of the foot is mostly the tibilialis anterior.
The tibialis anterior muscle inserts onto the base of the first metatarsal and the medial cuneiform bone. It is responsible for dorsiflexion of the foot and inversion of the ankle.
There are several types of exercises that can be done to correct inversion. Orthotics are also used to make walking easier and more comfortable.
In a sport context, when the foot is inverted, a football player can curl the ball with the inside of his of his foot. Another example is when a basketball player jumps for a rebound. As they jump, their foot is inverted to make them jump higher.

Inversion of the foot is to face the sole of your foot inward toward your midline and eversion is to face the sole of your foot away.
Inversion and eversion of the foot occur at the subtalar joint, which is formed by the articulation of the talus bone with the calcaneus bone. These movements involve tilting the sole of the foot towards the midline (inversion) or away from the midline (eversion).
Tibialis anterior, Peroneus Longus and Tibialis Posterior. These are the " stirrup" muscles around the ankle and foot to stabilize the ankle in inversion and eversion actions. Thanks, Bing
In medicine, evertion means : turning something inside out, for example eversion of the uterus is when the uterine inner-lining comes to appear externally out of the vagina . Foot evertion : a special movement of the ankle joint, where the sole of the foot is turned outwards.. Inversion being the opposite meaning..
