Which movements are produced at the subtalar joint?

The subtalar joint is primarily responsible for facilitating movements that allow for the complex actions of the foot, particularly those necessary for adaptation to different surfaces and maintaining balance during various activities. The main movements produced at the subtalar joint are inversion and eversion, which refer to the tilting of the sole of the foot inward and outward, respectively.

Inversion occurs when the medial aspect of the foot is raised, which brings the foot towards the midline of the body, while eversion involves the lateral aspect of the foot being lifted, moving it away from the midline. These movements are crucial for activities such as walking on uneven terrain and adjusting foot position for proper weight distribution.

While the choice includes dorsiflexion and plantar flexion, these movements are primarily associated with the ankle joint (tibiotalar joint) rather than the subtalar joint. Dorsiflexion involves lifting the front of the foot towards the shin, and plantar flexion refers to pointing the toes downward, both pivotal for overall foot function but not directly produced at the subtalar joint.

Therefore, the correct answer encompasses the key movements that truly originate at the subtalar joint, identifying inversion and eversion as the primary actions to understand its functional role in lower limb
