The ankle share is comprised of two long bones — the tibia and the fibula — and also underlying tarsal bones. There are seven tarsal bones in every foot. In total, the ankle permits the foot to move in six various ways: dorsiflexion, plantarflexion, inversion, eversion, and also medial and also lateral rotation.

You are watching: Turning the sole of the foot medially

Flexion and also extension in ~ the ankle are described as dorsiflexion and plantarflexion, dong (Figure 2). “Dorsi” describes the peak of the foot, when “plantar” describes the bottom the the foot. The hatchet “flexion” is integrated to suggest movement upwards (dorsiflex) or downwards (plantarflex). Dorsiflexion occurs once you background the forward portion of the foot up (rocking ago on her heels with the balls of your feet elevated). Plantarflexion occurs when you press the forward portion of the foot down (raising her heels off the ground together you walk up on the balls of her feet).

Dorsiflexion is a normal part of squatting down towards the ground, when plantarflexion is a normal component of stand up. Essentially, any ground-based exercise has both dorsiflexion and also plantarflexion as an facet of movement.


Figure 2: Flexion and also extension in ~ the fishing eye are referred to as dorsiflexion and plantarflexion.


The ankle also facilitates side-to-side motions of the foot known as inversion (rolling the sole of the foot to face medially) and eversion (rolling the sole of the foot to confront laterally), as illustrated in number 3. In to compare these motions to the movements of the wristand hand, we deserve to see the supination and pronation are analogous movements.

Rotation in ~ the ankle provides a minimal range the motion focused on the heel. If friend sit down, save your hoe on the ground, and slightly background the round of the foot turn off the floor (dorsiflexion), you deserve to pivot the foot medially (internal rotation) and also laterally (external rotation), as shown in figure 4. This is a tiny range of motion, together the bony framework of the ankle limits excursion in both directions. The largest rotation that the foot wake up via the i know well joint. You deserve to compare the distinction in the varieties of motion of this two different joints through standing and performing internal and also external rotation to demonstrate hip mobility, climate sitting and also observing fish eye mobility as defined above.
