The direction of terms are opposite to those in the foot because of embryological rotation of the limbs in opposite directions. [10] Palmarflexion is flexion of the wrist towards the palm and ventral side of forearm. [30] Dorsiflexion is hyperextension of the wrist joint, towards the dorsal side of forearm. [30]
Pronation is a natural movement of the foot that occurs during foot landing while running or walking. Composed of three cardinal plane components: subtalar eversion, ankle dorsiflexion, and forefoot abduction, [1] [2] these three distinct motions of the foot occur simultaneously during the pronation phase.

A patient recovering from surgery to treat foot drop, with limited plantar and dorsiflexion.. Foot drop is a gait abnormality in which the dropping of the forefoot happens out of weakness, irritation or damage to the deep fibular nerve (deep peroneal), including the sciatic nerve, or paralysis of the muscles in the anterior portion of the lower leg.
For the foot, pronation will cause the sole of the foot to face more laterally than when standing in the anatomical position. Pronation of the foot is a compound movement that combines abduction, eversion, and dorsiflexion. Regarding posture, a pronated foot is one in which the heel bone angles inward and the arch tends to collapse.
The movements of tibialis anterior are dorsiflexion and inversion of the ankle. However, actions of tibialis anterior are dependent on whether the foot is weight bearing or not (closed or open kinetic chain). When the foot is on the ground, the muscle helps to balance the leg and talus on the other tarsal bones so that the leg is kept vertical ...
The ankle dorsiflexion is a result of the tibia moving forward over the foot and is facilitated by eccentric control provided by the soleus. [ 5 ] [ 11 ] Concurrently, the knee reaches full extension and as the heel rises off the ground the ankle begins to plantar flex.
While all three muscles move the sole of the foot outward, away from the midline of the body , the longus and brevis extend the foot downward away from the body (plantar flexion), whereas the tertius muscle pulls the foot upward toward the body (dorsiflexion).
This foot type is typically characterized with cavus—the elevation of the longitudinal plantar arch (e.g., the bottom arch of a foot), plantar flexion of the foot, forefoot pronation, hindfoot varus, or forefoot adduction. A high arch is the opposite of a flat foot and is somewhat less common.
