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.

Sinus tarsi syndrome is the clinical disorder of pain and tenderness in the sinus tarsi, which is a lateral tunnel in the foot at the junction of the hindfoot and the midfoot, between the ankle and the heel. [1] [2] Most of the time, sinus tarsi syndrome onsets after ankle sprains, however there can be other causes. [3]
Pronation, neutral, and supination placements of the right ankle. The ankle and foot naturally pronate and supinate by about 5 degrees while walking or running. The red arrows indicate excessive pronation. In general, overuse injuries are the result of repetitive impact between the foot and the ground. With improper running form, the force of ...
Pes cavus can occur from four primary causes: neurological conditions, trauma, undertreated clubfoot, or idiopathic with other underlining conditions. [9]Bilateral presentation (i.e., in both feet) often occurs due to a hereditary or congenital source, whereas a unilateral presentation (i.e., in one foot) is often the result of trauma.
This is a test of upper motor neuron disease. [citation needed]If a forearm pronates, with or without downward motion, then the person is said to have pronator drift on that side reflecting a contralateral pyramidal tract lesion.
Pronator teres syndrome (also known as pronator syndrome) is compression of the median nerve between the two heads of the pronator teres muscle. [13] The Pronator teres test is an indication of the syndrome—the patient reports pain when attempting to pronate the forearm against resistance while extending the elbow simultaneously. The ...
Focal neurological deficits may be caused by a variety of medical conditions such as head trauma, [1] tumors or stroke; or by various diseases such as meningitis or encephalitis or as a side effect of certain medications such as those used in anesthesia. [2] Neurological soft signs are a group of non-focal neurologic signs. [3]
This is not a true collapsed arch, as the medial longitudinal arch is still present and the windlass mechanism still operates; this presentation is actually due to excessive pronation of the foot (rolling inwards), although the term 'flat foot' is still applicable as it is a somewhat generic term. Muscular training of the feet is helpful and ...
