What joints are involved in pronation and supination?
Pronation and supination are movements that occur at the proximal radioulnar joint. The head of the radius is discoid and fits with the radial neck within the circular annular ligament, that attaches the proximal radius to the ulna.
What is supination of ankle?
Supination of the foot occurs when your weight rolls onto the outer edges of your feet. Another name for supination is underpronation. In a normal stride, your foot should roll inward a bit (pronate) so that your weight is on the ball of your foot. Then you push off the big toe.
How does pronation and supination of the ankle contribute to injuries?
People who pronate excessively roll their foot inward, causing the outer part of the heel to make contact with the ground and the feet to flatten too much. Those who supinate do not roll their foot inward enough. This puts a strain on the ankle and can cause the ankle to roll outward, which leads to injury.
What is supination and pronation of foot?
Both terms involve your gait and how your weight is distributed as you walk or run. Supination means that when you walk, your weight tends to be more on the outside of your foot. Pronation means that when you walk, your weight tends to be more on the inside of your foot.
What muscles pronate the ankle?
The muscles active during pronation are the anterior tibialis, extensor digitorum longus, and the extensor hallucis longus, all of which are supinators of the foot.

What joint does pronation happen at?
subtalar joint
Pronation and supination are the triplane motions in the subtalar joint, the so-called universal joint of the lower extremity. In weight bearing, pronation occurs at initial contact through the loading response during gait.
What type of joint is the ankle joint?
hinged synovial joint
Overview. The ankle joint is a hinged synovial joint with primarily up-and-down movement (plantarflexion and dorsiflexion). However, when the range of motion of the ankle and subtalar joints (talocalcaneal and talocalcaneonavicular) is taken together, the complex functions as a universal joint (see the image below).
Why do I pronate?
Overpronation is generally caused by flat, very flexible feet. Sometimes, people are born with flat feet. However, there are also conditions and situations that can increase a person’s chances of developing flat feet or weakened arches, which can lead to overpronation.
What are the differences between pronation and supination?
The differences between pronation and supination are that pronation is the term for the inward roll of the foot in motion and supination refers to its opposite, the outward roll of the moving foot.
Can you reduce pronation?
Orthotics support your arch and can improve the way your foot hits the ground. They may ease the pain you are experiencing and reduce your pronation during activities. Prescription orthotics are custom made for you using the information from your gait analysis.
What are the different causes of pronation?
Causes of Overpronation Genetics. For some people, overpronation appears to be genetic and is present from childhood. Flat Feet. Individuals who have very flat feet or a collapsed arch tend to overpronate. Wear and Tear. Unsupportive or Worn Footwear.
Can over pronation be corrected by surgery?
Corrective surgery is the most common and most frequently applied ways to correct over pronation. It often involves different ways of re aligning the bone mass in the foot to be in the right order so as to ensure proper pronation. It is done by identifying the state of arrangement the bones in the foot before surgery.
