Definition: Pronation describes the motion of rotating towards the prone position (having the front or ventral surface facing downward). In kinesiology, this term often describe the rotation of the wrist and forearm so that the palm is turned in and downward. However, pronation is perhaps most commonly used to describes a slight inward rolling motion the foot makes during a normal walking or running stride. The foot (and ankle) rolls slightly inward to accomodate movement. Some people, however, over-pronate and roll more than normal. With over-pronation, the arch of the foot flattens and causes excessive stress and pressure on the soft tissues of the foot. Over-pronation is more common in those with flat feet, and can lead to foot aches and pain, such as plantar fasciitis, Shin Splints and Knee Pain.
Wearing the proper footwear, using shoe inserts / insoles, or orthotics can help reduce over-pronation.
Also Known As: over-pronation, flatfeet
