| Description:
In simple term, pronation is the flattening out of the arch when the foot strikes the ground. Normally, the foot will pronate to absorb shock when the heel hits the ground, and to assist in balance during mid-stance. The ankle will 'tip' towards the inside.
Problems it causes:
With excessive pronation/ over pronation, the arch flattens, collapses, and soft tissues stretch. This causes the joint surfaces to function at unnatural angles to each other. When this happens, joints that should be stable now become very loose and flexible.
At first, excess pronation may cause fatigue. As the problem gets worse, strain on the muscles, tendons, and ligaments of the foot and lower leg can cause permanent problems and deformities. The more a person pronates the more pressure they apply on the medial side of the foot. This leads to more foot deformities and callous formation. |
