Biomechanics for Abnormal Pronation

Our bodies benefit from normal foot biomechanics, distribution of force, because the way we place our feet on the ground affects the limbs above them. Biomechanical foot abnormalities such as abnormal pronation can create muscle imbalances and foot problems.

Pronation

• Pronation, a normal movement pattern in your feet, happens when you walk and the insides of your feet -- your arches -- momentarily connect with the ground as you put your foot down. An important action for the athlete in particular, it helps absorb the impact of ground contact, providing it remains within acceptable range.

Abnormal Pronation

• Abnormal pronation happens when the joints in your ankles or feet have excessive motion, hypermobile, or have restricted motion, hypomobile. Because of the altered joint mobility, abnormal stress and breakdown of muscle and connective can occur, leading to conditions such as shin splints, knee pain, bunions, heel spurs and Achilles tendinitis.

Prevention/Solution

• Abnormal pronation can be congenital or happen over time because of tight Achilles tendons or pelvic or muscle imbalances. Individuals with the condition should consider using foot orthotics in shoes to correct it. Consult with your doctor to have them custom-designed to your foot and shoes.
