Overpronation
Overpronation is a biomechanical condition characterized by the excessive inward rolling of the foot during movement, particularly during walking or running. It occurs when the joint below the ankle (the subtalar joint) is hypermobile. The result is that the foot falls inward when it is weight bearing, causing it to lose its normal arch contour and stability. This typically results in increased pressure on the inner side of the foot, as well as increased strain on the muscles, ligaments, and tendons of the whole leg. It commonly leads to the development of overuse injuries such as plantar fasciitis, Achilles tendinopathy, and shin splints.
At The Court Clinic, we typically identify overpronation as having one of two overarching causes. Inherent overpronation is typically present since birth, affects both feet equally, and is rooted in a genetic predisposition to hyperflexibility in the midfoot. In contrast, acquired overpronation occurs as a result of previous ligament damage to the outside of the ankle, typically as a result of ankle sprain. This permanent ligament damage causes the midfoot to roll inward, creating the overpronation effect.
Regardless of the cause, the best line of treatment in the first instance for overpronation is the creation of customised insoles. At The Court Clinic, we will use our assessment to determine the exact level of support required to eliminate the overpronation and, in doing so, optimise the function of your foot. Once the success of that approach has been confirmed, the best long term solution is to then create fully custom-made orthotics. This provides a permanent solution to the problem of overpronation and protects against the potential side-effects which include osteoarthritis, pain and foot deformity.
