Pronation / Rolling-in Ankles

Home > Disorders & Symptoms > Pronation / Rolling-in Ankles

Pronation is when the ankles roll inwards.

Pronation is usually caused by a muscle weakness in the ankle. Underlying foot conditions and deformities also affect pronation - as the muscles, ligaments and bones move out from the normal alignment, it affects the whole ankle and leg structure.

The common perception is that people have pronation when they have flat feet, however a person who has high arches can also have pronation.

A person can also have two different degrees of pronation between the left and right side. This should also be visible both from looking at the feet while standing and also from the pressure map. Having two different degrees of pronation can lead to an unbalanced condition and add more symptoms like sore back and sore joints.

Pronation is visible when the person is standing on a hard surface, in three ways:

• The ligament from the heel up to the Achilles tendon is curved, where it should be straight.
• The outline of the foot around the side support area is curved, where it should be straight.
• The inside ankle bones are sticking out, and the whole foot structure is rolling inwards.

From Pedikom pressure map, pronation is visible when the pressure area around the side support area does not touch the outline of the foot - there is a lack of pressure. This means the side support pressure has shifted towards the inside of the foot . Also, the highest pressure areas (white/blue) on the heel is towards the inside of the heel and the bunion area on the metatarsal.

Treatment: As the built in modules in the patients Pedikom Orthotics pushes the bones, joints, ligaments and muscles back into the correct/normal alignment, and reverse the patients base foot problem, as well as providing support, the orthotics will gradually decrease pronation.
