Pronation is the natural act of the body spreading the impact of walking, jogging or running throughout the foot evenly. As the foot strikes the ground, the ankle naturally rolls inward absorbing the
shock of the ground and mobilizing to the terrain. Overpronation is when the ankle of the foot rolls in past its normal 15? of inward rotation. The cause of this could be many things such as foot
type, biomechanics, or compensation strategies. People with flat feet often, although not always, overpronate.
Unless there is a severe, acute injury, overpronation develops as a gradual biomechanical distortion. Several factors contribute to developing overpronation, including tibialis posterior weakness,
ligament weakness, excess weight, pes planus (flat foot), genu valgum (knock knees), subtalar eversion, or other biomechanical distortions in the foot or ankle. Tibialis posterior weakness is one of
the primary factors leading to overpronation. Pronation primarily is controlled by the architecture of the foot and eccentric activation of the tibialis posterior. If the tibialis posterior is weak,
the muscle cannot adequately slow the natural pronation cycle.
Over-pronation is a condition where the arch flattens out which makes the feet roll inward while walking. This condition is also known as flat feet. It imposes extreme additional stresses on the
plantar fascia, a fibrous band of tissue which connects the heel to the forefoot. Over-pronation makes walking a painful experience because of the additional strain on the calves, heel and/or back.
Treatment for over-pronation involves the use of specially-made orthotics which offers arch support and medial rear foot posting as corrective measures.
When you overpronate your foot rolls inwards causing the lower leg to rotate inwards too. It's thought that this increases stress on the soft tissues of the lower leg causing pain and inflammation,
or more commonly known as shin splints.
Non Surgical Treatment
There are exercises that you can do to help deal with the effects and treat the cause. Obviously you can opt for an insert into your shoe either by way of your sports shop or go see a podiatrist.
Like anything in your body that is not working correctly; you will have to manage your condition. Don't put off dealing with the problem as it will manifest associated issues along the alignment and
as far up as your neck. If it's mild pronantion, I suggest running barefoot. If you can't do this then don't wear shoes at all at home or in the office as much as possible. Give your calf muscles a
huge stretch everyday as these with the ligaments from the foot up to the muscle get tight and are linked to your pain. Loosen your calf muscles as much as possible. Great exercise is to sit barefoot
with a marble on the floor in front of you. Grab the marble with your toes and try to hold it tight in the middle of the base of your foot. Ping pong balls and even golf balls work. Do this each
night and combined with calf stretches you'll start to correct the muscle alignment gradually in the foot. Put more attention into massaging your feet, standing with a good posture, stretching your
feet, ankles and calf muscles. Lastly, if you are fat this will not help at all. You must lose weight swimming, cycling and eradicating sugar and fat from your diet. The added strain on the foot by
being a fat body compounds the problems and inhibits corrective results that you are after.
Hyperpronation can only be properly corrected by internally stabilizing the ankle bone on the hindfoot bones. Several options are available. Extra-Osseous TaloTarsal Stabilization (EOTTS) There are
two types of EOTTS procedures. Both are minimally invasive with no cutting or screwing into bone, and therefore have relatively short recovery times. Both are fully reversible should complications
arise, such as intolerance to the correction or prolonged pain. However, the risks/benefits and potential candidates vary. Subtalar Arthroereisis. An implant is pushed into the foot to block the
excessive motion of the ankle bone. Generally only used in pediatric patients and in combination with other procedures, such as tendon lengthening. Reported removal rates vary from 38% - 100%,
depending on manufacturer. HyProCure Implant. A stent is placed into a naturally occurring space between the ankle bone and the heel bone/midfoot bone. The stent realigns the surfaces of the bones,
allowing normal joint function. Generally tolerated in both pediatric and adult patients, with or without adjunct soft tissue procedures. Reported removal rates, published in scientific journals vary
