It is estimated that around 80% of the population suffer from excessive pronation. This condition is common in all types of people from children to the elderly and from top athletes to people with a sedentary lifestyle. The feet become misaligned and combined with poor posture roll inwards to gain ground contact, the arches become flattened producing the condition known as excessive pronation. When the feet are excessively pronated a combination of poor posture and diminished shock absorption results in some areas of the feet being subjected to excessive stress and pressure. This can lead to various conditions including knee and back problems, as well as foot problems and deformities.
Over-pronation has different causes. Obesity, pregnancy, age or repetitive pounding on a hard surface can weaken the arch leading to over-pronation. Over-pronation is also very common with athletes, especially runners and most of them nowadays use orthotics inside their shoes. Over-pronation affects millions of people and contributes to a range of common complaints including sore, aching feet, ball of foot pain, heel Pain, achilles tendonitis, bunions, shin pain, tired, aching legs, knee pain and lower back pain. The most effective treatment solution for over-pronation is wearing an orthotic shoe insert. Orthotics correct over-pronation, thereby providing natural, lasting pain relief from many common biomechanical complaints.
Common conditions seen with overpronation include heel pain or plantar fasciitis, achilles tendonopathy, hallus valgus and or bunions, patellofemoral pain syndrome, Iliotibial band pain syndrome, low back pain, shin splints, stress fractures in the foot or lower leg.
If you have flat feet or low arches, chances are you overpronate. Although not always the case, the lower your arches the greater the overpronate. Stand on a hard surface (in front of a mirror if you need to) and look at your feet, flat feet or low arches are easy to spot. If your feet look flatter than a pancake, have a look at your ankles and see if they seem collapsed or straight. If they are, you're overpronating.
Non Surgical Treatment
If a young child is diagnosed with overpronation braces and custom orthotics can be, conjunction with strengthening and stretching exercises, to realign the bones of the foot. These treatments may have to continue until the child has stopped growing, and orthotics may need to be worn for life in order to prevent the foot reverting to an overpronated state. Wearing shoes that properly support the foot, particularly the arch, is one of the most effective treatments for overpronation. Custom-made orthotic inserts can also be very beneficial. They too support the arch and distribute body weight correctly throughout the foot. Motion-control shoes that prohibit pronation can be worn, so may be useful for those with severe overpronation. One good treatment is to walk barefoot as often as possible. Not relying on shoes to support the arch will encourage proper muscle use. Practicing yoga can help to correct poor posture and teach you how to stand with your weight balanced evenly across the whole foot.
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 from 1%-6%.
