Everyone pronates! Contrary to popular misconception it is healthy and normal. The problem begins when one or both of our feet pronate too much. When the arches flex too far inward or stay collapsed
for too long pronation is considered excessive. We call this overpronation. Overpronation is by far the most common foot type. Pronation is not linked one-to-one with low arches. Although pronation
lowers the arches, this does not mean that only those with low arches overpronate. People with high arches can also overpronate! Some of us have always overpronated, for others overpronation develops
with age, weight gain, regular standing work or intensive exercise.
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.
Overpronation can be a contributing factor in other lower extremity disorders, such as foot pain, plantar fasciitis, ankle injuries, medial tibial stress syndrome (shin splints), periostitis, stress
fractures and myofascial trigger points. Overpronation increases the degree of internal tibial rotation, thereby contributing to various knee disorders such as meniscal injury or ligament sprains.
The effects of the postural deviation are exaggerated in athletes due to the increase in foot strikes while running and the greater impact load experienced. When running, three to four times the body
weight is experienced with each foot strike.2 If overpronation exists, the shock force is not adequately absorbed by the foot and is transmitted further up the kinetic chain.
Do the wet foot test. Get your feet wet and walk along a paved surface or sand and look at the footprints you leave. If you have neutral feet you will see a print of the heel with a thin strip
connecting to your forefoot, but if you're overpronating your foot print will look a bit like a giant blob with toes.
Non Surgical Treatment
Anti-Pronation Insoles provide a unique foot support system that aligns the lower body. The major cause of foot and leg pain is over pronation (rolling over of the feet) which causes excessive
pressure on the muscles, ligaments and bones of the lower body. Running insoles treat the underlying cause of over pronation and prevent future occurrences of the associated foot or leg condition. A
project conducted at the NIKE Sport Research Laboratory studied the effects of orthotics on rear foot movement in running. Nine well-trained runners who wore orthotics were chosen as subjects. The
results of the study indicated that orthotics reduced rear foot movement by roughly one degree or approximately nine percent of the amount found in runners not using orthotics. The average reduction
of the maximum velocity of pronation was fifteen percent. Thus this study indicates that orthotics and insoles control over pronation which will treat and prevent many sporting injuries.
Subtalar Arthroereisis. Primary benefit is that yje surgery is minimally invasive and fully reversible. the primary risk is a high chance of device displacement, generally not tolerated in
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.
