As with the "normal pronation" sequence, the outside of the heel makes the initial ground contact. However, the foot rolls inward more than the ideal fifteen percent, which is called "overpronation."
This means the foot and ankle have problems stabilizing the body, and shock isn't absorbed as efficiently. At the end of the gait cycle, the front of the foot pushes off the ground using mainly the
big toe and second toe, which then must do all the work.
For those not familiar with the term pronation, you might be familiar with terms related to shoes and pronation such as ?motion control?, ?stability,? and ?neutral cushioned.? The terms motion
control and stability are typically associated with the word ?over-pronation? or a foot that is supposedly pronating too much and needs correction. According to the running shoe industry,
?over-pronation? is a biomechanical affliction evident when the foot and or ankle rolls inward past the vertical line created by your leg when standing.
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.
When sitting, an over-pronating foot appears quite normal, i.e. showing a normal arch with room under the underside of the foot. The moment you get up and put weight on your feet the situation
changes: the arches lower and the ankle slightly turns inwards. When you walk or run more weight is placed on the feet compared to standing and over-pronation will become more evident. When walking
barefoot on tiles or timber floors over-pronation is more visible, compared to walking on carpet or grass.
Non Surgical Treatment
Podiatrists are trained to effectively detect and management over-pronation. You can get a referral to a podiatrist from your GP if you are presenting with the pain typical of over-pronation, or you
can seek private podiatric care in anyone of several registered and accredited practices across the country. Your podiatrist will examine your foot and its shape to determine whether or not
over-pronation is the cause of your pain. If your podiatrist determines that it is a problem with arch support that is giving you trouble, then they can effectively remedy that lack of support with
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.
