Overpronation is a term which is used more and more frequently by runners and exercisers these days, but what is overpronation and is it bad? Overpronation is excessive pronation of the feet when
walking and running, and it can place people at risk of developing foot problems. Knowing the degree to which you pronate is important in order to select the correct footwear and exercise shoes. If
you pronate excessively you could be placing an excessive strain on your feet, however overpronators can also place an excessive strain on the ankles, legs, knees, hips and lower back. Runners often
claim to be an overpronator or even an underpronator or supinator. These terms may very well be viewed in a negative light when they really are not a problem at all. On the other hand people may be
overpronators and not even know about it and could be at a high risk of developing a musculoskeletal problem.
You do not have to be a runner or athlete to suffer from overpronation. Flat feet can be inherited, and many people suffer from pain on a day-to-day basis. Flat feet can also be traumatic in nature
and result from tendon damage over time. Wearing shoes that do not offer enough arch support can also contribute to overpronation.
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
Studies have shown that the most effective way to dexrease a high Q angle and lower the biomechanical stresses on the knee joint is to prevent excessive pronation with custom-maflexible orthotics.
One study found that using soft corrective orthotics was more effective in reduknee pain than a traditional exercise program. A more recent study showed that Q angle asymmetries, secondary to
excessive pronation affecting knee alignment, can be effectivecontrolled or corrected utilizing custom-made, flexible orthotics. Another project involving meof a running club determined that 75% of
those using orthotics eliminated or greatly reduced pain in the feet, ankles, shins, knees and hips
Calcaneal "Slide" (Sliding Calcaneal Osteotomy) A wedge is cut into the heel bone (calcaneus) and a fixation device (screws, plate) is used to hold the bone in its new position. This is an aggressive
option with a prolonged period of non-weightbearing, long recovery times and many potential complications. However, it can and has provided for successful patient outcomes.
