What Causes Over-Pronation

Posted on

Overview

Over Pronation (Flat Feet) refers to the biomechanical shock-absorbing motion of the ankle, foot and lower leg. It is the natural inward flexing motion of the lower leg and ankle. Standing, walking, and running cause the ankle joint to pronate which in turn helps the body to absorb shock and allows it to control balance. An ankle joint that is too flexible causes more pronation than desired. This common condition is called Over- Pronation (sometimes referred to as “Flat Feet”). This foot condition places an extreme degree of strain on various connective tissues of the ankle, foot, and knee. If this condition is not addressed foot pain and toe deformities such as bunions and hammer toes (just to name a couple) may develop. Hip and lower back pain may also be residual results from this condition.Over-Pronation

Causes

There has been some speculation as to whether arch height has an effect on pronation. After conducting a study at the Rose-Hulman Institute of Technology, Maggie Boozer suggests that people with higher arches tend to pronate to a greater degree. However, the generally accepted view by professionals is that the most pronation is present in those with lower arch heights. To complicate matters, one study done by Hylton Menz at the University of Western Sydney-Macarthur suggests that the methods for measuring arch height and determining whether someone is ?flat-footed? or ?high-arched? are unreliable. He says, ?For this reason, studies investigating the relationship between static arch height motion of the rearfoot have consistently found that such a classification system is a poor predictor of dynamic rearfoot function.

Symptoms

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.

Diagnosis

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.Overpronation

Non Surgical Treatment

Side Step with Opposite Reach. This exercise is designed to load the “bungee cord system” of the gluteal muscle and its opposite, latissimus dorsi muscle to keep the foot from overpronating. Because the opposite arm swings across the front leg when walking, this exercise creates tension in the muscles all the way from the front foot, across the back of the hips and back, to the fingers of the opposite hand. Movement Directions. Stand with left foot on top of the dome of the BT. (Note: For added balance, the right foot can tap on the ground, if needed). Reach right leg out to the side of the BT, and tap the ground while squatting down on the left side and reaching right arm across the left knee. Push down with left big toe while squatting. This activates the arch of the left foot and strengthens all the stabilizing muscles on the left side of the lower body. Return to starting position. Perform 8 to 10 repetitions on each leg.

Surgical Treatment

Depending on the severity of your condition, your surgeon may recommend one or more treatment options. Ultimately, however, it’s YOUR decision as to which makes the most sense to you. There are many resources available online and elsewhere for you to research the various options and make an informed decision.
