The Truth Regarding Over-Pronation

Overview

Overpronation is the most common abnormality found in the foot, and for this reason, is the most studied. The term that most people attribute to overpronation is ?flat feet.? Pronation is the rolling in of the foot and the collapse of the arch. Every person pronates to some extent and this is a necessary moment in the normal walking cycle as it allows the forefoot to make complete contact with the ground. A foot that overpronates acts like a loose bag of bones during the walking cycle. This makes this type of foot very flexible but inefficient. The foot has to work much harder to propel the body, fatiguing easily and placing mechanical stresses on the lower body. We like to use the analogy of digging a hole in the dirt. Overpronating feet are like using a broom to dig the hole. It won?t break down quickly, but you will be digging for a very long time, or until eventually wear and tear will take effect. Wouldn?t you rather have a shovel to work with. This is in essence what an orthotic can do for your feet. This is why orthotics have become an evidence based treatment for so many foot ailments, as they can effectively manage overpronation.Overpronation is when a person pronates too much and for too long. This places excess stress on the tendons and ligaments in the foot and ankle.Over Pronation

Causes

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.

Symptoms

In addition to problems overpronation causes in the feet, it can also create issues in the calf muscles and lower legs. The calf muscles, which attach to the heel via the Achilles tendon, can become twisted and irritated as a result of the heel rolling excessively toward the midline of the body. Over time this can lead to inflexibility of the calf muscles and the Achilles tendon, which will likely lead to another common problem in the foot and ankle complex, the inability to dorsiflex. As such, overpronation is intrinsically linked to the inability to dorsiflex.

Diagnosis

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.Over Pronation

Non Surgical Treatment

Mild cases of Overpronation may be controlled or corrected with a supportive shoe that offers medial support to the foot along with a strong heel counter to control excessive motion at the heel starting with heel strike. In mild cases with no abnormal mechanical pressures, an over the counter orthotic with heel cup and longitudinal or medial arch support to keep the foot from progressing past neutral may help to realign the foot. A Custom foot orthotic with heel cup and longitudinal arch support to help correct position of the foot as it moves through motion. Heel wedges may also assist in correcting motion.

Prevention

Pronation forces us to bear most of our weight on the inner border of our feet. Custom-made orthotics gently redistributes the weight so that the entire foot bears its normal share of weight with each step we take. The foot will not twist out at the ankle, but will strike the ground normally when the orthotics is used. This action of the custom-made orthotics will help to prevent shin splints, ankle sprains, knee and hip pain, lower back pain, nerve entrapments, tendonitis, muscle aches, bunions, generalized fatigue, hammer toes, and calluses.
