The Treatments And Causes Of Overpronation Of The Foot
Overview


Flat feet or foot pronation is common and often people with flat feet never have any problems. However, it can lead to over pronation when walking and running, this is a biomechanical problem when the arch of the foot collapses during weight bearing. This can have a knock on effect up the leg causing the knee to roll inwards, the hip and pelvis to rotate and even torsion in the lower back. Subsequently, over pronation can lead to lots of different injuries from plantar fasciitis to lower back pain. Therefore, assessment and correction of over pronation is a crucial part of any rehabilitation program. This can be done with orthotics.Over Pronation


Causes


There are many possible causes for overpronation, but researchers have not yet determined one underlying cause. Hintermann states, Compensatory overpronation may occur for anatomical reasons, such as a tibia vara of 10 degrees or more, forefoot varus, leg length discrepancy, ligamentous laxity, or because of muscular weakness or tightness in the gastrocnemius and soleus muscles. Pronation can be influenced by sources outside of the body as well. Shoes have been shown to significantly influence pronation. Hintermann states that the same person can have different amounts of pronation just by using different running shoes. It is easily possible that the maximal ankle joint eversion movement is 31 degrees for one and 12 degrees for another running shoe.


Symptoms


People with overpronation may suffer from pain in the knees, hips, and low back. Overpronation itself does not necessarily cause any other symptoms but is a contributing factor of many foot conditions such as Plantar Facsiitis, Heel Spur Syndrome, Posterior Tibialis Tendon Rupture or Tendonitis, Hallux Valgus, Bunion Deformities, Metatarsalgia, Hallux Limitus or Hallux Rigidus, Hammer Toes, and Morton?s Neuroma.


Diagnosis


One of the easiest ways to determine if you overpronate is to look at the bottom of your shoes. Overpronation causes disproportionate wear on the inner side of the shoe. Another way to tell if you might overpronate is to have someone look at the back of your legs and feet, while you are standing. The Achilles tendon runs from the calf muscle to the heel bone, and is visible at the back of the ankle. Normally it runs in a straight line down to the heel. An indication of overpronation is if the tendon is angled to the outside of the foot, and the bone on the inner ankle appears to be more prominent than the outer anklebone. There might also be a bulge visible on the inside of the foot when standing normally. A third home diagnostic test is called the ?wet test?. Wet your foot and stand on a surface that will show an imprint, such as construction paper, or a sidewalk. You overpronate if the imprint shows a complete impression of your foot (as opposed to there being a space where your arch did not touch the ground).Overpronation


Non Surgical Treatment


Fortunately, there are simple things you can do to cure and correct your overpronation issues. Certain exercises help. Pull your toes back using a rolled up towel. Roll your feet over a golf or tennis ball for a minute. And do calf raises by standing up and lifting up on your toes. These all help reposition the foot and strengthen the muscles and tendons necessary for proper support. Beyond that, simple adjustments to footwear will help immensely.


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.
