Pronation, in anatomical terms, means to rotate, and it applies to any rotational movement of a bone. Pronation in the feet involves an inward rolling of the foot throughout the gait which helps with the transfer of force. Normally the foot will move from the heel to the toes with only a small degree of pronation, with a slight inward roll from the outside of the heel to the inside of the foot which helps to support the body weight. Normal pronation involves the rolling of the foot to approximately 15 degrees. If you have normal foot arches, you are likely to be a neutral runner and will most likely pronate normally.
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.
You can test for pronation by looking at the leg and foot from the back. Normally you can see the Achilles Tendon run straight down the leg into the heel. If the foot is pronated, the tendon will run straight down the leg, but when it lies on the heel it will twist outward. This makes the inner ankle bone much more prominent than the outer ankle bone.
Non Surgical Treatment
When you see the doctor, he or she will likely perform a complete examination of your feet and watch you walk. The doctor will need to take x-rays to determine the cause of your flat feet. In some cases, further imaging may be needed, especially if your symptoms are severe and sudden in nature. Once you are properly diagnosed, your doctor will create an appropriate treatment plan. There are several options to correct overpronation, such as orthotics. In many cases, overpronation can be treated with non-surgical methods and over-the-counter orthotics. In severe cases, however, custom-made orthotics may work better. Orthotics provide arch support and therefore prevent collapse of the arch with weight bearing. They are made of materials such as spongy rubber or hard plastic. Your doctor will also want to examine your footwear to ensure they fit properly and offer enough medial support. Extra support and stability can be achieved with footwear that has a firm heel counter. If you are experiencing pain, you should be able to use over-the-counter pain medications such as ibuprofen to relieve symptoms.
Wearing the proper footwear plays a key role as a natural way to help pronation. Pronated feet need shoes that fit well, provide stability, contain supportive cushioning, are comfortable and allow enough room for your foot to move without causing pain or discomfort. Putting special inner heel wedges, known as orthotics, into your shoes can support a flatfoot while lowering risks of developing tendinitis, according to the American Academy of Orthopaedic Surgeons. More extensive cases may require specially fitted orthopaedic shoes that support the arches.
