Overpronation is a term used to describe excessive flattening of the plantar arch. Pronation is a normal part of our gait (the way we walk), and it comprises three movements: dorsiflexion, eversion, and abduction. Dorsiflexion is the upward movement of the foot, eversion describes the foot rolling in, and abduction is ?out toeing,? meaning your toes are moving away from the midline of your body. When these three motions are extreme or excessive, overpronation results. Overpronation is very common in people who have flexible flat feet. Flatfoot, or pes planus, is a condition that causes collapse of the arch during weight bearing. This flattening puts stress on the plantar fascia and the bones of the foot, resulting in pain and further breakdown.
Although there are many factors that can contribute to the development of these conditions, improper biomechanics of the body plays a large and detrimental role in the process. Of the many biomechanical elements involved, foot and ankle function perhaps contribute the most to these aches and pains.
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.
Duck stance: Stand with your heels together and feet turned out. Tighten the buttock muscles, slightly tilt your pelvis forwards and try to rotate your legs outwards. You should feel your arches rising while you do this exercise.
Calf stretch:Stand facing a wall and place hands on it for support. Lean forwards until stretch is felt in the calves. Hold for 30 seconds. Bend at knees and hold for a further 30 seconds. Repeat 5 times.
Golf ball:While drawing your toes upwards towards your shins, roll a golf ball under the foot between 30 and 60 seconds. If you find a painful point, keep rolling the ball on that spot for 10 seconds.
Big toe push: Stand with your ankles in a neutral position (without rolling the foot inwards). Push down with your big toe but do not let the ankle roll inwards or the arch collapse. Hold for 5 seconds. Repeat 10 times. Build up to longer times and fewer repetitions.
Ankle strengthener: Place a ball between your foot and a wall. Sitting down and keeping your toes pointed upwards, press the outside of the foot against the ball, as though pushing it into the wall. Hold for 5 seconds and repeat 10 times.
Arch strengthener: Stand on one foot on the floor. The movements needed to remain balanced will strengthen the arch. When you are able to balance for 30 seconds, start doing this exercise using a wobble board.
