Overview
Over-pronation occurs when the foot collapses too far inward stressing the plantar fascia (the area underneath the arch of the foot.) Normally, one pronates every time he/she walks, but excessive pronation is called over-pronation. When this occurs it can cause pain in the feet, knees, hips, low back and even the shoulder.
Causes
Acquired "Flat Feet" this develops over a period of time rather than at birth (unlike Congenital "Flat Feet"). In children, many different factors may contribute to the development of this condition such as the type of shoes that a child wears, a child's sitting or sleeping positions or it may occur as some type of compensation for other abnormalities located further up the leg. Compensation may occur due to the rupture (tearing) of ligaments or tendons in the foot. One common reason for this condition is that the foot is compensating for a tight Achilles Tendon. If this tendon is tight it may cause the foot to point downward away from the body. This gives the body the perception that the affected leg is longer in length and the body attempts to compensate for the perceived additional length by flattening out the foot arch in an attempt to provide balance and stability.
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
Bunions, calluses and crooked toes may indicate alignment problems. So, it is important to ascertain the condition of a client's toes. Check the big toe to determine if the first joint of the toe is swollen, has a callus or bunion, and/or looks as though it abducts (i.e., hallux valgus) rather than pointing straight ahead. Also, look to see if the lesser toes seem to "curl up" (i.e., the person has hammer or claw toes). This may be indicative of damage to, or inflexibility of the plantar fascia caused by excessive flattening of the foot.
Non Surgical Treatment
Heel counters that make the heel of the shoe stronger to help resist/reduce excessive rearfoot motions. The heel counter is the hard piece in the back of the shoe that controls the foot?s motion from side-to-side. You can quickly test the effectiveness of a shoe?s heel counter by placing the shoe in the palm of your hand and putting your thumb in the mid-portion of the heel, trying to bend the back of the shoe. A heel counter that does not bend very much will provide superior motion control. Appropriate midsole density, the firmer the density, the more it will resist motion (important for a foot that overpronates or is pes planus), and the softer the density, the more it will shock absorb (important for a cavus foot with poor shock absorption) Wide base of support through the midfoot, to provide more support under a foot that is overpronated or the middle of the foot is collapsed inward.
Prevention
Firstly, a thorough and correct warm up will help to prepare the muscles and tendons for any activity or sport. Without a proper warm up the muscles and tendons around your feet, ankles and lower legs will be tight and stiff. There will be limited blood flow to the lower legs, which will result in a lack of oxygen and nutrients for those muscles. Click here for a detailed explanation of how, why and when to perform your warm up. Secondly, flexible muscles are extremely important in the prevention of most ankle and lower leg injuries. When muscles and tendons are flexible and supple, they are able to move and perform without being over stretched. If however, your muscles and tendons are tight and stiff, it is quite easy for those muscles and tendons to be pushed beyond their natural range of motion. To keep your muscles and tendons flexible and supple, it is important to undertake a structured stretching routine.
