Overview
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.
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
With over pronation, sufferers are most likely to experience pain through the arch of the foot. A lack of stability is also a common complaint. Over pronation also causes the foot to turn outward during movement at the ankle, causing sufferers to walk along the inner portion of the foot. This not only can deliver serious pain through the heel and ankle, but it can also be the cause of pain in the knees or lower back as well. This condition also causes the arch to sink which places stress on the bones, ligaments, and tendons throughout the foot. This may yield other common conditions of foot pain such as plantar fasciitis and heel spurs.
Diagnosis
Firstly, look at your feet in standing, have you got a clear arch on the inside of the foot? If there is not an arch and the innermost part of the sole touches the floor, then your feet are over-pronated. Secondly, look at your running shoes. If they are worn on the inside of the sole in particular, then pronation may be a problem for you. Thirdly, try the wet foot test. Wet your feet and walk along a section of paving and look at the footprints you leave. A normal foot will leave a print of the heel, connected to the forefoot by a strip approximately half the width of the foot on the outside of the sole. If you?re feet are pronated there may be little distinction between the rear and forefoot, shown opposite. The best way to determine if you over pronate is to visit a podiatrist or similar who can do a full gait analysis on a treadmill or using forceplates measuring exactly the forces and angles of the foot whilst running. It is not only the amount of over pronation which is important but the timing of it during the gait cycle as well that needs to be assessed.
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
Strengthen the glutes to slow down the force of the foot moving too far inward. Most individuals who over-pronate have weak glute muscles and strengthening this area is a must. A simple exercise to strengthen glutes is lateral tube walking across a field/court/room. Place a lateral stretch band around your ankles and move your leg sideways while keeping your feet forward.
