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.
Over-pronation is very prominent in people who have flexible, flat feet. The framework of the foot begins to collapse, causing the foot to flatten and adding stress to other parts of the foot. As a
result, over-pronation, often leads to Plantar Fasciitis, Heel Spurs, Metatarsalgia, Post-tib Tendonitis and/or Bunions. There are many causes of flat feet. Obesity, pregnancy or repetitive pounding
on a hard surface can weaken the arch leading to over-pronation. Often people with flat feet do not experience discomfort immediately, and some never suffer from any discomfort at all. However, when
symptoms develop and become painful, walking becomes awkward and causes increased strain on the feet and calves.
Not all foot injuries affecting runners are necessarily down to a particular running gait; it is rarely that simple to diagnose how a foot problem developed . Simply being an overpronator does not
mean that a foot injury has been caused by the running gait and it could be due to a number of factors. However mild to severe overpronators tend to be at a higher risk of developing musculoskeletal
problems due to the increased stresses and strains which are placed on the body when the foot does not move in an optimum manner. The following injuries are frequently due to overpronation of the
feet. Tarsal tunnel syndrome. Shin splints. Anterior compartment syndrome. Plantar fasciitis. Achilles tendonitis. Bunions. Sesamoiditis. Stress fractures. Back and hip pain. Ankle pain.
Your healthcare provider will ask about your symptoms, medical history, and activities and examine your feet. Your provider may watch you walk or run. Check the motion of your feet when they strike
the ground. Look at your athletic shoes to see if they show an abnormal pattern of wear.
Non Surgical Treatment
Over-Pronation can be treated conservatively (non-surgical treatments) with over-the-counter orthotics. These orthotics should be designed with appropriate arch support and medial rearfoot posting to
prevent the over-pronation. Footwear should also be examined to ensure there is a proper fit. Footwear with a firm heel counter is often recommended for extra support and stability. Improper fitting
footwear can lead to additional problems of the foot. If the problem persists, call your doctor to schedule an appointment.
With every step we take, we place at least half of our body weight on each foot (as we walk faster, or run, we can exert more than twice our body weight on each foot). As this amount of weight is
applied to each foot there is a significant shock passed on to our body. Custom-made orthotics will absorb some of this shock, helping to protect our feet, ankles, knees, hips, and lower back.
