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.
In adults, the most common reason for the onset of Over-Pronation is a condition known as Post Tibial Tendonitis. This condition develops from repetitive stress on the main supporting tendon (Posterior Tibial Tendon) of the foot arch. As the body ages, ligaments and muscles can weaken. When this occurs the job of providing the majority of the support required by the foot arch is placed upon this tendon. Unfortunately, this tendon cannot bear the weight of this burden for too long. Eventually it fatigues under the added strain and in doing so the foot arch becomes progressively lower over a period of time.
People with overpronation may suffer from pain in the knees, hips, and low back. Overpronation itself does not necessarily cause any other symptoms but is a contributing factor of many foot conditions such as Plantar Facsiitis, Heel Spur Syndrome, Posterior Tibialis Tendon Rupture or Tendonitis, Hallux Valgus, Bunion Deformities, Metatarsalgia, Hallux Limitus or Hallux Rigidus, Hammer Toes, and Morton?s Neuroma.
Look at the wear on your shoes and especially running trainers; if you overpronate it's likely the inside of your shoe will be worn down (or seem crushed if they're soft shoes) from the extra strain.
Non Surgical Treatment
Studies have shown that the most effective way to dexrease a high Q angle and lower the biomechanical stresses on the knee joint is to prevent excessive pronation with custom-maflexible orthotics. One study found that using soft corrective orthotics was more effective in reduknee pain than a traditional exercise program. A more recent study showed that Q angle asymmetries, secondary to excessive pronation affecting knee alignment, can be effectivecontrolled or corrected utilizing custom-made, flexible orthotics. Another project involving meof a running club determined that 75% of those using orthotics eliminated or greatly reduced pain in the feet, ankles, shins, knees and hips
Many of the prevention methods for overpronation orthotics, for example, can be used interchangeably with treatment methods. If the overpronation is severe, you should seek medical attention from a podiatrist who can cast you for custom-made orthotics. Custom-made orthotics are more expensive, but they last longer and provide support, stability, and balance for the entire foot. You can also talk with a shoe specialist about running shoes that offer extra medial support and firm heel counters. Proper shoes can improve symptoms quickly and prevent them from recurring. Surgery can sometimes help cure and prevent this problem if you suffer from inherited or acquired pes planus deformity. Surgery typically involves stabilizing the bones to improve the foot?s support and function.
