Over-Pronation (Flat Feet)
Definition
Over-pronation, or flat feet, is a common
biomechanical problem that occurs in the walking process when a person's
arch collapses upon weight bearing. This motion can cause extreme stress
or inflammation on the plantar fascia, potentially causing severe
discomfort and leading to other foot problems.
Cause
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.
Treatment and Prevention
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. Improperly fitting footwear can lead to
additional foot problems.
If the problem persists, consult your foot doctor.
