Over
Pronation (or Flat Feet)
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, possibly 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
additional stress to other parts of the foot. Therefore over-pronation can
often lead to a case of 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. People with
flat feet often 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 & 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.
Improper fitting footwear can lead to additional problems of the foot.
