Flat Foot
Flat Foot (Pes Planus)
Description
Pronation is the collapsing of the medial (inside) longitudinal arch and is a normal and necessary part of foot function that helps the foot absorb shock as it impacts the ground. Regardless of the height of one’s arches, everybody pronates to one degree or another. However, excessive amounts of pronation can in fact hinder shock absorption and result in harmful
stress being transferred to other parts of the foot, ankle, legs, knees, hips and even the back. This stress can result in injury to tissue and/or bone and can cause certain muscles to do more work than they can comfortably handle.
Symptoms
  • Because over-pronation can affect many areas of the lower body, not just the feet, the location of symptoms can vary widely.
  • Most common symptoms include pain in the heel, arch, ankle, Achilles tendon, lower leg, knee and hip.
Pedorthic Management
  • Custom orthotics or over-the-counter insoles to help control over-pronation and maintain proper alignment of the bones in the feet.
  • Supportive footwear that is torsionally stable (can’t be folded or twisted easily).
  • Over-pronators may require additional support in the form of a “stability shoe” that has a midsole that is firmer on the inside of the shoe to resist the foot’s tendency to roll inward.
Other Treatments
  • Physical therapy modalities include icing, taping, and massage, strengthening, stretching and other therapies targeting the affected area.
