Foot Pain

I think we all agree that any dysfunction of the foot and ankle complex can cause problems into the knees, lumbo-pelvic-hip complex, spine and upper extremities. Because of this, people must wear proper footwear to protect the foot and prevent injuries…to read more


Flat feet (Pronation) & Orthotics

A common foot dysfunction, such as overpronation or flat feet, can actually lead to dysfunctions in many other parts of the body. This is because the body is an interconnected Kinetic Chain in which the feet, knees, low back, shoulder, and upper extremity regions communicate and sometimes transfer dysfunction.

Dr. Tucker checks the feet for flat feet, overpronation and high arches. Dysfunction in the feet can lead to joint and muscle dysfunction in the knee which in turn leads to abnormal tension in the hips and low back which directly affects the shoulder region which causes shoulder, neck, and upper extremity injuries.

Dr. Tucker uses a laser guided sytem to identify the need for orthotics and has the ability to see if the orthotics you are using are the correct ones. Your current orthotics could be worn out and causing dysfunction without you even knowing. Dr. Tucker’s system to evaluate orthotics is part of his integrative assessment, which consists of:

  1. Movement assessment
  2. Range of motion measurement
  3. Soft tissue, muscle & fascia testing

This laser exam process allows for you and Dr. Tucker to correctly diagnose the need for proper orthotics for dysfunction in the feet.


Navicular Drop Test

Use this test to help you determine if you need orthotics.

All you need are a marking pen and a piece of 3″x5″ card stock. With the patient sitting comfortably (feet on the floor, but non?weightbearing), palpate the medial aspect of each foot and find the navicular prominence (the most prominent bony landmark found inferior and somewhat anterior to the medial malleolus). Using the pen, make a mark on the patient’s skin at the point of the navicular prominence. Stand the card on the floor next to the medial arch of the foot and mark the card at the level of the navicular prominence.

Next, ask the patient to stand, in a relaxed position. Once the arch is weightbearing, the navicular prominence will be somewhat lower. Make a second mark on the same side of the card at the new level of the navicular prominence. Repeat this procedure with the other foot.

Now measure the difference between the two marks for each foot.

If there is a drop of 4 mm. or more in the arch between sitting and standing, or if there is an obvious asymmetry from left to right, this is objective evidence of a functional foot problem ?? hyperpronation/collapse of the medial arch. This condition is best treated with flexible orthotics designed to be worn during all weightbearing activities.
