As you walk, your weight shifts as your feet naturally move forward and up and down; just as naturally, they also slightly “flare out” or “pronate” just before the heel makes contact with the ground. Over pronation refers to an excessive amount of pronation, or pronation occurring at the wrong time in the gait cycle. This can cause the foot bones to shift position, which results in dysfunction of the bones and joints above the pronated foot. Over time, this dysfunction can cause stress or pain in the knees, hips, pelvis, low back, or neck. The foot itself may not hurt at all, even though it can be the principal cause of stress/pain elsewhere in the body.
When a foot and ankle pronates to a great degree, we call it over-pronation. Normally you can see the Achilles Tendon run straight down the leg into the heel. If the foot is over-pronated, the tendon will run straight down the leg, but when it lies on the heel it will twist outward. This makes the inner ankle bone much more prominent than the outer ankle bone.
An orthotic is a device inserted inside the shoe to assist in prevention and/or rehabilitation of injury. Orthotics support the arch, prevent or correct functional deformities, and improve biomechanics.
Prescription foot orthoses are foot orthoses which are fabricated utilizing a three-dimensional representation of the plantar foot and are specifically constructed for an individual using both weight-bearing and nonweightbearing measurement parameters and using the observation of the foot and lower extremity functioning during weight-bearing activities.
- Relief of pain
- The ability to return to previous levels of activity
- Reduction in the degree and duration of pronation
