Orthotics are basically contoured wedges?
Orthotics act as shims or wedges that are applied between the ground and your feet. These wedges compensate for an angular deformity in your lower leg and ankle, present if not obvious in everyone. When orthotics are used during all weight bearing activity they basically bring the ground up to the foot, improve bio-mechanical function, and decreases clinical symptoms.
During activity this angular deformity is uncorrected, and your foot and leg must rotate inward to bring the bottom of the foot down to the ground, as you walk, run, and even stand.
When the wedge is in place, the foot does not need to collapse in order to come in contact with the ground. This collapsing motion of the foot is referred to as pronation. Because the leg is connected to the foot at the ankle, as the foot is supinated the leg is externally rotated.
When the wedges are in place, arch breakdown is limited and function during gait is changed.
The collapse of the foot (pronation) is the abnormal motion that occurs when we walk and stand that causes stress on all of the joints, tendons, and nerves that make up the foot. The internal rotation of the leg that is directly related to the collapse of the foot is the motion that places stress on the knee.
The amount of wedging in the orthotic design ultimately determines how much of the unwanted motion in the foot and leg is stopped. This is directly related to the stress on all of the anatomical structures, and the pain, symptoms, and deformity that result. Theta Orthotics provide more wedge, that will have more change on your gait, stop more pain, and restore more of your activity.
