Foot type determines effect of orthotics on muscle activity
from Lower Extremity Review
Adding a lateral bar beneath foot orthoses does not significantly alter activity in the pronator muscles in people with high-arched feet, according to preliminary data from a poster entitled,
Effects of Two Types of Foot Orthoses on the Biomechanics of Participants with Cavus Feet During Walking.
During the course of the study, 15 participants with cavus feet walked quickly over a 5-meter walkway while wearing orthoses with no lateral bar, orthoses with a 1-centimeter wide lateral bar, and shoes only.
