What this Trial Is About
Carbon fiber custom dynamic orthoses (CDOs) improve function, reduce pain, and offload the foot and ankle. CDOs include a proximal cuff that wraps around the leg just below the knee, a posterior carbon fiber strut that bends to store and return energy, and a semi-rigid carbon fiber footplate. The purpose of this study is to determine the effect of CDO use and CDO footplate stiffness on foot loading, limb mechanics, pain, and comfort.
