Brief Summary:
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.
Detailed Description:
Carbon fiber custom dynamic orthoses (CDOs) have been used to improve function, reduce pain, and offload the foot and ankle for individuals with a number of conditions affecting the lower extremity.\[1-3\] CDOs consist of a proximal cuff that wraps around the leg just below the knee, a posterior carbon fiber strut that bends to store and return energy during mid to late stance, a semi-rigid carbon fiber footplate, and, in some cases, a foam heel wedge placed in the shoe. Studies have previously investigated the effects of design characteristics on gait biomechanics and foot loading, however, the effect of foot plate stiffness on resulting foot loading is unknown.
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. In this study, forces acting under the foot will be measured using wireless Loadsol insoles (Novel GMBH, St. Paul, MN) and limb mechanics will be measured using motion capture cameras and force plates as participants walk without an orthosis (NoCDO), with a CDO, and with a CDO plus added carbon fiber stiffening inserts (1/2) at a controlled walking speed. Participants will be provided a heel lift for the contralateral limb to prevent leg length discrepancies during walking if necessary. After walking in each condition, participants will complete questionnaires concerning pain and orthosis comfort.
