Carbon fiber custom dynamic orthoses (CDOs) include a full-length footplate, a stiff posterior spring, and a cuff that wraps around the leg below the knee. CDOs restore function after limb trauma, decrease forefoot loading, and reduce pain. However, initial introduction to a CDO is not consistent, so this study is being conducted to determine if different methods of training alter forefoot loading during gait. Unimpaired adult participants will be randomized to one of three groups: 1) no feedback, 2) visual feedback of forefoot force, and 3) visual feedback of cuff forces. All participants will walk at a controlled speed on a treadmill without the CDO, after initial introduction to the CDO, and after completing two rounds of training in the CDO.
Carbon fiber custom dynamic orthoses (CDOs) restore function for individuals with limb trauma. CDOs include a full-length footplate, a stiff posterior spring, and a proximal cuff that wraps around the leg below the knee. A key benefit of CDOs is the ability to decrease forefoot loading, which may reduce pain during walking. However, initial introduction to a CDO is not consistent and some individuals struggle to relax their lower leg muscles and rely on the CDO for support, reducing the potential offloading benefits of the CDO and increasing the risk of abandoning the CDO. In this study we wi…
Inclusion Criteria: 1. Ages 18-65. 2. Without current complaint of lower extremity pain, spine pain, open wounds or active infection. 3. Ability to hop without pain. 4.

The carbon fiber custom dynamic orthosis (CDO) used in this study will consist of a semi-rigid carbon fiber footplate, a carbon fiber posterior strut, and a proximal cuff that wraps around the leg below the knee.
