The proposed study is designed to evaluate how foot loading changes during initial accommodation to a carbon fiber custom dynamic orthosis (CDO), after targeted training with or without visual feedback of foot loading, and after take-home use of the CDO. This study will quantify initial offloading associated with CDO use and determine if visual feedback of foot loading and additional take-home use of the CDO can further reduce forces, as orthotists work to provide CDOs to patients.
This study is designed to evaluate the effects of initial accommodation, CDO related training, and take-home use on foot loading during gait. In this study, adult participants who experienced an injury below the knee and require a CDO will walk without the CDO, then with the CDO following initial prescription, after training with or without visual force feedback, and after additional take-home use of the CDO. Participants will be randomized to to training with or without visual feedback of foot loading forces. Wireless force measuring sensors will be used to measure forces under the foot with…
