 3D printing of hand-ought hoses may improve performance of activities of daily life in chronic hand conditions, but more research is needed to assess effectiveness, costs, and production time compared to conventionally custom-fabricated-ought hoses. This study aims to evaluate the preliminary effectiveness of 3D, printed-ought hoses, production time and costs, and experiences of participants and orthotists with the manufacturing process. This article was authored by Franz Nollett, Merrill and Brehm, Tonya Ud, and others.
