Abstract

Laminate orthoses, preferably fiber-reinforced laminate orthoses, and preferably ankle-foot orthoses, are described. The shape, relative orientation, and positioning of layers comprising the orthoses may be configured and assembled in embodiments to manage the distribution of external static and dynamic loads through and within the orthosis. Peak stresses and strains developed in the orthosis from external static or dynamic loading may be managed such that they may be greater in certain areas and lesser in other areas. Layers of material comprising an orthosis may have unique and/or nonuniform shapes with cutouts, nonuniform or ply drop offs, and tapering. These irregular configurations may serve to focus, increase, decrease, or otherwise manage internal stresses developed from external static and dynamic loading at various target areas of an orthosis.
