With increasing age, the probability of neurological diseases such as strokes, cancers, meningitis and Parkinson’s also increase. A stroke, for instance, often leads to damage to the central nervous system and therefore subsequent problems within the musculoskeletal system occur. Such movement restrictions are currently treated with the help of orthoses. However, commercial passive orthoses have the disadvantage that not all functions are covered, e. g. supporting all phases of the gait cycle. Full functionality can only be ensured with heavier active orthoses. The aim of this contribution is to develop a new hybrid user-centered/lightweight-design approach with which fully functional, passive lightweight orthoses can be designed and developed effectively in the future. Therefore, the methodology according to PAHL/BEITZ is expanded by including user-specific functions and attributes. The developed approach is applied on an ankle-foot-orthosis.
