Abstract. During the period of rehabilitation after leg injuries, a person, along with limited mobility, experiences difficulties in the selection of wardrobe items. Rehabilitation programs recommend wearing external fixators positioning the parts of the musculoskeletal system in
the desired configuration. External anchors are a variety of designs that include stiffeners made of metal or composite materials. The spatial configuration of the fixation devices and the duration of their operation depend on the severity of the disease. External fixators
change the dimensions of the legs; therefore, many patients for the period of treatment update their wardrobe of waist clothes and shoes for large-sized items. In addition, the operation of devices such as the Ilizarov apparatus is accompanied by the wearing of special garments
– foot covers that protect the damaged leg area from environmental influences. The compositional and constructive solution of typical models of foot covers is very simple. The study found that in society there is a large group of consumers who prefer the individuality of
the image during the period of rehabilitation treatment. The high degree of demand for personalized models of garments of the rehabilitation assortment determined the studies presented in the article. The authors have developed and tested a methodology for designing
the spatial shape of sewing foot covers in parametric graphic CAD. Input parameters for three-dimensional design of products are 3D scan images of digital leg models and features of the spatial configuration of external fixators. The article presents the general provisions of the
research topic under study on the example of designing rehabilitation covers for the Ilizarov apparatus.
Keywords: digital twins of figures, assessment of appearance, rehabilitation products, 3D parametric design.
