The analysis of the results of intellectual activity, as well as the main approaches to the manufacture and prevalence of the practical manufacture of splints and devices for the lower extremities using digital technologies is carried out.
46 organizations involved in the manufacture of lower limb orthoses using digital technology have been identified. The analysis of the results of intellectual activity for the period from 2005 to 2025 was carried out, 70 documents were identified for four search objects. The main trends in the development of digital orthosis technology have been identified: reducing manufacturing inaccuracies, reducing manufacturing time, automating manufacturing technology, and scaling technology.
