Cooperation:

New Technologies – Research Centre (Department of Human Body Models), Ostbayerische Technische Hochschule Regensburg, Charles University (Faculty of Medicine in Pilsen).

Goals:

The main aim of the project was to create virtual models and their applications for the evaluation and optimization of the so-called manual perineal protection (MPP). This is a method of assisting the obstetrician during vaginal delivery, which can significantly reduce the risk of injury to the mother. The implementation of this method is highly dependent on its correctness and implementation. The use of sophisticated methods of computer modeling in the project made it possible for the first time to present an optimal description of manual assistance in childbirth. The results included the creation of a detailed musculoskeletal model of the hand and an optimized process of the MPP method. The results were presented through papers at international conferences, workshops and publications in scientific journals.
