PS6.1: Modeling Pressure Injury Conditions Caused by Toilet Seats

Using finite element computer simulations we have studied sitting on multiple toilet seats and have quantified resulting skin, fat and muscle tissue deformations. As expected, tissue deformations are greater on toilets relative to chairs. Moreover, the toilet-seat design, i.e. the support-surface widths and their inclinations strongly affect tissue loads. Computer modeling can effectively rate toilet seat designs by the potential tissue-injury risk, and regardless, toilet sitting time should be minimized for all at-risk populations.

Prof. Amit Gefen received the B.Sc. in Mechanical Engineering and M.Sc. and Ph.D. in Biomedical Engineering from Tel Aviv University in 1994, 1997, and 2001, respectively. During 2002-2003 he was a post-doctoral fellow at the University of Pennsylvania. He is currently a Full Professor at the Faculty of Engineering of Tel Aviv University. His research interests are in studying effects of biomechanical factors on cells, tissues and organs, with applications to chronic wounds.
