Figure Legend:
Flowchart of the algorithm used in this study for simulating the onset and progression of deep tissue injury. The algorithm incorporates finite element modeling as well as injury threshold and damage-stiffening law for muscle tissue obtained in previous experimental studies . IT, ischial tuberosity.
