Simulation Software Recreates Complex Movements For Medical, Rehabilitation, and Basic Science (image) PLOS Share Print E-Mail Caption Movement is fundamental to human and animal life, emerging through interaction of complex neural, muscular, and skeletal systems. OpenSim is open-source software that unites state-of-the-art models and methods from biology, neuroscience, mechanics, robotics, and computer science to create fast and accurate physics-based simulations of movement. OpenSim complements experiments by computing muscle forces and other quantities that are difficult to measure, and enables prediction of movements such as bipedal locomotion in human ancestors and neuromuscular adaptations to exoskeletons or orthopaedic surgeries.
