When Biomechanics Meets Reality: The OpenSim Simulation Gap
In the realm of biomechanics, OpenSim stands as a cornerstone—a powerful, open-source simulation engine that enables researchers to model and analyze musculoskeletal dynamics. From studying gait patterns to designing prosthetics, OpenSim has been instrumental in advancing our understanding of human movement.
Yet, as with any model, there exists a gap between simulation and reality. Recent studies have highlighted discrepancies between OpenSim’s predictions and actual sensor data, raising questions about the fidelity of these simulations. This divergence, often referred to as the “sim-to-real gap,” underscores the challenges inherent in accurately modeling complex biological systems.
