OpenCap for measuring human movement with smartphones
OpenCap is an open-source cloud-based tool that enables users to perform 3D motion capture using two smartphones. Videos are processed automatically in the cloud to produce a scaled OpenSim musculoskeletal model and compute joint angles via inverse kinematics. Data can be downloaded for additional analysis or to generate muscle-driven simulations to study underlying loads, such as muscle forces and joint loading during motion. The paper was published in PLOS Computational Biology in October of 2023.
AddBiomechanics for computing inverse kinematics and dynamics automatically from motion capture files
AddBiomechanics is a freely available cloud service to process experimental motion capture data. Users import motion capture files, and the software then scales the body segments of a musculoskeletal model and computes kinematics and kinetics from the uploaded experimental data. The paper was published in PLOS One in November 2023.
OpenSim for musculoskeletal modeling and simulation
OpenSim is an open-source musculoskeletal simulation tool used by hundreds of research teams around the world to advance rehabilitation science. It provides musculoskeletal modeling and dynamic simulation capabilities to uncover the biomechanical causes of movement abnormalities and to design improved treatments.
