This project includes data collected and simulated of healthy subjects performing two-handed lift.

We investigated the generalizability of a biomechanical simulation framework based on direct collocation to (1) variations in initial and final object positions and (2) variations in object mass. Motion capture and ground reaction force data were collected as each subject performed variations of two-handed lift. For each subject, mass and static motion capture trial data were used to scale a musculoskeletal model. Each scaled model was used in a direct collocation pipeline (leveraging OpenSim Moco) to predict joint coordinates and moments. We then compared these joint coordinates and moments against experimentally collected joint coordinates and moments to validate our direct collocation pipeline.
