The project has the following overall objectives to identify MMH tasks in the Danish supermarket sector with a relatively high physical load using 3D inertial motion capture and electromyography (EMG) in the field. The kinematic data will subsequently be used as input to musculoskeletal models, which, combined with ground reaction force prediction, can estimate the forces in the knee, lumbar spine and shoulders. These data will provide immediate feedback to the industry about potentially hazardous work tasks and help identify ways to reduce the physical loads on the workers through ergonomic initiatives.
