The long-term goal of our work is to restore functional arm movements in people with spinal cord injury or other neuromuscular problems. One approach is to use coordinated, electrical stimulation of muscles, which requires advanced command and control algorithms to provide natural control of movement. To facilitate development of such systems, where the user is an integral part of the control loop, we are developing tools for fast simulation of the musculoskeletal system to allow user-in-the-loop testing of potential solutions.

The aim of this work was therefore to create a 3D musculoskeletal model capturing the dynamics of the human arm and shoulder girdle that runs faster than real time. This allows the model to be used in a simulation environment under the control of a potential prosthesis user to test novel control algorithms, command sources and user learning. In this webinar I will describe the methods used to create the model and perform simulations in real-time, including how we integrate OpenSim into our workflow. I will also discuss some of the limitations of the current model, and outline some of the potential applications, including control of a virtual arm using a brain-computer interface.
