Innovation

By applying complex network analysis to EMG recordings from muscles across the body, we provide a novel application of EMG with potential for translation to movement disorders. We use intermuscular coherence analysis to assess functional connectivity between muscles and map the muscle networks at different frequencies. We observe functional connectivity between muscles that are functional or anatomically related. The network structure is also dependent on the postural tasks that are performed. These muscle networks reflect common input from neural pathways that project to the spinal motor neurons. This novel approach allows to assess the neural circuitry involved in the coordination of muscles from non-invasive surface EMG recordings and has the potential for clinical application by identifying how coordination breaks down in movement disorders such as Parkinson's disease.

Full Proposal

"It’s a great honour to receive the 2018 Delsys Prize for promoting innovation in electromyography. The prize will help me to advance my research on muscle networks and investigate future clinical applications of this approach.”
