Development and testing of acoustically-matched hydrogel-based electrodes for simultaneous EMG-ultrasound detection

Surface Electromyograms (EMGs) provide a measure of muscle activity that has found application in the field of muscle fatigue, myoelectric control of prosthesis, movement analysis and others [1 –5]. Ultrasound imaging allows for the in-vivo assessment of muscle architecture, often considered in clinical applications and basic research [6–9]. By combining EMG and US imaging it would be possible to fully characterize the electromechanical properties of the muscle, from the neural excitat ion to the resulting muscle tissue displacement, and their possible adaptations with aging, rehabilitation, neurological disease, and injury.
