Abstract

Sonomyography (SMG), or ultrasound-based sensing of muscle deformation, is an emerging modality for upper limb prosthesis control with potential to significantly improve functionality. SMG enables spatiotemporal characterization of both superficial and deep muscle activity, making it possible to distinguish the independent contributions of individual muscles during functional movements. Early offline studies have shown that SMG is capable of accurately classifying motor intent among able-bodied individuals, but it has not yet been shown whether individuals with upper limb absence can successfully use this modality for prosthesis control. This paper describes our ongoing work towards implementing SMG control for individuals with upper limb absence in offline and real-time settings. We provide strong evidence supporting the feasibility of using SMG to control upper limb prostheses.
