Sonomyography (SMG) or ultrasound-based sensing of muscle deformation is an emerging modality for enhancing upper limb prosthesis control, offering the ability to spatially resolve muscle activity in both superficial and deep layers. Prior studies from our group as well as other groups have demonstrated the feasibility of SMG for prosthetic control using clinical ultrasound imaging systems and as well as miniaturized wearable ultrasound systems with several single-element ultrasound transducers for tracking muscle interfaces. However, the performance of SMG using miniaturized ultrasound sensors incorporated into a prosthetic socket has not been evaluated thus far. In this study, we incorporated single element ultrasound sensors into custom designed prosthetic sockets for two individuals with congenital transradial limb difference and evaluated the performance of classification and proportional control. Our work demonstrates the potential for SMG as well as highlights some challenges that need to be overcome.
