Ultrasound sensing-based intuitive proportional control: An evaluation study with upper-extremity amputees

Recent studies have shown that unintuitive control is a key factor leading to upper-extremity, myoelectric prostheses abandonment. We have developed a non-invasive modality to extract proportional control signals in the residuum using ultrasound imaging. In this study, we investigate the performance of this technology in upper-extremity amputees. We recruited 4 amputee subjects (Table 1) who currently use myoelectric prostheses. Subjects were...
