Dynamic monitoring of forearm muscles using one-dimensional sonomyography system

Jing-Yi Guo, BSc, et al.

Figure. Placement of one-dimensional sonomyography (1-D SMG) transducer, surface electromyography (SEMG) electrodes, and electronic goniometer on forearm.

In this study, we used A-mode ultrasound signals to detect dynamic muscle thickness changes during the contraction of forearm muscles, a method known as sonomyography (SMG). SMG provides an alternative signal source for assessing muscle functions and prosthesis control based on dynamic architectural changes of muscles. We expect that SMG could be used together with electromyography and mechanomyography for a more comprehensive analysis of muscle function.
