Deep muscle activity exposed via M-mode ultrasounds

M-Mode ultrasound is being tested in a variety of studies as a non-invasive, clinical tool to assess deep muscle activity, as opposed to electromyography which is widely considered to be highly invasive and painful.

Electromyography (EMG) is a technique for evaluating and recording the electrical activity produced by skeletal muscles. EMG is performed using an instrument called an electromyograph, to produce a record called an electromyogram. An electromyograph detects the electrical potential generated by muscle cells when these cells are electrically or neurologically activated. The signals can be analyzed to detect medical abnormalities, activation level, recruitment order or to analyze the biomechanics of human or animal movement.
