An example of MMG-MEPs during FCR voluntary contraction with and without median nerve stimulation in a single subject.

<p>The MMG-MEPs responses from FCR muscle during FCR voluntary contraction without median nerve stimulation (A) and with median nerve stimulation (B). (C) and (D) show the MMG-MEPs from ECR muscles during FCR voluntary contraction without median nerve stimulation and with median nerve stimulation, respectively. Left: Wave forms of MMG-MEPs during 0% maximum FCR voluntary contraction (at rest). Middle: Wave forms of MMG-MEPs during 5% of the MVC. Right: Wave forms of MMG-MEPs during 20% of the MVC. Black vertical lines show the trigger of TMS.
