Effects of Hand Vibration on Motor Output in Chronic Hemiparesis

Figure 2

Effects of vibration on MEPs amplitude of the FDI. (a) An example of MEPs recording before (C1), during (C2), 1-minute after (C3), 1.5–2.5 minutes after (C4), and 8-9 minutes after (C5) vibration in a control subject (upper trace) and a mild (middle trace) and severe (lower trace) hemiparetic patient. (b) Mean (+SEM) of MEP amplitudes showing the effect of vibration in control () and hemiparetic () subjects in the 5 time periods..
