Effects of Hand Vibration on Motor Output in Chronic Hemiparesis

Figure 3

Effect of vibration on the force development (). Mean (+SEM) values of before (C1), during (in each of the 3 vibration trials), 78 s after (C3), and 8–12 minutes after (C4) the 3 vibration trials in the control () and hemiparetic () groups. Asterisks show results of the Wilcoxon test comparing previbration values with the 3 vibration trials and the postvibration values. ; .
