Antagonist Muscle Prefatigue Increases the Intracortical Communication between Contralateral Motor Cortices during Elbow Extension Contraction

Figure 3

Sample entropy and fractal dimension of EEG in pre- and postfatigue elbow extension contractions. Sample entropy and fractal dimension of EEG at FC3, C3, FC4, and C4 were all found significantly increased in postfatigue contraction than in prefatigue contraction. Data are mean ± SE. Significant differences are indicated by asterisks ().
