Figure 5 Motor-evoked potentials (MEPs) amplitude in experiment 2MEPs amplitude recorded at baseline (T0), immediately after the former intervention (T1), and the latter intervention (T2), 30 min (T3) after the latter intervention in the electroacupuncture (EA)-priming group (red circles) and motor training (MT)-priming group (black squares). Note that in the EA-priming group, the MEPs amplitude increased significantly when the EA was intervened alone (T1 compared with T0); whereas, when the MT followed, the MEPs amplitude remained unchanged (T2 and T3 compared with T0). In the MT-priming group, the MEPs amplitude increased significantly when the MT was intervened alone (T1 compared with T0); whereas, when the EA followed, the MEPs amplitude remained unchanged (T2 and T3 compared with T0). Values are mean±SD. * Indicates significant differences (P<0.05) compared with baseline (T0). This figure was produced using GraphPad Prism 10 by GraphPad Software.
