Mean short interval intracortical inhibition (SICI), over interstimulus intervals 1–7 ms, was significantly reduced when recording over the (A) abductor pollicis brevis (APB), (B) first dorsal interosseous (FDI), and (C) abductor digit minimi (ADM) muscles. (D) The reduction in mean SICI was most prominent when recording over the APB muscle. ***P<0.001; ****P<0.0001.
