Biceps brachii (BB) and first dorsal interosseous (FDI) response amplitudes for trials with startle signs (S+), and trials without startle signs (S-).

Abstract

<p>Dark square boxes represent the mean value corresponding to PINCH-FLEX task for both muscles. White square boxes represent the mean value corresponding to FLEX task for BB, and PINCH task for FDI. Data are mean (± SD) values for all subjects and intensities.</p
