Biceps brachii response amplitudes for trials with startle signs (S+), and trials without startle signs (S-) in FLEX and PINCH-FLEX tasks for the four analyzed stimulus intensities (multiples of sensory threshold, ST: 8×ST, 13×ST, 18×ST, 23×ST).

Abstract

<p>Bars correspond to mean (± SD) values for all subjects. Asterisks above the bars define the level of significance for group comparisons: * = <i>P</i> < 0.05, ** = <i>P</i> < 0.01, *** = <i>P</i> < 0.001.</p
