Fig 2. Biceps brachii (BB) and first dorsal interosseous (FDI) response latencies for trials with startle signs (S+), and trials without startle signs (S-).

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.
