Fig. 2.

Repeatability of LICI at subject and ISI level. The intraclass correlation coefficient (ICC) showing the repeatability of inhibition ratios between the first and second session for A. each interstimulus interval (ISI) and B. each subject. Repeatability of the manual group is shown in red dots and of the robot group in red triangles; inhibition ratios of both hemispheres pooled. The horizontal black lines, at ICC = 0.6 and 0.8, represent thresholds for moderate and good repeatability. Overall, a large variation in repeatability is seen for ISIs (2A) and subjects (2B), ranging from poor to good levels of agreement.
