Study design. Each subject was examined on four sessions on two separate days, 5–7 d apart: two sessions in the mornings and two sessions in the afternoons. A-SICI and T-SICI protocols were repeated twice in each session. These examinations were performed by the same observer (observer 1). Two TMS examinations (one A-SICI examination and one T-SICI examination) were additionally performed by a second observer (observer 2) on each subject. The examinations were done in continuation of one of the sessions. In total, nine A-SICI and nine T-SICI examinations were performed on each subject.
