Table 1 Mean motor-evoked potential (MEP) amplitudes of the deltoid muscle (DM) of the affected and nonaffected sides of patients and the right and left sides in healthy controls during rest (Session 1) and low-level muscular activity of the DM in slight voluntary abduction of the shoulder against resistance (Session 2) after transcranial magnetic stimulation (TMS) at four different stimuli levels [resting motor threshold (RMT), RMT + increasing magnetic stimulus intensities given in percentage of stimulator output
