Measurements of TMS parameters by observer 1. Sample size n = 18 for TT-TMS and n = 17 for cTMS. Each subject was examined eight times by each method. One subject (S4) was examined seven times with cTMS and eight times with TT-TMS. SICI was measured with the A-SICI and the T-SICI parallel protocol. Only values measured at ISIs 1 ms (SICI1ms), 2.5 ms (SICI2.5ms), 3 ms (SICI3ms), 1–3.5 ms (SICI1–3.5ms), and 1–7 ms (SICI1–7ms) are depicted. Each TMS parameter was measured twice in each session.
Point estimates for each subject were calculated as geometric means of their measurements. Data are displayed as medians with interquartile ranges [IQR] of subjects’ point estimates.
Normally distributed data for each subject was arithmetically averaged to calculate group mean (±SE) and SD.
