The effects of different stimulation intensities on MEP amplitude and CSP duration at 10% EMG. (a) The MEP amplitude increased significantly as the stimulus intensity increased from 100% to 140% AMT. However, at stimulus intensities >140% AMT, no significant differences were observed in the MEP amplitudes. (b) CSP duration increased significantly as the stimulus intensity increased from 100% to 160% AMT. *1: 110% AMT > 100% AMT (p < 0.01). *2: 120% AMT > 100% AMT, 110% AMT (p < 0.01). *3: 130% AMT > 100% AMT, 110% AMT, 120% AMT (p < 0.01). *4: 130% AMT > 100% AMT, 110% AMT (p < 0.01). *5: 140% AMT > 100% AMT, 110% AMT, 120% AMT, 130% AMT (p < 0.01). *6: 150% AMT > 100% AMT, 110% AMT, 120% AMT, 130% AMT (p < 0.01). *7: 160% AMT > 100% AMT, 110% AMT, 120% AMT, 130% AMT (p < 0.01). *8: 160% AMT > 100% AMT, 110% AMT, 120% AMT, 130% AMT, 140% AMT, 150% AMT (p < 0.01).
