TMS stimulus–response curves
Muscle responses were obtained from the lightly contracted biceps brachii from 90% AMT to 190% AMT in 10% AMT increments in a semi-randomised protocol. Six stimulations were delivered for each of the 11 stimulator intensities, where a 20 s rest was provided between each stimulation. One participant did not reach 190% AMT as the intensity would have been higher than 100% MSO. MEP area was subsequently normalised to Mmax. The TMS intensity that produced the largest normalised MEP with the smallest stimulator output was chosen as the TMS intensity for the remainder of the testing session (54–84% MSO).
