OBJECTIVE Central fatigue is the inability of central commands to recruit maximum evocable muscle force during voluntary contraction. Here, we investigate how fatigue affects the inhibitory circuits of the motor cortex. METHODS MEPs, short interval intracortical inhibition (SICI) and intracortical facilitation (ICF) were evaluated using a paired pulse transcranial magnetic stimulation (TMS) paradigm before, during and after a series of 5 isometric contractions of the FDI muscle to 50% maximal… CONTINUE READING
