Abstract

Background: Repetitive transcranial magnetic stimulation (rTMS) of the motor cortex modulates acute and chronic pain perception. The authors previously showed that rTMS over the primary motor cortex (M1) inhibited capsaicin-induced acute pain ascending through C-fibers. Objective: To investigate the effects of 1-Hz rTMS over Ml on acute experimentally induced pain mediated by AS-fibers (i.e., another type of acute pain). Methods: The authors examined whether rTMS over M1 affected laser evoked potentials (LEPs) in 13 normal subjects using thulium: yttrium-aluminum-garnet laser stimulation. Subjective pain-rating scores and LEPs obtained under three different conditions-rTMS, realistic sham stimulation, and a control condition with no stimulation-were compared. Results: The authors found that 1-Hz rTMS over Ml significantly aggravated the subjective pain and enhanced the N2-P2 amplitudes compared with the sham or control sessions. Because the pain-rating scores and the N2-P2 amplitudes correlated positively, the N2-P2 amplitudes in the present study can be regarded as the cortical correlate of subjective pain. Conclusions: Together with the authors' previous study on C-fiber pain, this facilitatory effect of repetitive transcranial magnetic stimulation on AS-fiber-mediated further strengthens the notion of a relationship between repetitive transcranial magnetic stimulation over Ml and pain perception.

<fC01 i1="01" l="ENG"><s0>Background: Repetitive transcranial magnetic stimulation (rTMS) of the motor cortex modulates acute and chronic pain perception. The authors previously showed that rTMS over the primary motor cortex (M1) inhibited capsaicin-induced acute pain ascending through C-fibers. Objective: To investigate the effects of 1-Hz rTMS over Ml on acute experimentally induced pain mediated by AS-fibers (i.e., another type of acute pain). Methods: The authors examined whether rTMS over M1 affected laser evoked potentials (LEPs) in 13 normal subjects using thulium: yttrium-aluminum-garnet laser stimulation. Subjective pain-rating scores and LEPs obtained under three different conditions-rTMS, realistic sham stimulation, and a control condition with no stimulation-were compared. Results: The authors found that 1-Hz rTMS over Ml significantly aggravated the subjective pain and enhanced the N2-P2 amplitudes compared with the sham or control sessions. Because the pain-rating scores and the N2-P2 amplitudes correlated positively, the N2-P2 amplitudes in the present study can be regarded as the cortical correlate of subjective pain. Conclusions: Together with the authors' previous study on C-fiber pain, this facilitatory effect of repetitive transcranial magnetic stimulation on AS-fiber-mediated further strengthens the notion of a relationship between repetitive transcranial magnetic stimulation over Ml and pain perception.</s0>
