Name Time Method <p>Laser evoked potential: Amplitude of N2 and P2 peaks of laser evoked potential<br /><br>(LEP), AUC (area under curve) of LEP between 175 - 500 ms after stimulus,<br /><br>latencies of N2 and P2 peaks of LEP during HF, LF stimulation and without<br /><br>stimulation.<br /><br>VAS: After each series of randomly applied stimuli, the participant is asked to<br /><br>estimate their subjective measurement of pain intensity on a Visual Analog<br /><br>Scale (VAS), these scores are compared to the VAS scores as noted in a pain<br /><br>diary a week before these tests.</p><br>
