Design outcomes

Primary

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