MIG group: subjects with episodic migraine (n = 24); HC group: healthy controls (n = 19). RTh: single stimulus reflex threshold of the nociceptive withdrawal reflex (NWR); Area: area under the curve (mV*ms) of the NWR at RTh; VAS-RTh: pain perception as rated on a 0- to 10-point visual analogue scale at RTh; TST: temporal summation threshold of the NWR; VAS-TST-1 and VAS-TST-5: subjective pain perception of the first and fifth stimulus of the TST according to a 0- to 10-point visual analogue scale. In bold: statistically significant comparisons.
HC, healthy controls; MIG, migraine; RTh, reflex threshold; TST, temporal summation threshold; VAS, visual analogue scale.
