Phasic heat stimulation
C/s, pain
HEAT
Ten non-painful (− 1 °C below the pain threshold, right body side) and 10 painful (+ 3 °C above the pain threshold, right body side) heat stimuli (Medoc TSA-2001; Medoc Ltd, Ramat Yishai, Israel) were applied on the right lateral lower leg in a pseudo-randomized order. Each phasic heat stimulus (painful/non-painful) had the same characteristics (5 s (plateau); rate of change: 4 °C/s; baseline temperature: 38 °C; ISI of 15–20 s).
