Order of experimental trials during each testing session. All trials were conducted during each session.

Trial	Stimulus Induced Pain	Testing site	Parameters
1	Prolonged thermal stimulus at fixed pain intensity	Right thenar	Temperature adjusted to maintain a pain rating ~25% (eVAS)
2	Prolonged thermal stimulus at fixed temperature	Left thenar	Pain ratings to a 30 sec pulse at 47°C
