Trial characteristics_2
Developmental phase
Assessment
Primary outcomes
The evaluation of CPM effect before and after taking acetaminophen.
CPM effect is evaluated by pressure pain threshold (PPT) before and during conditioning stimulus.
Key secondary outcomes
the modulation of QST (the Thermal Pain Illusion(TPI), Temporal Summation(TS), Offset Analgesia(OA) etc) and the effect of background (for example, psychology test including SDS, STAI, PCS etc), and the stress evaluated by catecholamine concentrations in plasma, urine and sweat.

Other related information
Tonic conditioning stimulus (CS) is applied to the forearm by quantitative thermal stimulator device (QTSD) with a pain intensity of 70 on VAS (0-100) for about 5 minutes. For CPM evaluation, pressure pain threshold (PPT) is measured at contralateral forearm before, during, and after CS.
