Developmental phase



Assessment

Primary outcomes

the relationship between the CPM effect and consumption amount and period using analgesic at before and after surgery
(CPM effect: Evaluation of CPM effect is assessed by Quantitative Sensory Testing (QST) such as Pressure Pain threshold measured by pressure algometer or threshold measured by von Frey filament as subjective evaluation and objective evaluation by Visual Analogue Scale (VAS) etc. The CPM effect is evaluated during and after conditioning stimulation. CPM effect is defined as ratio of pain threshold of TS during CS to pain threshold before application of CS (baseline).)

Key secondary outcomes

the relationship between the Thermal Pain Illusion(TPI), Temporal Summation(TS), Offset Analgesia(OA), background (for example, psychology test including SDS, STAI, PCS etc) and consumption amount and period etc using analgesic. The effect of stress on Catecholamine concentrations in plasma and 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.
