Name Time Method the relationship between Conditioned Pain Modulation (CPM), Thermal Pain Illusion (TPI), Temporal Summation (TS), Offset Analgesia (OA) and analgesic consumption, postoperative pain, and patient background (for example, psychology test including SDS, STAI, PCS etc.) (CPM effect: 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). TPI: paradoxical sensation caused by cold heat pulse stimulation TS: triggered by repeated thermal stimulation and assessed by VAS. OA: triggered by thermal stimulation and assessed by VAS.)
- Secondary Outcome Measures
Name Time Method The effect of stress on Catecholamine concentrations in plasma and urine and sweat.
