Design outcomes

Primary

Measure	Time frame
the modulation of CPM in pain patient compared to the helthy volunteers (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. 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).)	—

Measure	Time frame
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), analgesics and the stress evaluated by Catecholamine concentrations in plasma, urine and sweat in pain patient compared to the healthy volunteers	—
