Design outcomes

Primary

Measure	Time frame
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).)	—
