Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | superficial blood perfusion | is measured by a speckle contrast imager (FLPI, Moor Instruments, England) | change from baseline, up to 10 minutes after the application | |
Primary | Warm Detection Threshold, and Heat Pain threshold | he tests for thermal sensation will all be performed using a PATHWAY ATS (Medoc Ltd, Israel) thermal sensory testing device | change from baseline, up to 10 minutes after the application | |
Primary | Cold Detection Threshold and Cold Pain threshold | the tests for thermal sensation will all be performed using a PATHWAY ATS (Medoc Ltd, Israel) thermal sensory testing device | change from baseline, up to 10 minutes after the application | |
Primary | Pain supra-threshold heat Stimuli | the tests for thermal sensation will all be performed using a PATHWAY ATS (Medoc Ltd, Israel) thermal sensory testing device | change from baseline, up to 10 minutes after the application | |
Primary | Alloknesis | s measured by using a mildy pruritic, non-painful von Frey filaments of a predetermined intensity (generally 5-30 milliNewton of force) | change from baseline, up to 10 minutes after the application | |
Primary | mechanical pain threshold and sensitivity | is performed using a pin-prick set (Aalborg University). The set consists of 8 needles each having a diameter of 0,6 mm and different force applications | change from baseline, up to 10 minutes after the application | |
Primary | itch rating | the subject will rate the itch for 10 minutes by using a visual analog scale (VAS) on a tablet. this scale goes from 0 to 100. 0 indicates "no itch" and 100 indicates "worst imaginable itch" | change from baseline, up to 10 minutes after the application | |
Secondary | pain rating | the subject will rate the pain for 10 minutes by using a visual analog scale (VAS) on a tablet. this scale goes from 0 to 100. 0 indicates "no pain" and 100 indicates "worst imaginable pain" | change from baseline, up to 10 minutes after the application |
