Conditioned pain modulation based on PCES and heat as test stimulus (TS).
| CPM Testing Paradigm Based on PCES | CPM Testing Paradigm Based on Heat Pain | |||
|---|---|---|---|---|
| Early CPM-Effect | Late CPM-Effect | Early CPM-Effect | Late CPM-Efect | |
| absolute number of responders (CPM-effect >0) | 27 | 22 | 25 | 23 |
| relative number [%] of responders | 96 | 79 | 89 | 82 |
| absolute magnitude of the CPM-effect | −16.0 ± 11.8 | −8.17 ± 9.99 | −13.5 ± 12.0 | −7.5 ± 8.4 |
| relative magnitude [%] of the CPM-effect | −22.7 ± 17.9 | −11.5 ± 14.3 | −29.2 ± 24.8 | −19.3 ± 23.4 |
CPM: conditioned pain modulation, PCES: painful cutaneous electrical stimulation; early CPM-effect: change of pain intensity during conditioning stimulus compared to baseline; late CPM-effect: change of pain intensity 5 min after application of the conditioning stimulus compared to baseline.
