  Purpose
Conditioned pain modulation is the ability of the spine to describe changes in pain perception, if two different painful stimulations take place. The reliability of the conditioned pain modulation has not been studied, the instruments used to measure the conditioned pain modulation are sparse and have proven difficult to use in a well reproductible way. This study is using an existing pain test, relying on the reflex in a muscle after a painful electrical stimulation. We will test 34 healthy volunteers in order to test the reliability of the conditioned pain modulation with the nociceptive withdrawal reflex combined to a ice water test.
