Pain is a complex experience influenced by gender and genetics, and, by psychosocial and sensory experiences. Pain sensitivity is thus highly variable between individuals. In the present study we evaluate individuals´ pain perception in response to a number of different pain stimuli in 100 healthy volunteers (50 females and 50 males). The data will allow us to assess pain sensitivity, to predict pain responses and to investigate gender related differences in pain perception. A second aim is to evaluate the robustness of the different pain-tests since the tests are repeated with an interval of 2-4 weeks.
