• Development and course of chronic pain over 4 years in the general population: The HUNT pain study 

      Landmark, Tormod; Dale, Ola; Romundstad, Pål Richard; Woodhouse, Astrid; Kaasa, Stein; Borchgrevink, Petter Chr. (Journal article; Peer reviewed, 2018)
      Background Epidemiological studies of chronic pain frequently report high prevalence estimates. However, there is little information about the development and natural course of chronic pain. Methods We followed a ...
    • Psychophysical or spinal reflex measures when assessing conditioned pain modulation? 

      Lie, Marie; Petriu, Elena; Matre, Dagfinn; Hansson, Per; Andersen, Ole Kæseler; Zwart, John-Anker; Nilsen, Kristian Bernhard (Journal article; Peer reviewed, 2019)
      Background Assessing conditioning pain modulation (CPM) with spinal reflex measures may produce more objective and stable CPM effects than using psychophysical measures. The aim of the study was to compare the CPM effect ...
    • Reward responsiveness in patients with chronic pain 

      Elvemo, Nicolas-Andreas L.; Landrø, Nils Inge; Borchgrevink, Petter Chr.; Håberg, Asta (Journal article; Peer reviewed, 2015)
      Background: It is proposed that changes in reward processing in the brain are involved in the pathophysiology of pain based on experimental studies. The first aim of the present study was to investigate if reward drive ...
    • Sleep restriction does not potentiate nocebo‐induced changes in pain and cortical potentials 

      Ree, Anbjørn; Nilsen, Kristian Bernhard; Knardahl, Stein; Sand, Trond; Matre, Dagfinn (Peer reviewed; Journal article, 2019)
      Background: The increased pain sensitivity following reduced sleep may be related to changes in cortical processing of nociceptive stimuli. Expectations shape pain perception and can inhibit (placebo) or enhance (nocebo) ...
