• A tonic heat test stimulus yields a larger and more reliable conditioned pain modulation effect compared to a phasic heat test stimulus 

      Lie, Marie; Matre, Dagfinn; Hansson, Per; Stubhaug, Audun; Zwart, John-Anker; Nilsen, Kristian Bernhard (Journal article; Peer reviewed, 2017)
      Introduction: The interest in conditioned pain modulation (CPM) as a clinical tool for measuring endogenously induced analgesia is increasing. There is, however, large variation in the CPM methodology, hindering comparison ...
    • Comparing objective cognitive impairments in patients with peripheral neuropathic pain or fibromyalgia 

      Jacobsen, Henrik Børsting; Stiles, Tore C; Stubhaug, Audun; Landrø, Nils Inge; Hansson, Per (Peer reviewed; Journal article, 2021)
      Existing studies on cognitive impairments in chronic pain do not investigate peripheral neuropathic pain (PNP) or compare pain conditions in a satisfactory manner. Here we aimed to compare executive dysfunctions in PNP ...
    • 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 ...
    • Recommendations on practice of conditioned pain modulation (CPM) testing 

      Yarnitsky, D.; Bouhassira, D.; Drewes, A.M.; Filingim, R.B.; Granot, M.; Hansson, Per; Landau, R.; Marchand, S.; Matre, Dagfinn; Stubhaug, Audun; Nilsen, Kristian Bernhard; Treede, R.D.; Wilder-Smith, O.H.G. (Peer reviewed; Journal article, 2015)
      Protocols for testing conditioned pain modulation (CPM) vary betweendifferent labs/clinics. In order to promote research and clinical applicationof this tool, we summarize the recommendations of interested researchersconsensus ...
