Viste, Rannveig; Soosai, Joseph; Vikin, Truls; Thorsby, Per Medbøe; Nilsen, Kristian Bernhard; Knudsen, Stine (Journal article; Peer reviewed, 2017)We previously described the possible clinical effects of early monotherapeutic IV-immunomodulation (IVIg) treatment in sporadic1 but not in postH1N1 vaccination narcolepsy type 1 (NT1).2 We report here an early post-H1N1 ... -
Low Back Pain With Persistent Radiculopathy; the Clinical Role of Genetic Variants in the Genes SOX5, CCDC26/GSDMC and DCC
Lie, Marie; Pedersen, Linda Margareth; Heuch, Ingrid; Winsvold, Bendik K S; Gjerstad, Johannes; Hasvik, Eivind Olay; Nygaard, Øystein Petter; Grotle, Margreth; Matre, Dagfinn; Zwart, John Anker Henrik; Nilsen, Kristian Bernhard (Peer reviewed; Journal article, 2022)In a recently published genome-wide association study (GWAS) chronic back pain was associated with three loci; SOX5, CCDC26/GSDMC and DCC. This GWAS was based on a heterogeneous sample of back pain disorders, and it is ... -
Neurodegenerative interplay of cardiovascular autonomic dysregulation and the retina in early multiple sclerosis
Benavent, Sigrid Aune de Rodez; Nygaard, Gro Owren; Nilsen, Kristian Bernhard; Etholm, Lars; Sowa, Piotr; Gustavsen, Marte Wendel; Harbo, Hanne Flinstad; Drolsum, Liv; Laeng, Bruno; Kerty, Emilia; Celius, Elisabeth Gulowsen (Journal article; Peer reviewed, 2019)Introduction: Autonomic nervous system (ANS) symptoms are prevalent in multiple sclerosis (MS) as is neurodegeneration. Our aim was to explore the occurrence of ANS symptoms and retinal neurodegeneration in a newly diagnosed ... -
Pain sensitivity and thermal detection thresholds in young adults born preterm with very low birth weight or small for gestational age at term compared with controls
Iversen, Johanne Marie; Uglem, Martin; Indredavik, Marit Sæbø; Romundstad, Pål Richard; Nilsen, Kristian Bernhard; Sand, Trond; Rygg, Marite (Journal article; Peer reviewed, 2018)The objective of this prospective long-term follow-up study was to investigate whether somatosensory function is altered among young adults born preterm with very low birth weight (VLBW; ≤1,500 g) or small for gestational ... -

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 ... -
Sleep and pain: The effects of sleep restriction on pain and evoked potentials
Viken, Leif Andre (Master thesis, 2013)Objective: This study investigates the 1) effect of sleep restriction on a) neurophysiological and b) psychophysiological pain responses. We also investigated the 2) effect of sleep on habituation by introducing stimulus ... -
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) ... -
