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 ... -
Cardiovascular Health Effects of Shift Work with Long Working Hours and Night Shifts: Study Protocol for a Three-Year Prospective Follow-Up Study on Industrial Workers
Lunde, Lars-Kristian; Skare, Øivind; Mamen, Asgeir; Sirnes, Per Anton; Aass, Hans Christian Dalsbotten; Øvstebø, Reidun; Goffeng, Elisabeth Martinsen; Matre, Dagfinn; Nielsen, Pia; Heglum, Hanne Siri Amdahl; Hammer, Stine Eriksen; Skogstad, Marit (Journal article; Peer reviewed, 2020)There is a plausible association between shift work and cardiovascular disease (CVD), which may be due to disruption of the circadian rhythm causing hormonal changes and metabolic disturbances, resulting in high blood ... -
Effects of insufficient sleep on sensorimotor processing in migraine. A randomised, blinded crossover study of event related beta oscillations
Mykland, Martin Syvertsen; Uglem, Martin; Bjørk, Marte-Helene; Matre, Dagfinn; Sand, Trond Halfdan; Omland, Petter Moe (Peer reviewed; Journal article, 2023)Background Migraine has a largely unexplained connection with sleep and is possibly related to a dysfunction of thalamocortical systems and cortical inhibition. In this study we investigate the effect of insufficient sleep ... -
Experimental pain after sleep restriction and cortical excitability in migraine patients: From cross-sectional studies in the interictal phase to crossover studies on the effect of sleep restriction
Neverdahl, Jan Petter (Doctoral theses at NTNU;2024:10, Doctoral thesis, 2024)Migraine is a common and debilitating primary headache disorder. Despite having pronounced personal, societal, and economical costs, the pathophysiology of migraine is not fully elucidated. Migraine patients experience ... -
Experimental sleep restriction increases latency jitter in pain elicited cortical responses
Hansen, Johannes Orvin; Omland, Petter Moe; Nilsen, Kristian Bernhard; Sand, Trond; Matre, Dagfinn (Peer reviewed; Journal article, 2021)Objective Previous studies have shown increased pain scores to painful stimulation after experimental sleep restriction, but reduced or unchanged magnitude of the event related potentials (ERPs) when averaged in the ... -
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 ... -
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 ... -
Shift work and pain : a quantitative EEG investigation into the effects of shift work and nocebo on pain perception
Ree, Anbjørn (Master thesis, 2016)Introduction: Shift work is associated with increased prevalence of pain and shift workers commonly report reduced sleep, which is related to increased pain sensitivity. Thus, night shift work (NSW) may potentially lead ... -
Sleep and Pain: An EEG study of how sleep affects pain perception
Rødsjø, Eline (Master thesis, 2020)Bakgrunn: Eksperimentelle studier har vist at søvnmangel er assosiert med endringer i smertepersepsjon. Flere hjerneavbildningsstudier trengs for å utvikle objektive nevrofysiologiske korrelater til smerte. Hensikt: Denne ... -
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) ...
