Does pain sensitivity change by migraine phase? A blinded longitudinal study
Hagen, Knut; Omland, Petter Moe; Stovner, Lars Jacob; Sand, Trond Halfdan; Uglem, Martin; Tronvik, Erling Andreas; Nilsen, Kristian Bernhard; Linde, Anders Mattias (Journal article; Peer reviewed, 2016)Objective: Studies suggest that pain thresholds may be altered before and during migraine headaches, but it is still debated if a central or peripheral dysfunction is responsible for the onset of pain in migraine. The ... -
Experimental pain and migraine: Investigating the effect of non-invasive cortical modulation of pain, and phasic alterations of pain in migraineurs
Uglem, Martin (Doctoral theses at NTNU;2018:130, Doctoral thesis, 2018)Background: Both clinical symptoms, imaging findings, and neurophysiological measures suggest varying cyclic alterations in CNS-function between, before, during and after the migraine headache. Altered pain perception ... -
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 ... -
Fluctuations of sensorimotor processing in migraine: A controlled longitudinal study of beta event related desynchronization
Mykland, Martin Syvertsen; Bjørk, Marte-Helene; Stjern, Marit; Omland, Petter Moe; Uglem, Martin; Sand, Trond (Journal article; Peer reviewed, 2019)Background The migraine brain seems to undergo cyclic fluctuations of sensory processing. For instance, during the preictal phase, migraineurs experience symptoms and signs of altered pain perception as well as other ... -
Habituation of laser-evoked potentials by migraine phase: a blinded longitudinal study.
Uglem, Martin; Omland, Petter Moe; Stjern, Marit; Gravdahl, Gøril Bruvik; Sand, Trond (Journal article; Peer reviewed, 2017)Background Migraineurs seem to have cyclic variations in cortical excitability in several neurophysiological modalities. Laser-evoked potentials (LEP) are of particular interest in migraine because LEP specifically targets ... -
Non-invasive cortical modulation of experimental pain in migraine
Uglem, Martin; Omland, Petter Moe; Engstrøm, Morten; Gravdahl, Gøril Bruvik; Linde, Mattias; Hagen, Knut; Sand, Trond (Journal article; Peer reviewed, 2016)Objective: To test the hypothesis that secondary somatosensory cortex (S2) is involved in the migraine pathogenesis, by exploring the effect of navigated repetitive transcranial magnetic stimulation (rTMS) to S2 on ... -
Obstructive sleep apnoea and headache: the HUNT3 polysomnography study
Filosa, James (Master thesis, 2021)Bakgrunn: Hovedformålet var å studere sammenhengen mellom obstruktiv søvnapné (OSA) og hodepine i populasjonsbasert utvalg. Studien hadde også som mål å studere sammenhengen mellom hodepine og komorbid insomni og OSA ... -
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 ... -
Visual evoked potentials in migraine: Is the "neurophysiological hallmark" concept still valid?
Hagen, Knut; Sand, Trond; Uglem, Martin; Tronvik, Erling Andreas; Linde, Mattias; Omland, Petter Moe (Journal article; Peer reviewed, 2016)Objective: Lack of habituation is considered a neurophysiological hallmark of migraine. However, the results of visual evoked potential (VEP) studies have been discrepant, possibly because of different stimulation parameters ... -
Visual Evoked Potentials in Migraineurs: Blinded Studieson Cortical Excitability and Habituation
Omland, Petter Moe (Doktoravhandlinger ved NTNU, 1503-8181; 2014:107, Doctoral thesis, 2014)Background The visual evoked potential (VEP) has been extensively studied in migraineurs. Several studies have shown that responses do not decline during continuous stimulation in migraineurs, as they do in headache-free ...
