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 ... -
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 ... -
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 ... -
Pain sensitivity in young adults with juvenile idiopathic arthritis: a quantitative sensory testing study
Arnstad, Ellen Dalen; Iversen, Johanne Marie; Uglem, Martin; Glerup, Mia; Romundstad, Pål Richard; Sand, Trond; Rygg, Marite (Peer reviewed; Journal article, 2020)Background: To study for the first-time, pain perception, pain sensitivity, and self-reported pain in young adults with long disease duration of juvenile idiopathic arthritis (JIA) compared with controls. Methods: Children ... -
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 ...
