The effect of sleep restriction on laser evoked potentials, thermal sensory and pain thresholds and suprathreshold pain in healthy subjects
Ødegård, Siv Steinsmo; Omland, Petter Moe; Nilsen, Kristian Bernhard; Stjern, Marit; Gravdahl, Gøril Bruvik; Sand, Trond (Peer reviewed; Journal article, 2015)Objective: Sleep restriction seems to change our experience of pain and reduce laser evoked potential (LEP) amplitudes. However, although LEP-habituation abnormalities have been described in painful conditions with comorbid ... -
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 ... -
Impaired awareness of hypoglycemia in adults with type 1 diabetes is not associated with autonomic dysfunction or peripheral neuropathy
Olsen, Sandra Elise; Bjørgaas, Marit Ragnhild Rokne; Åsvold, Bjørn Olav; Sand, Trond; Stjern, Marit; Frier, Brian; Nilsen, Kristian Bernhard (Peer reviewed; Journal article, 2015)OBJECTIVE: Impaired awareness of hypoglycemia (IAH) is a risk factor for severe hypoglycemia in people with insulin-treated diabetes; autonomic neuropathy has been suggested to underlie its development. The aim was to ... -
Sleep quality, arousal and pain thresholds in migraineurs: a blinded controlled polysomnographic study
Engstrøm, Morten; Hagen, Knut; Bjørk, Marte Helene; Stovner, Lars Jacob; Gravdahl, Gøril Bruvik; Stjern, Marit; Sand, Trond (Journal article; Peer reviewed, 2013)Background Our aim was to compare subjective and objective sleep quality and arousal in migraine and to evaluate the relationship between sleep quality and pain thresholds (PT) in controls, interictal, preictal and postictal ... -
The epidemiology of headache disorders: a face-to-face interview of participants in HUNT4
Hagen, Knut; Åsberg, Anders Nikolai; Uhlig, Benjamin Langsæter; Tronvik, Erling Andreas; Brenner, Eiliv; Stjern, Marit; Helde, Grethe; Gravdahl, Gøril Bruvik; Sand, Trond (Journal article; Peer reviewed, 2018)Background The primary aim of this cross-sectional population-based study was to evaluate the 1-year prevalence of common headache disorders by a face-to-face interview. Methods The fourth wave of Nord-Trøndelag ... -
The relationship between obstructive sleep apnea and insomnia: a population-based cross-sectional polysomnographic study.
Uhlig, Benjamin Langsæter; Hagen, Knut; Engstrøm, Morten; Stjern, Marit; Gravdahl, Gøril Bruvik; Sand, Trond (Journal article; Peer reviewed, 2018)Background The relationship between insomnia and objectively measured obstructive sleep apnea (OSA) severity has not previously been investigated in both genders in the general population. The main aim of this population-based ... -
Validation of questionnaires for restless legs syndrome in the general population: the Trøndelag Health Study (HUNT)
Filosa, James; Omland, Petter Moe; Hagen, Knut; Langsrud, Knut; Brenner, Eiliv; Knutsen, Andreas; Drange, Ole Kristian; Gravdahl, Gøril Bruvik; Stjern, Marit; Engstrøm, Morten; Sand, Trond (Peer reviewed; Journal article, 2022)Questionnaires for restless legs syndrome have rarely been validated against face-to-face interviews in the general population. We aimed to validate the modified Norwegian, seven-item Cambridge-Hopkins restless legs syndrome ...
