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 ... -
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 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 ... -
Insufficient sleep may alter cortical excitability near the migraine attack: A blinded TMS crossover study
Mykland, Martin Syvertsen; Uglem, Martin; Stovner, Lars Jacob; Brenner, Eiliv; Snoen, Mari Storli; Gravdahl, Gøril Bruvik; Sand, Trond Halfdan; Omland, Petter Moe (Peer reviewed; Journal article, 2023)Background Migraine is a brain disorder with a multifaceted and unexplained association to sleep. Brain excitability likely changes periodically throughout the migraine cycle. In this study we examine the effect of ... -
Retinal structure and visual pathway function at school age in children born extremely preterm: a population-based study
Ingvaldsen, Sigrid Hegna; Moljord, Kyrre; Grøtting, Arnstein; Omland, Petter Moe; Dammann, Olaf; Austeng, Dordi Kristine; Morken, Tora Sund (Peer reviewed; Journal article, 2023)Background Children born extremely preterm (gestational age < 28 weeks) show reduced visual function even without any cerebral or ophthalmological neonatal diagnosis. In this study, we aimed to assess the retinal structure ... -
Sleep restriction alters cortical inhibition in migraine: A transcranial magnetic stimulation study
Mykland, Martin Syvertsen; Uglem, Martin; Neverdahl, Jan Petter; Øie, Lise Rystad; Meisingset, Tore Wergeland; Dodick, David W.; Tronvik, Erling Andreas; Engstrøm, Morten; Sand, Trond; Omland, Petter Moe (Peer reviewed; Journal article, 2022)Objective Migraine is a primary headache disorder with a well-known association with insufficient sleep. However, both the underlying pathophysiology of the disease and the relationship with sleep is still unexplained. In ... -
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 ...
