Diagnostic accuracy of the 5.07 monofilament test for diabetes polyneuropathy: influence of age, sex, neuropathic pain and neuropathy severity
Dunker, Øystein; Uglem, Martin; Kvaløy, Marie Bu; Løseth, Sissel; Hjelland, Ina Elen; Allen, Sara Maria; Vigeland, Maria Dehli; Kleggetveit, Inge Petter; Sand, Trond Halfdan; Nilsen, Kristian Bernhard (Peer reviewed; Journal article, 2023)Introduction There is a need for simple and cheap diagnostic tools for diabetic polyneuropathy (DPN). We aimed to assess the diagnostic accuracy of the 5.07/10 g monofilament test in patients referred to polyneuropathy ... -
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 ... -
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 ... -
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 ... -
Poorer sleep health is associated with altered brain activation during cognitive control processing in healthy adults
Smevik, Hanne; Habli, Sarah; Saksvik, Simen Berg; Kliem, Elisabeth; Evensmoen, Hallvard Røe; Conde, Virginia; Petroni, Agustin; Asarnow, Robert F.; Dennis, Emily L.; Eikenes, Live; Kallestad, Håvard; Sand, Trond Halfdan; Thompson, Paul M.; Saksvik-Lehouillier, Ingvild; Håberg, Asta; Olsen, Alexander (Peer reviewed; Journal article, 2023)This study investigated how proactive and reactive cognitive control processing in the brain was associated with habitual sleep health. BOLD fMRI data were acquired from 81 healthy adults with normal sleep (41 females, age ... -
