    • Embodiment, tailoring, and trust are important for co-construction of meaning in physiotherapy after stroke: A qualitative study 

      Sivertsen, Marianne; De Jaegher, Hanne; Arntzen, Ellen Christin; Alstadhaug, Karl Bjørnar; Normann, Britt (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-20)
      Background and Purpose: Physiotherapy, with an emphasis on high intensity, individually tailored, and person‐centered treatment, is an effective route for recovery after a stroke. No single approach, however, has been deemed paramount, and there is limited knowledge about the patient experience of assessment, goal‐setting, and treatment in physiotherapy. In this study, we seek to report patient ...

    • Lack of association between cluster headache and PER3 clock gene polymorphism 

      Ofte, Hilde Karen; Tronvik, Erling Andreas; Alstadhaug, Karl Bjørnar (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-02-29)
      Background Cluster headache (CH) is regarded as a chronobiological disorder. The hypothalamic biological clock may thus be involved in the pathophysiology, but few studies have actually investigated this in CH patients. A variable number tandem repeat (VNTR) polymorphism of the PER3 clock gene has been associated to preferred daily rhythm (chronotype) in several studies. We aimed to study the ...

      Alstadhaug, Karl Bjørnar; Ofte, Hilde Karen; Kristoffersen, Espen Saxhaug (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-01)
      The concept that headache treatment per se may be the cause of chronification of headache is not new,3 but our understanding of this concept, and the terminology defining it, have changed throughout the years. The criteria for MOH are based on expert consensus rather than formal evidence. According to the current definition in the latest (2013) International Classification of Headache Disorders–3 ...

    • Transitorisk iskemisk attakk eller migreneaura? 

      Alstadhaug, Karl Bjørnar; Tronvik, Erling Andreas; Aamodt, Anne Hege (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-18)
      Migraine or migraine-like symptoms can contribute to a delayed stroke diagnosis. However, migraine with aura is a common stroke mimic and often the basis for acute thrombolytic therapy. It is probably also the reason why many patients are misdiagnosed with a transient ischemic attack. In this clinical review, we explain the factors that could differentiate a transient ischemic attack from a migraine ...
