      Objectives: To study the development of dizziness, caloric function, and postural sway during long-term observation of untreated vestibular schwannoma patients. Study Design: Retrospective review of a prospectively maintained ...
    • Long-Term Survival in 1,931 Patients With Dizziness: Disease- and Symptom-Specific Mortality 

      Berge, Jan Erik; Nordahl, Stein Helge Glad; Aarstad, Hans Jørgen; Goplen, Frederik Kragerud (Journal article; Peer reviewed, 2021)
      Objective: To evaluate mortality among patients referred for suspected vestibular disorder and to examine whether specific symptoms or disorders predict long-term survival among patients with dizziness or vertigo. Study ...
    • Long-term symptoms in dizzy patients examined in a university clinic 

      Wilhelmsen, Kjersti Thulin; Ljunggren, Anne Elisabeth; Goplen, Frederik Kragerud; Eide, Geir Egil; Nordahl, Stein Helge G. (Peer reviewed; Journal article, 2009-05-16)
      Background: The long-term course of dizziness was investigated combining medical chart and survey data. The survey was undertaken median (interquartile range (IQR)) 4.6 (4.3) years after the initial medical examination. ...
    • Measuring pressure pain threshold in the cervical region of dizzy patients-The reliability of a pressure algometer 

      Knapstad, Mari Kalland; Nordahl, Stein Helge; Naterstad, Ingvill Fjell; Ask, Tove; Skouen, Jan Sture; Goplen, Frederik Kragerud (Peer reviewed; Journal article, 2018)

    • Neck pain associated with clinical symptoms in dizzy patients- A cross-sectional study 

      Knapstad, Mari Kalland; Glad Nordahl, Stein Helge; Skouen, Jan Sture; Ask, Tove; Goplen, Frederik Kragerud (Peer reviewed; Journal article, 2020)
      Objective: Many patients suffer from concurrent neck pain and dizziness. The aim of this study was to describe the clinical symptoms and physical findings in patients with concurrent neck pain and dizziness and to examine ...
    • Postural control in a simulated saturation dive to 240 msw. 

      Goplen, Frederik Kragerud; Aasen, T. B.; Nordahl, Stein Helge G. (Peer reviewed; Journal article, 2007)
      INTRODUCTION: There is evidence that increased ambient pressure causes an increase in postural sway. This article documents postural sway at pressures not previously studied and discusses possible mechanisms. METHODS: Eight ...
    • The Risk of Benign Paroxysmal Positional Vertigo After Head Trauma 

      Andersson, Helene; Jablonski, Greg Eigner; Nordahl, Stein Helge Glad; Nordfalk, Karl; Helseth, Eirik; Martens, Camilla; Røysland, Kjetil; Goplen, Frederik Kragerud (Journal article; Peer reviewed, 2021)
      Objectives: Head trauma may cause dislodgement of otoconia and development of benign paroxysmal positional vertigo (BPPV). The risk of developing BPPV is expected to be highest shortly after the trauma, then decrease and ...
    • Treatment of horizontal canal BPPV—a randomized sham-controlled trial comparing two therapeutic maneuvers of different speeds 

      Martens, Camilla; Goplen, Frederik Kragerud; Aasen, Torbjørn; Gjestad, Rolf; Nordfalk, Karl Fredrik; Nordahl, Stein Helge Glad (Journal article; Peer reviewed, 2020)
