      Dynamic obstructions of the larynx are a set of disorders that occur during exercise in equines and humans. There are a number of similarities in presentation, diagnosis, pathophysiology and treatment. Both equines and ...
    • Exercise inducible laryngeal obstruction: diagnostics and management 

      Røksund, Ola Drange; Heimdal, John-Helge; Clemm, Hege Synnøve Havstad; Vollsæter, Maria; Halvorsen, Thomas (Peer reviewed; Journal article, 2017-01)
      Obstruction of the central airways is an important cause of exercise-induced inspiratory symptoms (EIIS) in young and otherwise healthy individuals. This is a large, heterogeneous and vastly understudied group of patients. ...
    • Exercise-induced laryngeal obstruction in athletes treated with inspiratory muscle training

      Background Exercise-induced laryngeal obstruction (EILO) is common in athletes and presents with dyspnoea, chest tightness, inspiratory stridor and sometimes panic reactions. The evidence for conservative treatment is weak, ...
    • Feasibility and tolerability of measuring translaryngeal pressure during exercise 

      Kelly, Zoe Louise; Halvorsen, Thomas; Heimdal, John-Helge; Strand, Eric; Vollsæter, Maria; Clemm, Hege Synnøve Havstad; Røksund, Ola Drange (Peer reviewed; Journal article, 2019)
      Objectives/Hypothesis: To determine if simultaneous tracheal and supraglottic pressure measurement performed during a continuous laryngoscopy exercise (CLE) test is possible, tolerable, and feasible, and if so, whether ...
    • Laryngeal response patterns influence the efficacy of mechanical assisted cough in amyotrophic lateral sclerosis 

      Andersen, Tiina Maarit; Sandnes, Astrid; Brekka, Anne Kristine; Hilland, Magnus; Clemm, Hege; Fondenes, Ove; Tysnes, Ole Bjørn; Heimdal, John-Helge; Halvorsen, Thomas; Vollsæter, Maria; Røksund, Ola Drange (Peer reviewed; Journal article, 2017)
      Background: Most patients with amyotrophic lateral sclerosis (ALS) are treated with mechanical insufflation–exsufflation (MI-E) in order to improve cough. This method often fails in ALS with bulbar involvement, allegedly ...

      Vollsæter, Maria (Doctoral thesis, 2016-04-22)
      Background: Survival after extremely preterm (EP) birth has increased considerably during the last three decades. The lifetime respiratory prospects for survivors are unknown. Aim: To study long-term respiratory health ...
    • Physiotherapy improves symptoms of exercise-induced laryngeal obstruction in young elite athletes: A case series 

      Kolnes, Liv-Jorunn; Vollsæter, Maria; Røksund, Ola Drange; Stensrud, Trine (Peer reviewed; Journal article, 2019)
      Objective: A constricted, upper chest breathing pattern and postural dealignments habitually accompany exercise-induced laryngeal obstruction (EILO), but there are few effective treatments for athletes presenting with EILO. ...
