Clinical responses following inspiratory muscle training in exercise-induced laryngeal obstruction
Sandnes, Astrid; Andersen, Tiina Maarit; Clemm, Hege Synnøve Havstad; Hilland, Magnus; Heimdal, John-Helge; Halvorsen, Thomas; Røksund, Ola Drange; Vollsæter, Maria (Journal article; Peer reviewed, 2021)Purpose Exercise-induced laryngeal obstruction (EILO) is relatively common in young people. Treatment rests on poor evidence; however, inspiratory muscle training (IMT) has been proposed a promising strategy. We aimed to ... -
Exercise-induced laryngeal obstruction: natural history and effect of surgical treatment
Maat, Robert Christiaan; Hilland, Magnus; Røksund, Ola Drange; Halvorsen, Thomas; Olofsson, Jan; Aarstad, Hans Jørgen; Heimdal, John-Helge (Peer reviewed; Journal article, 2011-06-05)The current follow-up study concerning the supraglottic type of exercise-induced laryngeal obstruction (EILO) was performed to reveal the natural history of supraglottic EILO and compare the symptoms, as well as the laryngeal ... -
Impact of EMG Changes in Continuous Vagal Nerve Monitoring in High-Risk Endocrine Neck Surgery
Brauckhoff, Katrin; Vik, Renate Kollevåg; Sandvik, Lorentz; Heimdal, John-Helge; Aas, Turid; Biermann, Martin; Brauckhoff, Michael (Peer reviewed; Journal article, 2016-03)Background: Continuous vagal intraoperative neuromonitoring (CIONM) of the recurrent laryngeal nerve (RLN) may reduce the risk of RLN lesions during high-risk endocrine neck surgery such as operation for large goiter ... -
In vitro-stimulated IL-6 monocyte secretion and in vivo peripheral blood T lymphocyte activation uniquely predicted 15-year survival in patients with head and neck squamous cell carcinoma
Aarstad, Helene Hersvik; Vintermyr, Olav Karsten; Ulvestad, Elling; Kross, Kenneth Wilfried; Heimdal, John-Helge; Aarstad, Hans Jørgen (Peer reviewed; Journal article, 2015-06-16)The study was performed in order to determine whether peripheral blood monocyte in vitro function, and lymphocyte in vivo activation at diagnosis, was associated with HPV tumor infection status and 15-year survival in head ... -
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 ... -
Larynx during exercise: the unexplored bottleneck of the airways
Røksund, Ola Drange; Heimdal, John-Helge; Olofsson, Jan; Maat, Robert; Halvorsen, Thomas (Peer reviewed; Journal article, 2014-07-18)Exercise-induced shortness of breath is not uncommon in otherwise healthy young people. Based on the presenting symptoms alone, it is challenging to distinguish exercise-induced asthma (EIA) from exercise-induced obstruction ...
