      Background: Left vocal cord paralysis (LVCP) is a known complication of patent ductus arteriosus (PDA) surgery in extremely preterm (EP) born neonates; however, consequences of LVCP beyond the first year of life are ...
    • 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. ...
    • Predicting physical activity in a national cohort of children born extremely preterm 

      Engan, Mette; Engeseth, Merete Salveson; Fevang, Silje Katrine Elgen; Vollsæter, Maria; Eide, Geir Egil; Røksund, Ola Drange; Halvorsen, Thomas; Clemm, Hege Havstad (Peer reviewed; Journal article, 2020)
