Exercise therapy
Larun's PhD involved a number of aspects of research into chronic fatigue syndrome, mostly in regard to the effects of exercise; she concluded chronic fatigue syndrome patients found exercise both enjoyable and beneficial, provided that it was guided by them and flexible. In addition, she found no adverse effects, although this study relied on only a small number of patients, with either mild or moderate symptoms.

Lillebeth Larun was lead author for the Cochrane Collaboration review of exercise therapy for chronic fatigue syndrome, which has faced extensive calls for retraction from both scientists and patients, particularly after the publication of the PACE trial data that the influenced the conclusions. In addition to scientific complaints made by professionals including Professor James Coyne, and by Robert Courtney, a patient with ME/CFS submitted a number of queries followed by a complaint containing a scientific critique of Larun et al's review,
