Magnetic resonance imaging of the knee in Norway 2002–2004 (national survey): rapid increase, older patients, large geographic differences
Espeland, Ansgar; Natvig, Nils L.; Løge, Ingard; Engebretsen, Lars; Ellingsen, Jostein (Peer reviewed; Journal article, 2007-07-22)Background: Magnetic resonance imaging (MRI) of the knee is the second most common MRI examination in Norway after head/brain MRI. Little has been published internationally on trends in the use of knee MRI after 1999. This ... -
Minimal important change was on the lower spectrum of previous estimates and responsiveness was sufficient for core outcomes in chronic low back pain
Bråten, Lars Christian Haugli; Grøvle, Lars; Wigemyr, Monica; Wilhelmsen, Maja; Gjefsen, Elisabeth; Espeland, Ansgar; Haugen, Anne Julsrud; Skouen, Jan Sture; Brox, Jens Ivar; Zwart, John Anker Henrik; Storheim, Kjersti; Ostelo, Raymond WJG.; Grotle, Margreth (Journal article; Peer reviewed, 2022)Objectives: The objective of this study was to estimate the minimal important change (MIC) and responsiveness of core patient reported outcome measures for chronic low back pain (LBP) and Modic changes. Study Design and ... -
Modic changes-Their associations with low back pain and activity limitation: A systematic literature review and meta-analysis
Herlin, Christofer; Kjær, Per; Espeland, Ansgar; Skouen, Jan Sture; Leboeuf-Yde, Charlotte; Karppinen, Jaro; Niinimäki, Jaakko; Sørensen, Joan Solgaard; Storheim, Kjersti; Jensen, Tue Secher (Peer reviewed; Journal article, 2018-08-01)Background: Previous systematic reviews have reported positive associations between Modic changes (MCs) and low back pain (LBP), but due to their narrow scope and new primary studies, there is a need for a comprehensive ... -
No effect of 6-month intake of glucosamine sulfate on Modic changes or high intensity zones in the lumbar spine: sub-group analysis of a randomized controlled trial
Wilkens, Philip; Storheim, Kjersti; Scheel, Inger; Berg, Linda; Espeland, Ansgar (Peer reviewed; Journal article, 2012-08-17)Background: The underlying pathology and natural course of Modic changes (MC) in the vertebral body marrow and high intensity zones (HIZs) in the annulus fibrosus is not completely clarified. These findings on magnetic ... -
A novel MRI index for paraspinal muscle fatty infiltration: reliability and relation to pain and disability in lumbar spinal stenosis: results from a multicentre study
