    • Arm Crank and Wheelchair Ergometry Produce Similar Peak Oxygen Uptake but Different Work Economy Values in Individuals with Spinal Cord Injury 

      Tørhaug, Tom; Brurok, Berit; Hoff, Jan; Helgerud, Jan; Leivseth, Gunnar (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-03-20)
      <i>Objective. </i> To study whether values for peak oxygen uptake (VO<sub>2peak</sub>) and work economy (WE) at a standardized workload are different when tested by arm crank ergometry (ACE) and wheelchair ergometry (WCE). <i>Methods. </i> Twelve paraplegic men with spinal cord injury (SCI) in stable neurological condition participated in this cross-sectional repeated-measures study. We determined ...

    • Change in pain, disability and influence of fear-avoidance in a work-focused intervention on neck and back pain: a randomized controlled trial 

      Marchand, Gunn Hege; Myhre, Kjersti; Leivseth, Gunnar; Sandvik, Leiv; Lau, Bjørn; Bautz-Holter, Erik; Røe, Cecilie (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-04-21)
      Background: Neck and back pain are among the most common causes of prolonged disability, and development of interventions with effect on pain, disability and return to work is important. Reduction of fear avoidance might be one mechanism behind improvement after interventions. The aim of the present study was to evaluate changes in pain and disability at the 12-month follow-up of patients with neck ...

    • Comparison of the SF6D, the EQ5D, and the oswestry disability index in patients with chronic low back pain and degenerative disc disease 

      Johnsen, Lars Gunnar; Hellum, Christian; Nygaard, Øystein Petter; Storheim, Kjersti; Brox, Jens Ivar; Rossvoll, Ivar; Leivseth, Gunnar; Grotle, Margreth (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Background: The need for cost effectiveness analyses in randomized controlled trials that compare treatment options is increasing. The selection of the optimal utility measure is important, and a central question is whether the two most commonly used indexes - the EuroQuol 5D (EQ5D) and the Short Form 6D (SF6D) – can be used interchangeably. The aim of the present study was to compare change ...

    • Effect of lower extremity functional electrical stimulation pulsed isometric contractions on arm cycling peak oxygen uptake in spinal cord injured individuals 

      Brurok, Berit; Tørhaug, Tom; Karlsen, Trine; Leivseth, Gunnar; Helgerud, Jan; Hoff, Jan (Journal article; Tidsskriftartikkel; Peer reviewed, 2013-01-11)
      <p><i>Objective - </i>To compare peak oxygen uptake (VO<sub>2peak</sub>) between: (<i>i</i>) functional electrical stimulation lower extremity pulsed isometric muscle contractions combined with arm cycling (FES iso hybrid), (<i>ii</i>) functional electrical stimulation cycling combined with arm cycling (FES hybrid cycling), and (<i>iii</i>) arm cycling exercise (ACE) in individuals with spinal cord ...

    • Physical examination tests of the shoulder: a systematic review and meta-analysis of diagnostic test performance 

      Gismervik, Sigmund Østgård; Drogset, Jon Olav; Granviken, Fredrik; Rø, Magne; Leivseth, Gunnar (Peer reviewed; Journal article; Tidsskriftsartikkel, 2017-01-25)
      Background: Physical examination tests of the shoulder (PETS) are clinical examination maneuvers designed to aid the assessment of shoulder complaints. Despite more than 180 PETS described in the literature, evidence of their validity and usefulness in diagnosing the shoulder is questioned. Methods: This meta-analysis aims to use diagnostic odds ratio (DOR) to evaluate how much PETS shift ...

    • Protein homeostasis in LGMDR9 (LGMD2I) – The role of ubiquitin‐proteasome and autophagy‐lysosomal system 

      Franeková, Veronika; Storjord, Hilde, I.; Leivseth, Gunnar; Nilssen, Øivind (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-18)
      Aims: Limb-girdle muscular dystrophy R9 (LGMDR9) is an autosomal recessive disorder caused by mutations in the fukutin-related protein gene (FKRP), encoding a glycosyltransferase involved in α-dystroglycan modification. Muscle atrophy, a significant feature of LGMDR9, occurs by a change in the normal balance between protein synthesis and protein degradation. The ubiquitin–proteasome system (UPS) ...
