Journal ArticleDOI
Measurement of intervertebral motion using quantitative fluoroscopy: report of an international forum and proposal for use in the assessment of degenerative disc disease in the lumbar spine.
TL;DR: The Forum recommended that images should be acquired during regular trunk motion that is controlled for velocity and range, in order to minimise externally imposed variability as well as to correlate intervertebral motion with trunk motion.
Journal ArticleDOI
Association of Exposures to Seated Postures With Immediate Increases in Back Pain: A Systematic Review of Studies With Objectively Measured Sitting Time
Diana De Carvalho,Katie de Luca,Martha Funabashi,Alexander Breen,Arnold Y.L. Wong,Melker S Johansson,Manuela L. Ferreira,Michelle Swab,Gregory N. Kawchuk,Jon Adams,Jan Hartvigsen +10 more
TL;DR: It is recommended that future prospective studies should match objectively measured sitting with temporally related pain measurements to determine whether prolonged sitting can trigger a clinical episode of LBP.
Journal ArticleDOI
Uneven intervertebral motion sharing is related to disc degeneration and is greater in patients with chronic, non-specific low back pain: an in vivo, cross-sectional cohort comparison of intervertebral dynamics using quantitative fluoroscopy
Alan Breen,Alexander Breen +1 more
TL;DR: Greater inequality and variability of motion sharing was found in patients with CNSLBP than in controls, confirming previous studies and suggesting a biomechanical marker for the disorder at intervertebral level.
Journal ArticleDOI
Estimation of in vivo inter-vertebral loading during motion using fluoroscopic and magnetic resonance image informed finite element models.
TL;DR: The results demonstrate that MR and QF data can be combined in a participant-specific FE model to investigate spinal biomechanics in vivo and that predicted stresses are within ranges reported in the literature.
Journal ArticleDOI
Intrasubject repeatability of in vivo intervertebral motion parameters using quantitative fluoroscopy.
TL;DR: Disc height and IV-RoM measurement using QF could be considered for randomised trials, while laxity, MSI and translation could be consideration for moderators, correlates or mediators of patient-reported outcomes.
