Breen, Alan; Muggleton, Jennifer M; Mellor, Fiona (BMC Musculoskeletal Disorders, 2006)Background: Minimally-invasive measurement of continuous inter-vertebral motion in clinical settings is difficult to achieve. This paper describes the reliability, validity and radiation exposure levels in a new Objective ... -
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
Breen, Alan; Teyhen, Deydre S; Mellor, Fiona; Breen, Alex; Wong, Kris W N; Deitz, Adam (Advances in Orthopedics, 2012)Quantitative fluoroscopy (QF) is an emerging technology for measuring intervertebral motion patterns to investigate problem back pain and degenerative disc disease.

Moving back: The radiation dose received from lumbar spine quantitative fluoroscopy compared to lumbar spine radiographs with suggestions for dose reduction
Mellor, Fiona; Thomas, P; Breen, Alan (Radiography, 2014)Purpose: Quantitative fluoroscopy is an emerging technology for assessing continuous inter-vertebral motion in the lumbar spine, but information on radiation dose is not yet available. The purposes of this study were to ... -
Does inter-vertebral range of motion increase after spinal manipulation? A prospective cohort study
Branney, Jonathan; Breen, Alan (Chiropractic and Manual Therapies, 2014)Background: Spinal manipulation for nonspecific neck pain is thought to work in part by improving inter-vertebral range of motion (IV-RoM), but it is difficult to measure this or determine whether it is related to clinical ... -
Proportional lumbar spine inter-vertebral motion patterns: a comparison of patients with chronic, non-specific low back pain and healthy controls
Mellor, Fiona; Thomas, P W; Thompson, P; Breen, Alan (2014)Introduction: Identifying biomechanical subgroups in chronic, non-specific low back pain (CNSLBP) populations from inter-vertebral displacements has proven elusive. Quantitative fluoroscopy (QF) has excellent repeatability ... -
Does cervical lordosis change after spinal manipulation for non-specific neck pain? A prospective cohort study
Shilton, Michael; Branney, Jonathan; Penning de Vries, Bas; Breen, Alan (Chiropractic and Manual Therapies, 2015)Background: The association between cervical lordosis (sagittal alignment) and neck pain is controversial. Further, it is unclear whether spinal manipulative therapy can change cervical lordosis. This study aimed to determine ... -
Accuracy and repeatability of quantitative fluoroscopy for the measurement of sagittal plane translation and finite centre of rotation in the lumbar spine
Breen, Alex; Breen, Alan (Medical Engineering and Physics, 2016)Quantitative fluoroscopy (QF) was developed to measure intervertebral mechanics in vivo and has been found to have high repeatability and accuracy for the measurement of intervertebral rotations. However, sagittal plane ... -
Relationships between paraspinal muscle activity and lumbar inter-vertebral range of motion
du Rose, Alister; Breen, Alan (Healthcare, 2016)Control of the lumbar spine requires contributions from both the active and passive sub-systems. Identifying interactions between these systems may provide insight into the mechanisms of low back pain. However, as a first ... -
Relationships between lumbar inter-vertebral motion and lordosis in healthy adult males: a cross sectional cohort study
du Rose, Alister; Breen, Alan (BMC Musculoskeletal Disorders, 2016)Background: Intervertebral motion impairment is widely thought to be related to chronic back disability, however, the movements of inter-vertebral pairs are not independent of each other and motion may also be related to ... -
Low back pain: Identifying sub-groups, clinical prediction rules and measuring results
Breen, Alan (Complementary Therapies in Clinical Practice, 2018)Low back pain is a complex, multifactorial health problem with huge socioeconomic impact. The purpose of this brief review was to reconsider the use of the biopsychosocial model as a basis for subgrouping cases to support ... -
Anti-directional cervical intervertebral motion: could it have gone any other way?
Breen, Alan (Journal of Spine Surgery, 2018) -
Estimation of in vivo inter-vertebral loading during motion using fluoroscopic and magnetic resonance image informed finite element models
Zanjani-Pour, Sahand; Meaking, Judith R; Breen, Alex; Breen, Alan (Journal of Biomechanics, 2018)Finite element (FE) models driven by medical image data can be used to estimate subject-specific spinal biomechanics. This study aimed to combine magnetic resonance (MR) imaging and quantitative fluoroscopy (QF) in ... -
Relationships between muscle electrical activity and the control of inter-vertebral motion during a forward bending task
du Rose, Alister; Breen, Alex; Breen, Alan (Journal of Electro - myography and Kinesiology, 2018)Muscle strengthening exercises are commonly used in primary care for the treatment of chronic, non-specific low back pain (CNSLBP) as it has been theorised that increased muscle activity contributes to the stabilisation ... -
Aberrant intervertebral motion in patients with treatment-resistant nonspecific low back pain: a retrospective cohort study and control comparison
Breen, Alex; Mellor, Fiona; Breen, Alan (European Spine Journal, 2018)Purpose: Intervertebral kinematic assessments have been used to investigate mechanical causes when back pain is resistant to treatment, and recent studies have identified intervertebral motion markers that discriminate ... -
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
Breen, Alan; Breen, Alex (European Spine Journal, 2018)Purpose: Evidence of intervertebral mechanical markers in chronic, non-specific low back pain (CNSLBP) is lacking. This research used dynamic fluoroscopic studies to compare intervertebral angular motion sharing inequality ... -
Manual therapy
Breen, Alan; Vogel, Steven; McCarthy, Christopher (International Society for the Study of the Lumbar Spine, 2018)Manual therapy (MT) is a very common practice among primates and its range of uses and the variety of techniques is probably infinite.
