Immediate effects of spinal manipulative therapy on clinical and biomechanical outcomes in participants with chronic thoracic pain.

[Update] The objective of this study is twofold. Data from four separate cross-sectional studies were analyzed together in order to compare participant characteristics, such as anthropometrics, age and gender with spinal stiffness. A secondary objective explores differences in outcome measures obtained with different spinal stiffness testing devices and protocols. Lead: Isabelle Pagé 



centre of rotation study

A scoping review looking at biomechanical testing investigating the center of rotation location on the lumbar spine is currently being conducted. From the results of this scoping review, a biomechanical testing study will be designed to investigate the influence of center of rotation location on the forces experienced by spinal tissues. Lead: Martha Funabashi

Challenges and lessons for recruitment within chiropractic studies

An analysis of recruitment and retention data from three studies, a narrative discussion on challenges of recruitment and potential suggestions for future studies. Lead: Michelle Holmes

Common mechanical themes among persons referred for Objective Spine Motion Imaging Assessment

A retrospective analysis of existing spinal kinematic data from AECC University College’s Quantitative Fluoroscopy database will be used to determine common mechanical themes among persons referred for Objective Spine Motion Imaging Assessment (OSMIA). Data collection is well under way with motion data from 52 participants collated. Lead: Alex Breen

Does lower limb joint pain increase the risk of low back pain in older women?

This study will use the Australian longitudinal study on women’s health data to explore whether the presence of lower limb joint pain is associated with a higher prevalence and severity of low back pain. Introduction has been drafted and we are currently conducting data analysis. Lead: Arnold Wong

Risk stratification and long-term clinical course after an initial manual treatment package for patients with low back pain

Using data from a randomized controlled trial; this secondary analysis will analyze psychological subgroups data trajectories. Lead: Andreas Eklund


Lifestyle factors that influence headaches in school children

The purpose of this study it to identify lifestyle factors of school-aged children that affect headaches in this population. Lead: Craig Moore


SafetyNET Investigations – Advancing patient safety research for SMT providers

This work involves a series of projects, with current focus on the implementation of developed data collection instruments. The population has been done within a chiropractic teaching institute. Plans are to reach out to practicing doctors on an international platform. The projects include: 1) Determine the incidence of mild, moderate, and serious adverse events following SMT administered by chiropractic interns using the SafetyNET active surveillance reporting system in teaching clinics and community-based practices. 2) Qualitative evaluation of open-ended questions on SafetyNET’s Survey to Support Quality Improvement. Lead: Martha Funabashi and Katie Pohlman

Systematic Review and Meta-Analysis investigating the relationship between objectively measured sitting time and low back pain in adults

Current evidence suggests that self-reported sitting time substantially underestimates actual sitting time when measured objectively (activity monitor, other sensor or direct observation).  This project will involve a systematic review of literature, and if possible a meta-analysis of pooled data, to answer the following question: in adults, are longer periods of objectively measured sitting time associated with back pain (perceived ratings of pain, health care visits, lost days of work) compared to shorter periods of sitting time? This manuscript is currently under review and received the First Prize Award at WFC/ECU EPIC Conference 2019. Lead: Diana De Carvalho



The profile of chiropractors managing older patients: Analyses of chiropractors from the ACORN practice-based research network

The aim of the current project is to determine practitioner and practice-related factors associated with the frequent treatment of older people by Australian chiropractors, using a large nationally representative sample of Australian chiropractors. Lead: Craig Moore

What’s behind the development of Transient Sitting-Induced Back Pain in Healthy Participants?

Using data from a laboratory controlled study; this study will explore the qualitative factors that may explain why some individuals, with no history of low back pain, develop transient back pain during prolonged sitting. Statistical analysis and results figures have been completed, manuscript to move forward in the fall. Lead: Diana De Carvalho



The risk factors for low back pain in older adults: A systematic review

A systematic review of the literature to identify risk factors associated with low back pain in community-dwelling older adults. Lead: Arnold Wong

Physical activity endorsement by Australian chiropractors: analyses of 1,924 from the ACORN practice-based research network

Apart from the management of spinal pain, chiropractors are also recognised as advocates for active lifestyle promotion, with at least 90% prescribing or advising on physical activity throughout their consultations. Indeed, the chiropractic profession is ideally positioned to promote the health benefits of physical activity, yet the knowledge about the role these providers play regarding the management of this lifestyle-related risk factor is limited, particularly regarding their clinical characteristics. The aim of this current study is to therefore understand the role Australian chiropractors play within this public health field, by investigating their practitioner, practice and patient management features with respect to physical activity recommendations. Manuscript currently under review. Lead: Matt Fernandez



Chiropractic student identity: a global secondary data analysis

A secondary data analysis of surveys surrounding identity of European, North American, Australian and New Zealand chiropractic students. Lead: Michelle Holmes

Apportionment of lumbar intervertebral motion in a standardized flexion and return protocol using fluoroscopy: basic data to improve current spine models

Recent studies using standardized image acquisition protocols have indicated that the sharing of motion between lumbar levels during bending may be a mechanical marker in low back pain. To support future comparative studies, this project aims to outline a standardized protocol and to identify the how continuous intervertebral motion for L2-S1 during weight-bearing flexion and return in 78 asymptomatic individuals is taken up by each functional spinal unit. The use of quantitative fluoroscopy allows for continuous accurate in-vivo intervertebral lumbar spine motion measurement, the outputs of which are critical to inform dynamic multi-segmental spinal models and for comparisons in patients with low back pain which is suspected to have a mechanical origin.

Attitudes and Beliefs of Chronic Low Back Pain of Faculty and Students at a Chiropractic Institution: a cross-sectional survey

To assess the attitudes and beliefs of students and faculty of a chiropractic teaching institution using the Health Care Providers’ Pain and Impairment Relationship Scale (HC-PAIRS) and evaluate their recommendations for work and activity in patients with chronic low back pain. Data has been collected and manuscript in preparation. Lead: Katie Pohlman
