RESEARCHER PROFILE

Doctoral Candidate

+61 2 9399 1806


Aidan Cashin is a Doctoral Candidate at Neuroscience Research Australia (NeuRA). A member of the pain research group headed by Dr James McAuley, his research deals with investigating the mechanisms of treatments for chronic low back pain. He is also interested in increasing the openness and transparency of research and is involved in developing a reporting guideline for studies that use mediation analysis.

Prior to commencing research, Aidan pursued a successful clinical career as an Accredited Exercise Physiologist, practicing primarily in the field of chronic musculoskeletal pain. Aidan also has a casual academic position at the University of New South Wales, within the School of Medical sciences and is involved in the teaching and evaluating of undergraduate exercise physiology students.

Projects Aidan Cashin is currently involved with

CURRENT PROJECTS

MEMOIR – a clinical trial for Complex Regional Pain Syndrome

Complex Regional Pain Syndrome (CRPS) is a serious health condition, affecting approximately 20,000 people in Australia. It is characterised by severe burning, stinging and stabbing pain. People with CRPS are unable to use their painful limb and their ability to work or participate in normal social activities is severely restricted. Currently, there are no effective treatments for CRPS.

A vast body of research has demonstrated changes in brain processes in CRPS. The MEMOIR trial will investigate the effectiveness of two novel brain-directed treatments to reduce pain and improve function in people with CRPS.

MEMOIR consolidates the expertise of scientists and clinicians from NeuRA (A/Prof James McAuley, A/Prof Sylvia Gustin, Mr Michael Ferraro), the University of South Australia (Prof Lorimer Moseley), the University of Sydney (Prof Andrew McLachlan), the University of Notre Dame Australia Fremantle (Prof Benedict Wand, Prof Eric Visser), the University of Exeter (Prof Sallie Lamb), Brunel University London (Dr Neil O’Connell) and the University of Oxford (Dr Hopin Lee).

Due to the COVID-19 global pandemic, the commencement of MEMOIR has been delayed. Recruitment for MEMOIR will commence in September 2020.

If you are interested in being contacted about our CRPS research, please leave your details below and we will be in touch once recruitment begins.

RESOLVE Trial for Chronic Low Back Pain

Medicines for Back Pain

Medicines are the most common treatment for back pain. The aim of this program of research is to improve our understanding of the clinical effects of medicines.

Studies currently in progress:

  1. Scoping review of paracetamol, NSAIDs and opioid analgesics for chronic low back pain (led by Matthew K Bagg). The objective of this study is to identify and describe the characteristics of available clinical trials of commonly used analgesic medicines for chronic low back pain. This information will inform the design and conduct of other studies in the research program.
  2. Paracetamol, NSAIDs and opioid analgesics for chronic low back pain: a network meta-analysis (led by Matthew K Bagg). The objective of this study is to produce information about the clinical effects of available analgesic medicines for chronic low back pain. This information will be available in a Cochrane review to assist clinical prescription of medicines. The protocol is published and available here.
  3. Prescribing practices of medicines for adults with low back pain: a systematic review (led by Michael Wewege). The objective of this study is to determine how different medicines are prescribed to adults with low back pain and how this differs across countries. The protocol for this study is being developed.
  4. Analgesic medicines for adults with low back pain: a network meta-analysis (led by Michael Wewege). The objective of this study is to evaluate the comparative effectiveness of a range of analgesic medicines for adults across different classifications of low back pain. The protocol for this study has been submitted for publication.
  5. Muscle relaxant medicines for low back pain: a systematic review and meta-analysis (led by Aidan Cashin and Thiago Folly). The objective of this study is to determine the effectiveness and tolerability of muscle relaxant medicines for adults with low back pain. The protocol is available here.
  6. Novel biologic medicines for low back pain: a systematic review and meta-analysis (led by Rodrigo Rizzo). The objective of this study is to determine the effectiveness and tolerability of novel biologic medicines for adults with low back pain. The protocol is available here.

Completed studies:

  1. Evaluation of the impact of unpublished data from clinical trial registries on the effects of medicines for low back pain (led by Matthew Bagg). The objective of this study was to evaluate whether there is a difference between clinical trial data that are published and those that are not published. The findings are published in the Journal of Clinical Epidemiology.
  2. Antidepressant medicines for low back pain: a systematic review and meta-analysis (led by Michael Ferraro). The objective of this study was to determine the effectiveness and tolerability of antidepressant medicines for adults with low back pain. The findings have been submitted for publication. The protocol is available here.

AGReMA – A Guideline for Reporting Mediation Analyses

There are a growing number of studies using mediation analysis to understand the mechanisms of health interventions and exposures. Recent work has shown that the reporting of these studies is heterogenous and incomplete. This problem stifles clinical application, reproducibility, and evidence synthesis. The development and implementation of A Guideline for Reporting Mediation Analyses (AGReMA) will improve the standardization, transparency, and completeness in the reporting of studies that use mediation analysis to understand the mechanisms of health interventions and exposures.

Persistent Pain After Wrist or Hand Fracture: Development and Validation of a Prognostic Model.

Cashin AG, Traeger AC, Hübscher M, Moseley GL, di Pietro F, Parkitny L, McAuley JH

To develop and validate a prognostic model from a comprehensive range of candidate prognostic factors that can identify patients who are at risk of developing persistent pain following wrist or hand fracture. We developed and externally validated a prognostic model to predict persistent pain 4 months after a wrist or hand fracture. Future studies are needed to assess whether the accuracy of this model can be improved by updating and validating it in local settings.
