Rodrigo Rizzo
RESEARCHER PROFILE
PhD Candidate
Rodrigo Rizzo is a Doctoral Candidate at Neuroscience Research Australia (NeuRA) and University of New South Wales (UNSW). He is a physiotherapist who has worked in the management of chronic pain for over 15 years. Rod became interested in understanding the effect of clinical hypnosis for chronic pain, and in 2018, he published the first randomized controlled trial combining clinical hypnosis with pain neuroscience education.
Supervised by A/Prof James McAuley and A/Prof Sylvia Gustin, Rod is using quantitative and qualitative methods to investigate mechanisms of interventions for treating back pain. Using qualitative research, he wants to understand people’s beliefs about treatments that target the brain for the management of back pain. Using quantitative analysis, he investigates whether and how interventions designed to change the nervous system work in patients with pain. Rod’s current projects include:
- The reporting of mediation analysis in recently published observational studies: a systematic review
- The Role of Catastrophising in Chronic Low Back Pain: a Mediation Analysis from a Randomised Controlled Trial
- How do people with chronic low back pain perceive interventions that target the brain to reduce pain and disability? – A qualitative study
- Efficacy and safety of medicines targeting neurotrophic factors in the management of low back pain: a systematic review and meta-analysis.
Rod is the lead organiser of the Centre for Pain IMPACT (investigating mechanisms of pain to advance clinical translation), which is a collaboration of pain researchers at NeuRA, who have a focus on encompassing basic science through to clinical and translational research.

RESOLVE Trial for Chronic Low Back Pain
For people with long term back pain that is not getting better. We are testing two pain treatment programs that target the brain, for people with chronic low back pain.READ MORE
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:
- 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.
- 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.
- 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.
- 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.
- 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.
- 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:
- 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.
- 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.
