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.

CURRENT PROJECTS

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.

Medicines for Back Pain

Medicines are a common treatment for back pain. The aim of this program of research is to improve our understanding of the clinical effects of medicines. Several studies constitute this program. 
 
Studies: 
1. A scoping review of analgesic medicines for chronic low back pain
The objective of this study is to identify the available clinical trials of medicines for chronic low back pain.  
This information will contribute to the methodology of Study 3. 
 
2. Evaluation of the impact of unpublished data from clinical trial registries on the effects of medicines for low back pain. 
The objective of this study is to evaluate whether there is a difference between clinical trial data that are published and those that are not published. 
This information will contribute to the methodology of Study 3. 
 
3. Paracetamol, NSAIDs and opioid analgesics for chronic low back pain: a network meta-analysis. 
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.

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.
