Understanding how the brain is involved in chronic pain

WHAT WE KNOW

One in five Australians experience chronic pain that is serious enough to disable them, costing the country approximately $35 billion a year. People who experience chronic pain (pain that continues for more than three months) often struggle to find effective treatment, and can experience disability and even depression.

We are conducting research into the nature of chronic pain, looking at the role of our brain in the experience of persistent pain, and changes in the central nervous system that may also occur.

We are also investigating why some people develop excessive pain in response to injury, developing a disorder called Complex Regional Pain Syndrome.

Medicines for Back Pain

MATTHEW BAGG, ASSOCIATE PROFESSOR JAMES MCAULEY, PAULINE ZAHARA, ANIKA HAIGH, EDEL O’HAGAN, AIDAN CASHIN, THIAGO FOLLY, DR MARKUS HUEBSCHER

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 Evaluation of the impact of unpublished data from clinical trial registries on the effects of medicines for low back pain.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.

SLEEPAIN

ASSOCIATE PROFESSOR JAMES MCAULEY, EDEL O’HAGAN

For people with back pain who are having trouble with their sleep. We are testing whether a simple sleep tablet will help people reduce their pain and sleep better.

RESOLVE - RECRUITING NOW

ASSOCIATE PROFESSOR JAMES MCAULEY, MATTHEW BAGG

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.

PREVENT

ASSOCIATE PROFESSOR JAMES MCAULEY, PROFESSOR LORIMER MOSELEY

For people with a new low back pain episode. We are testing early intervention to reduce the risk of developing chronic low back pain.

Identifying cortical and subcortical sites responsible for the divergent sympathetic responses to long-lasting muscle pain

PROFESSOR VAUGHAN MACEFIELD

We are trying to identify how a constant sensory input (muscle pain) causes two divergent patterns of sympathetic response: an increase in MSNA and blood pressure in some individuals and a decrease in others.

The effects of tonic muscle pain on the sympathetic and somatic motor systems

DR INGVARS BIRZNIEKS

Chronic pain, defined as pain lasting for >3 months, typically develops from injuries to deep tissues such as muscle, yet little is known about how long-lasting pain affects a person’s blood pressure or capacity to control their muscles. This project assesses the effects of tonic muscle pain on sympathetic nerve activity and stretch sensitivity of muscle spindles.

EP 38 - Low back pain with A/Prof James McAuley

Associate Professor James McAuley, says the Australian Government’s Therapeutic Goods Administration’s rescheduling of over the counter opioids is a positive step in curbing opioid addiction, but it is now more important than ever for clinicians and patients to be aware of opioid-free treatment options for chronic pain. “Drugs are a great solution to pain for the first one to two […]
