People challenged with chronic back pain have been given hope with a new treatment that focuses on retraining how the back and the brain communicate, a randomised controlled trial run by researchers at UNSW Sydney and Neuroscience Research Australia (NeuRA) and several other Australian and European universities has shown.
The study, funded by the Australian National Health and Medical Research Council (NHMRC), was described today in a paper published in the Journal of the American Medical Association. The study, carried out at NeuRA, divided 276 participants into two groups: one undertook a 12-week course of sensorimotor retraining and the other received a 12-week course of sham treatments designed to control for placebo effects, which are common in low back pain trials.
Professor James McAuley from UNSW’s School of Health Sciences, and NeuRA said sensorimotor retraining alters how people think about their body in pain, how they process sensory information from their back and how they move their back during activities.
“What we observed in our trial was a clinically meaningful effect on pain intensity and a clinically meaningful effect on disability. People were happier, they reported their backs felt better and their quality of life was better. It also looks like these effects were sustained over the long term; twice as many people were completely recovered. Very few treatments for low back pain show long-term benefits, but participants in the trial reported improved quality of life one year later.”
The new treatment challenges traditional treatments for chronic back pain, such as drugs and treatments that focus on the back such as spinal manipulation, injections, surgery and spinal cord stimulators, by viewing long-standing back pain as a modifiable problem of the nervous system rather than a disc, bone or muscle problem.
“If you compare the results to studies looking at opioid treatment versus placebo, the difference for that is less than one point out of 10 in pain intensity, it’s only short term and there is little improvement in disability. We see similar results for studies comparing manual therapy to sham or exercise to sham,” Prof. McAuley said.
