New exercise test aims to improve the quality of life of people with rheumatoid arthritis
Rheumatoid arthritis is an inflammatory disease that can cause severe pain and swelling of the joints. But a new exercise intervention could help improve physical function and quality of life in people struggling with this debilitating condition.
In a new trial, researchers from the University of South Australia are working with Arthritis SA to investigate the potential of Blood Flow Restriction (BFR) training to improve the strength and mobility of people with rheumatoid arthritis.
BFR training is an exercise technique in which people wear pressurized bands – much like blood pressure cuffs – to slow blood flow to the muscles while they exercise. The cuff allows blood flow to the limb but slows its outflow, developing muscle strength without the need for heavy weights.
In Australia, rheumatoid arthritis is the second most common form of arthritis, affecting more than 450,000 people. More than 18 million people worldwide live with a condition. Women are two to three times more likely to develop rheumatoid arthritis than men.
Sports scientist Dr. UniSA’s Hunter Bennett says the research hopes to identify interventions that can improve the quality of life for people with rheumatoid arthritis.
“Rheumatoid arthritis can be a particularly debilitating disease. It is caused by the immune system attacking healthy tissues, leading to pain and swelling, joint destruction and loss of muscle mass and strength,” says Dr. Bennett.
Although medications can reduce symptoms, they do not address the loss of muscle strength and function.
The best way to increase strength and combat muscle loss is through resistance training, but this is often problematic for people with rheumatoid arthritis due to pain, fatigue or risk of injury.
Blood flow restriction training (BFR) offers an alternative. BRF is used in many sports and rehabilitation settings in Australia and is considered a safe and effective method for improving strength and function in many clinical populations, including people with osteoarthritis.
Because this technique uses very low loads, it is a viable option for people with rheumatoid arthritis. So in our research we look at how BRF can increase people’s strength and hopefully increase their freedom of movement and overall well-being.”

The research team is currently seeking expressions of interest from women and men aged 45 to 75 years diagnosed with rheumatoid arthritis.
