Rheumatoid arthritis (RA) is a relentless condition that affects more than half a million Australians, often robbing people of their independence, mobility, and quality of life.
For those living with chronic pain and limited movement, the prospect of new management strategies is always of great interest.
Medical research continuously seeks innovative ways to alleviate suffering and enhance the daily lives of individuals facing such persistent health challenges.
But a new study from the University of South Australia is shining a hopeful light at the end of the tunnel, offering a fresh approach to managing this debilitating disease—one that could change the way we think about exercise and pain relief for RA sufferers.
A new way to exercise: Blood flow restricted resistance training
The research, funded by Arthritis Australia, explored the benefits of a novel exercise technique called blood flow restricted (BFR) resistance training.
If you’re picturing something out of a sci-fi movie, you’re not far off! This method involves placing a pneumatic cuff—similar to the one used for measuring blood pressure—around the top of the working limb.
The cuff is then inflated to restrict blood flow out of the limb, creating a unique environment that makes your muscles work harder, even when you’re lifting lighter weights.
Why is this important? For people with RA, traditional resistance training with heavy weights can be daunting, painful, or even risky.
The inflammation and joint pain that come with RA often make it difficult to perform standard strength exercises. BFR training, however, allows for significant muscle engagement and strength gains without the need for heavy lifting.
What did the study find?
Participants in the study performed five key exercises—leg press, machine hamstring curl, machine knee extension, cable tricep extension, and cable bicep curl—using gradually increasing weights, all while wearing the BFR cuffs.
The results were impressive: not only did participants report improvements in strength and physical performance, but they also experienced a reduction in pain.
Even more encouraging, every participant said they ‘liked’ the program—a rare feat in the world of exercise studies!
Dr Hunter Bennett, the lead researcher, explained the significance: ‘RA can cause a loss of muscle mass and strength, which affects day-to-day activities, independence, and increases the risk of falls and fractures.
Resistance training is one of the best ways to rebuild that strength, but for people with RA, using heavy weights can be difficult or harmful due to pain, fatigue or injury risk. This is where blood flow restricted resistance training can help.’
Why does this matter?
For many living with RA, the idea of exercise can be intimidating. Pain, fatigue, and the fear of injury often keep people from moving as much as they’d like.
But as Dr Bennett points out, exercise is often one of the best things you can do to manage RA and improve your overall health.
BFR training offers a practical, achievable, and less intimidating way to build strength and reduce pain—without having to ‘push through’ discomfort.
‘This kind of training could be a game-changer for people with rheumatoid arthritis,’ Dr Bennett says.
‘It offers a way to build strength and reduce pain without pushing through discomfort – and that’s incredibly empowering for people who’ve often been limited by their condition.’
How does blood flow restricted training work?
The science behind BFR training is fascinating. By restricting blood flow, the muscles are forced to work in a low-oxygen environment, which triggers a cascade of beneficial effects.
Even with lighter weights, the muscles respond as if they’re lifting much heavier loads, leading to increased strength and muscle growth.
This is particularly valuable for people with RA, who may not be able to tolerate traditional weightlifting.
What’s next?
While this was a small-scale trial, the results are promising. The researchers are now laying the groundwork for a larger study to compare BFR resistance exercise with more traditional exercise approaches.
If these findings hold up, BFR training could soon become a standard part of RA management, helping thousands of Australians regain strength, confidence, and independence.
Other promising developments in RA management
It’s worth noting that this study is part of a broader trend towards more holistic and personalised approaches to managing RA.
Alongside medication, lifestyle changes such as diet, stress management, and tailored exercise programs are increasingly recognised as vital components of effective RA care.
Innovations like BFR training add another tool to the toolkit, giving people more options to find what works best for them.
A word of caution
As with any new exercise program, especially one involving specialised equipment, it’s important to consult with your healthcare provider or a qualified physiotherapist before starting BFR training. Proper supervision and guidance are essential to ensure safety and maximise benefits.
