Rheumatoid arthritis (RA) is not wear and tear. It is an autoimmune condition: the immune system attacks the lining of the joints, producing inflammation that, untreated, damages cartilage and bone. It typically starts in the small joints of the hands and feet, often symmetrically, with pain, swelling, and morning stiffness that lasts an hour or more. Fatigue is part of it too, and a feature people underestimate.
Two things need saying up front. First, RA requires medical treatment, disease-modifying drugs have transformed what this condition does to people, and starting them early changes the long-term outcome. That is your rheumatologist’s domain and it is not optional. Second, within that medical treatment, movement is not a nice extra. It is part of the therapy, and the older instinct to rest inflamed joints into weakness has been tested and found wrong.
What the exercise evidence shows
Cochrane reviewed dynamic exercise programs in RA, aerobic capacity training and muscle strength training, across eight trials with 575 participants. The conclusion: these programs are safe for people with RA, improve aerobic capacity and muscle strength, and, when continued over the longer term, improve functional ability. The reviewers recommended aerobic training combined with strength training as routine practice. Notably, exercise did not worsen disease activity or joint damage in these trials, the fear that loading inflamed joints would harm them was not borne out.
What physiotherapy works on
- Strength training, dosed to the day. RA fluctuates. On settled days, progressive resistance work builds the muscle that protects joints and fights the weakness and bone loss that come with the condition and some of its medications. On flare days, the program scales down, range-of-motion and gentle isometrics, rather than disappearing.
- Aerobic exercise. Cycling, walking, pool work, people with RA carry higher cardiovascular risk, and aerobic fitness is part of managing the whole condition, not just the joints.
- Joint protection and energy management. Technique changes for gripping, lifting, and pacing the day that reduce stress on vulnerable joints, especially the hands, without wrapping life in cotton wool.
- Range of motion. Inflamed joints stiffen; daily movement through comfortable range defends the motion you have.
- Hands specifically. Structured hand exercise programs have their own supportive evidence in RA, and hands are where function is most personal, buttons, jars, keyboards, grandchildren.
Working with flares
A flare is not a failure and it is not a stop sign; it is a dose adjustment. The pattern that works: a day or two of gentler movement and relative rest for the angry joints, heat or cold as you prefer, then rebuilding as it settles. A flare that involves many joints at once, or one joint that is hot and severely painful, or fever alongside is a call to your medical team, it may be disease activity needing a medication change, or occasionally infection, which is more serious in people on immune-suppressing drugs.
The long game
RA is managed in years. The people who do best treat exercise the way they treat medication, as a standing part of the routine, adjusted rather than abandoned when the condition flares. Our role is building that routine with you, progressing it, and re-calibrating it as the disease and your life change.
