Rheumatoid Arthritis

Rheumatoid arthritis is an autoimmune disease in which the immune system attacks the lining of the joints. This is a different mechanism from osteoarthritis, where the joint surface wears. The distinction matters practically: RA is typically symmetrical, affects small joints of the hands and feet early, and produces morning stiffness lasting more than thirty minutes 1.

Untreated inflammation damages joints permanently, which is why medical treatment leads and rehabilitation runs alongside it rather than instead of it.

Medication controls the inflammation. Rehabilitation protects what the inflammation has already affected and preserves the function medication alone does not restore: hand function and grip, joint range, muscle strength lost through inactivity, and the daily activities that determine independence.

Occupational therapy is central here rather than peripheral. Joint protection technique, adapted tools and hand splinting change what a person can do on a bad day, and they are learned rather than intuited.

The question we are asked most is whether exercise is safe during a flare. The answer is that the type changes rather than stopping: during a flare the programme moves to gentle range-of-movement work and joint protection, and returns to loading as the flare settles.

Stopping entirely during flares and restarting from zero afterwards is the pattern that costs the most function over years.

The small joints of the hands and feet are affected earliest and most often, and hand function determines a very large part of independence — dressing, eating, writing, working.

Occupational therapy addresses this directly: grip and pinch strength, joint protection technique, splinting where a joint needs support, and adaptation of the tasks that matter most to the person. Grip strength is measured rather than described.

During an active flare, intensity comes down but movement does not stop. Gentle range-of-movement work maintains what would otherwise be lost, and joints held still during flares stiffen in ways that do not fully reverse.

Between flares the programme is genuinely progressive. Strength training in rheumatoid arthritis was avoided for years on the assumption that it damaged joints; the evidence does not support that, and inactivity carries the larger cost.

Fatigue in rheumatoid arthritis is a feature of the disease rather than a consequence of poor effort, and it is often the symptom people find hardest to explain to others. It responds to graded activity, sleep work and pacing — not to pushing through.

It is asked about specifically at assessment, because people frequently do not raise it, assuming it is not a medical matter.

Joint protection means changing how load is applied — using larger joints for heavier tasks, distributing load across the hand, adapting tools and handles — rather than avoiding use.

The distinction matters. Protected joints stay usable; avoided joints lose the muscle around them, and the weakness that follows leaves them less protected than before.
