The Mayo Clinic defines “Arthritis” as inflammation of one or more joints, whose main symptoms are joint pain and stiffness. The two most common forms of arthritis are osteoarthritis and rheumatoid arthritis. Osteoarthritis (OA) is typically caused by wear and tear, and is often termed “degenerative change.” Rheumatoid arthritis (RA) is an autoimmune disorder.
Nearly all of us will have OA as we age and wear down our joints. That does not mean, however, that we must have pain. There are plenty of folks who have significant evidence of arthritis but zero to minimal discomfort. If we can avoid aggravating our arthritic joints, (i.e. minimize inflammation), we can often limit our misery.
The goal of arthritis treatment is primarily to reduce symptoms of pain, inflammation, and swelling. Physical therapists accomplish this in various ways, including manual (hands-on) techniques, exercise (painfree gentle movement, often in gravity-reduced or eliminated situations like on a stationary bike or in water), and modalities (ice, heat, electrical stimulation, etc.). PTs also educate patients re: prevention and management of symptoms, joint protection (with splints, braces, etc.), and use of assistive devices (crutches, walkers, canes). Exercise consists of range-of-motion exercise to maintain joint mobility and strengthening exercises to improve joint stability.
Each patient may respond differently, so the key is to find out what works best for each individual and go from there.
