Rheumatoid arthritis (RA) and osteoarthritis (OA) (Rheumatoid Arthritis vs Osteoarthritis)  are two of the most prevalent forms of arthritis, affecting millions of individuals worldwide. While they share some similarities, they also have distinct characteristics that set them apart. Understanding the differences between RA and OA is crucial for healthcare professionals, particularly occupational therapy practitioners, as it informs their approach to assessment and intervention for patients with these conditions.
