Introduction: Rheumatoid arthritis (RA) is a chronic and progressive inflammatory process resulting in the destruction of articular and periarticular tissues and leading to the development of functional impairment, permanent deformities and disability. RA affects approximately 1% of the global population and is more common in women than men. Aim: To assess the effects of physical therapy in RA patients. Material and Methods: The study assessed 21 patients with stage III/IV RA. They were managed with physical therapy, including thermotherapy, electrotherapy, laser therapy, magnetic field therapy and light therapy. The data collected in the study were statistically analysed. Results: After treatment, all study patients showed pain reduction, improved well-being, reduced duration of morning joint stiffness, improved ranges of motion in the joints and a better quality of life. Conclusions: 1. Rheumatoid arthritis is a difficult clinical and social problem. 2. The physical therapy used in the study reduced the pain experienced by the patients and the duration of morning joint stiffness and improved the ranges of motion and quality of life. 3. Physical therapy and rehabilitation constitute the main method of treatment of this disorder.
