Rheumatoid Arthritis (RA) is a chronic, multisystemic, progressive autoimmune disease characterized by joint destruction in synovial tissue, causing joint swelling, pain and morning stiffness. It is estimated to affect 0.1%-2% of the world's adult population and more women than men. RA limits individuals' work, social, and home lives and functional capacities. Patients commonly experience pain and accompanying sleep problems. Interventions for these problems and symptom management are important. In this regard, this study was planned to examine the effect of distant reiki application on pain, functional status and sleep quality in rheumatoid arthritis patients.
