Iyengar Yoga for Young Adults with Rheumatoid Arthritis: Results From a Mixed-Methods Pilot Study

Context. Rheumatoid arthritis (RA) is a chronic disease that often impacts patient’s quality of life. For young people with RA, there is a need for rehabilitative approaches that have been shown to be safe and to lead to improved functioning. Objectives. This pilot study investigated the feasibility of a single-arm, groupadministered, six-week, biweekly Iyengar yoga (IY) program for eight young adults with RA. Methods. IY is known for its use of props, therapeutic sequences designed for patient populations, emphasis on alignment, and a rigorous teacher training. Treatment outcomes were evaluated using a mixed-methods approach that combined quantitative results from standardized questionnaires and qualitative interviews with participants. Results. Initial attrition was 37% (n ¼ 3) after the first week because of scheduling conflicts and a prior non-RA related injury. However, the remaining participants (n ¼ 5) completed between 75% and 100% of treatment sessions (mean ¼ 95%). No adverse events were reported. The quantitative results indicated significant improvements in pain, pain disability, depression, mental health, vitality, and self-efficacy. Interviews demonstrated improvement in RA symptoms and functioning but uncertainty about whether the intervention affected pain. Conclusion. These preliminary findings indicate that IY is a feasible complementary approach for young people with RA, although larger clinical
