Seventeen databases were searched for randomized controlled trials (RCTs) assessing yoga's effectiveness in treating RA outcomes (disease activity score, pain, and function).

Yoga interventions, in addition to standard medical treatment, improved disease activity scores (standardized mean difference [SMD] \u22120.46, 95% confidence interval [CI] \u22120.73 to \u22120.18) and function (SMD \u22120.42, 95% CI \u22120.78 to \u22120.07) but did not effectively reduce pain (SMD \u22121.06, 95% CI \u22122.62 to 0.50) compared to standard medical treatment alone. All five RCTs found yoga's beneficial effects on one or more outcomes. All yoga interventions included center\u2010based (supervised, group) sessions, and two included additional home\u2010based (unsupervised, individual) sessions. All interventions incorporated 20 yogic poses (6 standing, 5 supine, 5 prone, and 4 seated), 7 breathing practices, and 4 meditation and relaxation practices. Two interventions offered RA\u2010specific yogic pose modifications. Center\u2010based sessions were delivered at least once weekly for 8 weeks\u2019 median duration and around 68 minutes per session. Home\u2010based yoga was recommended thrice weekly for a 10\u2010week mean duration and 40 minutes per session.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Yoga might be useful in addition to standard medical treatment for RA.
