Introduction Rheumatoid arthritis (RA) patients often experience significant hand dysfunction. Yijinjing, a traditional Chinese exercise, has been recognized for its benefits to mind–body health. This study aimed to evaluate the efficacy and safety of Yijinjing in improving hand dysfunction among individuals with RA. Methods This research was conducted as a single-center, outcome-blinded, randomized controlled trial. A total of 66 eligible RA participants were randomly assigned in a 1:1 ratio to either the Yijinjing exercise group (YJJG) with sessions conducted three times per week over a 12-week period or the control group (CG), which maintained ordinary activities. Various outcomes were assessed, including the Michigan Hand Outcomes Questionnaire (MHQ), handgrip strength, active range of motion (AROM), RA disease activity, the Health Assessment Questionnaire Disability Index (HAQ-DI), levels of anxiety and depression, and wrist ultrasound, all of which were collected at baseline and the week 12. Results At the end of the 12 weeks, the YJJG demonstrated significant improvements in MHQ scores compared to the CG ( p < 0.05), alongside enhancements in handgrip strength and AROM, specifically in wrist extension, radial deviation, and metacarpophalangeal flexion ( p < 0.05). Wrist ultrasound scores did not exhibit a significant increase in the YJJG, meaning no inflammation aggravation ( p > 0.05). Additionally, morning stiffness duration, Disease Activity Sco...
