OBJECTIVES: To compare the effectiveness of longstanding (> 52 weeks), supervised exercise therapy with usual care in adults with rheumatoid arthritis (RA) and severe functional limitations. METHODS: Participants were randomised 1:1 to the intervention (individualised goal-setting, active exercises, education and self-management regarding physical activity) or usual care. Primary endpoint was the change in the Patient-Specific Complaints activity ranked 1 (PSC1, 0 to 10) at 52 weeks. Secondary endpoints included the PSC activities ranked 2 and 3 (PSC2, PSC3), Health Assessment Questionnaire-Disability Index (HAQ-DI), Rheumatoid Arthritis Quality of Life Questionnaire (RAQoL), 6-minute walk test (6MWT), Patient Reported Outcome Measurement Information System Physical Function-10 (PROMIS PF-10) and the Short Form-36 Physical and Mental Component Summary Scales (SF-36 PCS and MCS). (Serious) Adverse events (AEs) were recorded. Measurements were done by blinded assessors. Analyses at 52 weeks were based on the intention-to-treat principle. RESULTS: In total, 217 people (90% female, age 58.8 (SD 12.9) years) were randomised (n = 104 intervention, n = 98 usual care available for analyses). At 52 weeks, the improvement of the PSC1 was significantly larger in the intervention group (mean difference (95% CI) -1.7 (-2.4 to -1.0)). Except for the SF-36 MCS, all secondary outcomes showed significantly greater improvements favouring the intervention (PSC2 -1.8 (-2.4 to -1.1), PSC3 -1.7 (-2.4 to -1.0), PROMIS PF-10 +3.09 (1.80 to 4.38), HAQ-DI -0.17 (-0.29 to -0.06), RAQoL -2.03 (-3.39 to -0.69), SF-36 PCS +3.83 (1.49 to 6.17) and 6MWT +56 (38 to 75) m). One mild, transient AE occurred in the intervention group. CONCLUSION: Longstanding, supervised exercise therapy was more effective than usual care in people with RA and severe functional limitations.
