TOPLINE:
Adults whose rheumatoid arthritis caused them severe functional limitations showed significant improvement in measures of function and quality of life following at least 1 year of a personalized, supervised exercise program than those who received usual care.
METHODOLOGY:
- Researchers randomized 217 adults with rheumatoid arthritis and severe functional limitations to an active exercise intervention delivered by a physical therapist (PT) or usual care; the mean age of the participants was approximately 59 years, and approximately 90% were female.
- The intervention consisted of individualized goal setting, active exercises adapted to functional limitations, and education about self-management of physical activity in two sessions per week for the first 12 weeks, followed by once weekly sessions with the option for additional sessions if needed. The primary care PTs in the Netherlands who treated the patients were primarily recruited through a national network of PTs with specific expertise regarding rheumatic diseases.
- In considering each participant’s three most limited activities, the study’s primary outcome at 52 weeks measured the change from the one ranked highest at baseline on the Patient-Specific Complaints Numeric Rating Scale (PSC1 NRS); secondary outcomes included changes in the NRS for participants’ second and third most difficult activities, as well as the Patient Reported Outcome Measurement Information System Physical Function-10, the Health Assessment Questionnaire-Disability Index, the Rheumatoid Arthritis Quality of Life Questionnaire, the 36-Item Short-Form Health Survey (SF-36) Physical and Mental Component Summary Scales (PCS and MCS), and the 6-minute walk test.
TAKEAWAY:
- At 52 weeks, the change in PSC1 NRS was significantly greater in the intervention group than in the usual care group, with a mean difference of −1.7 and a between-group effect size from baseline of 0.7.
- Improvements in secondary outcome measures at 52 weeks also were significantly greater in the intervention group than in the usual care group, with the exception of the SF-36 MCS, which showed no difference between the groups.
- A total of 89 participants in the intervention group and 45 participants in the usual care group responded to questions about muscle soreness and fatigue; 70% and 60%, and 71% and 64%, of each group reported these conditions, respectively.
IN PRACTICE:
“The completion of the trial substantiates the feasibility of recruiting and training primary care [physical therapists] to deliver a complex intervention,” although more research is needed to explore long-term outcomes and cost-effectiveness, the researchers wrote.
SOURCE:
The lead author on the study was Max M.H. Teuwen, MSc, a PhD candidate at Leiden University Medical Center, Leiden, the Netherlands. The study was published online in Annals of the Rheumatic Diseases.
LIMITATIONS:
The participants were not blinded to their group, and blinded assessors became aware of the allocations, which might have impacted measurements; other limitations included lack of data on medication changes and the exclusion of physical activity amount as an outcome measure.
DISCLOSURES:
The study was supported by the Netherlands Organization for Health Research and Development; the Ministry of Health, Welfare and Sport; the Royal Dutch Society for Physical Therapy; and the Dutch Arthritis Society. The researchers had no financial conflicts to disclose.
