Effectiveness of longstanding exercise therapy compared with usual care for people with rheumatoid arthritis and severe functional limitations: a randomised controlled trial.

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, 0-10) 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, -1.0)). Except for the SF-36 MCS, all secondary outcomes showed significantly greater improvements favouring the intervention (PSC2 -1.8 (-2.4, -1.1), PSC3 -1.7 (-2.4, -1.0), PROMIS PF-10 +3.09 (1.80, 4.38), HAQ-DI -0.17 (-0.29, -0.06), RAQoL -2.03 (-3.39, -0.69), SF-36 PCS +3.83 (1.49, 6.17) and 6MWT +56 (38, 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.

The Extent and Nature of Functional Limitations According to the Health Assessment Questionnaire Disability Index in Patients with Rheumatoid Arthritis and Severe Functional Disability.

BACKGROUND: For a subgroup of people with rheumatoid arthritis (RA) and severe disability, insight into their limitations is crucial for adequate treatment. AIM: To describe the extent and nature of functional limitations in people with RA and severe disability and to explore the associations of the extent of the functional limitations with patient characteristics, disease characteristics, and outcome measures. METHODS: Baseline data of 215 participants in an RCT on the (cost-)effectiveness of longstanding physiotherapy were used. Functional limitations were assessed with the Health Assessment Questionnaire Disability Index (HAQ-DI). The total HAQ-DI including eight domain scores were calculated. Associations between high HAQ-DI scores (≥2, yes/no) and other variables were examined using the Student's t-test or Chi-squared test where appropriate. RESULTS: The participants (90% women, age 58.8 ± 12.8 years) had a mean HAQ-DI score of 1.7 ± 0.5. The majority (56%) showed a moderate-to-severe disability in all domains. Higher HAQ-DI scores seemed to be associated with advanced age, longer disease duration, unemployment, joint replacements, and outcomes for daily functioning and physical quality of life, but not with measures of disease activity. CONCLUSIONS: Our findings indicate that a comprehensive assessment of all areas of daily activities in this subgroup is necessary in order to provide appropriate (non-)pharmacological care.

Functional limitations of people with rheumatoid arthritis or axial spondyloarthritis and severe functional disability: a cross-sectional descriptive study.

The objective of the study is to describe the nature of functional limitations in activities and participation in people with Rheumatoid Arthritis (RA) or axial SpondyloArthritis (axSpA) with severe functional disability. Baseline data from people with RA (n = 206) or axSpA (n = 155) and severe functional disability participating in an exercise trial were used. Their three most limited activities were derived from the Patient Specific Complaint (PSC) instrument and linked to the International Classification of Functioning and Health (ICF). The frequencies of ICF categories were calculated and compared with Activities and Participation items of the ICF Core Sets for RA (32 second-level categories) and Ankylosing Spondylitis (AS) (24 second-level categories). In total 618 and 465 PSC activities were linked to 909 (72 unique in total; 25 unique second-level) and 759 (57 unique in total; 23 unique second-level) ICF categories in RA and axSpA. Taking into account all three prioritized activities, the five most frequent limited activities concerned the ICF chapter "Mobility", and included "Walking" (RA and axSpA 2 categories), "Changing basic body position" (RA and axSpA 1 category), "Stair climbing"(RA) and "Grasping" (RA),"Lifting" (axSpA) and "Maintaining a standing position" (axSpA). In RA, 21/32 (66%) and in axSpA 14/24 (58%) unique second-level categories identified in the prioritized activities are present in the Comprehensive Core Sets. Most limitations of people with RA or axSpA and severe functional disability were seen in the ICF chapter "Mobility". Most of the identified ICF categories were covered by the corresponding items of the ICF RA and AS Core Sets.

Quality of reporting and nature of harms in clinical trials on supervised exercise in patients with rheumatoid arthritis or axial spondyloarthritis.

To describe the quality of reporting and the nature of reported harms in clinical studies on the effectiveness of supervised exercises in patients with rheumatoid arthritis (RA) or axial spondyloarthritis (axSpA). We performed a systematic review, searching eight databases up to February 2023. Randomized controlled trials (RCTs) evaluating supervised exercises in adults with RA or axSpA were considered eligible. Data on harms were extracted according to the CONSORT Harms 2022 Checklist. Among others, it was recorded if harms were prespecified or non-prespecified. Moreover, the nature of reported harms was listed. Forty RCTs were included for RA and 25 for axSpA, of which 29 (73%) and 13 (52%) reported information on harms. In 13 (33%) RCTs in RA and four (16%) in axSpA, the collection of harms outcomes was described in the methods section. Prespecified outcomes were reported by eight (RA) and two (axSpA) RCTs. Non-specified harms outcomes were reported by six (RA) and four (axSpA) RCTs. Prespecified harms outcomes included measures of pain, disease activity, inflammation, and structural joint changes. The nature of non-prespecified harms outcomes varied largely, with pain being most common. A considerable proportion of trials on supervised exercise in RA or axSpA does not or inadequately report harms outcomes. Pain was the most commonly reported prespecified or non-specified harm. For a considerate interpretation of the balance between benefits and harms of supervised exercise in RA or axSpA, use of the CONSORT Harms 2022 Checklist for the design, conduct and reporting of trials is advocated.

Effectiveness and cost-effectiveness of longstanding exercise therapy versus usual care in patients with axial spondyloarthritis or rheumatoid arthritis and severe limitations: The protocols of two parallel randomized controlled trials.

OBJECTIVES: Research on effectiveness and cost-effectiveness of longstanding exercise therapy in patients with axial SpondyloArthritis (axSpA) or Rheumatoid Arthritis (RA) is scarce, and mainly concerned patients with a relatively favorable health status. We aim to evaluate the effectiveness and cost-effectiveness of longstanding exercise therapy compared to usual care in the subgroup of patients with axSpA or RA and severe limitations in functioning. METHODS: In two separate, parallel randomized controlled trials the effectiveness and cost-effectiveness of longstanding, active exercise therapy (52 weeks) compared with usual care (1:1) will be evaluated. The longstanding, active exercise therapy will focus on improving individual limitations in daily activities and participation and will be given by a trained physical therapist in the vicinity of the participant. For each diagnosis, 215 patients with severe limitations in activities and participation will be included. Assessments are performed at baseline, 12, 26, and 52 weeks. The primary outcome measure of effectiveness is the individual level of functioning (activities and participation), as measured with the Patient-Specific Complaints instrument at 52 weeks. For cost-effectiveness analyses, the EuroQol (EQ-5D-5L) and questionnaires on healthcare use and productivity will be administered. The economic evaluation will be a cost-utility analysis from a societal perspective. After 52 weeks, the patients in the usual care group are offered longstanding, active exercise therapy as well. Follow-up assessments are done at 104, 156, and 208 weeks. CONCLUSION: The results of these studies will provide insights in the effectiveness and cost-effectiveness of longstanding exercise therapy in the subgroup of axSpA and RA patients with severe functional limitations.
