Patients with rheumatoid arthritis (RA) tend to be more overweight, take less physical exercise, exhibit decreased cardiorespiratory fitness and demonstrate reduced muscle strength compared with age- and sex-matched controls. Impaired cognitive function in RA is an important associated factor, although it has been less well-recognized. The aim of this study was to investigate the effects of a specifically designed exercise programme on body composition, aerobic capacity, muscle strength and cognition in RA.
Sixty-six patients with RA were randomized to a specifically designed, personalized exercise programme or standard care. Assessments included body composition, fitness, grip strength and cognitive testing, in addition to disease related measures.
Significant improvements in C-reactive protein (p = 0.025), fatigue scores (p = 0.047) and truncal fat (p = 0.004) were observed in the exercise group compared with controls. Median waist circumference was significantly reduced (94.0 to 91.4 cm, p < 0.0001). Improvements were also seen in aerobic capacity (23.2 to 27.6 ml/kg/min, p = 0.002) and in median right (12.0 to 13.0 kg, p = 0.025) and left grip strength (8.0 to 10 kg, p = 0.005). Cognitive function improved in the exercise group, with median Montreal Cognitive Assessment score 25.5 at 0 months compared to 28.0 at 3 months (p = 0.001).
This study demonstrates that exercise has a significant and positive impact on cognitive function in RA. Furthermore, physical activity is safe and effective in chronic inflammatory joint disease and is recommended as a vital component in the holistic management of these patients.
• A dedicated physical exercise programme is feasible and safe in patients with rheumatoid arthritis (RA).
• Physical exercise helps reduce fatigue scores and improves cardiovascular fitness in stable RA patients.
• Physical exercise has a positive impact on cognition in patients with RA.
• A structured exercise programme should be an integral part of chronic disease management protocols for patients with RA.
