Self-reported activity misaligns with accelerometry in RA; leaves open whether objective measures should supplant self-reports for fitness assessment.
Does subjective physical activity assessment agree with objective accelerometry and correlate similarly with cardiorespiratory fitness in patients with rheumatoid arthritis?
In patients with rheumatoid arthritis, self-reported physical activity underestimates sedentary time and overestimates moderate activity compared to accelerometry, highlighting the need for objective measurements when assessing cardiorespiratory fitness.
