Relationship Between Objectively Assessed Physical Activity and Fatigue in Patients With Rheumatoid Arthritis: Inverse Correlation of Activity and Fatigue

Fatigue is generally associated with low physical activity in patients with various chronic medical conditions. However, such an association has not been reported among patients with rheumatoid arthritis (RA). The objectives of this study were to investigate whether daily activity level is associated with fatigue in patients with RA, and whether pain, disability, coping, and/or cognition are associated with the level of daily activity.
