Ecological momentary assessment of daily patient-reported outcomes and actigraphy-measured physical activity and sleep in patients with rheumatoid arthritis and spondyloarthritis: a study protocol.

ABSTRACT:

Background

Rheumatoid arthritis (RA) and spondyloarthritis (SpA) are chronic inflammatory rheumatic diseases characterised by pain, fatigue, mood disturbances, sleep problems and reduced quality of life. These symptoms are highly variable both between individuals and within individuals across days, reflecting the fluctuating nature of disease activity and daily functioning. Although physical activity is known to alleviate many of these symptoms, individuals with RA and SpA often encounter barriers that limit regular engagement. Capturing the dynamic interplay between symptoms and physical activity therefore requires methods that account for day-to-day and moment-to-moment variability. Ecological momentary assessment (EMA), especially when combined with actigraphy, enables real-time
