Ecological Momentary Assessment and Physical Activity in Patients With Inflammatory Rheumatic Diseases

Chronic inflammatory rheumatic diseases (IRDs), such as rheumatoid arthritis and spondyloarthritis, can cause pain, fatigue, and mobility issues, significantly impacting patients' quality of life. Physical activity is an important part of managing these conditions, as it helps reduce pain, maintain mobility, and prevent complications. However, many patients struggle to stay active due to pain and fatigue. A better understanding of these challenges could lead to improved support and interventions. This study explores a new way to monitor the daily experiences of patients with IRDs using Ecological Momentary Assessment (EMA), a method that collects real-time data through a mobile app. The study will also use actimeters-wearable devices that track physical activity. Over 14 days, participants will answer short surveys on their phones and wear an actimeter to provide insights into how fatigue, pain, mood, and physical activity levels change throughout the day. Before this approach is implemented in a larger study, its practicality and acceptability for patients must be evaluated. This pilot study will assess whether participants find the mobile app and actimeter easy to use, how often surveys are completed, and whether frequent reminders affect participants' willingness to continue. The study will also examine the immediate and delayed effects of different symptoms on physical activity and explore factors that influence participant engagement with the protocol. By identifying potential barriers and solutions, this research will help refine future studies and improve methods for monitoring and supporting individuals with IRDs in staying active while managing symptoms.
