Is Physical Exercise Beneficial for People with Primary Sjögren’s Syndrome? Findings from a Systematic Review

Abstract

Background: The aim of the study was to identify and critically evaluate the best available evidence on the impact of physical exercise on patients with primary Sjögren’s syndrome. Methods: Studies were searched in four electronic databases (PubMed, Web of Science, Scopus, and SportDiscus) from their inception up to September 2024. The methodological quality of the included studies was assessed using the 10-point Physiotherapy Evidence Database (PEDro) scale and the Methodological Index for Non-Randomized Studies (MINORS). Results: A total of four randomized controlled trials and one comparative study were analyzed. The training programs evaluated varied in duration, ranging from 12 to 28 weeks. Exercise was found to have a positive intra-group impact on fatigue, quality of life, and functional capacity. However, exercise does not demonstrate superior effects compared to standard treatment for improving quality of life and disease impact. Conclusions: It is essential to increase the number of studies involving individuals with primary Sjögren’s syndrome across various exercise conditions to more comprehensively evaluate the potential benefits.
