Efficacy of home-based physical activity interventions in patients with autoimmune rheumatic diseases: A systematic review and meta-analysis

Abstract

IntroductionPhysical activity (PA) has been receiving increasing interest in recent years as an adjuvant therapy for autoimmune rheumatic disease (ARDs), but there is scarce information about the efficacy of home-based PA for patients with ARDs. ObjectiveTo perform a systematic review and meta-analysis on the efficacy of home-based physical activity (PA) interventions in improving health-related quality of life, functional capacity, pain, and disease activity in patients with ARDs. MethodsSearches were performed in PubMed, Web of Science, Scopus, Cochrane, CINAHL database and Sport Discus. Trials were considered eligible if they included a home-based physical activity intervention. The population included adults with autoimmune rheumatic diseases (e.g., rheumatoid arthritis, systemic lupus erythematosus, idiopathic inflammatory myopathies, systemic sclerosis and ankylosing spondylitis), comparisons included non-physical activity control or centre-based interventions (i.e., interventions performed on a specialized exercise centre) and the outcomes were quality of life, pain, functional capacity, disease activity and inflammation. ResultsHome-based physical activity improved quality of life (p<0.01; g = 0.69; IC95%, 0.61 to 1.07) and functional capacity (p = 0.04; g = - 0.51; IC95%, -0.86; -0.16), and reduced disease activity (p = 0.03; g = - 0.60; IC95%, -1.16; -0.04) and pain (p = 0.01; g = -1.62; IC95%, -2.94 to -0.31) compared to the non-physical activity control condition. Additionally, home-based physical activity interventions were as effective as centre-based interventions for all investigated outcomes. ConclusionHome-based PA is an efficacious strategy to improve disease control and aleviate symptoms in ARD.
