On March 11th/2020, the World Health Organization (WHO) declared Coronavirus Disease 2019 (COVID-19), a disease caused by the new coronavirus (severe acute respiratory syndrome coronavirus 2-SARS-COV-2), a pandemic. 1 In this global crisis, physical therapy all over the world, is being challenged to maintain its professional clinical activities in primary and secondary care in private clinics and public health systems. 2,3 Part of the challenge is to continue to provide necessary clinical care in a safe manner, for physical therapists, patients, and the community, by following the general recommendations of the WHO. 1 Social distancing and the interruption of physical therapy activities can have a tremendous negative impact on the health of thousands of patients. Digital physical therapy offers the possibility to continue providing some physical therapy services to patients, but regulations and implementation barriers are extremely heterogeneous around the world.

Objective We aimed to perform a standardized review of available mobile health (mHealth) applications (apps) for systemic lupus erythematosus (SLE) and to conduct a systematic review of the literature on mHealth technologies in SLE. Methods Google Play and AppStore in the United States of America were queried and the quality of eligible mHealth apps was assessed using the Mobile App Rating Scale (MARS). Web of Science, EMBASE, Medline, and Cochrane databases were systematically searched from inception through June 2019. Results Of 324 mHealth apps found, 20 were eligible for inclusion; 10 focused on education, 7 offered tools to track patient-reported symptoms, 5 included interactive online communities, and 1 enabled emoji sharing. The reviewed apps scored poorly on the MARS quality scale with a mean score 2.3 (0.6) out of 5. Of 1147 studies identified in the literature review, 21 were eligible for inclusion; 11 studies (52.4%) focused on the development and use of mHealth for providing patient information, while only 2 (9.5%) were randomized trials of mHealth interventions. Conclusions Although there is growing interest in the development of mHealth technologies to support SLE patients, currently available tools are of poor quality and limited functionality, and the literature examining this area is sparse.
