Effectiveness of an Exercise Program and Education Through a Mobile Application for the Management of Patients With Hand Osteoarthritis and Rheumatoid Arthritis

Strengthening and stretching exercise programs, and recommendations to protect the affected joint have shown to be effective both clinically and economically in conditions such as hand osteoarthritis and hand rheumatoid arthritis. However, their application format is not up to date. In this sense, problems such as the lack of monitoring by the health professional and the lack of patients motivation may cause poor adherence to the treatment protocol, which is one of the main predictors of treatment efficiency. Therefore, an smartphone application has been developed for the rehabilitation of hand osteoarthritis and rheumatoid arthritis to enhance patients adherence and motivation. The smartphone application includes: a) exercise programs and recommendations based on the most up to date scientific evidence adapted to the pathology; and b) enhancers of patient adherence to treatment (patient diaries and behavioral change strategies).The objective is to develop a cost effective digital solution to optimize the health care offered to these pathologies based on up to date scientific evidence in order to improve the functional ability and the quality of life of these patients, and to reduce the number of consultations to primary and specialized care.
