Digital Osteoarthritis Care

Osteoarthritis (OA) is among the most prevalent and costly diseases, with an estimate of $460 billion in all-cause medical costs. It causes pain and reduced physical function, and with no existing cure, the recommended first-line treatment is information, exercise and weight management if indicated. As the prevalence of OA is expected to increase in the coming years, exploring innovative solutions to maintain economical sustainable treatment in the future becomes a necessity. Telerehabilitation, technology which involves providing treatment through information and communication technology, regardless of the patient's geographical location, has shown its potential within cardiac, pulmonary, neurological and musculoskeletal conditions. Virtual Training (VT) is a generic mobile health application used to deliver digital home exercise programs with text, audio and video support. Through a novel feedback system the therapist is able monitor the patients progress and pain level during exercise. This project aims to investigate, through a randomized controlled trial (RCT), whether the use of the VT-app is as effective as supervised exercise therapy in improving pain, physical function and disease activity in patients with hip and/or knee osteoarthritis. In addition, the investigators want to investigate if the use of the app is more cost effective than supervised exercise therapy, whether the use increases adherence with first line treatment, and whether there are certain characteristics of the patients responding to the intervention.
