Development, Feasibility, and Effectiveness of Smartphone Application for Hand Therapy for Patients With Rheumatoid Arthritis: Mix Method Study

The long-term beneficial effects of strengthening and stretching for rheumatoid arthritis (RA) for hand programs (SARAH) on functions have been shown in recent studies. Also, recently a usable web-based hand exercise program developed for patients with RA in UK. 1- The aim of our study is to develop and design a smartphone application for structured hand exercise program for patients with RA and to test its usability. 2- Evaluate the feasibility and effectiveness of smartphone app hand exercise app. In our study, a qualitative iterative design approach that includes focus groups of experts/patients was used. The mobile application was designed in 3 phases: PHASE 1: we conducted focus group meetings to compromise the content, feature and design of app in the first phase (Prototype version of smartphone software for RA hand training program/Mar-Hand-Therapy app). Focus Group were consisted two physiotherapist (PT), three hand therapists (HT) working in the field in different rheumatology or hand rehabilitation clinics, two software-computer engineers, 3 patients with RA who had previously participated hand therapy. All focus group members (n=10) and 6 patients used the app for one week. All users filled the usability questionnaire, made the comments and advises. The revised version was tested again for one week. The last revised version completed after two weeks tested. 40 patients diagnosed with rheumatoid arthritis will be included to the study. Participants randomized to digital intervention and waiting list control. After the 6-week digital intervention qualitative interviews have done with 6-15 patients from intervention group to assess the feasibility of digital intervention. The primary outcomes are hand pain and function and exercise adherence.
