Mobile Application for Improving Rehabilitation After Flexor Tendon Repair

Can a mobile application improve adherence, self-efficacy and range of motion after flexor tendon repair? A randomized controlled multicenter trial. Aim Evaluate how the use of a mobile application will affect exercise adherence, range of motion and self-efficacy when compared to standard rehabilitation after flexor tendon repair. Method Multicenter randomized controlled trial. Patients with flexor tendon repair in zone I or II were included and rehabilitated with early active motion and followed 12 weeks post-surgery. Randomization was performed by a computer-generated concealed block to control (n=60) or intervention group (n=60). Both groups received standard rehabilitation according to early active motion. Intervention group also received a smart phone app including; exercise videos, push-notifications for exercise, exercise diary, written information on the surgery, rehabilitation, questions and answers. Evaluation was made at baseline, 2, 6- and 12-weeks after surgery. Primary outcome was physiotherapist rated adherence on the Sport Injury Adherence Scale (SIRAS). Secondary outcome was self-reported adherence, perceived self-efficacy, total Active range of motion (TAM) in the Proximal Interphalangeal (PIP) joint and Distal Interphalangeal (DIP) joint and perceived satisfaction with rehabilitation and information.
