The Efficacy and Safety of Utilizing Mobile Phone–Based Programs and Motion-Capture Devices for Telerehabilitation After Arthroscopic Repair of Rotator Cuff Tear: Study Protocol for a Randomized Controlled Trial

Abstract

Background: Rotator cuff tear is one of the most common diseases in orthopedics, which seriously affects the quality of patients’ lives. And the arthroscopic repair of rotator cuff has recently become more and more popular. Systematic rehabilitation makes great significance for improving the prognosis of postoperative patients. Yet, the traditional outpatient rehabilitation is hard to popularize in developing countries like China due to the limitation of traffic and geography. Given this, we plan to develop a telerehabilitation system to facilitate doctors' remote guidance on patients' rehabilitation.Methods/design: Our study is a single-center, prospective randomized controlled trial. 124 patients who underwent arthroscopic rotator cuff repair will be recruited for the study. They will be randomly divided into 2 groups (62 cases in each group) based on the stratification factors of the operator, operation and preoperative diagnosis. The patients in the control group will get clinic and booklet based rehabilitation treatment after operation. However, patients in the experimental group will receive mobile phone and motion-capture device based programs for telerehabilitation after surgery. The primary outcome will be measured by the American Shoulder and Elbow Surgeons (ASES). Secondary outcomes include the Range of motion (ROM), Visual Analogue Scales (VAS), EuroQol-5 Dimension health questionnaire (EQ-5D), University of California at Los Angeles（UCLA）and the retear rate.Discussion: We hypothesize that patients who utilized mobile phone and motion-capture device based telerehabilitation will benefit more in the range of motion and shoulder function than those who received outpatient and manual based rehabilitation. If the hypothesize was confirmed, we could facilitate telerehabilitation for doctors and overcome the geographical and traffic limitations of traditional clinical based rehabilitation.Trial registration: ChiCTR.org.cn, ChiCTR2000030150, Registered on 24 February 2020
