Mobile rehabilitation support versus usual care in patients after total hip or knee arthroplasty: study protocol for a randomised controlled trial
Abstract
Abstract Background The global increase in total hip or knee arthroplasty has led to concern about the provision of postoperative rehabilitation. Telerehabilitation may be a strategy to meet the patients’ requirements for rehabilitation after arthroplasty. This study aims to investigate the effectiveness of a telerehabilitation programme delivered via the mobile application WeChat in patients after total hip or knee arthroplasty on the following outcomes: self-efficacy, physical function, pain, depression, anxiety and health-related quality of life. Methods This is a single-centre, single-blinded, parallel-group, superiority randomised controlled trial conducted in Shanghai, China. Eighty-four eligible participants who undergo primary total hip or knee arthroplasty will be recruited preoperatively in a university teaching hospital and randomly assigned to the experimental or control group with their informed consent. Once discharged, the control group (n = 42) will receive the usual care provided by the hospital. The experimental group (n = 42) will receive usual care and a 6-week mobile application rehabilitation programme that consists of physical exercises and techniques for enhancing participants’ self-efficacy for rehabilitation. Baseline assessments will be conducted on the day before hospital discharge, and outcome assessments will be conducted 6 and 10 weeks postoperatively. The primary outcomes are changes in self-efficacy and physical function 6 weeks postoperatively, and the secondary outcomes include pain, depression, anxiety and health-related quality of life. The approach of a generalised estimating equation will be used to analyse the effect of the intervention on outcomes at a significance level of 0.05. Discussion This study is the first of its kind conducted in China to incorporate self-efficacy and learning theories as a framework to guide the development of a mobile application rehabilitation programme after arthroplasty. This study will contribute to the knowledge about the effectiveness of mobile application-based rehabilitation among patients after total hip or knee arthroplasty. If the findings are positive, they will support the implementation of mobile application-based rehabilitation in practice, which may potentially increase the accessibility of rehabilitation services as well as patient adherence to rehabilitation.
