Effects of Yi Jin Bang Exercise and Usual Exercise Therapy in Adults With Subacromial Pain Syndrome

Each participant in this group will do a home-based Yi Jin Bang exercise program four times a week for ten consecutive weeks, which consists of ten minutes of warm-up, 18 minutes of Yi Jin Bang exercise (ten exercises), and ten minutes of cool-down. To learn how to conduct the home-based exercise session, each participant will be invited to one introductory session before starting the prescribed exercise program. Two experienced Yi Jin Bang instructors will lead the introductory session. Besides, in order to monitor participants' adherence and help them to conduct self-training, we will use the Zoom Meeting application. Zoom can capture and record participants' movements through the webcam. During the introduction sessions, we will teach participants how to use Zoom. Furthermore, we will provide support for adherence to the home exercise sessions through telephone calls or e-mail every two weeks.

Among exercise therapy in the treatment of SAPS, stretching and strengthening protocols are often used . Therefore, participants in this group will do a standardized home-based stretching and strengthening exercise program four times per week for ten weeks, which is set up according to a previous study. This program has been demonstrated that can be effective in reducing pain and improving function in patients with SAPS. For strengthening exercises, elastic bands will be used. To learn how to conduct the self-training program, each participant in this group will also be invited to one introductory session before starting the prescribed exercise training. Two certificated physiotherapists will lead the introductory session. In addition, a video demonstration clip will be given to each participant to provide a home reference, and the Zoom Meeting application will be used to help monitor the exercise.
