Abstract: Objective: To develop an early postoperative functional exercise program for humeral tumor survivors with Reverse Total Shoulder Arthroplasty (RTSA), and to provide a reference for early postoperative functional exercise. Methods: Based on the evidence-based practice principles, the research team initially formulated an early functional exercise program for RTSA. Two rounds of Delphi expert consultation were conducted from March 10, 2020 to March 30, 2020, and adjustments were made according to expert suggestions. Results: In the first round, 17 experts were consulted, and 15 valid questionnaires were collected, with an effective recovery rate of 88.2%. The variation coefficient of each item was between 0.061 and 0.286, and the Kendall harmony coefficient was 0.104 (P<0.05). Fifteen experts were consulted in round two with an effective recovery rate of 100.0%. The variation coefficient of each item was between 0 and 0.128, and the Kendall harmony coefficient was 0.112 (P<0.05). The mean value of importance assignment was 4.67 to 5.00. Finally, 3 first-level items, 9 second-level items, and 22 third-level items were formed. Conclusion: The early postoperative functional exercise program developed in this study is scientifically reliable, highly operable, and has clinical application values.
