Developing a Core Stability Training Program for Patients Following Total Knee Arthroplasty, Informed by Self-efficacy Theory: A Delphi Method Study

Objective: To construct a CST program for patients after TKA. Materials and Methods: Based on the principles of SET and following evidence, this project was constructed using the qualitative method of literature analysis and the Delphi method. The Delphi panel consisted of fifteen experts from the fields of clinical medicine, rehabilitation medicine, and nursing. Results: Fifteen experts were consulted and the consultation response rate was 100%; the authority coefficient for the first round was 0.89, with coefficients of variation ranging from 0.00 to 0.24, and importance ratings ranging from (3.4±0.83) to (5±0); the authority coefficient for the second round was 0.91, with coefficients of variation ranging from 0.00 to 0.23, and importance ratings ranging from (4.0±0.93) to (5 ± 0); Kendall’s harmony coefficients were 0.235 and 0.245, respectively, with statistically significant differences (p < 0.05). The construction of SET-based CST program for post-TKA patients included 4 primary, 10 secondary and 15 tertiary indicators. Conclusion: The construction of SET-based CST program for postoperative TKA patients is scientific and feasible, with universal applicability, and can provide a reference basis for healthcare professionals to develop postoperative rehabilitation training for such patients.
