Abstract

© 2017 Elsevier España, S.L.U. Objective: This study aims to show evidence of the Empowerment Session's effectiveness through measurements of surgery related emotional stress before and after this session. Method: The study was performed on 41 patients with knee arthroplasty surgery prescription by measuring the evolution of their emotional stress generated by surgery expectative, during the empowerment session. Two sets of measurements per patient were performed, before and after the empowerment session. Each set consisted of recording an electrocardiogram for 10 min while the patients were seated and then applying two standard psychometric tests: State-Trait Anxiety Inventory test and Visual Analog Stress test. Differences in emotional stress were analyzed using psychometric tests and heart rate variability (HRV) analysis as stress biomarkers. Results: Psychometric stress measurement shows a 17.8% reduction in stress according to the total stress scale value, and a 41.9% reduction in stress between test results before and after the session. Mean heart rate values increased by 7.4% with respect to the initial values, very low frequency power and total power also change in value suggesting more sympathetic and less parasympathetic activity. Conclusions: Both psychological and physiological measurements suggest the effectiveness of the empowerment session due to a significant increase in the wellness state of patients. Additionally, the correlation between psychometric tests and HRV indices demonstrates that both emotional stress indicators could be used as feedback on the empowerment sessions or as a reference to enhance surgical outcomes.
