About this study
The purpose of the present study was to examine the effects of the Emotional Freedom Technique on pain and anxiety in the postoperative period of patients who underwent total knee arthroplasty.
Research Hypotheses H1: Emotional freedom technique reduces postoperative pain level in patients undergoing total knee arthroplasty.
H2: Emotional freedom technique reduces postoperative anxiety level in patients undergoing total knee arthroplasty.
Read the detailed description
One day before the surgery the patients in both groups will interviewed and the Patient Descriptive Data Form, Visual Analog Scale (VAS) Pain, and State Anxiety Inventory (SAI) will applied. Then, information will given to the experimental group about EFT and the patients' questions will answered. On the first postoperative day between 18.00 and 20.00 the patients in both groups will interviewed to collect the pretest data and VAS Pain, SAI, and Subjective Unit of Experience Scale (SUE) will applied. Then, the EFT steps will explained and demonstrated to the experimental group and a session of EFT will applied. After the EFT, the SUE Scale will re-evaluated without any break. On the second postoperative day between 18.00 and 20.00 the patients in both groups will interviewed again, and the SUE Scale will evaluated. Then, a session of the EFT will applied to the experimental group. After the EFT, VAS Pain, SAI, and SUE will re-applied without any break for post-test data. In the control group VAS Pain, SAI, and SUE will re-applied for post-test data on the second postoperative day between 18.00 and 20.00.
