The Effect of Progressive Relaxation Exercises on Postoperative Pain

The indicators of patient recovery in the postoperative period include sleep, physical functionality, mental health, cognitive functionality, pain, and psychosocial functionality.

This thesis aims to investigate the effects of progressive relaxation exercises on postoperative pain intensity, sleep quality, and recovery in patients undergoing total knee arthroplasty.This study, designed as a randomized controlled experimental study, will be conducted between September 1, 2023, and August 1, 2024, at ÇAYCUMA State Hospital in ZONGULDAK province, Turkey, among patients undergoing total knee arthroplasty. A total of 96 patients will be recruited based on the sample size calculated using G-power analysis. Through block randomization, 48 patients will be assigned to the intervention group and 48 patients to the control group. Data will be collected using the Numeric Rating Scale for pain, the Richard-Campbell Sleep Scale, a sleep tracker smart wristband to measure sleep quality and duration, the Postoperative Recovery Index, and a Patient Information Form.

Introduction: Knee osteoarthritis is observed in approximately 6% of adult individuals. Knee osteoarthritis, which causes pain in individuals, often results in the impairment of their daily lives. Total knee arthroplasty surgery is considered as the final method in the treatment process of knee osteoarthritis. The indicators of patient recovery in the postoperative period include sleep, physical functionality, mental health, cognitive functionality, pain, and psychosocial functionality.

Objective: This thesis aims to investigate the effects of progressive relaxation exercises on postoperative pain intensity, sleep quality, and recovery in patients undergoing total knee arthroplasty.

Method: This study, designed as a randomized controlled experimental study, will be conducted between September 1, 2023, and August 1, 2024, at ÇAYCUMA State Hospital in ZONGULDAK province, Turkey, among patients undergoing total knee arthroplasty. A total of 96 patients will be recruited based on the sample size calculated using G-power analysis. Through block randomization, 48 patients will be assigned to the intervention group and 48 patients to the control group. Data will be collected using the Numeric Rating Scale for pain, the Richard-Campbell Sleep Scale, a sleep tracker smart wristband to measure sleep quality and duration, the Postoperative Recovery Index, and a Patient Information Form. The progressive relaxation exercises Compact disc 8 (CD) prepared by the Turkish Psychologists Association will be used for the patients' progressive relaxation exercise training. The data will be analyzed using the Statistical Package for the Social Sciences (SPSS) program. The data will be presented as numbers and percentages, means and standard deviations, and their distribution will be assessed to determine whether parametric or non-parametric tests should be employed for analysis. The data will be evaluated with a significance level of p\<0.05 and a confidence interval of 95%.
