Background: Inadequate pain management and sleep disturbances o patients undergoing gynecological surgery are associated with delayed recovery time. This study aimed to assess the eect o Jacobson’s Progressive Relaxation Technique (JPRT) on postoperative pain, activity tolerance, and sleeping quality in patients undergoing gynecological surgery. Materials and Methods: A randomized controlled clinical trial conducted at Obstetrics and Gynecology Department/Damanhour educational institute, Elbehira, Egypt. The study sample involved 116 patients undergoing gynecological surgery who were equally distributed between intervention and control groups. Data collected rom April to September 2019. Four tools were used or data collection: Demographic data interview schedule, pain analog scale, activity tolerance questionnaire, and the Groningen sleeping quality scale. For the intervention group, the women were asked to perorm JPRT or 30 min on the second and third postoperative day, three times a day. SPSS 23.0 is used to analyze data using Chi‑square, Fisher’s exact, independent t‑test, and Analysis o Covariance (ANCOVA). A signicance level considered at p < 0.05. Results: The study results showed that JPRT signicantly improves pain, sleep quality, and activity tolerance mean scores among the intervention group compared to the control group (F1 = 119.13, p < 0.001), (F1 = 361.49, p < 0.001), and (F1 = 157.49, p < 0.001), respectively. ANCOVA results showed that 33% o the decreased pain score, 12% o decreased sleeping quality score, and 26% o improved activity tolerance score are due to JPRT. Conclusion: JPRT should be oered as a part o standard postoperative nursing care or patients undergoing gynecological surgery to control pain and improve sleeping quality and activity tolerance.
