Effect of Stress Ball Intervention on Psychophysiological Responses During Hernia Surgery: A Randomized Controlled Trial

Participants' demographic information will be collected interview using the Patient Information Form. Approximately 30 minutes before surgery, patients' systolic and diastolic blood pressure, heart rate, respiratory rate, and oxygen saturation will be measured and recorded. Pain severity will also be assessed using the VAS, and anxiety levels will be assessed using the VAS-A and Spielberger Trait Anxiety Scale. Intraoperative Period: All patients will be placed in the supine position on the operating room table. Patients in the intervention group will continue to use the stress ball for 15 minutes during the surgery, as per randomization. All patients will undergo a repeat 15-minute postoperative assessment of vital signs (systolic and diastolic blood pressure, heart rate, respiratory rate, oxygen saturation), pain with a VAS, and anxiety levels with a VAS-A. After the patients are taken to the clinic after the surgery, the same physiological measurements will repeated 10 mnt later
