The goal of this study is to determine the effect of murottal and classical music on postoperative pain intensity and interleukin 6 levels in patients undergoing lower extremity orthopedic surgery with spinal anesthesia. This study also aims to evaluate whether these therapies can help reduce pain and influence the body's inflammatory response. Main questions to be answered: Can murottal or classical music reduce postoperative pain intensity in patients? Can the use of murottal or classical music lower the levels of interleukin 6, an inflammatory marker, in patients after lower extremity orthopedic surgery? Participants will: Listen to murottal or classical music during their lower extremity orthopedic surgery with spinal anesthesia. Measure pain intensity and interleukin 6 levels before and after the intervention to assess the effect of the therapy. Undergo routine checkups to ensure the safety and success of the therapy. This study aims to provide a deeper understanding of the use of non-pharmacological therapies such as murottal and classical music in managing pain and the inflammatory response in patients after orthopedic surgery.
