Hip and knee replacement surgery is commonly performed in older adults. After surgery, many patients experience pain, limited movement, and sleep problems. These difficulties can make daily activities such as walking or climbing stairs more challenging and may reduce quality of life during recovery.

Relaxation exercises are often used to help reduce pain and improve sleep after surgery. Virtual reality (VR) is a technology that provides a multisensory experience and may help people relax by shifting their attention away from pain and discomfort.

This study is designed to compare two different relaxation approaches used after hip and knee replacement surgery. One group of patients will perform relaxation exercises using virtual reality, while another group will perform traditional relaxation exercises. The study will examine pain levels and sleep quality in both groups.

The results of this study may help to better understand whether virtual reality-based relaxation can be used as an alternative or supportive method for managing pain and sleep problems after joint replacement surgery.
