Brief summary
The goal of this clinical trial is to evaluate whether virtual reality (VR) can effectively reduce perioperative anxiety and pain in patients undergoing lower limb orthopedic surgery under spinal anesthesia. The study focuses on adult patients in a surgical setting, with an emphasis on improving intraoperative experience and postoperative outcomes without relying solely on pharmacological interventions. The main questions it aims to answer are: * Can VR reduce perioperative anxiety and perceived pain levels? * Does the use of VR lower the need for sedative and analgesic medications and improve hemodynamic stability and satisfaction? Researchers will compare a VR intervention group to a standard care group to see if VR leads to reduced anxiety and pain, less medication use, better physiological stability, and improved satisfaction. Participants will: * Undergo orthopedic surgery under spinal anesthesia. * Be randomly assigned to either receive standard perioperative care or standard care plus VR immersion. * In the VR group, engage in calming, immersive virtual environments during the perioperative period.
Detailed description
This randomized controlled clinical trial investigates the effect of immersive virtual reality (VR) on the management of perioperative anxiety and pain in patients undergoing elective lower limb orthopedic surgery under spinal anesthesia. The use of VR as a non-pharmacological adjunct is a novel and promising approach intended to improve the patient's perioperative experience, optimize physiological responses, and potentially reduce the consumption of sedatives and analgesics. Participants in the intervention group will wear a VR headset that delivers immersive, calming visual and auditory content designed to promote relaxation and distraction before, during, and after the surgical procedure. The control group will receive standard care without VR. Both groups will receive spinal anesthesia as part of routine clinical practice. Anxiety and pain will be measured at predefined perioperative time points using validated visual analog scales (VAS) and APAIS scale. Additional data on hemodynamic parameters, sedative and analgesic consumption, intraoperative complications, and postoperative satisfaction (from patients, surgeons, and anesthetists) will be collected to evaluate the overall impact of VR on perioperative care quality and patient outcomes. This study is being conducted at Habib Bourguiba University Hospital, Sfax, Tunisia, over a 12-month period and represents the first clinical evaluation of virtual reality technology in an anesthesia context at this institution. The findings may contribute to the integration of digital tools into routine perioperative care, especially in low-resource settings, by demonstrating their utility in reducing stress, improving comfort, and supporting enhanced recovery after surgery.
Interventions
DEVICEVirtual reality session
Patients included in the intervention group (VR group) participated in a comprehensive virtual reality program designed to reduce perioperative anxiety and pain. Prior to their surgery, they attended an introductory VR session aimed at familiarizing them with the technology and providing a calming, immersive environment to help alleviate preoperative stress. Throughout their surgical journey, these patients continued to receive the usual standard care, which included thorough preoperative consultations with healthcare providers, detailed information about the planned surgical procedure, and the provision of standard postoperative care to support recovery. Additionally, during the surgery itself, patients underwent a VR session delivered via a headset, offering real-time immersive distraction and relaxation to minimize intraoperative anxiety and pain perception.

Intervention model description
Participants will be randomly assigned in parallel to one of two groups: the intervention group receiving virtual reality exposure during the perioperative period, or the control group receiving standard care. Each participant remains in their assigned group throughout the study, and outcomes will be compared between the two groups.
