e-Natureza Blue Care: Nature-based Virtual Reality and Pain Perception

"Participants in this group will receive standard pain management care plus one session of immersive virtual reality (VR) using Oculus Go headsets. The session consists of viewing a nature-themed 360º video (e.g., beach, waterfall, songbirds) for approximately 8 minutes, accompanied by synchronized natural sounds.~The VR experience is designed to promote distraction, relaxation, and emotional engagement with nature to support pain relief and emotional regulation. The equipment is sanitized between uses according to hospital infection control protocols."

"Participants in this group will receive the institution's standard pharmacological pain management, monitored and adjusted by the Pain Control Team using the hospital's electronic medical record system. This may include opioid and non-opioid analgesics according to clinical evaluation.~No complementary interventions will be provided during the study period."
