This VR group will be exposed to a unified 15-minute VR video via phone using a VR device and goggles after receiving routine standard care. A 360˚ video with an immersive audio-visual environment describing pre-operative and post-operative experience on the day of the surgery will be provided, by which they can get accustomed to the environment and procedures associated with the surgery.

Patients within this group will be provided with standard routine care followed by VR exposure to an immersive environment (i.e., natural scenery, urban parks, tropical beaches, forests) with background music using a commercially available application (i.e., Nature Treks) through a head-mounted display (HMD) and headsets

The standard group, in which patients will only receive standard care and be provided with routine descriptions of the pre-operative experience, where a surgeon will explain to them what the pre-operative experience would entail.

The VR group will be exposed to a unified 15-minute VR video via phone using a VR device and goggles after receiving routine standard care. A 360˚ video with an immersive audio-visual environment describing pre-operative and post-operative experience on the day of the surgery will be provided, by which they can get accustomed to the environment and procedures associated with the surgery. Background audio will be provided through headsets, and the video will be directed by a neurosurgeon filmed using a Max 360 action VR camera. In the video, actors, neurosurgeons, and nurses will re-enact a typical day for a mock patient undergoing surgery, plus routine post-operative care, including the post-operative immediate recovery room and rehabilitation care by neurosurgeons, psychologists, and physiotherapists in the ward. Patients are allowed to move around freely so that they can experience all aspects of the virtual space, and are encouraged to ask questions at the end.

The Primary outcome for this trial is the change in the intensity of pre-operative anxiety measured by the State-Trait Anxiety Inventory (STA-I) scale and pain measured by visual Analogue Scale (VAS). These outcomes will be measured pre-operatively on the day before surgery. Measurements will be made again post-operatively - within 24 hours. Pre-operative and post-operative STAI-S and VAS will be compared for data analysis.

The Secondary outcome will be the patients' quality of life and satisfaction measured by Evaluation du Vecu de l'Anesthesie Generale (EVAN-G) questionnaire and postoperative stress measured by Perceived Stress Scale PSS-10 within 24 hours and used for data analysis, since the level of satisfaction and the stress caused by thinking time spent at pain can contribute to an increased perception of pain.
