Outcome Measures
Primary Outcomes (2)
Number of Participants Who Complete the VR Intervention (Feasibility)
Feasibility is evaluated by the drop-off/discontinuation rate. The metric for success is a drop-off rate threshold of less than 10%.
Day 1 -Immediately after the intervention (approximately 8 minutes)
Acceptability Assessed by an Adapted Simulator Sickness Questionnaire (SSQ) Score
Participant acceptability and tolerability are evaluated by measuring overall cybersickness. Participants rate four specific symptoms (nausea, dizziness, headache, and blurred vision) adapted from the Simulator Sickness Questionnaire (SSQ) on a visual analogue scale from 0-100. The scores for these four items are averaged to calculate a single overall mean score. The aggregated score ranges from 0 to 100, where a higher score indicates worse cybersickness. An aggregated score of \< 25 is the pre-defined threshold for clinical acceptability.
Immediately post-intervention (approximately 8 minutes from VR intervention start)
Secondary Outcomes (8)
Change in Pre-operative State Anxiety
Baseline (pre-intervention) to immediately post-intervention (approximately 8 minutes).
Change in Surgery-Specific Fear
Baseline (pre-intervention) to immediately post-intervention (approximately 8 minutes).
Change in Calmness Assessed by Visual Analogue Scale (VAS)
Baseline (pre-intervention) to immediately post-intervention (approximately 8 minutes).
Change in Resting Heart Rate
Baseline (pre-intervention) to immediately post-intervention (approximately 8 minutes).
Change in State Anxiety Assessed by the short Brazilian State Trait Anxiety Inventory (STAI-S)
Baseline to immediately post-intervention (approximately 8 minutes).
- +3 more secondary outcomes
Other Outcomes (1)
Patient Sentiment Score Assessed by Word-Level Semantic Projection Analysis (Exploratory)
Post-Operative Day 1 - During post-operative surgical recovery.
Study Arms (3)
VR+meditation
EXPERIMENTALParticipants experience an 8-minute guided breath meditation delivered via a Pico Neo 3 Head-Mounted Display using a customized study version of the Flow application set in an immersive virtual beach environment. Instruction audio is provided in Portuguese.
Nature VR only
ACTIVE COMPARATORParticipants experience the identical 8-minute immersive virtual beach environment using the same hardware and application, but without any guided meditation or audio instruction, serving as a standard environmental VR distraction.
Care as usual
NO INTERVENTIONParticipants receive standard pre-operative surgical care in the holding room environment for an equivalent 8-minute period without VR exposure.
Interventions
An 8-minute guided breath meditation delivered via a Pico Neo 3 Head-Mounted Display using the Flow® application, set in an immersive virtual beach environment with custom Portuguese audio instruction.
An 8-minute immersive virtual beach environment using the Flow® application on a Pico Neo 3 Head-Mounted Display, provided without any guided meditation or audio instruction.

- Possessing sufficient vision and hearing to engage with the VR experience
You may not qualify if:
