Introduction: Emergency Medical Workers frequently encounter high-stress situations, such as traffic accidents and sudden deaths, which can negatively affect their mental health. Building psychological resilience through training is essential, and recent methods like virtual reality (VR) gamification have been introduced to improve learning outcomes. Aim: This pilot randomized crossover study aims to compare the stress responses of third-year Paramedicine students during a severe traffic accident scenario using either a live actor simulation or a VR-based platform (XVR simulation). Methods:Ten third-year Paramedicine students were randomly assigned to start with either a live actor simulation or a virtual reality scenario using the XVR program. After completing the first scenario, participants underwent a 7-10 day washout period before switching to the alternate scenario. Physiological stress markers, including salivary cortisol, testosterone, and heart rate variability (HRV), were measured before and after each scenario. Subjective stress was assessed using a ten-point visual analog scale (VAS). Results: No significant differences were observed in cortisol concentration changes (p = 0.576), testosterone levels (p = 0.878), or HRV (p = 0.156) between the virtual reality and live actor simulations. However, students perceived the live actor scenario as more stressful than the virtual reality simulation (p = 0.001). Conclusion: Both virtual reality and live simulations effectively recreate high-stress scenarios, but students reported higher stress during live actor simulations. These results indicate that VR could be a viable and cost-effective alternative for training Paramedicine students. Larger studies are needed to confirm these findings and assess the long-term impact of VR training on stress adaptation.
