A realidade virtual 3D induz desequilíbrio postural em adultos jovens?

Abstract

Background: Previous studies have demonstrated the benefits of virtual reality as an intervention tool guided by specialists. However, little is known about whether virtual reality may pose risks in uncontrolled settings. Objective: To assess the potential risks of postural imbalance in young adults exposed to 3D virtual reality roller coaster simulation. Methods: Seventy-nine healthy participants completed a single 3-minute virtual reality session using a head-mounted display simulating a roller coaster while standing. Postural control was assessed using a force platform measuring frontal and lateral sway, center of pressure sway area, and frontal and lateral imbalance speed. The assessments were conducted with and without the virtual reality. Statistical analysis was performed using paired comparisons. Significance set at 5%. Effect sizes (ES) are reported. Results: Engaging in a 3D virtual reality roller coaster simulation increased the participants imbalance in frontal sway (p = 0.001; ES = 0.919), center of pressure sway area (p = 0.001; ES = 0.849), frontal imbalance speed (p = 0.001; ES = 0.910), and lateral imbalance speed (p = 0.001; ES = 0.663). No significant difference was observed in lateral sway (p = 0.383). Conclusion: The 3D virtual reality roller coaster simulation affected several measures of postural control in young adults. Precautions should be taken when engaging in virtual reality without appropriate specialist supervision.
