First author’s name VR components Data gathering method Study outcome
Sridhar, et al. [19] Hardware: Smartphone, VR headset, headphones
Software: 3D environment (dream beach, Iceland, dolphins)
Pre-procedural anxiety using a modified Amsterdam Preoperative Anxiety and Information Scale (APAIS) and a Visual Analogue Scale (VAS) for anxiety. The semi-structured interviews to assess each participant’s experience with the VR after the procedure VR was an effective method to reduce anxiety during and after surgery.
Wong, et al. [20] Hardware: VR google headset
Software: VR blossoming tree, ocean waves, and crackling campfire accompanied by meditative auditory guidance specific to pregnancy and laboring women scenario
Visual Analog Scale (VAS), pre intervention survey, Patient Reported Outcomes Measurement Information System (PROMIS) global health survey, childbirth
self-efficacy index (CSEI)
VR was an effective tool for reducing labor pain.
Mosso, et al. [21] Hardware: VR HMD, controller joystick, laptop,
Software: virtual scenarios (Enchanted Forest, Cliff, and Castle)
Visual Analog Scale (VAS) The use of VR in cesarean reduced the pain and anxiety of childbirth and was a powerful and safe tool.
