Does virtual reality reduce pain in pediatric patients? A systematic review.

Virtual Reality (VR) as a tool for pain reduction is the research topic of several clinical trial for Randomized Controlled Trials despite its wide use in the daily clinical practice for non- pharmacological reduction of pain in some countries. At present, there are no published reviews of VR-efficacy of pain reduction in pediatric patients. That is why we made a systematic review of the efficacy of VR as a tool for pain reduction in children and adolescents. Electronic databases and gray literature published between 2014 and 2019 were analyzed. A total of 9 studies were eligible according to the established inclusion criteria. Results show that virtual reality is a valid tool for non-pharmacological pain reduction and that this approach is to be preferred to the standard reduction techniques currently in use. However, more studies using standardized experimental methodologies are needed to provide more systematic comparison and quantitative synthesis.
