Harnessing Virtual Reality for Pain Management: A Comprehensive Systematic Review and Meta-Analysis

Background: Virtual reality (VR) is marked by both progress and ongoing challenges. Significant advancements have been made in healthcare, where VR is used for therapy, rehabilitation, and medical training. VR holds numerous untapped applications in the medical field, with pain management standing out as a significant yet often overlooked area. Despite its critical importance in disease management and therapy, pain relief remains underemphasized in many healthcare approaches. Objective: To conduct a systematic review and meta-analysis on the effectiveness of VR in pain management. Methods: A Comprehensive literature search was conducted across multiple databases, including PubMed, Cochrane Library, Medline, Embase, and PsycINFO, using Boolean operators and adhering to PRISMA guidelines. The search aimed to identify studies evaluating VR-based interventions for pain management, distraction, and reduction. Studies were included based on predefined inclusion criteria, with a focus on those utilizing standardized pain assessment scales. Data extraction encompassed study characteristics, patient demographics, and reported pain outcomes. Result: Around 20 studies were used to assess the effectiveness of VR as a pain management tool. Of these, 95.2% reported positive outcomes, highlighting VR’s effectiveness in pain distraction. These findings emphasize VR’s potential as an innovative, non-invasive pain relief method. Studies included various pain scales and diverse age groups. VR was found to be beneficial across medical conditions, reducing reliance on medication. Conclusion: VR is emerging as a valuable asset in contemporary pain management. Its ability to provide immersive distraction has the potential to transform pain relief protocols, diminish dependence on pharmacological treatments, and improve the patient care experience.
