- Abstract
- Background: In recent years, there has been an accrued interest in virtual reality (VR) and its potential role in reducing fatigue and depressive symptoms in HD patients. It is important to review the current knowledge on this subject. Objectives: The first objective was to confirm or infirm the hypothesis stating that VR can help reduce fatigue and depressive symptoms in patients on chronic HD. The second objective was to highlight the modalities previously used that could be responsible for these results. Methods: This systematic review was conducted based on the 2020 PRISMA guidelines. We established an equation based on the PICOS criteria. Four databases were used to identify all articles. Results: Out of 203 studies, eight were selected. The majority of the studies showed either a significant reduction of fatigue or of depressive symptoms after a VR intervention. The remaining studies showed the same tendency; however, the results were not significant. The modalities from all these studies included type-content of VR used, the frequency and duration of the VR sessions. Conclusion: We were able to confirm the hypothesis stating that VR helps to reduce fatigue and depressive symptoms. To our knowledge, this is the first review that tries to present the modalities of VR that potentially helped to improve those symptoms in HD patients. More research is needed to fully develop the knowledge surrounding this problematic.
