Exploring extended reality as a therapy for patients with facial paralysis: A scoping review

Objectives: In this study, we explore the use of extended reality (XR) therapy, which includes augmented (AR), virtual (VR), and mixed reality (MR), in patients experiencing symptoms of facial paralysis. Data sources: Pubmed, Scopus, Embase. Methods: A scoping review across PubMed, Scopus, Embase was performed following PRISMA-ScR systematic review guidelines with the use of Covidence. Results: 160 articles were identified and 7 articles, spanning from 2015 to 2023, ultimately met the criteria for this review. The articles reviewed highlight various XR applications and grading systems designed to enhance facial muscle strength, symmetry, and emotional well-being in Bell's palsy patients. Notable programs include FaraPy, FACE2FACE®App, eFace App, Canfeld, RealSense, GY MEDIC, and FaceRehab. These programs exhibit significant potential as effective rehabilitation and assessment tools in facial paralysis patients. Conclusion: The use of extended reality (XR) technologies, along with 3D and 4D imaging, represents a major advancement in the field of facial paralysis therapy. These innovations offer exciting possibilities for enhancing patient care and optimizing outcomes for patients experiencing facial paralysis and muscle deficits. As these technologies start to be integrated into clinical contexts, further research and validation is required to ensure their efficacy and utilization.
