Published: July 20, 2022

Virtual reality (VR) and augmented (AR) are engaging interfaces that can be of benefit for rehabilitation therapy. However, they still not widely used, the use surface electromyography (sEMG) signals is established them. Our goal to explore whether there a standardized protocol towards therapeutic applications since many methodological reviews focus on sEMG control/feedback. A systematic literature review using PRISMA (preferred reporting items meta-analyses) methodology conducted. Boolean search in databases was performed applying inclusion/exclusion criteria; articles older than 5 years repeated were excluded. total 393 selected screening, which 66.15% excluded, 131 records eligible, 69.46% neither VR/AR nor control; 40 remained. Categories are, application: neurological motor (70%), prosthesis training (30%); processing algorithm: artificial intelligence (40%), direct control (20%); hardware: Myo Armband (22.5%), Delsys (10%), proprietary (17.5%); interface: scene model (25%), videogame (47.5%), first-person (20%). Finally, focused neurorehabilitation after stroke/amputation; however, no consensus regarding signal or classification criteria.
