Current status and clinical perspectives of extended reality for myoelectric prostheses: review

Abstract

Training with “Extended Reality” or X-Reality (XR) systems can undoubtedly enhance the control of the myoelectric prostheses. However, there is no consensus on which factors improve the efficiency of skill transfer from virtual training to actual prosthesis abilities. This review examines the current status and clinical applications of XR in the field of myoelectric prosthesis training and analyses possible influences on skill migration. We have conducted a thorough search on databases in the field of prostheses using keywords such as extended reality, virtual reality and serious gaming. Our scoping review encompassed relevant applications, control methods, performance evaluation and assessment metrics. Our findings indicate that the implementation of XR technology for myoelectric rehabilitative training on prostheses provides considerable benefits. Additionally, there are numerous standardised methods available for evaluating training effectiveness. Recently, there has been a surge in the number of XR-based training tools for myoelectric prostheses, with an emphasis on user engagement and virtual training evaluation. Insufficient attention has been paid to significant limitations in the behaviour, functionality, and usage patterns of XR and myoelectric prostheses, potentially obstructing the transfer of skills and prospects for clinical application. Improvements are recommended in four critical areas: activities of daily living, training strategies, feedback, and the alignment of the virtual environment with the physical devices.

“…Such advancements have led to increased satisfaction rates, significantly improving psychosocial and social adaptation over passive or mechanically controlled prostheses [1]. Myoelectric prostheses are advanced artificial limbs that use electrical signals from a person's own muscles to control the movements of the prosthetic device [2]. The principle of measuring mulcle response or electrical activity in response to a nerve's stimulation of the muscle is called electromyography (EMG) [3] and electrodes are used to interface the body and the acquisition signal system.…”
