Abstract

This thesis highlights the current gold-standard surgical procedures for the rehabilitation of mimicry in individuals with facial paralysis and explores the potential application of functional electrical stimulation (FES) as a novel treatment restoring the face mimicry. Closed-loop facial pacing represents an innovative solution for prosthetically assisted movements. In particular, blinking is typically symmetrical, enabling healthy eye blink on one side of the face to serve as a trigger to pace assisted blinks on the contralateral side, in case of unilateral peripheral facial palsy. The goals of this research are developing an eyeblink detection system and advancing the understanding of performing surface FES of the facial nerve in order to elicit artificial eyeblinks. The application of a biomimetic device to individuals with acute reversible facial palsy would provide immediate restoration of the periocular function and could be used until either the patient recovers sufficient function to no longer require assistance for eye closure, or the decision is made to proceed with further surgery.
