Abstract
Purpose: Neuromuscular facial rehabilitation (NMR) using electromyographic (EMG) biofeedback has been reported to retrain muscles of facial expression by targeting increased symmetry and movement (Cronin & Steenerson, 2003, Diels & Combs, 1997; May & Schaitkin, 2000). Since denervation is a serious consequence of facial nerve damage, the present study posits that strength training may be necessary prior to EMG rehabilitation to augment blood flow and oxygen exchange and stimulate angiogenesis (growth of new capillaries) and arteriogenesis (enlargement of pre-existing vessels) for improvement in muscle performance (Yang et al, 2008). Methods: The present study examined effects of strength training in a single participant (P1; author) with right side facial nerve paresis, thirteen years post-onset, resulting from a motorcycle accident. The six and a half week, twice per day protocol targeted maximum strength training in areas served by the obicularis oris superioris (OOS), orbicularis oris inferioris (OOI), zygomaticus (ZYG), and buccal musculature (BM) using the Iowa Oral Pressure Instrument (IOPI). Lip retraction was measured using the Perry Appliance, overlay-grid, and Facial Nerve Grading System (FNGS-2). Pre- through post-therapy data from P1's affected side was compared to P1's non-affected side and an age- and gender-matched control participant (P2). Results: A significant maximum strength increase occurred in P1's right BM, and right and left OOS and OOI after six weeks of facial strengthening exercises. No significant change occurred in P1's non-affected side for the remaining facial regions, or in any of P2'sfacial regions. No significant increase in lip retraction occurred for either participant. Inter-rater reliability was highest for the Perry Appliance, followed by the overlay-grid and FNGS-2.
