Objective To study the effects of the “Mirror Effect Plus Protocol” (MEPP) on global facial function in acute and severe Bell's Palsy. Design Single blind and randomized controlled trial to compare the effects of basic counseling (control group) versus MEPP (experimental group) over one year. Setting Outpatient clinic following referrals from Emergency or Otorhinolaryngology Departments. Subjects 40 patients (n = 20 per group) with moderately severe to total palsy who received standard medication were recruited within 14 days of onset. Baseline characteristics were comparable between the groups. Interventions The experimental group received the MEPP program (motor imagery + manipulations + facial mirror therapy) while the control group received basic counseling. Both groups met the clinician monthly until 6 months and at one-year post-onset for assessments. Outcome measures Facial symmetry, synkinesis, and quality of life were measured using standardized scales. Perceived speech intelligibility was rated before and after therapy by naïve judges. Results Descriptive statistics demonstrated improvements in favor of the MEPP for each measured variable. Significant differences were found for one facial symmetry score (House-Brackmann 2.0 mean (SD) = 7.40 (3.15) for controls versus 5.1 (1.44) for MEPP), for synkinesis measures (p = 0.008) and for quality-of-life ratings (mean (SD) score = 83.17% (17.383) for controls versus 98.36% (3.608) for MEPP (p = 0.002)). No group difference was found for perceived speech intelligibility. Conclusion The MEPP demonstrates promising long-term results when started during the acute phase of moderately severe to total Bell's Palsy.
