Objective: To determine the effect of facial neuromuscular re-education over conventional therapeutic measures in improving facial symmetry in patients with Bell's palsy. Design: Randomized controlled trial. Setting: Neurorehabilitation unit. Subjects: Fifty-nine patients diagnosed with Bell's palsy were included in the study after they met the inclusion criteria. Patients were randomly divided into two groups: control (n = 30) and experimental (n = 29). Interventions: Control group patients received conventional therapeutic measures while the facial neuromuscular re-education group patients received techniques that were tailored to each patient in three sessions per day for six days per week for a period of two weeks. Main measures: All the patients were evaluated using a Facial Grading Scale before treatment and after three months. Results: The Facial Grading Scale scores showed significant improvement in both control (mean 32 (range 9.7-54) to 54.5 (42.2-71.7)) and the experimental (33 (18-43.5) to 66 (54-76.7)) group. Facial Grading Scale change scores showed that experimental group (27.5 (20-43.77)) improved significantly more than the control group (16.5 (12.2-24.7)). Analysis of Facial Grading Scale subcomponents did not show statistical significance, except in the movement score (12 (8-16) to 24 (12-18)). Conclusion: Individualized facial neuromuscular re-education is more effective in improving facial symmetry in patients with Bell's palsy than conventional therapeutic measures.
