Abstract: Abstract：Objective To investigate the therapeutic effect of modulated medium frequency current therapy (MMFCT) combined with infrared therapy on patients of acute facial neuritis. Methods A total of forty-six patients with acute facial neuritis were divided into two groups (observation group and control group) randomly and medially. Every patient received medication. Meanwhile, observation group received MMFCT and infrared therapy. Before the treatment, and after two and four weeks of treatment, Portmann scale were used to evaluate the autonomic movements of the facial expression muscles on both sides. After 4 weeks of treatment, the outcome was evaluated by House- Brackmann facial nerve grading system. Results There were no significant differences in Portmann scales before treatment between two groups. Portmann scales were higher in observation group than those of control group after two and four weeks of treatment (P＜0.05). With the duration of treatment, Portmann scales were increased successively in two groups. The significant difference was found in multiple comparisons between groups. After 4 weeks of treatment, the efficacy was significant in the observation group, compared with control group, the difference was significant (P＜0.05). Conclusion Modulated medium frequency current therapy combined with infrared therapy have a better effect than isolated medication.
