Study on the Optimal Waveform Patterns of Electroacupuncture Targeted Intervention for Bell's Palsy Based on Surface Electromyography Characteristics
Sponsor: The Third Affiliated hospital of Zhejiang Chinese Medical University
Summary
The goal of this clinical study is to find out whether different electronic acupuncture wave forms can effectively treat recovery-stage Bell's palsy in adults and evaluate their safety. The main questions it aims to answer are: * Can targeted electronic acupuncture wave forms improve facial nerve function in patients with Bell's palsy? * What is the optimal electronic acupuncture waveform for different degrees of facial nerve injury? * What adverse events may occur during electronic acupuncture treatment? Researchers will compare low-frequency continuous wave electronic acupuncture and intermittent wave electronic acupuncture to determine which waveform works better for recovery-stage Bell's palsy. Participants will: * Receive either low-frequency continuous wave electronic acupuncture or intermittent wave electronic acupuncture every other day for 4 weeks * Undergo surface sEMG and ENoG examinations at baseline, Week 2, and Week 4 * Complete facial function assessments and safety evaluations at each clinic visit

The non-severe injury group was randomly divided into two subgroups: one treated with low-frequency continuous wave and the other with intermittent wave.The severe injury group was also randomly divided into two subgroups: one treated with low-frequency continuous wave and the other with intermittent wave.
