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

Conditions

  • Bell's Palsy

PROCEDURE

electroacupuncture waveform

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.
