Electroacupuncture Waveforms for Subacute Peripheral Facial Paralysis

This study aims to explore the effectiveness of electroacupuncture with different waveforms in treating subacute peripheral facial paralysis. The trial involves seventy-five patients who will be treated at outpatient clinics in three hospitals in China. Participants will be divided into three groups, each receiving a specific type of electroacupuncture waveform: low frequency continuous, discontinuous, and dilatational waves. The study is important because it seeks to identify the most effective waveform, potentially leading to better treatment options for people experiencing facial paralysis, which can significantly affect their quality of life. Participants in the study will receive traditional acupuncture at specific points on the face and additional electroacupuncture treatment for 20 minutes, three times a week, over four weeks. The effectiveness of the treatments will be assessed using the Facial Nerve Grading System 2.0 at the start and end of the four-week period. Secondary measures include the Sunnybrook facial grading system, the Facial Disability Index Scale, and an amplitude ratio test of the affected and healthy sides using ENoG. These assessments will help determine improvements in facial movement and disability. The study will provide insights into the potential benefits and effectiveness of different electroacupuncture waveforms for facial paralysis treatment.
