Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Bell palsy (BP) is a relatively common clinical disease, which leads to functional and esthetic disturbances for patients and results in a lowered quality of life. Electroacupuncture received attention in the management of BP. The aim of this study is to evaluate the curative effect of different waveform of electroacupuncture on peripheral facial paralysis in subacute stage and to screen out the optimal waveform.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This parallel-group, multicenter randomized clinical trial (RCT) will be conducted at the outpatient clinic of three hospitals in China.A total of seventy-five eligible patients will be randomly divided into low frequency continuous wave(n=25) ,discontinuous wave(n=25) and dilatational wave (n=25) groups.All groups will receive traditional acupuncture treatment at selected acupoints (BL2,GB1,GB14,ST2,SI18,ST4,ST6,ST7,SJ17,EX-HN16,EX-HN5,LI4),additionally,receive different waveform of electroacupuncture treatment for 20 minutes three times per week for four weeks.Facial Nerve Grading System 2.0 (FNGS 2.0) will be used to assess the curative effect at baseline and at 4 weeks after treatment, as the primary outcome.Sunnybrook facialgrad-ingsystem(SFGS) and Facial Disability Index (FDI)Scale will be measured and analyzed at baseline and at 4 weeks after treatment, as secondary outcomes.In addition,amplitude ratio of the affected/healthy side will be another secondary outcome tested by ENoG at bsaeline.

low-frequency continuous wave group

In each treatment session, the patients will receive EA treatment. The selected acupoints for needling will be BL2, GB1, GB14, ST2, SI18, ST6, ST4, ST7, SJ17, EX-HN16, EX-HN5, on affected side, and LI4, bilaterally. After the de-qi sensation is achieved, electrical stimulator will be connected to BL2-GB1, and ST4-ST6, and 2Hz continuous wave will be used for 20 min.
