NCT06063954

Brief Summary

Bell palsy (BP) is the most common cause of acute facial palsy, which leads to functional and esthetic disturbances for patients and results in a lowered quality of life. Electroacupuncture (EA) received attention as an alternative and complementary treatment method. The low-frequency continuous wave EA and the intermittent wave EA have been used in the management of BP. The aim of this study is to compare the efficacy and safety of these two electroacupuncture waveforms for different severity groups of BP.

Outcome Measures

Primary Outcomes (1)

  • Change from Baseline score of the Facial Nerve Grading System 2.0

    Evaluation of the facial nerve function using the Facial Nerve Grading System 2.0 (FNGS 2.0). In the FNGS 2.0, the minimal score is 4, which indicates normal function, and the maximal score is 24, which indicates the worst function.

    Baseline, the end of week 4

Secondary Outcomes (2)

  • Change from Baseline score of the Sunnybrook grading scale.

    Baseline, the end of week 4

  • Change from Baseline value of the amplitude of the compound muscle action potential (CMAP) of the affected side in the ENoG test.

    Baseline, the end of week 4

Study Arms (2)

Low-frequency continuous wave group

EXPERIMENTAL

Low-frequency continuous wave EA In each treatment session, the subjects 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.

Other: electroacupuncture

Intermittent wave group

EXPERIMENTAL

Intermittent wave EA In each treatment session, the subjects 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 40Hz intermittent wave will be used for 20 min.

Other: electroacupuncture

Interventions

Electroacupuncture (EA) is a form of acupuncture in which a weak electric current is passed through the acupuncture needles into acupoints in the skin.
