This study aims to assess the effect of intradermal acupuncture(IA) and guided self-rehabilitation management program(GRMP) (either single or combined) for patients with severe Bell's Palsy.

Study Overview

Detailed Description

After confirming the details of the trial process and signing an informed consent, all participants will be randomly divided into the following four groups: Active IA+GRMP, Active IA+ HE, sham IA+ GRMP, sham IA + HE. They will receive active or sham IA and GRMP or HE until complete recovery or completion of follow up (a duration of 24 weeks).Follow-ups will be done in 4-week, 8-week, 12-week,16-week, 20-week, and 24-week.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: "Active intradermal acupuncture" plus "Guided self-rehabilitation management program"

Active IA will be retained in the acupoints for 72h before being removed, then rested for one day.Participants receive Active IA until full recovery or completion of follow up (a duration of 24 weeks).

Participants will be taught and corrected self-rehabilitation techniques by Physical Medicine and Rehabilitation(PMR) therapists at regular outpatient clinic visit (twice weekly for the first 12 weeks, then weekly until full recovery or follow-up completed) and practice at-home therapy and diarize accomplished exercises.

Depending on acupoints' location, φ0.20*1.5mm or φ0.20*1.2mm AIA will be selected. Insert the Active IA vertically into the acupoint and retain it in the skin.

Active IA will be retained for 72 hours with a day's rest after removal. During the period of needle retention, participants will be required to press the Active IA 4 times a day for approximately 1 minute each time, with as much stimulation as the patient can tolerate, at intervals of approximately 4 hours.

Self-rehabilitation techniques are taught in individual sessions of about 40 minutes at each outpatient clinic visit, as detailed below: Analysis of the problem, Education, Massage, Facial muscles exercise,Synkinesis or spasticity management, Homework. Participants are requested to perform daily facial muscle exercises as prescribed by the therapist and keep the written diary on a daily basis. The therapists retrieve and evaluate the diaries at each visit.
Experimental: "Active intradermal acupuncture" plus "Health education"

Active IA will be retained in the acupoints for 72h before being removed, then rested for one day.Participants receive Active IA until full recovery or completion of follow up (a duration of 24 weeks).

Participants will be taught health education content about the disease by PMR therapists at regular outpatient clinic visit (twice weekly for the first 12 weeks, then weekly until full recovery or follow-up completed) and have no homework and keep no daily logs.

Depending on acupoints' location, φ0.20*1.5mm or φ0.20*1.2mm AIA will be selected. Insert the Active IA vertically into the acupoint and retain it in the skin.

Active IA will be retained for 72 hours with a day's rest after removal. During the period of needle retention, participants will be required to press the Active IA 4 times a day for approximately 1 minute each time, with as much stimulation as the patient can tolerate, at intervals of approximately 4 hours.

The therapists retrieve and evaluate the diaries at each visit.
Sham intradermal acupuncture will be attached to the acupoints and retained for 72 hours with a day's rest after removal. During the period of sham needle retention,pressing times and frequencies are identical to those in the active intradermal acupuncture group.
Sham Comparator: "Sham intradermal acupuncture" plus "Health education"

Sham IA will be retained in the acupoints for 72h before being removed, then rested for one day.Participants receive Sham IA until full recovery or completion of follow up (a duration of 24 weeks).
