Clinical Trial Summary

Objective:

Bell's palsy is characterized by acute, unilateral onset that compromises function and esthetics, exerting a considerable impact on the social, professional, and psychological aspects of the lives of affected individuals. The objective of this study was to determine whether laser acupuncture therapy could relieve symptoms in patients with Bell's palsy in 8 weeks.

Methods:

This study was randomized controlled trial including 360 patients that undergoing Bell's palsy. All the patients received oral Betahistine Mesylate tablet, Vitamin B1 tablet and Prednisolone.

Patients were assigned to the laser acupuncture (LA) group, Sham LA group and control group, with 120 patients in each group. LA group and Sham LA group were received 4 weeks of Laser treatment (3 times per week).

Clinical outcome measure comprised the House-Brackmann grading system, Facial Clinimetric Evaluation Scale (FaCE), Sunnybrook facial grading scale (SBFG), Facial Disability Index (FDI) and Facial Clinimetric Evaluation Scale (FaCE Scale) All the measurements were collected at the baseline, weeks 2, 4, 6, 8, 12 and 24.

Intervention

Device:
• Laser acupuncture
Patients in the laser acupuncture group (LA group) received 12 sessions of laser acupuncture (3 times per week). Laser aucpuncture used a class IV Multiwave Locked System (MLS) laser (Mphi laser, ASA Srl, Vicenza, Italy). In LA group, we choose 5 acupoints on the affected side. It includes ST2(Si Bai), ST4(Di Cang), ST6(Jia Che), GB14(Yang Bai), GB20(Feng chi). We choose 6 acupoints, including LI4 (He Gu), LI11(Qu Chi), ST36 (Zu San Li), SP6 (San Yin Jiao), KI3 (Tai Xi), LR3 (Tai Chong). Laser acupuncture used have wavelength of 808 nm and 905nm, 1.2 W power (808nm is 1 W, 905 nm is 200 mW), continuous mode emission (808 nm) and pulsed mode emission (905 nm), 500 Hz, 50% power level, 50% duty cycle, 8.35 J/cm2 dosimetry, 26.22 J for each point, administered for 3 times per week in the first 2 weeks, and 1500 Hz, 50% power level, 50% duty cycle, 8.35 J/cm2 dosimetry, 26.22 J for each point, in the last 2 weeks, 12 times total treatment.

Drug:
• Steroids
Prednisolone as 5 mg tablets (Tianjin Lisheng Pharmaceutical Co., Ltd., China) were given as a single dose of 30 mg daily for the first 3 days; 15 mg daily for the following 3 days; 10 mg daily for the after 3 days; 5 mg daily for the final 3 days, with a total treatment time of 9 days.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	House Brackmann Grading System (HB)	The HB is a physician-rated system based on criteria of resting appearance, facial movements, and synkinesis that categorizes facial function from I (normal) to VI (total paralysis), with options of "Normal", "Mild dysfunction", "Moderate dysfunction", "Moderately severe dysfunction", "Severe dysfunction" or "Total paralysis". The prognoses of grade 3 or higher were abnormal.	Baseline, weeks 2, 4, 6, 8, 12 and 24
Secondary	Sunnybrook Facial Grading Scale (SB Grading)	The Sunnybrook Facial Grading Scale was used because of its international recognition and because it allowed a separate classification of the degree of synkinesis. The SB Grading is divided into three subscales of resting symmetry (Eye and Mouth range from 0 to 1, Cheek ranges from 0 to 2), symmetry of voluntary movement (ranges from 1 to 5), and synkinesis (ranges from 0 to 3). The three subscores are used to calculate a composite score (ranges from 0 to 100).	Baseline, weeks 2, 4, 6, 8, 12 and 24
Secondary	Facial Disability Index (FDI)	Facial Disability Index (FDI) is a brief, self-report questionnaire of physical disability and psychosocial factors related to facial neuromuscular function. The FDI is a 10-item test that is divided into physical function (ranges from 0 to 5). and social/ well-being function (ranges from 1 to 6) domains. The physical function scores range from -25 (worst) to 100 (best), and the social/wellbeing function scores range from 0 (worst) to 100 (best).	Baseline, weeks 2, 4, 6, 8, 12 and 24
Secondary	Facial Clinimetric Evaluation Scale (FaCE Scale)	FaCE is 15-items, self-reported questionnaire that used to assess facial impairment and disability after facial paralysis. It includes six independent domains: social function, facial movement, facial comfort, oral function, eye comfort, and lacrimal control. the total scores range from 0 (worst) to 100 (best).	Baseline, weeks 2, 4, 6, 8, 12 and 24
