Brief 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 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.

Study Groups

Laser acupuncture Group

Steroids. 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.

Steroids

Intervention Type: DRUG

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.

Sham laser acupuncture Group
