Brief Summary

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

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. Without treatment, 30% of patients with complete paralysis will not completely recover. Therefore, shortening the recovery time will accelerate the recovery process leading to better results.

The objective of this study was to determine whether photobiomodulation therapy with laser acupuncture therapy could relieve symptoms in patients with Bell's palsy.

Methods:

This study was an open-label, randomized controlled trial including 96 patients that undergoing Bell's palsy. All the patients received oral vitamin B1.

Patients were assigned to the laser acupuncture (LA) group and control group, with 102 patients in each group. LA group were received 4 weeks of Laser treatment (3 times per week), while control group were received sham laser treatment.

Clinical outcome measure comprised the House-Brackmann grading system, Facial Clinimetric Evaluation Scale (FaCE), Sunnybrook facial grading scale (SBFG), and electrophysiological testing, including Electroneuronography (ENoG), Electromyography (EMG) and Blink Reflex. All the measurements were collected at the first day and at the end of study. All reported P values were two-sided and were declared statistically significant when less than 0.05.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Laser acupuncture Group

LA group used a class IV Multiwave Locked System (MLS) laser (Mphi laser, ASA Srl, Vicenza, Italy). MLS laser is a class IV NIR laser with two synchronized sources (905 nm with 75 W peak power, pulsed mode; 808 nm with power 1 W, continuous mode). Both laser beams were synchronized, the locked waves work with the range 1-2000 Hz.

In LA group, based on clinical experience, 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 7 acupoints, including LI4 (He Gu), LI11(Qu Chi), ST25 (Tian Shu), ST36 (Zu San Li), SP6 (San Yin Jiao), KI3 (Tai Xi), LR3 (Tai Chong). The acupoints in the limbs and trunk area, were applied bilaterally. Power of laser device is 50%.

Oral vitamin B1.

Group Type EXPERIMENTAL

MLS laser

Intervention Type DEVICE

Treatments were performed with MLS laser (Mphi laser, ASA Srl, Italy). MLS laser is a class IV NIR laser with two synchronized sources (laser diodes). The first one is a pulsed laser diode, emitting at 905 nm, with 25 W peak power. The second laser diode (808 nm) was operated in a continuous mode with power 1 W. Both of the laser beams were synchronized, the locked waves work within the range 1-2000 Hz.

Oral vitamin B1

Intervention Type DRUG

Oral vitamin B1 10mg, times/day
