Brief Summary

Background: Idiopathic Bell's palsy (IBP) is a unilateral facial paralysis of sudden onset and unknown etiology. Patient with IBP has an impaired facial expressions and psychological affection, which interfere with social communication. Multiwave locked system (MLS) laser therapy is a class IV laser with synchronizes emission of an 808 nm continuous laser and a 905 nm pulsed laser. It is proposed that MLS facilitates greater penetration and therapeutic effects than low-level laser therapy (LLLT). Aims: The aim of present study is to investigate the effect of MLS laser in the treatment of patients with unilateral IBP. Participant: A total number of 60 patients with IBP will be recruited from Makkah hospitals. Treatment will begin in the subacute phase as they referred from neuro-doctors. All the recruited patients will be randomly assigned into three groups of 20 patients each. Intervention: All patients will be treated with facial massage and exercises. In addition, group one will receive MLS laser with 10 J/cm2 in scanning mode while the group two will receive 10J/point for eight points. Measured variables: Facial disability scale (FDI) and House-Brackmann scale HBS will used to assess the grade of facial nerve recovery. The scores of both questionnaires will be collected at the baseline, after three and six weeks after treatment. Statistical Analysis: The Friedman and Wilcoxon signed ranks tests will be used to compare the FDI and HBS scores within each group

Outcome Measures

Primary Outcomes (3)

  • Facial disability scale (FDI)

    The FDI was produced by Van Swearingen and Brach to improve the assessment of facial neuromuscular dysfunction. Beyond the impairment domain, this index provides a reliable measurement with construct validity for evaluating patients with facial nerve disorders.

    The scores of the questionnaire will be collected at the baseline before treatment.

  • Facial disability scale (FDI)

    The FDI was produced by Van Swearingen and Brach to improve the assessment of facial neuromuscular dysfunction. Beyond the impairment domain, this index provides a reliable measurement with construct validity for evaluating patients with facial nerve disorders.

    The scores of the questionnaire will be collected after three weeks after treatment.

  • Facial disability scale (FDI)

    The FDI was produced by Van Swearingen and Brach to improve the assessment of facial neuromuscular dysfunction. Beyond the impairment domain, this index provides a reliable measurement with construct validity for evaluating patients with facial nerve disorders.

    The scores of the questionnaire will be collected after six weeks after treatment.

Secondary Outcomes (3)

  • House-Brackmann scale (HBS)

    The scores of the questionnaire will be collected at the baseline before starting of the treatment

  • House-Brackmann scale HBS

    The scores of the questionnaire will be collected after three weeks after treatment.

  • House-Brackmann scale HBS

    The scores of the questionnaire will be collected after six weeks after treatment.

Study Arms (3)

Scanning Gorup

EXPERIMENTAL

Patients in this group will receive facial massage, facial expression exercises and a Multiwave Locked System Laser with energy density 10 J/cm2. Laser will scan the affected side after calculating the distance and the total energy delivered to the one side of the face. The average treatment area is 50 cm2. The energy density was 10 J/cm2 with a total energy of 500 J and the treatment time is approximately 15 minutes. The laser probe will be away from the eye region. Both patients and therapist wear a laser googles.

Other: Photobiomodulation therapy (laser therapy)Other: Facial massage and facial expression exercises

Point laser Group

EXPERIMENTAL

Patients in this group will received facial massage, facial expression exercises and laser at predetermined eight points on the affected side of the facial muscles. the hand piece is positioned perpendicular to 8 points which is located on the superficial roots of the facial nerve of the affected side. Each point will receive an energy density of 10 J/point with total energy delivered to the patient during one session of 80 joules. The time of application 90 sec/point. laser is calibrated by the manufacture company before the starting the experiment and periodically during the sessions. The laser probe will be away from the eye region. Both patients and therapist wear a laser googles.

Other: Photobiomodulation therapy (laser therapy)Other: Facial massage and facial expression exercises

Control Group

PLACEBO COMPARATOR

patients in this group will receive only facial massage, facial expression exercises and placebo laser. Facial expression exercises include active graduated strengthening exercises in front of a mirror (active assisted, freedom, and resisted), proprioceptive neuromuscular facilitation exercises for facial muscles, and resisted exercises for neck muscles. Participants are taught to perform massage and exercises correctly by the physiotherapist. All treatment groups are given instruction to repeat the massage and exercises two times a day for at least 6 weeks. The patient or one of his/her family members will confirm that the participant carries out the massage and exercises at home.

Other: Facial massage and facial expression exercises

Interventions

The Multiwave Locked System Laser will treat both the scan and point application groups. M6 laser equipment (ASA, Arcugnano, Italy) is used in this study in the physiotherapy and rehabilitation department, Faculty of Applied Medical Science, Umm Al-Qura University. It provides synchronized and overlapping continuous and pulsed emissions of Ga-Al-Ar laser emitted in a single hand piece. M6 has a continuous emission of a wavelength of 808 nm with peak power of 1000 mW, mean power of 500mW, spot diameter of 2 cm, and spot area of 3.14 cm2. Pulsed emission has a wavelength of 905 nm, peak power of 25 W, and mean power of 54mW with frequency of 1500 Hz.

Point laser GroupScanning Gorup

Facial massage and facial expression exercises will be applied for all patients in the three treatment groups. It includes simple facial expression exercises, active graduated strengthening exercises in front of a mirror (active assisted, freedom, and resisted), proprioceptive neuromuscular facilitation exercises for facial muscles, and resisted exercises for neck muscles. Participants are taught to perform massage and exercises correctly by the physiotherapist. All treatment groups are given instruction to repeat the massage and exercises two times a day for at least 6 weeks. The patient or one of his/her family members will confirm that the participant carries out the massage and exercises at home.

Masking Details
By sealed envelopes, the allocation concealment will be achieved. Patient randomization is performed simply by computer number generator for each patient using GraphPad software. All eligible participants will be evaluated by independent physician and will be treated by the same therapist. The physician conducts the processes of participant enrollment, and allocation. The same assessors will measure the measured outcome. Both the therapist and the assessor will be blinded (masked) from patient's enrollment into the three study groups.
