Study: NCT05270187

Intervention type: OTHER
Group type: EXPERIMENTAL
Intervention: Photobiomodulation therapy (laser therapy)
Description: 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.

Intervention: Facial massage and facial expression exercises
Description: 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.
