Low level laser therapy
Conventional therapy
Patients assigned to experimental group received low level laser therapy and conventional therapy. Treatment frequency was five sessions/week for 4 weeks. . For laser therapy, Omega laser system used with infrared probes of 830 nm wavelength and 100 mW output power, average energy density of 10 J/cm2 , frequency of 1 KHz, and a duty cycle of 80 % in one group. In all cases, the laser was in direct contact with the superficial roots of the facial nerve on the affected side. And was applied for 2 min and 5 s per point for 8 points.
Group B was treated with conventional therapy. The interrupted galvanic electrical impulses with the duration of 3-30 milliseconds, the tolerable intensity was applied over the motor points of each facial muscle. A total of 30-60 electrical twitch induced muscle contractions will be maintained for each muscle. The facial muscles exercise training with mirror-visual feedback was progressed to resisted exercises by self and/or therapist-assistance. All exercises were demonstrated to participants by the therapist's efforts and instructed the participants to continue the exercises twice a day for 10-15 minutes. A pictorial leaflet of facial expressions exercises with appropriate instructions to perform exercises. Treatment frequency was five sessions/week for 4 weeks.
