Interventions
High-intensity laser therapy (HILT)
* Pulsed high-intensity laser therapy (HILT) will be applied 3 sessions per week for 8 weeks with pulsed emission (1064 nm), very high peak power (3 kW), a short duration (120-150 ms), and low frequency (10-40 Hz).The probe is fixed vertically at 90° to the most painful points while the patients sit on a chair and wear safety eyewear. * Conventional treatment ( 3 days per week for 8 weeks).: in the form of * Hot pad: It will be used over the temporomandibular joint (TMJ) for 5 minutes at the beginning of each session. * Ultrasound therapy (US): it will be applied over the TMJ with pulsed intensity of 1.0 W/cm2 at a 1MHz frequency for 5 min/session. * TENS: one electrode is placed over the TMJ and the other just above the mandibular angle. it will be applied with a low frequency of 50 HZ, tolerable intensity for 15 minutes. * Exercise therapy: anterior, medial and lateral glide of the mandible. Each glide will be done 10-15 repetitions, 5-6 times in a session, 10 minutes as a total.
placebo high-intensity laser therapy
The same treatment procedure will be applied in the placebo group as in the experimental group, but the laser device is turned off during applications, in addition to the conventional treatment in the form of hot pad, US, TENS, and exercise therapy.
