Brief Summary
This study aims to investigate the effects of forward head correction exercises on EMG of masticatory and cervical muscles in patients with temporomandibular disorder. The study's design will be double-blinded, randomized controlled trial. Patients suffering from TMD will be included in the program. The participants will allocate to one of two groups at random: the experimental group will perform a program consisting of two strengthening exercises (deep cervical flexors and shoulder retractors) and two stretchings (cervical extensors and pectoral muscles) and the control group will receive only neck flexion exercise.. This exercise program will be repeated 4 times per week for 10 weeks, and each session lasted for 30 minutes. The muscle activity EMG of masseter, temporalis, splenius, upper trapezius, and SCM will be measured pre and post-assessment using a biopic data acquisition system.

Outcome Measures
Primary Outcomes (1)
EMG activity
Electrodes will placed on the muscle belly parallel to the direction of muscle fibers. The distance between the two electrodes was 2 cm. The subjects will instructed to complete maximum voluntary contraction (MVC) of clenching the teeth for a period of 3 s and repeated twice. The average of the two trials of MVC will used for further analysis. target muscles include masseter , temporalis, splenius, upper trapezius and sternocleidomastoid muscles.
10 weeks
Secondary Outcomes (2)
Measurement of TMJ range of motion.
10 weeks
Fonseca's questionnaire

Any study records that identify patient will be kept confidential. The records from the participation may be reviewed by people responsible for making sure that research is done properly, including members of the BAU Institutional Review Board. All of these people are required to keep their identities confidential. Otherwise, records that identify patients will be available only to people working on the study. • We will use a code of numbers and alphabets rather than participants' names on data sheets, keeping records in a safe place.
