Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The study included 60 patients, both sexes, aged between 19 and 40. The patients who met the inclusion criteria were alternately assigned to one of the two study groups: I group consisted of the patients received post-isometric relaxation treatment (PIR), II group - patients received myofascial release treatment (MFR). Each group consisted of 30 subjects. The series of ten treatments were performed in both groups. The comparative assessment was carried out based on the data obtained from the physical examination, physiotherapeutic examination of the masticatory system, surface electromyography (sEMG) of anterior temporal and masseter muscles and the data on the intensity of spontaneous masticatory muscle pain assessed using the Visual Analogue Scale (VAS).

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Post-isometric muscle relaxation group
The post-isometric relaxation techniques were administered to the mandibular adductors and muscles responsible for lateral movements of the mandible.
Post-isometric muscle relaxation technique
1: Therapist (T) abducted the patients' (P) mandible until the functional barrier. P performed isometric tension of the mandibular adductors with about 20% of the maximum force, balanced by the T. After 10 secs of isometric tension, P relaxed his muscles, and T abducted the mandible to a new functional barrier. During one treatment, the cycle was repeated 3 times, each time starting from the previously obtained barrier.
2: T performed passive lateral translation of the mandible until the functional barrier. P performed isometric tension with about 20% of maximum force, as to initiate the movement of the mandible towards the resting position. T balanced the force generated by the P. After 10 secs of isometric tension, P relaxed his muscles and T deepened the lateral movement of the mandible until a new functional barrier was reached. During one treatment, the cycle was repeated 3 times, both to the right and left side, each time starting from the previously obtained barrier.
Myofascial release group
The myofascial release procedure was performed successively in the area of the anterior parts of the temporal muscles, the superficial parts of the masseter muscles and the sternocleidomastoid muscles.
Myofascial release technique
The myofascial release procedure was performed successively in the area of: the anterior parts of the temporal muscles , the superficial parts of the masseter muscles and the sternocleidomastoid muscles.During one session, the above cycle was repeated six times on both sides separately. The was lying on his back, with his head turned to the side.The therapist was behind the patient's head, using the pad of the first finger placed on the skin in the area of the initial attachment of a worked muscle, he took out the tissue slack, moving the tissues towards the perceptible limitation of mobility (caudal direction).Reaching the tissue barrier, he kept the tension of the sliding structures, shifting them until the physiological tissue barrier.A single application of the myofascial release procedure consisted of one movement moving the soft tissues along the muscle
