The Effect of PIR and MRT on Muscle Stiffness and Pain in Individuals With Bruxism

"Sternocleidomastoid muscle Participants are asked to stretch their necks in a spuni position and then turn their heads as far to the side of the target muscle (right side) as possible until a sensation occurs that causes discomfort in the targeted SCM. In this case, the participants are asked to moderately isometrically contract the SKM muscle for 5 seconds and then relax for 3 seconds and the cervical spine is moved to the new barrier.~Masseter muscle Participants are positioned in a sitting position. The jaw is opened as wide as possible. The index and middle fingers of one hand are placed over the lower teeth. The weight of the hand is allowed to provide flexion and traction is applied directly to the midline. In this case, the participants are asked to moderately isometrically contract the bilateral masseter muscles for 5 seconds, then relax for 3 seconds and the participant moves his chin to the new barrier."

"Sternocleidomastoid muscle The head is slightly elevated with the help of a folded towel to prevent discomfort that may develop depending on the position. The researcher sits in a chair next to the participant's head. The chair is placed at approximately 45° to the participant's neck. The participant's head is rotated 30° towards the opposite side of the treated side. The Graston instrument contacts the upper part of the SCM approximately 2 cm below the mastoid process.~Masseter muscle It works both ways. The Graston instrument is placed on the zygomatic process of the temporal bone, approximately 1 cm in front of the ear. The soft tissue is pressed until the bone is contacted. This connection with the periosteum is maintained and a lower tension line is created towards the mandible angle. This line of tension is continued up to the mandible, where the periosteum also comes into play. It is repeated several times."

Participants will rest for thirty minutes.
