Correlation Between Cervical Spine Muscle Disorders and the Occurrence of Symptoms of Temporomandibular Joint Dysfunction

Study Overview
=================
Brief Summary
-----------------
This study evaluated the correlation between the occurrence of disorders of selected muscles of the cervical spine and the occurrence of symptoms of TMJ dysfunction

Detailed Description
-----------------
The examination includes personal questionnaire, physical examination and an algometer measurement on the upper fibers of the trapezius, levator scapula, sternocleidomastoid and rectus capitis posterior major to define pressure sensitivity of neck muscles and define is there a correlation between the occurrence of disorders of selected muscles of the cervical spine and the occurrence of symptoms of TMJ dysfunction.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Study group<br>People with temporomandibular disorder which was determined based on one of the following factors observed during the examination: acoustic symptoms, present temporomandibular joint pain, problems with opening the mouth, deviation of the jaw during abduction, or reported locking of the jaw. | Device: Algometer<br>* The algometer head was applied to the trigger point of selected muscles at an angle of 90° and, increasing the pressure at a speed of about 100g/s, three measurements were made. Each measurement stoped at the first sensation of pain<br>|
| Control group<br>People without temporomandibular disorder. | Device: Algometer<br>* The algometer head was applied to the trigger point of selected muscles at an angle of 90° and, increasing the pressure at a speed of about 100g/s, three measurements were made. Each measurement stoped at the first sensation of pain<br>|
