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.

Interventions

DEVICEAlgometer

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
