Introduction. The biomechanical connection of the stomatognathic system (SS) with anatomical structures within the head, neck, shoulder girdle, and even with the whole musculoskeletal system signals the need for an interdisciplinary approach to the treatment of dysfunctions of this system.
Objective. Assessment of mobility of the temporomandibular joints and cervical spine in patients with masseter muscle pain. Determination of the relationship between the mobility of the temporomandibular joints and cervical spine. Assessment of bioelectrical activity (sEMG) of masseter muscles in patients with myogenic disorders of the stomatognathic system.
Material and methods. Fifty women (G I) aged 20 to 37 years with diagnosed myogenic disorders of the stomatognathic system and pain were studied. The following examinations were carried out: interview (questionnaire) and physical examination (examination of the stomatognathic system according to Bouman, sEMG of masseter muscles, evaluation of cervical spine mobility, numerical pain scale). The control group (G II) consisted of 50 healthy women.
Results. The level of pain intensity in the masseter muscles was close to the intensity of pain within the sternocleidomastoid muscles. In patients suffering from pain of the stomatognathic system, there was a limited range of mobility of the cervical spine. The largest difference occurred during the rotation of the head to the right and to the left. Between G I and G II, there were statistically significant differences in the values of the masseter muscle sEMG amplitude.
Conclusions. There is a relationship between the limitation of movements of the mandible (opening, lateral movements) and a decrease in the range of mobility of the cervical spine. Myogenic disorders of the stomatognathic system may lead to disturbances in the mobility of the neck.
