The research evaluates correlation between cervical myogenic trigger zones of particular neck muscles and disequilibrium. Two groups participated in the research: relevantly healthy individuals and individuals with revealed cervical trigger zones of neck muscles. Both groups were examined once and under the same conditions using stabilographic tests. It is shown that the equilibrium indexes correlate with cervical trigger zones. In particular, it is shown that the presence of trigger zones considerably reduces the balance function by Romberg test. The upper portion of trapezoid muscle has comparatively slighter impact on individual’s stability, compared with other neck muscles. It is supposed that other cervical factors affect equilibrium.

Key words: cervical vertigo, disequilibrium, myogenic trigger zone, vestibule-cervical reflex, equilibrium function index.
