The effects of short-term vibration of latent myogenic trigger points of cowl muscles on balance were evaluated. The research was performed on 41 relatively healthy subjects, of them 32 individuals ― an experimental group (with latent myogenic trigger points of the horizontal sector of cowl muscle), 9 persons ― a control group (without the revealed trigger points). To evaluate postural balance we used stabilographic Romberg test. The research conditions complied with the requirements to stabilographic test. Muscle vibration was performed once during 1 minute with vibration frequency 100 Hz. Stabilography test results were assessed prior and after the muscle vibration. According to Romberg coefficient, the subjects were divided into 3 subgroups: within normal rates, above and below norm. It was shown that vertical posture doesn’t depend on neck myogenic trigger points in cowl muscles of humans. In people with myogenic trigger zones in cowl muscles, in the subgroup with the low Romberg rate, this indicator grew up to a norm limit. It was concluded that vibration on cowl muscles, irrespective of the presence of myogenic trigger zones, activates senso-motor interactions, thus improving the Romberg test indicators.

Key words: vibration irritation of muscles, myogenic trigger point, stabilography, Romberg test.
