Abstract

The article deals with the features of electromyographic indicators of the soleus muscles while maintaining a upright position in people with increased vestibular sensitivity. From the literature, it is concluded that the study of electromyographic features of indicators in the conditions of irritation of the vestibular analyzer in people with different vestibular sensitivity is an important area in physiology. Vestibular sensitivity was determined by the questionnaire, Voyachek's sample and Fukuda's written test. To assess the electromyographic activity of the soleus muscles, a computer DX complex was used for registration of interference electromyography. Registration was carried out during performing Romberg test, before and after vestibular loading. According to the results of the vestibular irritation, there was a greater decrease in the amplitude of the flap muscles of the lower extremities in persons with the increased vestibular sensitivity than in people with the adequate sensitivity. Based on the results achieved, it can be assumed, that in people with the increased sensitivity of the vestibular analyzer, the irritation of the receptors of the semicircular canals alters the activity of extensor motoneurons of the human spinal cord more significantly than in persons with the adequate sensitivity.
