Some Otological Aspects of the Microvibration and its Findings

Abstract

Regarding the activity of the motor-cells getting under control of the autonomic nervous system as the core of the microvibration of body surface, this phenomenon should be estimated to be the microcontraction of the striated muscle fibres, being endowed with the possibility of an objective observation of the autonomic nervous function, which is introduced from everywhere of the body surface and besides in contrast from the both bodysides.
Acoustically it has a tendency to be concerned to the individual susceptibility for the inner ear impairment by the exposure to an intense sound intensity above threshold. This microvibration disposed to have a parallelism to the individual vertiginous sensation, produced by means of the experimental caloric stimulation.
We succeeded to record the tonic neck reflex by the normal human adults, i. e. the variations of the microvibration amplitudes from the thenar side of thumb showed cleanly corresponding rise and fall to the principle of the tonic neck reflex by rotating the head.
The author stated furthermore his opinion on the bilateral difference of the microvibration in the cases of Meniere's disease
