INSTRUMENTS AND 4_^TACHMENTS FOR ELECTRONYSTAGMOGRAPHY
Candidate of Medical Sciences Yu. T. Mironenko and A. A.
Vilenskiy*
In clinical practice in order to judge the condition of the
vestibular analyzer, spontaneous vestibular disorders are detected,
and a numbe=r of experi.mcr tal tests are also made; rotational,
caloric, etc. Supplemented by :electronystagmographic recording, the
results of these studies make it possible to quantitatively assess
it,and at the same time permit a reliable judgment on the functioning
of the vestibular apparatus.
Domestic industry is not yet manufact,iring electronystagmo-
graphs. Therefore, for vestibulometry we have to use expensive
electroencephalographs or electrocardiographs that have considerable
dimensions (1, A. Sklyut, 1973), which impairs their use in the
clinic, polyclinic, and directly at the patient's bed.

We have developed a portable set of instruments and devices
that make it possible to record spontaneous nystagmus with open and /80
closed eyes, as well as rotational, caloric, position and pressure
nystagmus utzder any conditions.
The chief component in the set is the one-charnel electro-
cardiograph "Salyut-1," that has two power units, a storage battery

and circuit (fig. 1). Amplificat-Lon of the corneoretinal potential
that comes to the electrocardiograph is implemented by the alterna-
ting current preamplifier 2 that we made with time constant of 2 s
(fig. 2) .
For convenience of applying the electrodes and conducting the
calibration half-mask 3 is used with electrodes and calibrator 4
.installed in it (see fig. 1). The rim of the half-mask is made of
light-impermeable material.. The calibrator consists of protractor
5 that is secured horizontally in the center of the upper edge of the
rim and is equipped with three radial rods 0 with miniature light
sources. The lamps are powered by conductors 7 that come from the
remote control panel 8 that is equipped with battery knob switches
9. The recording of spontaneous nystagmus with open and closed eyes
in the dark is guaranteed by the covering of the visual field with
shade 10 that is fixed on the half-mask.
In order to conduct the rotational test Barani chair 1 is used
with detachable table 2, on which the electrocardiograph (with storage
battery unit) 3, preamplifier 4 are placed (fig. 3).
During the caloric test, a head rest is used that is made of
	
/81
organic glass, with angle of incline 30° in relation to the horizon-
"	 tal surface, two receptacles for water 1, made of polyethylene, and
a pipe from the system for blood transfusion 2 (fig. 4).
As an example (fig. 5) we present the electronystagmograms
of caloric nystagmus to the right 1 and to the left 2 that were

made in a patient who had radical surgery on the right ear a year
