Videonystagmography: Tests and Equipments

Videonystagmograohy, which is abbreviated as VGN has turned out to be a benchmark in the field of technologies that are used for the purpose of testing central motor functions and functioning of the inner ear. Primarily, the movement of your eyes is used as an objective to measure the imbalance or vertigo. Thus, VGN is able to derive the most accurate results because it directly measures the movement of the eyes rather than measuring the movement of mastoid muscles that are located around the eyes. The Videonystagmography test is carried out with a help of goggles which have infrared cameras. These infrared cameras record the eye movements by magnifying them and thus generate a judgment of the state of the patient's vestibular functioning.

There are three segments in which the Videonystagmography test is divided. The initial step is designed for the patient to stare at the targeted image which is moving in a certain direction, either, horizontally or vertically. The second segment is for the purpose of positional testing. For this test, the patient has to regularly switch various; head and body positions. Then, in the end, it takes the patient through an artificial mechanism that makes the patient feel imbalanced and dizzy for a couple of minutes. They do so by releasing hot and cold air for 30 seconds in each ear consecutively. Hence, with a use of all these videonystagmography equipments for the various segments of Videonystagmography, the test result it generates is the most accurate judgment of the state of patient’s central motor balance or vestibular system. Kindly note that the Videonystagmography test is best conducted by a specialist and it is always recommended to consult a doctor to know more about the effects and benefits of the test before undergoing it.

What Are Balance Disorders?

A balance disorder is a condition that makes you feel unsteady or dizzy. If you are standing, sitting, or lying down, you might feel as if you are moving, spinning, or floating. If you are walking, you might suddenly feel as if you are tipping over. Balance disorders can be caused by certain health conditions, medications, or a problem in the inner ear or the brain. It can profoundly impact daily activities and cause psychological and emotional hardship.

Your sense of balance depends on a series of signals to the brain from several organs and structures in the body, which together are known as the vestibular system. When you move, the vestibular system detects mechanical forces, including gravity, that stimulate certain organs. These organs work with other sensory systems in your body to control the position of your body at rest or in motion. This helps you maintain stable posture and keep your balance when you’re walking or running. It also helps you keep a stable visual focus on objects when your body changes position. When the signals from any of these sensory systems malfunction, you can have problems with your sense of balance.

If you have a balance disorder, you may walk unsteadily, or stagger or fall when you try to stand up. You might experience other symptoms such as dizziness or vertigo, lightheadedness, blurred vision and disorientation. Other symptoms may be nausea, diarrhea, changes in heart rate and blood pressure, and anxiety, or panic. Balance disorder causes can be medications, ear infections, a head injury, or anything else that affects the inner ear or brain. Low blood pressure can lead to dizziness when you stand up too quickly. The risk of having balance problems increases as you get older.

Balance disorder test and diagnoses comprise hearing examinations, blood tests, an electronystagmogram or imaging studies of your head and brain. Another test called posturography is also used at times.Balance disorder treatment may include different medications, simple exercises like Epley maneuver, diet changes and vestibular rehabilitation.

Craniocorpography- An Overview

Vertigo being a very common disease is also a particularly confusing one because of the words used by the patient to describe it. It is also confusing because of the battery of tests that has to be used to establish its cause and it is all the more confusing because this one symptom can be due to a wide
range of different underlying pathologies. The clinical tests like Electronystagmography and Cranio corpography test are very helpful in the diagnosis of vertigo. 

Electronystagmography provides a permanent recording of a nystagmus and it can detect nystagmus which is not readily visible on examination otherwise. It helps to differentiate between the peripheral or central origin of vertigo and to support diagnosis and to calculate canal paresis. Cranio-corpography is cheap and easily performed the outpatient procedure when compared to the more expensive computerized dynamic posturography which is unimaginable for some patients due to the costs associated with it.

Cranio-corpography is highly efficient in detecting defects in the vestibule-spinal pathway and peripheral vestibular disorder if properly performed. CranioCorpoGaphy or CCG is a medical analysis and measurement procedure. It was developed in 1968 by German neurootologist Claus-Frenz Claussen. Cranio corpography tests give a photographic representation of the patient's movement patterns as he performs the standing and stepping tests known as the Unterberger and Romberg’s test respectively.

Sensations of rotation or dizziness and nausea are the subjective symptoms characteristic of vertiginous syndromes; nystagmus and oscillations of the head and body are the objective signs. Craniocorpography is a method for recording and measuring these oscillations rapidly and inexpensively it provides easier diagnosis, follow-up, and measurement of therapeutic effectiveness.

Testing your Dizziness And Balance Disorders

You may have problems with balance and dizziness which can go worse if you are tired or stressed. The balance organs which are present in the inner part of the ear are connected with eyes so eye movements are required to be observed with each slight movement of head position, which makes the diagnosis of the vertigo proper in the patients. It is considered the new standard for testing inner ear functions over ENG as the infrared cameras are positioned to directly track the eye movements instead of measuring mastoid muscles around the eyes which were done with the use of electrodes before.

To determine inner ear disease are affected with dizziness or not, VNG test is used. VNG tests are responsible for measuring the visual responses with use of Video Frenzel Goggles while ENG tests use electrodes. The issues of dizziness or balance disorder can be felt if the cause behind is inner ear and this test is used to determine that. Hi-tech Video Frenzel System Goggles are used in different positions when the person is looking in different directions with infrared cameras. These Video Frenzel Goggles are used to record eye movements. The Video Head Impulse Test consists of visual tasks, sitting and laying in different positions, and caloric.

The ears are then passed with cool air and warm air to determine the functioning of the inner ear in caloric testing. Infrared goggles are used for the eyes to record eye movements.

Explaining The Test For Visual Acuity

The Dynamic Visual Acuity Test assesses gaze instability by measuring the difference between head-stationary and head-moving visual acuity. Dynamic visual acuity equipment tests vision in a horizontal meridian by a rotating disc. These equipments are equipped with rotating motors and timers. Dynamic visual acuity refers to an individual's ability to see clearly during head movement. In particular, the visual function designed to identify moving targets has been studied number of times by different researchers. Visual acuity is a measure of the spatial resolution of the visual system of processing. It forms on the fact that how precisely light is focused on the retina, the integrity of the eye's neural elements, and the interpretative faculty of the brain.

It consists of two parts namely one active and other is passive. In the active part, the individual generated rotations by active movements of horizontal section. In the passive part, head impulses with random timing are delivered manually by the examiner stationed near the individual and holding with the help of standing examiner besides individual and holding his head laterally on both sides without interfering with the visual field. The head impulses consisted of brisk rotations toward the tested labyrinth and the centre head position with a starting position of a 20° to 30° turn to the contralateral side. However, there are many measures that one can take to enhance their visual acuity.

These are known to be helped with various dynamic visual acuity exercises. As we know, dynamic visual acuity enables you. Clearly see the objects while they are in quick movement. To improve this, you can read letters of different sizes from a rotating surface and change the speed accordingly.
