Balance+Plus Videonystagmography (VNG) System
In general the Videonystagmography (VNG) is a study used to clinically evaluate patients with dizziness, vertigo, or balance dysfunction. The vestibular system monitors the position and movements of the head to stabilize retinal images. This information is integrated with the visual system and spinal afferents in the brain stem to produce the vestibulo-ocular reflex (VOR). VNG provides an objective assessment of the oculomotor and vestibular systems.
Essentially, the standard VNG test battery consists of 3 parts: oculomotor evaluation, positioning/positional testing, and caloric stimulation of the vestibular system. The comparison of results obtained from various subtests of VNG assists in determining whether a disorder is central or peripheral. In peripheral vestibular disorders, the side of lesion can be inferred from the results of caloric stimulation and, to some degree, from positional findings. In a large study of patients tested with VNG in a wide range of clinical settings, Stockwell (2000) found an abnormal test results in approximately 39% of patients tested,. Peripheral vestibular abnormalities were found in approximately 23% of patients tested, whereas central abnormalities were found in only approximately 5% of patients tested.
What are the basic components of the Balance+Plus VNG System?
While Videonystagmogrpahy is the most widely used clinical laboratory test to assess vestibular function, remember that normal VNG test results do not necessarily mean that a patient has typical vestibular function. VNG abnormalities can be useful in the diagnosis and localization of site of lesion; however, many abnormalities are nonlocalizing; therefore, the clinical history and otologic examination of the patient are vital in formulating a diagnosis and treatment plan for a patient presenting with dizziness or vertigo.
Videonystagmogrpahy offers many advantages that make it a preferred method over electrodes. Probably the most important of these advantages is that all eye movements are captured on video and can be viewed by the clinician during and after testing. In addition to capturing horizontal and vertical eye tracings, the clinician is also able to visually assess for torsional eye movement by observing the striations of the iris. This is especially important for the diagnosis of benign paroxysmal positional vertigo (BPPV).
The Balance+Plus VNG System is the first Videonystagmography (VNG) package that is truly mobile. VNG is advanced technology that can accurately evaluate patients who suffer from dizziness, vertigo or other balance disorders. The VNG System is a compact package that can easily be carried directly to your patients to assess and diagnose balance disorders.
The Goggle is the most instrumental piece of equipment for any video ENG. It should be lightweight, durable, and comfortable for your patient. We provide market-proven equipment with the most durable and shock resistant design that will hold up for years of use. It is also the most popular choice by the patient. Unlike the others, we have no light bar assembly or calibration requirements. The patient just looks into our Goggle and all the tests can be performed instantly! We offer the most streamlined and user-friendly Windows™ based software program that is the fastest test station available in the industry today.
An infrared Goggle is the most important piece of equipment for the Videonystagmogrpahy system. The patient simply looks into the Goggles and all tests are performed. The Goggle is lightweight, durable and comfortable for your patients. VNG provides accurate assessments of the oculomotor and vestibular systems. Movements of the head are analyzed with specific attention paid to retinal images.
The newly designed compact goggle system is lighter, smaller and better balanced. The House InfraRed/Video ENG System provides complete two-channel electronystagmography without electrodes. The horizontal and vertical movements of each eye are displayed, saved and analyzed by the computer-based system. In addition, rotary movements of the eyes may be observed and videotaped for documentation.
Two channel systems measuring one eye horizontally and vertically are also available. The new compact lightweight Goggle Assembly is used for spontaneous, positional, Hallpike, and rotational testing and for monitoring nystagmus during canalith repositioning. The patient is in complete darkness, providing a nonfixating environment with the eyes open.
Other manufacturers have designed complicated software systems that require continuous interaction and calibrations between tests. Their impressive software design has done very little in the way of streamlining the test procedures for the technician and patients. Our systems are more efficient and time saving as a result of a faster testing software interface.
The user-friendly Windows-based software program provides the fastest and most accurate results in the industry. Other manufacturers have designed complicated software that does not deliver the fast and accurate results that the patients and clinicians desire. The Balance+Plus Videonystagmogrpahy (VNG) System delivers more efficient results in a short amount of time.
With new Diagnostic VNG Software for Windows, the Leaders of Videonystagmography have done it again… The fastest testing software package available for VNG.
How does the Balance+Plus Fall Assessment System benefit patients and physicians?
Balance+Plus’s Fall Assessment Unit (balance plate) assesses a person’s ability to maintain their balance while standing. If your patient’s are experiencing feelings of dizziness or are unsteady, then it can help diagnose and treat your patients.
A subject simply stands on a platform, where data force sensors located at each corner of the plate collect valuable data. The data is then processed to deliver printable Stability Scores, along with other pertinent balance information. Evaluations are made with other age-matched normative reports for comparative purposes.
Balance+Plus’s software analyzes both static and dynamic balance tests by administering objective assessments with varying degrees of difficulty. The software is incredibly easy for therapists to use and they can easily utilize the built-in training modes. It delivers fast results based on the patient’s weight and the degree of difficulty of the test being administered.
All test data is stored for each patient and includes personal data, medical data, types of tests administered, the degree of difficulty and analysis of their progress. The Fall Assessment System is an incredibly invaluable tool that will help diagnose and rehabilitate your patients who are suffering from dizziness and balance dysfunctions.
