Types of Balance Test Machines
1. Videonystagmography (VNG)
Videonystagmography is a method used to assess the function of the inner ear and the central motor pathways responsible for eye movement. It employs specialized goggles equipped with infrared cameras to track eye movements during various tests. This method is beneficial for diagnosing vestibular disorders and understanding how patients’ balance systems respond to visual stimuli.
2. Video Head Impulse Test (vHIT)
The vHIT is a high-frequency test designed to evaluate the vestibulo-ocular reflex (VOR). By assessing how the eyes respond to rapid head movement, clinicians can determine the functionality of all six semicircular canals in the vestibular system. This test is particularly useful for diagnosing conditions such as vestibular neuritis or BPPV.
3. Rotary Chair Testing
This method provides an objective assessment of vestibular function through controlled rotations. Patients are seated in a chair that spins while their eye movements are monitored. This testing is vital for understanding complex vestibular disorders and is often used when other tests yield inconclusive results.
4. Force Plate Systems
Force plate systems, such as those offered by BTrackS™, provide quantitative data on balance and postural stability. They measure the center of pressure during static and dynamic activities, allowing clinicians to assess balance impairments and tailor rehabilitation protocols effectively.
5. Comprehensive Balance Systems
Systems like those from Bertec combine multiple testing modalities to deliver a thorough assessment of balance and mobility. These systems are designed to be flexible, allowing for customized protocols that cater to specific patient needs, making them suitable for various clinical settings.
6. Caloric Irrigators
Caloric testing evaluates the function of the horizontal semicircular canals by introducing warm or cold water/air into the ear canal. This method helps diagnose vestibular disorders by observing the resulting eye movements, providing key insights into the patient’s vestibular function.
7. Portable Balance Assessment
Portable systems are ideal for athletic training and in-field assessments. These machines maintain accuracy while being lightweight and easy to transport, making them suitable for use in various environments, including clinics and sports facilities.
