Rotary Chair

The NeuroEquilibrium Rotary Chair is an advanced, fully automatic, and computer-controlled system designed to assess vestibular function with high precision. This test is especially useful in vestibular testing in children. It provides controlled and standardized vestibular stimuli making it a fully automated tool.

Tests Included

Sinusoidal Harmonic Acceleration (SHA) Test: Evaluates VOR by measuring responses to sinusoidal rotations.
Velocity Step Test: Assesses VOR by measuring responses to sudden changes in rotational velocity.
Spontaneous Nystagmus: Detects and measures involuntary eye movements to evaluate vestibular function.

Features

Integrated Wireless with VNG: Combines with NeuroEquilibrium VNG for enhanced diagnostic capabilities
Fully Automatic: Computer-controlled operation for precise and consistent testing.
PLC and Servo Control: Ensures accurate and reliable performance.
Safety Features: Includes emergency stop switch, over-speed cut-off, and high torque cut-off for maximum safety.
Automated Calculations:
- Gain & Gain Symmetry: Automatically calculated in the Sinusoidal Harmonic Acceleration (SHA) test.
- Time Constant: Automatically calculated in the Velocity Step Test.
Calibrated VOR Assessment: Provides accurate Vestibulo-Ocular Reflex (VOR) assessment, well tolerated even by young children.

NeuroEquilibrium Rotary Chair offers an advanced, safe, and reliable method for evaluating vestibular function, ensuring precise diagnosis and effective treatment planning.

Frequently Asked Questions

How long does a rotary chair test take?

A rotary chair test typically takes about 30 to 45 minutes to complete. This includes preparation time, the actual testing, and short breaks if needed. During the test, the patient sits securely in a motorized chair while eye movements are recorded. The procedure is controlled, non-invasive, and designed to accurately assess balance function without prolonged discomfort.

What is the difference between a rotary chair and VNG?

The main difference between a rotary chair test and VNG is how they stimulate and assess the vestibular system. VNG evaluates balance using head movements, visual tracking, and ear stimulation, while the rotary chair uses precise rotational movements. Rotary chair testing is especially useful for detecting bilateral or subtle vestibular deficits that may not appear clearly on VNG alone.

What is the rotary chair test for BPPV?

The rotary chair test is not primarily used to diagnose BPPV. BPPV is usually identified through positional tests like the Dix–Hallpike maneuver. However, rotary chair testing can help evaluate overall vestibular function if symptoms persist or if the diagnosis is unclear. At advanced centers like Neuroequillibrium, it may be used alongside other tests for a comprehensive assessment.

What does vestibular testing tell you?

Vestibular testing provides detailed information about how well the inner ear and brain work together to maintain balance and stable vision. It helps determine whether dizziness or imbalance is caused by one ear, both ears, or central pathways. The results guide accurate diagnosis and treatment planning, which is why comprehensive testing is offered at specialized clinics such as Neuroequillibrium.

What are some general signs of poor vestibular function?

General signs of poor vestibular function include frequent dizziness, unsteadiness while walking, blurred vision during head movement, and difficulty maintaining balance. Some people may feel disoriented in busy environments or experience frequent falls. These symptoms can interfere with daily activities and often indicate that the balance system is not processing movement information correctly.
