Rotary Chair
RC
Description
Rotary Chair test helps doctors figure out how well your inner ear and balance system are working by looking at how your eyes react when you’re spun in a chair. If you’ve been dealing with dizziness, vertigo, or feeling unsteady, this test can provide some important answers. You’ll be seated in a motorized chair that gently rotates, and the doctor will watch how your eyes move to check how your body is responding to the motion. If your results are off, it could mean there’s an issue with your balance or inner ear function. This test is especially useful if you experience ongoing dizziness or have trouble with balance. The results help your doctor figure out the best treatment for you, whether that’s therapy, medications, or more tests. Regular testing with the Rotary Chair can help keep your balance and overall health in check.

Test Groups
Vestibular and Auditory Assessment Group: Tests in this group assess the function of the vestibular system and auditory pathways, aiding in the diagnosis of balance and hearing disorders.
Optimal Range
For All Individuals:
Result: Negative: No abnormalities detected.
Normal Range
For All Individuals:
Result: Negative: No abnormalities detected.
Results That Differ From The Norm (Direct and Indirect Causes)
Abnormal results may indicate:
Ataxias (Disorders affecting coordination and balance)
Autoimmune inner ear disease (Immune system attacks structures in the inner ear)
Benign paroxysmal positional vertigo (Brief episodes of dizziness triggered by specific head movements)
Genetic disorders
Labyrinthitis (Inflammation of the inner ear)

Key Reasons For Testing
Vestibular Function Assessment: Evaluates the vestibulo-ocular reflex and semicircular canal integrity for angular movement response.
Peripheral Vestibular Disorders Diagnosis: Identifies conditions like BPPV, vestibular neuritis, and Meniere's disease.
Central Versus Peripheral Differentiation: Distinguishes between central and peripheral vestibular dysfunctions to localize lesions.
Bilateral Vestibular Function Assessment: Quantifies vestibular asymmetries in conditions like vestibular schwannoma or bilateral hypofunction.

Important Note
Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.
Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
