Understanding Vestibular & Balance Testing

Vestibular testing plays a key role in diagnosing balance-related conditions. These tests assess how well the inner ear and brain work together to maintain stability. By evaluating eye movements, body positioning, and inner ear responses, specialists can pinpoint balance issues. Identifying these problems early allows for more effective treatment and symptom management.

Why Balance Testing is Important

Balance testing is critical for individuals experiencing dizziness, vertigo, or unsteadiness. These symptoms can make daily activities challenging and increase the risk of falls. Left untreated, balance disorders may affect mobility, independence, and overall well-being. Testing helps determine the root cause and guides appropriate treatment. Common balance disorders include vestibular migraines, Meniere’s disease, and benign paroxysmal positional vertigo (BPPV).

Do You Experience These Symptoms?

Balance disorders can cause various symptoms, affecting movement, vision, and coordination. If you experience any of the following, testing may be beneficial:

Dizziness or Vertigo

Feeling lightheaded, disoriented, or as if the room is spinning may indicate an issue with the inner ear. Vertigo often worsens with movement, such as turning your head quickly or standing up too fast. Some individuals also experience a floating sensation.

Frequent Falls or Imbalance

Difficulty walking in a straight line, frequent stumbling, or needing support to stay steady may signal a balance problem. Inner ear dysfunction can interfere with coordination, making simple tasks more challenging. This increases the risk of falls and potential injuries.

Nausea or Visual Disturbances

Many people with vestibular disorders experience motion sickness, nausea, or difficulty focusing on objects. Blurred vision or sensitivity to light and motion can make reading or driving difficult. These symptoms often worsen in crowded spaces or while using screens.

Difficulty Focusing or Hearing Issues

Some vestibular conditions affect both balance and hearing, leading to trouble concentrating. Ringing in the ears (tinnitus) or fluctuating hearing loss may accompany dizziness. Individuals may also have difficulty processing conversations, especially in noisy environments.

What to Expect During Your Testing

Understanding what happens during balance testing can help ease concerns. The process involves a detailed evaluation to pinpoint the cause of symptoms.

Review of Medical History and Symptoms

Specialists will ask about past medical conditions, medications, and recent injuries. Patients will also describe their symptoms, including when they started, what worsens them, and how they impact daily life. This information helps guide the selection of specific tests.

Series of Diagnostic Tests

Balance testing includes multiple evaluations to assess different aspects of vestibular function.

Videonystagmography (VNG)

This test tracks eye movements to determine how the inner ear and brain communicate. Patients wear special goggles while following moving lights or changing head positions. Abnormal eye movements can indicate vestibular dysfunction.

Posturography

This test measures how well an individual maintains balance under different conditions. Patients stand on a moving platform while responding to visual and physical cues. The results help assess coordination and sensory input from the eyes, ears, and muscles.

Vestibular Evoked Myogenic Potentials (VEMP)

This test evaluates how the inner ear and muscles respond to sound. Small electrodes on the neck or eyes detect muscle activity triggered by specific sounds. The results can identify weaknesses in the balance system.
