Balance & Vestibular Testing
Chicagoland's Leader in Advanced Vestibular & Dizziness Diagnostics

If you have been living with dizziness, vertigo, or imbalance and still do not have answers, you are not alone, and you are in the right place.
At Northwest Speech and Hearing Center, we are the only private practice in the Chicagoland area offering this level of advanced vestibular testing.
While most clinics rely on standard testing alone, we evaluate every major component of the balance system to pinpoint the exact source of your symptoms and guide you toward the right treatment so you can feel like yourself again.
Understanding Your Balance System
Your sense of balance depends on a complex partnership between your inner ear, your vision, your muscles, and your central nervous system. When any part of this system is disrupted, even simple daily activities can feel overwhelming.
What makes dizziness particularly challenging is that symptoms like vertigo, imbalance, rocking sensations, and visual motion sensitivity can each point to very different causes. Standard testing often evaluates only a portion of the balance system, which is why so many patients spend months searching for answers.
At Northwest Speech and Hearing Center, we evaluate every major component of your balance system, not just the most common ones, so that nothing is overlooked and your diagnosis reflects the full picture of what is happening, often in a single visit.
From your first evaluation to your treatment plan, we work closely with a network of specialists throughout Chicagoland to make sure your care is as complete and connected as your diagnosis.

Conditions We Can Help With
Balance problems can have many different causes.
Our comprehensive testing helps identify what is happening so you can receive the most appropriate care.
BPPV (Benign Paroxysmal Positional Vertigo)
This is the most common cause of vertigo. BPPV happens when tiny calcium crystals in your inner ear become dislodged and move into areas where they do not belong. This causes brief but intense spinning sensations when you move your head in certain ways, such as rolling over in bed or looking up.
The good news: BPPV is highly treatable. Many patients experience significant relief in just one or two sessions through simple repositioning.
Meniere's Disease
Meniere's disease is a condition of the inner ear that causes episodes of vertigo lasting anywhere from 20 minutes to several hours. You may also experience fluctuating hearing loss, ringing in the ear (tinnitus), and a feeling of fullness or pressure in the affected ear.
While there is no cure for Meniere's disease, proper diagnosis is essential because symptoms can be managed effectively with the right treatment plan.
Central Dizziness
Sometimes dizziness originates from the brain or nervous system rather than the inner ear. This can be caused by conditions such as vestibular migraine or other neurological issues.
Our testing can help determine whether your symptoms are coming from your inner ear or may require further evaluation by a neurologist.
Cervical Dizziness
Also called cervicogenic dizziness, this condition causes both neck pain and dizziness. It can result from neck injuries such as whiplash, neck arthritis, or poor posture over time.
People with cervical dizziness often notice their symptoms are triggered or worsened by neck movement.
Fall Risk Assessment
Falls are one of the leading health concerns for adults over 60. One in three adults aged 65 or older experiences a fall each year, and many of these falls are preventable.
Our balance assessments evaluate all the systems that contribute to your stability. Identifying risk factors early can help you take steps to stay safe and maintain your independence.
POTS (Postural Orthostatic Tachycardia Syndrome)
POTS is a condition that affects your body's ability to regulate blood flow when you move from lying down or sitting to standing. This can cause dizziness, lightheadedness, a racing heart rate, fatigue, and brain fog. While POTS is not life-threatening, it can significantly interfere with daily life.
Because its symptoms overlap with many other conditions, POTS is often misunderstood or misdiagnosed. Proper vestibular testing can help determine whether your dizziness and balance difficulties are connected to POTS, so you can be directed toward the right care.
3PD or PPPD (Persistent Postural-Perceptual Dizziness)
PPPD is a condition that causes frequent dizziness most days for at least three months. Rather than spinning, the sensation often feels like swaying or rocking, and symptoms tend to worsen when you are upright or taking in a lot of visual input, such as scrolling on your phone or walking through a busy store.
PPPD usually develops after an initial episode of dizziness or balance disruption, whether that is vertigo, a vestibular migraine, or a concussion. Even after that event resolves, the brain stays on high alert for balance disruptions, making it difficult to feel steady.
Identifying PPPD is an important step, because with the right diagnosis, a personalized care plan combining vestibular rehabilitation, therapy, and when appropriate, medication, can help you find your footing again.

What to Expect During Your Assessment
We know that dealing with dizziness can be frustrating and even frightening.
Our team is here to listen, to take your concerns seriously, and to find answers.
Your evaluation will begin with a conversation about:
- Your symptoms
- Your medical history
- And the specific situations that trigger your dizziness or balance problems
Understanding your experience is essential for an accurate diagnosis.
Depending on your symptoms, your assessment may draw from our full battery of advanced tests, which includes:
Core Vestibular & Oculomotor Testing
- Standard VNG (Videonystagmography): You will wear special goggles that record your eye movements as you follow visual targets and change head positions. These foundational tests assess eye movement control, central pathways, and the lateral semicircular canals. They help differentiate peripheral vs. central causes of dizziness and identify classic disorders such as BPPV, vestibular neuritis, and cerebellar dysfunction.
Advanced Vestibular Diagnostics
- Video Head Impulse Test (vHIT) 6-Canal Assessment: You will wear lightweight goggles equipped with high-speed cameras that track your eye movements as your head is gently and briefly moved in different directions. Unlike traditional VNG, which only evaluates the two lateral canals, vHIT measures all six semicircular canals independently. This allows us to detect subtle or isolated canal deficits that calorics cannot identify, improving diagnostic accuracy for vestibular neuritis, bilateral hypofunction, and chronic dizziness.
- Advanced Dix-Hallpike with Torsional Analysis: High-resolution torsional tracking confirms true BPPV and helps distinguish it from migraine-related dizziness or central positional nystagmus. This is especially valuable for atypical, recurrent, or treatment-resistant cases.
- Lateral Head Roll Test (for Horizontal Canal BPPV): A precise method for identifying loose crystals in the horizontal canals, often missed by standard positional testing. This ensures correct canal identification and proper treatment maneuvers.
- Active Head Rotation (AHR): Evaluates the vestibular system at multiple frequencies, mirroring real-life head movements. This helps detect peripheral vestibular deficits that may not appear during slower tests like calorics.
Central & Cervical Vestibular Testing
- Smooth Pursuit Neck Torsion & Cervical Gaze Testing: Differentiates dizziness caused by neck proprioceptive dysfunction (cervicogenic dizziness) from true vestibular disorders. Essential for patients with whiplash, neck pain, or post-concussion symptoms.
- Ocular Counter-Roll (OCR): Testing
Assesses otolithic function, which is responsible for sensing gravity and tilt. This is especially helpful for patients who feel rocking, floating, or like they are on a boat without true spinning vertigo. - Saccadometry & Self-Paced Saccades: Measures higher-level eye movement control linked to frontal lobe, parietal lobe, and cerebellar function. Abnormalities can indicate central processing issues, cognitive impairment, or post-concussion dysfunction.
Electrophysiology Testing
- cVEMP (Cervical Vestibular Evoked Myogenic Potentials): Measures the function of the saccule and inferior vestibular nerve, helping identify otolithic disorders and certain types of vestibular neuritis that standard VNG cannot detect. Adds diagnostic clarity for patients with imbalance, rocking sensations, or suspected inferior nerve involvement, guiding whether treatment should target otolith pathways rather than the semicircular canals.
- oVEMP (Ocular Vestibular Evoked Myogenic Potentials): Evaluates the utricle and superior vestibular nerve pathways, providing insight into disorders affecting gravitational perception and head-tilt sensitivity. Helps differentiate utricular dysfunction from canal-based disorders, improving accuracy in diagnosing chronic dizziness, persistent postural-perceptual dizziness (PPPD), and post-concussion imbalance.
- Electrocochleography (ECoG): Measures electrical activity in the inner ear to detect Ménière's disease, endolymphatic hydrops, and other fluid-pressure abnormalities. Provides objective evidence of inner-ear fluid imbalance, helping triage patients toward medical management, dietary modification, or ENT referral when appropriate.
Functional Performance Testing
- Dynamic Visual Acuity (DVA): Determines how well the eyes stay focused during head movement. This test directly correlates with real-world symptoms like difficulty reading signs while walking or driving.
- Gaze Stabilization Test (GST): Measures the speed at which the vestibulo-ocular reflex (VOR) can keep vision stable. Helps guide vestibular rehabilitation by identifying the exact thresholds where symptoms begin.
- Functional vHIT (fvHIT): A real-world version of vHIT that evaluates how the vestibular system performs during active, functional head movements. Excellent for athletes, workers, and patients returning to daily activities.
Why Some of Our Advanced Vestibular Tests Are Self-Pay
Our goal is to give you answers, not guesswork. These advanced tests allow us to pinpoint the exact source of your dizziness, often in a single visit.
Insurance typically covers only basic vestibular testing, which evaluates a limited portion of the balance system. But dizziness and imbalance often originate from areas that standard testing simply cannot reach, including other canals, the otolith organs, the neck, and central pathways.
Our advanced tests:
- Provide far more precise diagnostic information
- Identify problems that standard VNG misses
- Reduce the need for multiple specialist visits
- Prevent unnecessary imaging
- Allow us to create a targeted, effective treatment plan immediately
Because these technologies are newer and more specialized, they do not yet have standard insurance billing codes. Rather than passing unexpected costs on to you, we offer them as transparent, affordable self-pay services so you can access the most accurate testing available without surprise costs.
Patients consistently tell us that the clarity and direction they gain from these tests are worth far more than the modest out-of-pocket fee, especially after months or years of searching for answers.
