What to Expect from a Vestibular Rehab Evaluation (And Why It's Not Like Regular PT)

If you've been dizzy for months and nobody has found answers, this is where to start.

Dizziness is one of the most common complaints in primary care, and one of the most consistently underevaluated. It gets attributed to everything from anxiety to dehydration to "just getting older." Sometimes those explanations are right. Often, they're not the whole picture.

Vestibular dysfunction, problems with the inner ear system that controls your sense of balance and spatial orientation, is behind a significant portion of chronic dizziness cases. And it's highly treatable with the right evaluation and approach. Here's what that actually looks like.

First: What Is the Vestibular System?

Your vestibular system lives in the inner ear and sends signals to your brain about head movement, position, and spatial orientation. It works in tandem with your vision and proprioception (body position sense) to keep you upright and stable. When any part of that system is disrupted, by a displaced crystal, a viral infection, reduced function on one side, your brain receives conflicting signals. The result is dizziness, spinning, unsteadiness, or visual disturbance with movement.

The most common vestibular conditions we treat at MBODY:

• BPPV (Benign Paroxysmal Positional Vertigo) — brief spinning triggered by head position changes

• Vestibular hypofunction — reduced function of one or both vestibular organs, often after illness or injury

• Persistent Postural-Perceptual Dizziness (PPPD) — chronic dizziness and unsteadiness that persists after an initial trigger

• Post-concussion vestibular dysfunction

• Vestibular migraine

What Makes a Vestibular Evaluation Different?

A standard orthopedic PT eval focuses on strength, range of motion, joint mechanics. A vestibular eval is a different skill set entirely. It requires specific training in the anatomy and physiology of the inner ear, the ability to administer and interpret clinical tests that assess the vestibulo-ocular reflex (how your eyes stabilize when your head moves), and the knowledge to determine which of many possible diagnoses best fits what you're presenting with.

At MBODY, vestibular rehab is led by our founder and clinic director, whose specialization in this area goes well beyond what a generalist PT program covers. This matters, because the wrong repositioning maneuver for the wrong canal can make BPPV worse. The right clinical reasoning matters.

What Actually Happens at the Eval?

Here's what you can expect at a vestibular evaluation at MBODY:

Comprehensive history. The evaluation starts with an extended conversation: when the dizziness started, what triggers it, how long episodes last, what makes it better or worse, what you've already tried. The pattern of your symptoms is often more diagnostically useful than any single test.

Oculomotor testing. Your therapist will assess how your eyes move, tracking a moving target, making rapid eye movements, stabilizing your gaze while your head moves. Deficits in these movements point to specific parts of the vestibular or visual system.

Positional testing. If BPPV is suspected, you'll be moved through specific positions to observe whether nystagmus (involuntary eye movement) is triggered, and to identify exactly which canal the displaced crystal is in. This determines which repositioning maneuver to use.

Balance and gait assessment. How your balance changes when you close your eyes, stand on unstable surfaces, or turn your head tells us how well your brain is compensating for any vestibular deficit.

Clinical impression and plan. By the end of the evaluation, you should have a clear explanation of what's likely causing your symptoms and a concrete treatment direction, whether that's a same-day repositioning maneuver for BPPV, a progressive vestibular adaptation exercise program, or a referral for additional diagnostics if needed.

How Long Does Treatment Take?

It depends significantly on the diagnosis. BPPV often resolves in 1–3 visits with the correct repositioning maneuver. Vestibular hypofunction typically requires a 6–10 week exercise program to facilitate brain compensation. PPPD may involve a longer, more graduated approach. Most vestibular conditions respond well to treatment, the key is accurate diagnosis first.

Why This Matters

Dizziness that isn't addressed doesn't usually just go away. It leads to activity avoidance, fall risk, anxiety, and a significantly reduced quality of life. Many clients we see have been dizzy for months or years and had been told, or resigned themselves to believing, that nothing could be done.

Something can be done. The evaluation is where it starts.
