Vertigo Symptom Scale
Also known as: VSS
The Vertigo Symptom Scale (VSS) is a self-report questionnaire assessing the frequency and severity of vertigo and associated symptoms (nausea, lightheadedness, visual disturbance, head motion intolerance). Developed by Yardley et al. in 1992, the VSS measures symptom burden rather than handicap, making it distinct from disability-focused measures. The VSS is valuable for characterizing symptom clusters, monitoring symptom progression, and evaluating treatment response in vestibular and central dizziness disorders.

When to use it
The VSS is used in vestibular clinics, neurology, and primary care for patients with benign paroxysmal positional vertigo, vestibulitis, superior semicircular canal dehiscence, migraine-associated dizziness, central dizziness, and anxiety-related vertigo. Valuable for baseline symptom characterization, monitoring treatment response (vestibular rehabilitation, pharmacotherapy, psychological intervention), and distinguishing symptom-dominant presentations from behavioral or anxious components. Useful in research evaluating interventions targeting specific symptom clusters.
Strengths & limitations
- Symptom-focused assessment complementary to impairment testing and handicap measures; captures patient-reported symptom experience directly
- Discrimination between vertigo (rotatory illusion) and non-rotatory dizziness (lightheadedness, unsteadiness); identifies symptom phenotypes
- Sensitivity to change with treatment; suitable for before-after evaluation of vestibular rehabilitation or pharmacotherapy
- Short, simple administration; no equipment required
- Validated across diverse vestibular, central, and anxiety-related dizziness populations
- Symptom frequency and severity are reported subjectively; does not distinguish peripheral from central vertigo on symptom pattern alone
- High correlation with anxiety measures; elevated VSS may reflect symptom amplification or catastrophic thinking rather than true vertigo frequency
- Does not assess triggering factors (head motion, position changes) or symptom duration; symptom episodicity not captured
- Limited normative data in asymptomatic controls; threshold scores for clinical significance vary across populations
Frequently asked
Does a high VSS score diagnose vestibular disorder?
No. High VSS indicates frequent or severe vertigo/dizziness symptoms but does not specify etiology. Peripheral vestibular disorders (BPPV, vestibulitis), central causes (cerebellar ataxia, brainstem stroke), anxiety, orthostatic hypotension, and cardiac arrhythmias all produce vertigo. Objective vestibular testing (caloric, head impulse test), imaging, and clinical history are required for diagnosis.
How is VSS distinct from the Dizziness Handicap Inventory (DHI)?
VSS measures symptom frequency and severity—what patients experience. DHI measures handicap—the functional and emotional impact of those symptoms. A patient may have low VSS (infrequent symptoms) but high DHI (symptoms cause great distress when they occur), or vice versa. Both are complementary: VSS tracks symptomatic improvement; DHI tracks functional recovery.
What does a VSS subscale pattern reveal?
High Vertigo subscale (spinning, room moving) with low Disorientation subscale suggests peripheral vestibular dysfunction (BPPV, vestibulitis). High Disorientation subscale (lightheadedness, unsteadiness, floating) with low Vertigo subscale suggests central, cardiovascular, or anxiety-related dizziness. Clinicians should combine subscale patterns with neurologic examination and vestibular testing for accurate diagnosis.
Can VSS be used to monitor response to vestibular rehabilitation?
Yes. VSS scores typically improve with effective vestibular rehabilitation as patients habituate to provocative movements and regain balance confidence. Meaningful improvement is a 10–15 point decrease. If VSS does not improve after 4–6 weeks of appropriate rehabilitation, consider non-vestibular etiology (anxiety, cardiovascular, neurologic) and reassess diagnosis.
