Vestibular Activities and Participation
Also known as: VAP
The Vestibular Activities and Participation (VAP) scale is a patient-reported measure designed to assess limitations in activities of daily living and restrictions in social participation resulting from vestibular dysfunction. Developed within the International Classification of Functioning, Disability and Health (ICF) framework, the VAP evaluates the 'activity' and 'participation' domains rather than impairment alone. It complements clinical vestibular testing and handicap measures (e.g., Dizziness Handicap Inventory) by capturing real-world functional outcomes and quality-of-life limitations.

When to use it
The VAP is used in vestibular rehabilitation programs, otolaryngology and neurotology clinics, and research evaluating interventions for benign paroxysmal positional vertigo (BPPV), bilateral vestibular loss, superior semicircular canal dehiscence (SSCD), Ménière disease, and vestibulitis. It is particularly valuable for assessing return-to-work capacity, evaluating participation outcomes after vestibular rehabilitation or surgery, and tracking quality-of-life improvement during long-term management. Suitable for outpatient and rehabilitation settings.
Strengths & limitations
- Aligns measurement with WHO ICF framework, capturing activity and participation dimensions rather than impairment alone—relevant to patient-centered outcomes
- Comprehensive assessment of real-world functional limitations across work, self-care, hobbies, and social domains
- Sensitive to change during vestibular rehabilitation; correlates with objective measures of balance (Dynamic Gait Index) and self-efficacy
- Complements deficit-focused testing with capability-focused assessment; enables shared decision-making around functional goals
- Validated in adult vestibular populations with strong test-retest reliability (intraclass correlation coefficient >0.85)
- Lacks standardization across publications; different VAP versions exist with varying item counts and scoring, limiting comparison between studies
- Reliant on self-perception; does not distinguish true activity limitation from anxiety-driven avoidance or depression-related withdrawal
- Does not assess balance confidence or coping strategies separately; high scores may reflect low self-efficacy rather than objective functional deficit
- Pediatric validation limited; primarily studied in adults with acquired vestibular dysfunction
Frequently asked
How does VAP differ from the Dizziness Handicap Inventory (DHI)?
The DHI measures handicap—the perceived impact of symptoms on well-being. The VAP measures activity and participation in specific functional domains. A patient with severe DHI scores may have low VAP scores if they manage their condition well and remain engaged despite dizziness. The VAP is more specific to rehabilitation outcomes and occupational function; DHI is broader in capturing emotional and functional burden.
Can VAP be used to predict return-to-work capacity?
Yes. VAP scores, particularly subscales assessing work or school activity, correlate with actual work resumption and occupational reintegration. VAP scores <30 generally indicate sufficient functional capacity for return to work or school; scores >50 suggest need for workplace accommodation or occupational rehabilitation before return.
What constitutes clinically meaningful change on the VAP?
A change of 10–15 points (depending on the version and population) is considered clinically meaningful. Improvement in specific target activities (e.g., return to gardening, resumption of commuting) is often more relevant to patients than omnibus score changes and should be tracked alongside total VAP score.
Is VAP appropriate for use in pediatric vestibular patients?
Limited pediatric-specific validation exists. Adult VAP can be adapted for older children and adolescents by modifying items to reflect school, play, and age-appropriate social activities. Consultation with pediatric rehabilitation specialists is recommended for optimal item selection and interpretation in children <16 years.
