Muhtasari	The Dizziness Handicap Inventory (DHI) is a 25-item self-report questionnaire designed to measure the functional, emotional, and physical effects of dizziness and balance disorders on daily life. Developed by Jacobson and Newman in 1990, it has become a standard tool for assessing dizziness-related handicap in clinical and research settings. The DHI is valuable for tracking disability progression and treatment response in vestibular patients.	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.
