The development of the preliminary (37 items) and final versions (25 items) of the DHI are described. With the exception of the physical subscale, the mean values for DHI scale scores increased significantly with increases in the frequency of dizziness episodes. The 25-item Dizziness Handicap Inventory (DHI) was developed to evaluate the self-perceived handicapping effects imposed by vestibular system disease. The final version of the DHI was administered to 106 consecutive patients and demonstrated good internal consistency reliability. Cronbach's α coefficient was employed to measure reliability based on consistency of the preliminary version. The items were subgrouped into three content domains representing functional, emotional, and physical aspects of dizziness and unsteadiness. Dizziness is a common complaint in adult and geriatric populations and it is often used to describe the sensations of vertigo, like light headedness, presyncope, disorientation and/or gait instability. Answer each question as it pertains to your dizziness problem only. Bottom score is 0 (no perceived disability). Top score is 100 (maximum perceived disability). Please answer yes, no, or sometimes to each question.

DIZZINESS HANDICAP INVENTORY (DHI) Instructions: The purpose of this questionnaire is to identify difficulties that you may be experiencing because of your dizziness or unsteadiness. DATE: PATIENT: DATE OF BIRTH: Instructions: The purpose of this scale is to identify difficulties that you may be experiencing. DIZZINESS HANDICAP INVENTORY FOLLOW-UP AND DISCHARGE. The 25-item Dizziness Handicap Inventory (DHI) was developed to evaluate the selfperceived handicapping effects imposed by vestibular system disease. There is a maximum score of 100 (28 points for physical, 36 points for emotional and 36 points for functional) and a minimum score of 0. Conventional vestibulometric techniques are inadequate for quantifying the impact of dizziness on everyday life. The DHI is a 25-item self-report questionnaire that quantifies the impact of dizziness on daily life by measuring self-perceived handicap.(2) Material and methods: This observational study included. The aim of this study was to identify the subscales of DHI that may correlate with some vestibular or nonvestibular dysfunctions. The Dizziness Handicap Inventory demonstrated to be useful to assess patient outcomes and can assist in making treatment goals and outcomes more patient focused and measurable. The Dizziness Handicap Inventory (DHI) is widely used in the assessment of dizziness-related disability, but its clinical efficacy needs further expansion. The significant improvement in scores demonstrated that following vestibular rehabilitation, patient perceived outcomes improved. A significant difference in score change was determined in 57% of the patients. The development of the vanderbilt pediatric dizziness handicap inventory for patient caregivers (DHI-PC). Statistically significant improvements in Dizziness Handicap Inventory total and sub-scores were determined following vestibular rehabilitation. McCaslin DL, Jacobson GP, Lambert W, English LN, Kemph AJ (2015). Patient outcomes were assessed by comparing Dizziness Handicap Inventory total and sub-scores before and after physical therapy intervention using the Sign test at the. felt before and after they had received physical therapy intervention. Subjects answered the Dizziness Handicap Inventory based on how they. Forty-nine former patients of a vestibular rehabilitation program participated in a phone survey following vestibular rehabilitation. This study assessed patient outcomes following vestibular rehabilitation, using the Dizziness Handicap Inventory. The Dizziness Handicap Inventory is a disease-specific questionnaire used to measure how vertigo affects an individual's quality-of-life. The DHI-N was answered as part of a more extensive physiotherapy examination prior to a program of vestibular rehabilitation. Vertigo, which may be caused by a variety of problems, is a significant symptom in patients with vestibular disorders.
