Summary
The Dizziness Handicap Inventory (DHI) and Visual Vertigo Analogue Scale (VVAS) show a regular, positive correlation in assessing vestibular dysfunction. This helps understand patient quality of life impacts from dizziness.
Area of Science:
- Neurology
- Otolaryngology
- Quality of Life Research
Background:
- Dizziness is a prevalent symptom impacting quality of life.
- The Dizziness Handicap Inventory (DHI) and Visual Vertigo Analogue Scale (VVAS) are used to assess dizziness-related impairment.
Purpose of the Study:
- To correlate DHI and VVAS scores in patients diagnosed with vestibular dysfunction.
Main Methods:
- Retrospective analysis of medical records from 2006-2012.
- Pearson's correlation test was employed to analyze DHI and VVAS results.
- A significance level of p ≤ 0.05 was used.
Main Results:
- 91 patients (79.1% female, mean age 52.5) were included.
- Mean DHI score was 43.9; mean VVAS score was 5.2.
- Pearson's correlation coefficient was 0.54.
Conclusions:
- A regular and positive correlation exists between DHI and VVAS in patients with vestibular dysfunction.
- These scales effectively measure self-perceived dizziness and its impact.

7.7K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

01:29The Vestibular System
44.9K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.
