Psychometric Properties and Concurrent Validity of a 10-Item Questionnaire for Patients With Vestibular Disorders.

Objective: This study aimed to investigate the psychometric properties and concurrent validity of the Haukeland Dizziness Questionnaire (HDQ-10), a 10-item questionnaire designed for simplified assessment of symptom severity and emotional effects in patients with vestibular disorders.

Study Design: Cross-sectional study.

Setting: Secondary referral hospital.

Frequency discrimination in ears with and without contralateral cochlear dead regions.

Objective: The purpose of this study was to test the ability to discriminate low-frequency pure-tone stimuli for ears with and without contralateral dead regions, in subjects with bilateral high-frequency hearing loss; we examined associations between hearing loss characteristics and frequency discrimination of low-frequency stimuli in subjects with high-frequency hearing loss.

Design: Cochlear dead regions were diagnosed using the TEN-HL test. A frequency discrimination test utilizing an adaptive three-alternative forced choice method provided difference limens for reference frequencies 0.
