BACKGROUND Gait function may be impaired in patients with vestibular disorders, making gait assessment in the clinical setting relevant for this patient population. The purpose of this study was to evaluate the discriminant validity of a gait assessment protocol between patients with vestibular disorders and healthy participants. Furthermore, test re-test reproducibility and the measurement err...

BACKGROUND AND PURPOSE Physical therapy interventions are often based on assumed relationships among impairments, functional performance, and disability. The purposes of this study were (1) to describe balance impairments, functional performance, and disability in subjects with unilateral peripheral vestibular hypofunction (UVH) and bilateral peripheral vestibular hypofunction (BVH), (2) to exa...

INTRODUCTION The following reports the value of new objective measures of the dynamic function of the semicircular canals and otoliths of a patient during acute unilateral superior vestibular neuritis (SVN), compared to the same objective measures 3 months later. This comparison showed that there was full recovery from the SVN. This report shows that it is possible to obtain fast, simple, accur...

Unilateral cystic inner ear anomalies were diagnosed in two siblings, a 9 year old boy and a 6 year old girl. X-ray examination of the temporal bone was performed, together with audiological examinations and vestibular function tests. The common tomographic X-ray findings consisted of an enlarged solitary sac type deformity of the vestibule with narrowing of the internal auditory canal, severe ...

BACKGROUND Although intact vestibular function is indispensable to maintaining spatial orientation, no good screening tests of vestibular function are implemented in the aviation community. High frequency voluntary head rotation was selected as a vestibular stimulus to isolate the vestibulo-ocular reflex (VOR) from visual influence. METHOD A dynamic visual acuity test that incorporates volunt...

CONTEXT Individuals with vestibular dysfunction are at increased risk for falling. In addition, vestibular dysfunction is associated with chronic pain, which could present a serious public health concern as approximately 43% of US adults have chronic pain. OBJECTIVE To assess the incidence of vestibular dysfunction in patients receiving medication for chronic, noncancer pain or other underlyi...

Introduction: Traditionally vestibular function has been assessed using caloric irrigations; new methods have failed to reach the same level of accuracy. Vestibular nerve dysfunction occurs with 'acoustic neuroma' or 'vestibular schwannoma. Quantitative testing of hearing by audiometry is much more widely available than quantitative vestibular testing, although consideration of vestibular dysfu...

INTRODUCTION There is described a transient nystagmus provoked by shaking the head in the horizontal plane for a few seconds in both normal subjects and patients that is called Head Shaking Test (HSN) as a diagnostic tool for vestibular dysfunction. HSN is generally accepted that is generated by an asymmetrical peripheral vestibular input and a central velocity storage mechanism, which integrat...
