Ocular vestibular evoked myogenic potentials (oVEMPs), subjective visual vertical (SVV), and fundus photographically measured binocular cyclorotation (BCR) are diagnostic tests to assess utricular function in patients with vertigo or dizziness. In 138 chronic dizziness, we asked whether the asymmetry ratio of oVEMP (normal, right side pathological, left pathological) could predict SVV deviation...

BACKGROUND vestibular disorders are common in the general population, increasing with age. However, it is unknown whether older adults who fall have a higher proportion of vestibular impairment compared with age-matched older adult non-fallers. OBJECTIVE to identify whether a greater proportion of older adult fallers have a peripheral vestibular impairment compared with age-matched healthy co...

Much is known about age-related anatomical changes in the vestibular system. Knowledge regarding how vestibular anatomical changes impact behavior for older adults continues to grow, in line with advancements in diagnostic testing. However, despite advancements in clinical diagnostics, much remains unknown about the functional impact that an aging vestibular system has on daily life activities ...

INTRODUCTION Visual stimuli can induce vestibular adaptation and recovery of body balance. OBJECTIVE To verify the effect of visual stimuli by digital images on vestibular and body balance rehabilitation of peripheral vestibular disorders. METHODS Clinical, randomized, prospective study. Forty patients aged between 23 and 63 years with chronic peripheral vestibular disorders underwent 12 se...

introduction: patients with bilateral weakness (bw) have many difficulties in gaze stability that interfere with their normal function. the aim of this study was to evaluate ocular motor functions in patients with bw to better understand the problem of gaze instability in these patients.   materials and methods: patients were referred from the otolaryngology department for vestibular assessment...

OBJECTIVE The value of vestibular rehabilitation in patients with bilateral vestibular dysfunction was investigated. MATERIALS AND METHODS This study assessed 17 patients (9 males, 8 females) with bilateral vestibular dysfunction. Vestibular rehabilitation continued for 1.5 months. Videonystagmography tests (including oculomotor testing, positional testing, and caloric tests), vestibular evok...

Identifying unilateral vestibular failure of the semicircular canals (SCC) is important in vertigo and dizziness disease. There are different vestibular tests available: rotatory testing (RT), bithermal caloric irrigation (CI) and the video-head-impulse test (vHIT). This review comments on the current knowledge and on economic aspects of the testing methods. RT are a very specials tests and sho...

Extracellular single neuron recording and labelling studies of primary vestibular afferents in Scarpa's ganglion have shown that guinea-pig otolithic afferents with irregular resting discharge are preferentially activated by 500 Hz bone-conducted vibration (BCV) and many also by 500 Hz air-conducted sound (ACS) at low threshold and high sensitivity. Very few afferent neurons from any semicircul...

background: despite wide application of chromium in electroplating industry, the pulmonary effects of chronic exposure to this chemical have not been extensively studied and are subject of debate and controversy. this study was, therefore, undertaken to further address this issue.   methods: the study population consisted of a group of 15 workers with a history of past and present occupational ...

background: the rapidity of progression of amyotrophic lateral sclerosis (als) to death or respiratory failure impacts patients, clinicians, and clinical investigators. the aim of this study is to evaluate of the pulmonary function tests (pfts) in patients with als and the association between these pfts and survival methods: a total of 36 als patients who pfts, including vital capacity (vc), ma...
