Background: The vestibular postural control system affects standing stability on an unstable surface. However, it is unclear whether maintaining a position different surfaces alters lateral vestibulospinal tract (LVST) excitability and body responses following stimulation. This study aimed to investigate the relationship between soleus H-reflex galvanic stimulation (GVSH), measure of LVST, post-stimulus movement while with eyes closed surfaces. Methods: Twelve healthy volunteers (mean age...

Patients with Meniere's disease (MD) often suffer from vertiginous symptoms during bad weather. Endolymphatic hydrops (EH) have been thought to be the pathological basis of MD. However, relationship between EH and weather has not clarified. space (ELS) volume can evaluated using three-dimensional analysis 3-Tesla magnetic resonance imaging (3T-MRI) after intravenous injection gadolinium enhancement. In this study, we examined correlations 24-h atmospheric pressure change day before, that is,...

Meniere's disease is a common disease, with an incidence of 15-50 per 100,000, that presents recurrent vertigo and cochlear symptoms. The pathology was first reported to involve endolymphatic hydrops in 1938. sac thought maintain the hydrostatic pressure endolymph homeostasis for inner ear. As surgical treatment intractable drainage intraendolymphatic application large doses steroids performed control preserve or improve ear function. In present study, observe effect this surgery, we...

Recently, 3-Tesla magnetic resonance imaging (MRI) with intravenous gadolinium injection has been used to reveal endolymphatic hydrops (EH). In the present study, we aimed evaluate EH in patients Meniere's disease (MD) objectively and quantitatively, compared space (ELS) individuals MD healthy controls, gain understanding of characteristics MD.Eighty-two unilateral (uMD), 16 bilateral (bMD), 47 volunteers were enrolled. All participants underwent 3-T MRI at 4 hours after injection. The...

Introduction: The present study aimed to determine whether supervised vestibular rehabilitation therapy (VRT) by physical therapists (PTs) affects subjective dizziness in patients with chronic disorders, and VRT-induced changes are related the activity levels daily life. Methods: Patients ( n = 47) peripheral disorders were randomly divided into VRT group 25) control 22). received weekly visits from PTs for a period of 6 months. Every other month, both groups advised neuro-otologists...

Background: The caloric test has been used to evaluate the semi-circular canal function for decades. In 2009, video head impulse (vHIT) was introduced, which can be within a short time. Although both tests examine canal, stimulation methods differ and it is unclear whether vHIT equivocal test.Aims/objectives: This study aimed discern differences between test.Material methods: comprised 112 patients with vertigo who visited vertigo/dizziness centre at our university hospital. Each of these...

We conducted dynamic balance or static intervention on healthy young adults to examine the changes in lateral vestibulospinal tract (LVST) excitability and postural control that ensued following investigate correlation between these changes. Twenty-eight were randomly assigned either group group. They performed a for 10 trials of 30 s each assessed head jerks during confirm adaptation intervention. The consisted maintaining horizontally unstable surface, whereas involved standing same foot...

The aim of the present study was to assess head-position management for intractable idiopathic benign paroxysmal positional vertigo (BPPV) when lying down. We hypothesized that head-up sleep (HUS) could prevent free-floating otoliths from entering semicircular canals.A prospective two-arm multicenter randomized controlled trial.BPPV diagnosed in 611 patients (611/1,520; 40.2%) according 2015 diagnostic guidelines issued by International Classification Vestibular Disorders. Among them, 201...

Body lateropulsion (BL) is an active lateral tilt of the body during standing or walking that thought to be affected by a lesion vestibulospinal tract (VST) and subjective visual vertical (SVV) tilt. Interventions for BL have not been established.

Background Sudden sensorineural hearing loss with vertigo (SHLV) and vestibular neuritis (VN) can result in prolonged dizziness.

This study aimed to clarify the prognosis of asymptomatic endolymphatic hydrops (EH) in healthy volunteers via five-year follow-ups with inner ear magnetic resonance imaging (MRI).

Modulation of the soleus H-reflex following galvanic vestibular stimulation (GVS) has been used to evaluate vestibulospinal tract function. It is not known whether this modulation because and/or cutaneous stimulation, and suitable stimulating intensity GVS for established. We investigated influence on in healthy adults. applied cathodal (at 1, 2, 3 mA) or 3-mA as a conditioning random order 17 individuals prone position with head facing forward, we examined changes right amplitude....

Background: Endolymphatic sac drainage (ELSD) may have a positive effect on endolymphatic hydrops (EH) and help to preserve inner ear function. However, the relationship between changes in EH volumes hearing function after ELSD has not been described.Objectives: We aimed reveal factors related following ELSD.Material Methods: Twenty-one patients who received were enrolled. Pure tone audiometry 3-T magnetic resonance imaging (MRI) 4 h intravenous injection of gadolinium enhancement performed...

We investigated whether noisy galvanic vestibular stimulation (nGVS) modulates the vestibulo-ocular reflex (VOR) and this effect is correlated with of nGVS on body sway. Thirty healthy young adults participated. The video head impulse test (vHIT) was used to estimate ratio eye motion velocity/head velocity VOR-gain. gain 60 ms after start (VOR-gain-60 ms) regression slope (RS) (i.e., in motion; VOR-gain-RS) were calculated. total path length foot center pressure (COP-TL) during upright...

Background: It has been reported that head-up sleep (HUS) prevents free-floating otoliths from entering canals and vertical recognition training (VRT) promotes vestibular compensation.Aims/objectives: We would like to assess HUS VRT for intractable motion-evoked dizziness, including possible benign paroxysmal positional vertigo (BPPV).Materials methods: 162 patients diagnosed with dizziness of unknown origin were enrolled randomly divided into the following four groups: HUS−/VRT−, HUS+/VRT−,...

Noisy galvanic vestibular stimulation (nGVS) is often used to improve postural stability in disorders, such as neurorehabilitation montage. For the safe use of nGVS, we investigated whether arterial pressure (AP) and heart rate vary during static supine slow whole-body tilt with random nGVS (0.4 mA, 0.1-640 Hz, gaussian distribution) a healthy elderly population. This study was conducted double-blind, sham-controlled, cross-over design. Seventeen older adults were recruited. They asked...
