INTRODUCTION AND AIM: The reason of gradually developing conductive hearing loss in otosclerotic patients is the ossification of the stapes footplate to the surrounding bony structures and the therapy of stapes fixation is mainly surgical. In stapedotomy the footplate of the stapes is fenestrated with laser and microdrill in a diameter of 0.8 mm, whereas in stapedectomy there is complete removal of the footplate followed by the reconstruction of the ossicular chain. In the early postoperative period, temporary vertigo is frequently recorded which significantly influences the recovery...

Patients with bilateral vestibular failure (BVF) suffer from postural and gait unsteadiness with an increased risk of falls. The aim of this study was to elucidate the differential role of otolith, semicircular canal (SSC), visual, proprioceptive, and cognitive influences on the postural stability of BVF patients. Center-of-pressure displacements were recorded by posturography under six conditions: target visibility; tonic head positions in the pitch plane; horizontal head shaking; sensory deprivation; dual task; and tandem stance...

Our objective was to assess the capability of computerized dynamic posturography (CDP) to evaluate dizziness in blind patients who lack corneoretinal potential. We performed a retrospective analysis of 2 young blind subjects with intraorbital scarring who complained of dizziness and underwent CDP. Tests were carried out at our center for balance disorders using the NeuroCom's EquiTest System version 4.0. CDP demonstrated vestibular dysfunction and revealed it to be severe. We conclude that CDP can serve as a potentially reliable tool for assessing dizziness in blind patients who have no corneoretinal potential...

Simultaneous performance of motor and cognitive tasks may compete for common brain network resources in aging or patients with some neurological diseases, suggesting the occurrence of a cognitive-motor interference. While this phenomenon has been well described for multiple sclerosis (MS) patients, it never has been tested on asymptomatic subject with magnetic resonance imaging (MRI) findings suggestive of demyelinating disease (i.e., radiologically isolated syndrome: RIS). In this pilot study, 10 RIS subjects and 10 sex/age-matched healthy controls were tested by means of static posturography under eyes opened (single-task trial) and while performing two different cognitive tasks (semantic modified word list generation for first dual-task trial and phonemic semantic modified word list generation for second dual-task trial), to estimate the dual-task cost (DTC) of standing balance...

INTRODUCTION: The effects of repeated centrifugation in association with head-down tilt (HDT) bed rest (BR) on the mediation of basic reflexes associated with the major postural muscles was investigated as a potential countermeasure for maintaining balance control and neuromotor reflex function. METHODS: There were 15 male volunteers who were exposed to 21 d of 6° HDT-BR. Eight were treated with daily 1-h artificial gravity (AG) exposures aboard a short radius centrifuge that provided 1-g footward loading at heart level...

We evaluated the therapeutic effects of anti-gravity locomotor treadmill (AlterG) training on postural stability in children with Cerebral Palsy (CP) and spasticity, particularly in the lower extremity. AlterG can facilitate walking by reducing the weight of CP children by up to 80%; it can also help subjects maintain an appropriate posture during the locomotor AlterG training. Thus, we hypothesized that AlterG training, for a sufficient period of time, has a potential to produce cerebellum neuroplasticity, and consequently result in an effective permanent postural stability...

Clinically useful and efficient assessment of balance during standing and walking is especially challenging in patients with neurological disorders. However, rehabilitation robots could facilitate assessment procedures and improve their clinical value. We present a short overview of balance assessment in clinical practice and in posturography. Based on this overview, we evaluate the potential use of robotic tools for such assessment. The novelty and assumed main benefits of using robots for assessment are their ability to assess 'severely affected' patients by providing assistance-as-needed, as well as to provide consistent perturbations during standing and walking while measuring the patient's reactions...

BACKGROUND: Leg-length inequality results in an altered position of the spine and pelvis. Previous studies on the influence of leg asymmetry on postural control have been inconclusive. The purpose of this paper was to investigate the effect of structural leg-length discrepancy (LLD) on the control of posture. METHODS: We studied 38 individuals (19 patients with structural LLD, 19 healthy subjects). The examination included measurement of the length of the lower limbs and weight distribution as well as a static posturography...

OBJECTIVE: To characterize the stability limits and region in patients with unilateral vestibulopathy according to the side of the lesion and determine if that imposes any bias. To analyze if the stability limits and region depend on the functional deficit as evaluated in the sensory organization test. METHODS: Forty patients with chronic dizziness and without any vertigo spell for least 6 months prior to testing. In all of them, a unilateral vestibulopathy was diagnosed clinically and at vestibular testing...

Vision impairments such as age-related macular degeneration (AMD) and glaucoma are among the top risk factors for geriatric falls and falls-related injuries. AMD and glaucoma lead to loss of the central and peripheral visual fields, respectively. This study utilized a custom contact lens model to occlude the peripheral or central visual fields in healthy adults, offering a novel within-subject approach to improve our understanding of the etiology of balance impairments that may lead to an increased fall risk in patients with visual field loss...

Individuals with chronic obstructive pulmonary disease (COPD) have demonstrated balance impairment and a higher fall incidence. However, these have not been investigated in acute exacerbations of the disease (ECOPD). This study evaluates balance in patients during an ECOPD compared to stable COPD and healthy controls, and examines the fall incidence rate after hospitalisation due to ECOPD compared to individuals with stable COPD. Balance performance of 26 hospitalised patients with ECOPD was compared to 26 community-dwelling participants with stable COPD and 25 matched healthy controls...

PURPOSE: Many patients participating in cardiac rehabilitation (CR) programs have decreased balance. This is a concern, as it may affect their ability to optimally perform physical exercise in CR and thus decrease CR efficacy. Despite this concern, balance is typically not assessed as part of CR intake. This may be attributable to the fact that a suitable balance assessment tool has not been identified for higher-functioning CR patients. A potential solution to this issue is using the Community Balance and Mobility Scale (CBMS), which has been used to assess balance in higher-functioning clinical populations; however, its use in a CR population has never been investigated...

Top sports performances cannot be achieved without a high level of postural control. Balance wristbands purport to improve the mental and physical balance of the wearer. It is still unclear, however, whether these wristbands can indeed enhance postural control. Our purpose was to ascertain by means of computerized dynamic posturography whether balance wristbands can improve postural stability.In this randomized controlled single-blind clinical study, posturography was used to assess postural control in 179 healthy subjects with or without a balance wristband...
