AIM: To study gait disorders and postural instability in patients with essential tremor (ET). MATERIAL AND METHODS: Forty patients with ET, aged from 29 to 82 years, (mean 64.2±13.0) were examined. Tandem walk, tremor, stability and stabilometry were studied. RESULTS AND CONCLUSION: A half of the patients had gait disorders and postural instability. Though these disorders were mild to moderate, they caused significant subjective discomfort and influenced quality of life...

DEFINITION OF THE DISEASE: Ataxia telangiectasia (A-T) is an autosomal recessive disorder primarily characterized by cerebellar degeneration, telangiectasia, immunodeficiency, cancer susceptibility and radiation sensitivity. A-T is often referred to as a genome instability or DNA damage response syndrome. EPIDEMIOLOGY: The world-wide prevalence of A-T is estimated to be between 1 in 40,000 and 1 in 100,000 live births. CLINICAL DESCRIPTION: A-T is a complex disorder with substantial variability in the severity of features between affected individuals, and at different ages...

INTRODUCTION: Postural instability/gait difficulty (PIGD) and fear of falling (FoF) frequently co-exist, but their individual predictive values for falls have not been compared in aging. This study aims to determine both independent and combined effect of PIGD and FoF to falls in older adults without dementia. METHODS: PIGD and other extrapyramidal signs were systematically assessed in 449 community-dwelling participants without Parkinson's disease (76.48±6.61 ys; 56...

About forty certified patients aged around 50 years old existed as living witnesses to fetal-type Minamata disease (methylmercury poisoning due to in utero exposure) in Minamata, Japan in 2006. Computerized hand tremor and postural sway tests with spectral analysis were conducted for 24 of them and in matched control subjects to examine the pathophysiological feature of neuromotor function. The tremor intensities of the patients with fetal-type Minamata disease were significantly larger than those of the 67 controls at every frequency band for both hands...

BACKGROUND: This study assessed: 1) the effects of 12 weeks of resistance training (RT) and resistance training with instability (RTI) on presynaptic inhibition (PSI) and disynaptic reciprocal inhibition (DRI) of patients with Parkinson's disease (PD); 2) the effectiveness of RT and RTI in moving PSI and DRI values of patients towards values of age-matched healthy controls (HC [Z-score analysis]); and 3) associations between PSI and DRI changes and clinical outcomes changes previously published...

BACKGROUND: Case reports are presented on four Veterans, aged 29-46 years, who complained of chronic dizziness and/or postural instability following blast exposures. Two of the four individuals were diagnosed with mild traumatic brain injury and three of the four were exposed to multiple blasts. Comprehensive vestibular, balance, gait, audiometry and neuroimaging procedures were used to characterize their injuries. CASE REPORT: Vestibular assessment included videonystagmography, rotary chair and cervical and ocular vestibular evoked myogenic potentials...

Balance and cognition are affected by multiple sclerosis (MS). Cognitive-motor interference (CMI) is important for balance impairment in MS, however little is known about CMI at the earliest stages of the disease. Step initiation (SI) with anticipatory postural adjustments (APAs) has been linked to postural instability and falls in subjects with MS, therefore we aimed to assess CMI between SI and the two storage systems of working memory in patients with clinically isolated syndrome (presented as optic neuritis-ON) suggestive of MS...

Postural control deficits have been suggested to be a major component of gait disorders in children with cerebral palsy. The purpose of this study was to investigate the relationship between postural stability and treadmill walking, in children with unilateral cerebral palsy, by defining dependence between the posturographic weight-bearing distribution and center of pressure (CoP) sway during quiet standing with Gillette Gait Index and the 16 distinct gait parameters that composed the Gillette Gait Index. Forty-five children with unilateral cerebral palsy from 7-12 years of age were included in this study...

INTRODUCTION: Oxidative stress, alpha-synuclein changes, mitochondrial complex I defects and dopamine loss, observed in the striatum of rats exposed to the pesticide permethrin in early life, could represent neuropathological hallmarks of Parkinson's disease (PD). Nevertheless, an animal model of PD should also fulfill criteria of face and predictive validities. This study was designed to: 1) verify dopaminergic status in the striatum and substantia nigra pars compacta; 2) recognize non-motor symptoms; 3) investigate the time-course development of motor disabilities; 4) assess L-Dopa effectiveness on motor symptoms in rats previously exposed to permethrin in early life...

OBJECTIVE: The aim of this study is to determine characteristics of non-motor symptoms (NMS) in early Parkinson's disease (PD) with olfactory deficits and to analyze the feasibility of diagnosing PD based on olfactory deficits. PATIENTS AND METHODS: 62 patients without olfactory deficits in early PD (PD group), 58 patients with olfactory deficits in early PD (olfactory deficits group) and 60 healthy examined people (control group) were selected successively. RESULTS: It was found that there was no statistical significance in the difference in ages and courses of disease among the three groups (p > 0...

OBJECTIVE: Weight-bearing asymmetry (WBA) at the expense of the paretic side concerns 60% of stroke patients. WBA is associated with poor functional prognosis especially in terms of gait performance [1,2]. The primary objective was to assess the determinants of WBA in stroke patients from clinical and instrumental data. MATERIAL/PATIENTS AND METHODS: The sensitivity (EmNSA), motricity (Fugl-Meyer motor), spatial neglect and visual perception of verticality (VPV) were evaluated in 20 stroke patients (age: 53...

OBJECTIVE: To determine the effect of completing a vestibular rehabilitation treatment protocol on postural balance, dizziness and quality of life in patients with peripheral vertigo. MATERIAL/PATIENTS AND METHODS: A prospective study concerning patients with instability due to unilateral peripheral vestibular disorder. The patients were evaluated with a clinical examination and a test of static and dynamic balance on the Satel(®) platform in which length, mediolateral (LongX) and anterior-posterior deviations (long Y) were monitored...

OBJECTIVE: Distal sensorimotor polyneuropathy (DPN) is a leading risk factor of developing ulcer, including increased pressures at the forefoot. The rocker sole shoes are prescribed to decrease pressures but could induce instability [1]. The aim of this study was to compare the postural stability between normal shoes (NS) and rocker sole shoes (RSS) in patients with type 2 diabetes and DPN. MATERIAL/PATIENTS AND METHODS: In this preliminary, randomized, controlled study, NS and RSS were compared during static standing and gait...

Background. Changes in proprioception may contribute to postural instability in individuals with neurological disorders. Objectives. Evaluate proprioception in the lower limbs of patients with Parkinson's disease (PD) and the association between proprioception and cognitive ability, motor symptoms, postural instability, and disease severity. Methods. This is a cross-sectional, controlled study that evaluated proprioception in PD patients and healthy age- and sex-matched individuals. Kinetic postural proprioception of the knee was evaluated using an isokinetic dynamometer (Biodex® Multi-Joint System 4 Pro)...

CONTEXT: Both balance training and selected interventions meant to target sensory structures (STARS) have been shown to be effective at restoring deficits associated with chronic ankle instability (CAI). Clinicians often utilize multiple treatment modalities in patients with CAI. However, evidence for combined intervention effectiveness in CAI patients remains limited. OBJECTIVE: To determine if augmenting a balance training protocol with STARS (BTS) results in greater improvements than balance training (BT) alone in those with CAI...

CONTEXT: Individuals with chronic ankle instability (CAI) present with decreased modulation of the Hoffmann reflex (H-reflex) from a simple to a more challenging task. The neural alteration is associated with impaired postural control, but the relationship has not been investigated in individuals with CAI. OBJECTIVE: To determine differences in H-reflex modulation and postural control between individuals with or without CAI and to identify if they are correlated in individuals with CAI...
