Quantitative Evaluation of Stance as a Sensitive Biomarker of Postural Ataxia Development in Preclinical SCA1 Mutation Carriers.

The aim of this study was to determine the time between the first detection of postural control impairments and the evident manifestation of ataxia in preclinical SCA1 individuals. Twenty five preclinical SCA1 mutation carriers: 13 with estimated disease onset ≤ 6 years (SCA1 +) aged 27.8 ± 8.

Is Balance Training Using Biofeedback Effective in the Prophylaxis of Falls in Women over the Age of 65?

The paper aims to investigate the usefulness of training in improving mobility and reducing the risk of falls of patients with osteoarthritis by using a force plate and virtual reality as rehabilitation tools. The study involved 72 women randomly divided into two equal groups: the force plate training group, which underwent virtual balance training with visual motor feedback, and the gym training group, which received conventional balance training only. The functional balance assessment was performed before and after the rehabilitation by computerized posturography in a relaxed upright position with open and closed eyes, with visual motor feedback.

Estimation of Posturographic Trajectory Using k-Nearest Neighbors Classifier in Patients with Rheumatoid Arthritis and Osteoarthritis.

Rheumatoid arthritis (RA) and osteoarthritis (OA) are common rheumatic diseases and account for a significant percentage of disability. Posturography is a method that assesses postural stability and quantitatively evaluates postural sways. The objective of this study was to estimate posturographic trajectories applying pattern recognition algorithms.

Discriminant Analysis of Intracranial Volumetric Variables in Patients with Normal Pressure Hydrocephalus and Brain Atrophy.

A method was developed for the computerized volumetric assessment of the intracranial cerebrospinal fluid (CSF) distribution. The study involved 62 patients differentiated into two groups: with CSF resorption disorders (normal pressure hydrocephalus - 30 patients) and without CSF resorption disorders (various types of brain atrophy - 32 patients). The goal of the study was to ascertain whether the assessment, depending on the linear discriminant analysis of volumetric brain features, could be an effective tool differentiating the two groups.

Analysis of intracranial volume ratios by means of cerebrospinal fluid deployment indicators.

Introduction: Imaging studies make it possible not only to visualize the general structure of the brain but also to take precise measurements of brain tissue volume and the size of individual lobes and their structure. The aim of this study was to determine the ratio of cerebrospinal fluid (CSF) volume contained in the intracranial ventricular system to the brain tissue volume and the ratio of CSF volume in the subarachnoid space and basal cisterns to the brain tissue volume.

Material And Methods: The evaluation of volumetric measurements of computed tomographic (CT) images was undertaken on 23 male and female patients (average age 56.

[The usefulness of the evaluation of volumetric and posturographic parameters in the differential diagnosis of hydrocephalus].

Introduction: A variety of diagnostic methods in normal pressure hydrocephalus and brain atrophy, it testifies to the difficulties in contrast to both teams. Develop a safe diagnostic tool having comparable statistical accuracy of the infusion test results would be of great clinical significance. The chances of implementing such a procedure in clinical practice, it may be a combination of these syndromes in the functional assessment (Posturography) the assessment of morphological CNS (volumetric).

[Diffusion tensor imaging (DTI) in the differential diagnosis of normal pressure hydrocephalus and brain atrophy].

Unlabelled: Clinical symptomatology of idiopathic normal pressure hydrocephalus, due to its overlap with dementias and neurodegenerative brain disorders, makes diagnosis challenging. As the neurological deficits are reversible there is a need for prompt and reliable noninvasive testing. The aim was to try to use and introduction into clinical practice of new non-invasive method--diffusion tensor imaging (DTI-Diffusion Tensor Imaging) discriminating patients classified as normal pressure hydrocephalus and patients diagnosed with brain atrophy.

Posturography in differential diagnosis of patients with enlargement of brain ventricles.

Background And Purpose: This study aimed to quantitatively evaluate balance disturbances by means of static posturography in patients with enlargement of the ventricular system (Evans ratio > 0.3).

Material And Methods: Fifty-four patients were diagnosed and treated in our Department of Neurosurgery.

Posturography in differential diagnosis of normal pressure hydrocephalus and brain atrophy.

Differentiation between normal pressure hydrocephalus (NPH) and brain atrophy is difficult in clinical practice. The purpose of this paper was to apply two advanced statistical, pattern recognition methods: discriminant analysis (DA) and k-nearest neighbour (K-NN) for the classification of NPH and atrophy patients to approach computer aided differential diagnosis. The classification is based on a few measures of the center of foot pressure (COP) movements (radius, area, and length).

[Posturography and computerized gait analysis in the Computer Dyno Graphy system as non-invasive methods for evaluation of normal pressure hydrocephalus progression].

Disturbances of gait and balance are important clinical problems in patients with normal pressure hydrocephalus. A considerable degree of locomotor disability and increased risk of falls are present in many cases. Accordingly, attempts to develop effective evaluation methods of gait and balance disturbances are made.

Low serum triiodothyronine in acute myocardial infarction indicates major heart injury.

Aims: In patients with acute myocardial infarction (MI), low serum triiodothyronine (T3) concentration is commonly associated with a severe clinical course. The aim of this prospective study was to investigate whether a severe clinical course in patients with low T3 is related to the magnitude of myocardial injury assessed by echocardiography.

Methods And Results: Out of 635 patients with MI we enrolled 100 consecutive patients.
