Filter by:Virtual reality (VR) is a three-dimensional image, which is created by means of computer programs. In most educational communities VR has been used as an opportunity to support many students. VR allows the user to observe the world generated for their own needs as the real world and experience impressions that are not available in real life. It was decided to examine how immersive VR-game will affect the eye-hand coordination on music school students. The experimental group received a five-day training sessions using immersive VR game "Beat Saber", while control group was inactive comparator.
Friedreich's ataxia is a debilitating, inherited disease cause by mutations in a protein called frataxin (FXN). FXN is one of several proteins that controls the production of iron-sulfur clusters, molecules that are essential for energy production in our cells as well as repair of our genetic code embedded in DNA molecules. Friedreich's ataxia (FRDA) and deficiency of FXN results in a nerve disease affecting coordination and a condition called hypertrophic cardiomyopathy (HCM), marked by an abnormal thickening of the heart. Patients with HCM can then develop pulmonary hypertension (PH), a deadly condition of the blood vessels of the lung. While most of the research in FRDA has focused on nerves and heart muscle, alterations in blood vessels of the heart and lung may worsen disease in FRDA. But, the role of FXN in these blood vessels has never been defined. Investigators pilot data suggest that Frataxin (FXN ) deficiency can control senescence and downstream function in various types of Endothelial cells (ECs), investigators hypothesize that Friedreich's Ataxia (FRDA) patients may demonstrate endothelial cells EC abnormalities throughout the vasculature potentially before overt cardiomyopathy develops.
Combining cognitive training with physical training to improve balance is a new approach for reducing the risk of falls in patient populations who are at risk for falls. People with brain pathology including cerebellar ataxia (CA) have difficulty in performing dual-tasks. Deficiency in dual-task performance relative to single-task performance referred to as dual-task cost is high in CA. Due to the high demands on cognitive resources, people with CA have higher falls rates during activities that involve dual tasking. Tai-Chi involves both cognition and physical movements making it a dual-tasking activity. However, previous study on the effects of 12-weeks of 8-form Tai-Chi did not demonstrate that it had beneficial effects in reducing falls among CA population. This null finding could potentially be due to (1) the lower levels of cognitive demands of Tai-Chi exercise, (2) the intervention not being intensive enough, or (3) the intervention may not have targeted the specific symptoms of CA. To determine if adding structured cognitive demands to conventional balance and coordination training (i.e., addressing all three possibilities for our previous null findings), the investigaotrs conducted a pilot study (n=5) to evaluate the feasibility, safety and benefits of a Cognitive-coupled Intensive Balance Training (CIBT) program. The more intensive and focused CIBT intervention reduced dual-task cost, improved balance, and reduced the number of falls in a sample of individuals with CA. Important next steps is to (1) evaluate the efficacy of the CIBT in a fully powered clinical trial, (2) understand the mechanisms underlying the benefits of CIBT training, and (3) determine the cost-benefits of this intervention. The hypothesis for the study includes (1) CIBT will improve balance and reduce falls; (2) reduction in dual-task cost of balance and cognitive performance will mediate a reduction in the number of falls in CA and (3) CIBT will be a cost-effective treatment option for improving balance and reduce falls. To test these hypotheses, a randomized controlled trial (RCT) with economic evaluation will be conducted over a period of two years to evaluate the effectiveness and cost-effectiveness of dual-task (CIBT) training compared with single-task (conventional balance: active control) training in individuals with CA.
Friedreich Ataxia (FA) is a hereditary neurological disease that is associated with a cerebellar syndrome and pyramidal symptoms. Clinical expression varies from one individual to another and throughout the evolution of the disease and is partially related to an abnormal expansion of the GAA triplet repeat in the frataxin gene. Dysarthria, a disorder in the motor production of speech, is always present in the clinical presentation of the disease (Schöls et al. 1997 ; Harding 1981 ; Dürr et al. 1996 ; Delatycki et al. 1999). It has been the subject of specific studies exploring the link between the evolution of dysarthria and disease progression (J. Folker et al. 2010; J. E. Folker et al. 2012; Rosen et al. 2012; Brendel et al. 2013). These studies allowed for the identification of markers for speech disintegration, specific to FA dysarthria, using perceptive voice measures, but also acoustics and objectives for qualifying voice and speech at the same time. The challenge is in finding measures sufficiently appropriate and sensitive to detect the evolution of these indicators throughout the course of the disease (Rosen et al. 2012). The neurological scales that take in to account all signs of a cerebellar syndrome are not sufficiently sensitive (Marelli et al. 2012). In addition, hearing difficulties develop during the course of the disease in addition to visual disturbances (gaze instability) which hinder communication. The ORFA study aims to evaluate oral communication in FA patients and identify appropriate measures that allow for the comparison of dysarthria pre and post-treatment in a clinical trial and can be used for the evaluation of efficacy.
Ataxia telangiectasia (A-T) is a rare autosomal recessive neurodegenerative disorder characterized by progressive cerebellar ataxia, immunodeficiency, chromosomal instability, and cancer susceptibility. Currently there are no curative therapy options. The clinical presentation of the disease has a wide variety is linked to the proven mutation, immunological status and residual ATM kinase activity. Apart from these prognostic markers, hardly any biomarker to predict disease course is available. Aim of the present proposal is to evaluate serum concentrations of neurofilament - light chain in the serum of whole blood as biomarker of neurodegeneration prospectively. In addition to that, the investigators will examine the evolution of neurofilament - light chain longitudinally by blood samples from our biobank as well as the concentration of neurofilament - light chain in cerebrospinal fluid (CSF) of affected A-T patients from our biobank. As in other neurodegenerative disorders and ataxias, the investigators expect that neurofilament- light chain levels are increased in the A-T cohort and correlated to the neurological status of A-T patients evaluated by means of AT-score.
The present study investigated the efficacy and safety of combination treatment of repetitive transcranial magnetic stimulation (rTMS) and physical therapy (PT) in patients with cerebellar variant of multiple system atrophy (MSA-C) and spinocerebellar ataxia.
The primary objective of the study is to evaluate the efficacy (using the modified Friedreich Ataxia Rating Scale [mFARS]) and safety of vatiquinone in participants with Friedreich ataxia (FA).
