Cíl: Montrealský kognitivní test (MoCA) je jednou z nejpoužívanějších screeningových zkoušek kognice u dospělých osob, pro něž existují normy pro českou populaci. Varianta MoCA-22, která je určena pro osoby s poruchami zraku či imobilitou horních končetin, se dá administrovat i po telefonu. Tato studie přináší české normy MoCA-22. Materiál a metodika: Soubor (n = 1 049) se skládá z účastníků čtyř studií provedených v ČR. Zařazeny byly osoby ve věku 19–98 let, bez neurodegenerativního, psychiatrického či jiného závažného onemocnění. Data pro MoCA-22 byla odvozena z dat získaných vyšetřením standardní verzí MoCA. V souladu se zavedenou klinickou praxí i statistickou analýzou jsou soubor a odvozené normy rozděleny na tři věkové kategorie: 19–50 let, 51–74 let, 75 a více let. Výsledky: Pro výše uvedené věkové kategorie dále rozdělené dle dosaženého vzdělání (nižší, vyšší) předkládáme průměrné skóry i odhadované percentilové hranice. Výkon v MoCA-22 je ovlivněn dosaženým vzděláním a věkem, ale nikoli pohlavím. Pro úpravu výsledků dle demografických faktorů proto poskytujeme i regresní rovnici. Závěr: Normativní údaje pro MoCA-22 rozšíří klinické instrumentárium v Česku a umožní adekvátní screening kognice u osob, jež jsou zdravotním stavem limitovány při využití standardních metod.
Aim: The Montreal Cognitive Assessment (MoCA) is one of the most widely used cognitive screening tests in adults with reference standards for the Czech population. The MoCA-22 variant is designed for individuals with visual impairment or upper limb immobility and can be administered over the telephone. This study presents the Czech MoCA-22 normative standards. Materials and methods: The sample (N = 1,049) consists of participants from four studies conducted in the Czech Republic. The subjects included were aged 19–98 years, and were without neurodegenerative, psychiatric, or other serious illness. Data for the MoCA-22 were derived from data obtained by the standard version of MoCA. Following established clinical practice and statistical analysis, the population and derived norms are divided into three age categories: 19–50 years, 51–74 years, and 75 years and older. Results: For these age categories above, which were further subdivided by educational status (lower, higher), we present mean scores and estimated percentile thresholds. Performance in the MoCA-22 is affected by demoraphic factors, such as educational status and age but not sex, as reflected by the regression equation. Conclusions: Normative data for MoCA-22 will complement the clinical armamentarium in Czechia and allow adequate cognitive screening in people whose health status limits them when using standard methods.

Cíl: Představit historii a současnost zrakových korových neuroprotéz a předložit novou metodu stimulace nepoškozených buněk zrakové kůry. Metody: Práce podává nejen přehled o historii a současném stavu stimulace zrakové kůry u těžkých poruch zraku, ale hlavně upozorňuje na jejich nedostatky. K nim se řadí hlavně stimulace právě poškozených korových buněk na malé ploše a z morfologického hlediska pak možné poškození stimulovaných neuronů elektrodami a jejich zapouzdření gliotickou tkání. Výsledky: Práce dále předkládá návrh nové technologie zpracování obrazu a jeho transformace do podoby neinvazivní transkraniální stimulace nepoškozených částí mozku, která je chráněna národním i mezinárodním patentem. Závěr: V práci je předložen ucelený přehled současných možností náhrady ztraceného zraku na úrovni mozkové kůry a návrh nové neinvazivní metody stimulace funkčních neuronů zrakové kůry.
Purpose: The purpose of the article is to present the history and current status of visual cortical neuroprostheses, and to present a new method of stimulating intact visual cortex cells. Methods: This paper contains an overview of the history and current status of visual cortex stimulation in severe visual impairment, but also highlights its shortcomings. These include mainly the stimulation of currently damaged cortical cells over a small area and, from a morphological point of view, possible damage to the stimulated neurons by the electrodes and their encapsulation by gliotic tissue. Results: The paper also presents a proposal for a new technology of image processing and its transformation into a form of non-invasive transcranial stimulation of undamaged parts of the brain, which is protected by a national and international patent. Conclusion: The paper presents a comprehensive review of the current options for compensating for lost vision at the level of the cerebral cortex and a proposal for a new non-invasive method of stimulating the functional neurons of the visual cortex.

Background: Nutrition an integral part of child growth and development.Aim: Comparison regarding mothers' knowledge and practice between blind and non-blind child.Patients and Methods: A case control study design of 120 mothers (40 mother of blind child and 80 mother of non-blind child). It was adopted in UmAl-Rbean Development Foundation for Blind and purblind during.Results: revealed that 108 (90%) agree that with food we can control most of our disease. Diet-disease relationship reported by mothers were obesity 92 (77%) and hypertension 66 (55%) with P-value 0.017. Mothers' knowledge regarded true fact (playing sport and eat and drink, and do not be extravagant were 120 (100%) and 76 (63.3%) respectively. Mothers reported that 72 (60%) of study sample eat protein twice a day, 92 (76.7%) eat carb frequently aday, 54 (45%) eat fat once a day, 68 (56.7%) eat fruit and vegetable twice a day. Drinking plenty of water seen among blind child 18 (45%) while drinking of water with meal seen among non-blind 66 (82.5%). Drinking of tea commonly among non-blind 72 (90%) and specially with meal 28 (38.9%).Conclusion: The study concluded that mothers of non-blind children more knowledgeable than mothers of blind children. Eating carb and fat twice a day commonly seen among blind child mean while eating protein and fruit and vegetable twice a day more prevalent among non- blind child.Recommendation: Exclusive education program to mother of blind child to improve their knowledge and enhance health practice toward their child nutrition.

This study evaluated the influence of acute fatigue on shooting skill performance in goalball penalty shots. Eleven sub-elite male players were evaluated in an official court using a two-dimensional procedure (60 Hz) to compute the mean radial error, bivariate variable error and accuracy, and three-dimensional kinematics (240 Hz) to measure ball velocity. Rating of perceived exertion, blood lactate concentration and knee extension isometric maximal voluntary contractions were assessed at rest and immediately after the completion of an incremental test specific to goalball. Although significant differences were observed for rating of perceived exertion (pre: M = .36 AU, SD = .67; post: M = 9.27 AU, SD = .79), blood lactate concentration (M = 1.33 mM, SD = .51; M = 9.04 mM, SD = 2.25) and peak force (M = 597.85 N, SD = 132.35; M = 513.37 N, SD =107.00) at the end of the incremental test, no differences were identified in the pre and post moments for mean radial error (M = .10 m, SD = 1.01; M =.37 m, SD = 2.19), bivariate variable error (M = 3.56 m, SD = .70; M = 3.25 m, SD = .70), accuracy (M = 3.68 m, SD = .74; M = 3.78 m, SD = 1.13) and ball velocity (M = 18.53 m.s-1, SD = 1.53; M =18.46 m.s-1, SD = 1.65). We concluded that even though significant levels of fatigability can be attributed to the incremental test specific to goalball, shooting skill performance in goalball penalty shots does not appear to be affected. However, further investigations are needed so that goalball coaches can develop strategies that contribute to improve performance in this technical action. Such improvements are decisive for the outcome of a match.

Football (soccer) is one of the most popular sports for individuals with visual impairments (VI) worldwide but nascent within the United States (US). While there is burgeoning interest toward developing blind football at grassroot and national levels, particularly with the forthcoming 2028 Paralympics, no football-based talent identification or skill assessment has been developed or vetted in the US. Therefore, the purpose of this study was to investigate the immediate measurement properties of scores from a novel football assessment in amateur-skilled adolescents with VI in the US. Adolescents (n = 57) with VI physically completed the Blind Football Skills Test for Adolescents with VI (BFST-AVI) which was comprised of five football-related tasks. Scores were analyzed by item analyses, internal consistency, convergent validity, and construct validity procedures. The results suggested that total and individual assessment scores had acceptable levels of reliability and validity. The BFST-AVI can be adopted immediately by grassroot organizations, national governing bodies, coaches, adapted and general physical educators, and associated practitioners for talent identification or general motor skill assessment purposes for amateur-skilled adolescents with VI.
