Children with developmental coordination disorder (DCD) find academic and performing age-appropriate perceptual-motor skills more difficult than their peers. According to research, children classified as learning disabled often show signs of one or more syndromes of developmental disorders rather than an isolated, discrete disability. The more common learning disorders include disabilities related to verbal communication development, reading disorders, gross and fine motor dysfunction and motor hyperactivity. Attention disorders, including or excluding hyperactivity, are not considered learning disabilities in themselves. However, because attention problems can gravely interfere with school performance, they are often associated with problems concerning academic skills Literature further reveals that boys are more inclined to motor problems, learning disabilities and ADHD, compared to girls. With regards to racial diversity, limited information is available, even though some literature implies that certain racial diversities differ to some extent regarding motor problems (DCD). The purpose of this study was to examine the relationship between DCD, learning disabilities and ADHD of children (N = 99) in the age group 6 to 7 years in Potchefstroom in the NW province. A second purpose was to examine the differences between gender and certain racial groups in the age group 6 to 7years in Potchefstroom with regards to to DCD, learning disabilities and ADHD. Two grade one classes were randomly selected from three selected schools in the Potchefstroom district proportionally representing the different racial groups [white (n = 37), black (n = 50), Coloured (n = 12)]. In this group, 48 boys and 53 girls were evaluated with the Movement ABC (MABC) (Henderson & Sugden, 1992), the Aptitude test for school beginners (ASB) (Swart et a/., 1994), the Modified Conner's abbreviated teacher and the Taylor Hyperactivity checklist (Lowenberg & Lucas, 1999). The Statistics for Windows computer package was used for analyzing the data. The group of children without DCD showed a statistically significant higher total ASB scores than the DCD group (p ≤ 0.00). A multiple regression analysis showed a statistically significant interaction between DCD, learning disabilities and ADHD which varied between 22% and 36%. Analysis of differences in the ASB of boys and girls with and without DCD showed no significant interactions, although racial interactions (p < 0.001) were found with the DCD group (p < 0.025). Boys with DCD did not perform as well as the girls in the coordination subtest, and their ADHD totals indicate more symptoms than those of the girls. Black children's numerical skills, verbal communication and the ASB total appeared to be considerably lower than the values of the white children. Overall, the conclusion can be made that DCD has an effect on 6 to 7-year old children's learning abilities and to a lesser extent on their ADHD status. / Thesis (M.A. (Human Movement Science))--North-West University, Potchefstroom Campus, 2007.

Este estudo investigou o desenvolvimento e a influência dos ajustes posturais antecipatórios na performance de um movimento direcionado a um alvo em crianças com e sem DCD. Os participantes foram divididos de acordo com três faixas etárias [faixa etária (A) de 7-8 anos (média de 7.6 anos ± 0.6 ); faixa etária (B) de 9-10 anos (média de 9.7 anos ± 0.7); faixa etária (C) de 11-12 anos (média de 11.7 anos ± 0.5). Cada grupo foi formado por crianças com DCD e crianças de desenvolvimento típico. As com DCD foram identificadas através de um percentil igual ou inferior a 5 no Teste Movement ABC. As crianças com desenvolvimento típico foram identificadas como aquelas cujo escore apresentou-se igual ou superior a 30. As crianças foram orientadas a permanecer na posição em pé e executar um movimento direcionado a um alvo. Variáveis de tempo de reação, tempo de movimento e a amplitude dos ajustes posturais antecipatórios foram examinadas em função da idade. Os resultados indicaram que as crianças com DCD foram significativamente mais lentas que as crianças com desenvolvimento típico durante a iniciação e execução do movimento direcionado a um alvo e também apresentaram um maior deslocamento lateral do centro de pressão. A análise desenvolvimental mostrou que, à medida que a criança cresce, aumenta a estabilidade postural na direção lateral e reduz os tempos de reação e movimento. Porém, crianças com DCD não alcançaram o mesmo nível de performance em comparação as crianças de desenvolvimento típico. Quando atrasos hipotéticos de idade foram calculados a partir das equações da análise de regressão, as crianças mais velhas do grupo DCD mostraram aumento destes atrasos nos ajustes posturais e diminuição destes no tempo de reação e movimento. Estes resultados dão suporte à hipótese de que os ajustes posturais antecipatórios interferem na performance do movimento. / This study investigated the development and influences of anticipatory postural adjustments on the performance of a goal-directed movement in children with and without DCD. Participants were placed into one of three age bands [age band (A) with 7 and 8 years (mean age 7.6 years ± 0.6; age band (B) with 9 and 10 (mean age 9.7 ± 0.7); age band (C) with 11 and 12 years (mean age 11.7 ± 0.5)]. Each group consisted of children with DCD and typically developing children. Children with DCD were defined as those with scores at or below the 5thpercentile on Movement ABC Test. Typically developing children were those whose scores on the test were above the 30th percentile. The children were asked to stand in right position and perform a goal-directed movement. Reaction time, movement time and amplitude of postural adjustments were examined as a function of age. Results indicated that children with DCD were significantly slower than typically developing children during the initiation and execution of the goal-directed movement and also showed a larger lateral displacement of the center of pressure. Developmental analysis showed that, as children grow up, they increase their postural stability in lateral direction and decrease their reaction and movement time. However, children with DCD do not reach the same level of performance as compared to typically developing children. When hypothetical age delays were calculated by the equations in the regression analysis, older children in the DCD group showed increasing age delays of the postural adjustments but decreasing age delays in reaction and movement time. These results support the hypothesis that anticipatory adjustments interfere in movement performance.

Denna studie handlar om en för många okänd diagnos vid namn Developmental CoordinationDisorder (DCD) eller i svenska uttryckt motorisk koordinationsstörning. Syftet är att undersökakunskapsläget kring DCD bland lärare i idrott och hälsa och specialpedagoger samt beskriva arbetetför att skapa en tillgänglig lärmiljö i ämnet idrott och hälsa för dessa elever. Den teoretiskautgångspunkten bottnar i den humanekologiska teoribildningen och närmare bestämt i en modell vidnamn M.A.T.C.H vilken utformats för att i skolan kunna bedriva ett främjande arbete för elever medDCD. M.A.T.C.H fungerar även som ett analysverktyg i tolkningen av empirin. Studien är avkvantitativ och kvalitativ karaktär och metoden som användes för datainsamling är enkät. Enkätenbesvarades av 56 lärare i idrott och hälsa och 60 specialpedagoger. Resultaten visar att knappt hälftenav respondenterna har hört talas om DCD och att 25 % eller färre anser att de har kunskap kring hurDCD påverkar ett barns motorik. Gällande kunskap kring hur undervisningen kan anpassas efter elevermed DCD anser knappt hälften av lärarna och färre än 10 % av specialpedagogerna att de har detta.Vidare visar studien att de flesta lärare gör anpassningar för dessa elever och att dessa framförallthandlar om nivåanpassningar. Gällande specialpedagogernas delaktighet i anpassningarna uppger färreän hälften att de bidragit i detta arbete. Resultatet visar också att färre än hälften av lärarna väljer attkontakta en specialpedagog för handledning i arbetet. Orsakerna till varför många inte gör detförklarar de med att specialpedagogerna ofta har brist på kunskap och tid. Knappt hälften avspecialpedagogerna uppger att de ger handledning till lärarna och beskriver bland annat att det krävsbättre organisatoriska förutsättningar. I resultatdiskussionen förs ett resonemang kring hur ökadkunskap och samverkan kan bidra till att utveckla arbetet för att möta elever med DCD. Slutsatsernaformuleras i begreppen kunskap och samverkan. En ökad kunskap kring DCD samt en närmresamverkan mellan lärare i idrott och hälsa och specialpedagoger kan fördjupa det arbete som redangörs gällande anpassningar samt främja en tidig upptäckt av elever med DCD.

Projektet hade som syfte att hjälpa personer med diagnosen dyspraxi, mer specifikt oral dyspraxi. Oral dyspraxi yttrar sig som problematik medatt koordinera munrörelser vilket kan leda till svårigheter att prata tydligt och därmed även saker som svårigheter att kommunicera med andra och talgenans. Dyspraxi yttrar sig som tydligast hos unga barn då dessa ännu inte hunnit utveckla metoder för att dölja sin funktionsnedsättning. I projektet uppstod idén att denna problematik kunde hjälpas genom att skapa motivation och glädje i talpedagogiksessioner som annars kan kännas som utdragna för det barn som genomgår dem. Denna tanke ledde till efterforskning kring gamification och resulterade i ett brädspel som används av barnet med dyspraxi ihop med en talpedagog baserat på talpedagogikmetoden Rapid Syllable Transition Treatment. Brädspelet ficknamnet svammel utifrån de nonsensord som förekommer inom RapidSyllable Transition Treatment.

The aim of this thesis is to evaluate the level of motor skills in children and adolescents dealing with judo and taekwondo and to determine whether the level of motor skills differs between children with a suspected risk of ADHD (Attention Deficit Hyperactivity Disorder) compared to children without this risk. Another aim of this study is to evaluate the level of attention and find out whether it correlates with the level of motor skills. A total of 65 probands aged 9-13 years participated in the study. The experimental groups consisted of children competing in judo (n = 35), children practicing taekwondo (n = 19) and children attending taekwondo classes in physical education and hobby groups (n = 11). The Movement Assessment Battery for Children 2 test was chosen to test motor skills. To detect a suspected risk of ADHD was used the Test Go / NoGo and the level of attention was tested by theTest of attention d2. A significant difference in favour of judists was found between the results of motor skills of children and adolescents in comparison with the racing group of taekwondists (p = 0.045) and also in the results of individual components, namely in the balance component (p = 0.051). A significant difference was found in motor skills among children with a suspected risk of ADHD compared to...

Il est prouvé que la conservation des greffons rénaux marginaux en machine de perfusion (MP) est bénéfique. Cependant, cette méthode nécessite des améliorations afin de minimiser les lésions d’ischémie-reperfusion (I/R), par l’ajout d’oxygène et/ou d’un transporteur d’oxygène. Nous avons cherché à évaluer les effets de l’oxygénation et de l’ajout d’une hémoglobine de ver marin (HbAm, M101) durant la perfusion rénale hypothermique avant transplantation. Nos critères de jugement étaient basés sur la reprise de fonction du greffon et sur les lésions tardives de dysfonction rénale. Nous avons utilisé un modèle porcin : les reins ont été exposés à 1h d’ischémie chaude, puis perfusés dans une MP WAVES® pendant 23h à 4°C avant autotransplantation. Quatre groupes ont étudié : W (MP-21% O2), W-O2 (MP-100% O2), W-M101 (MP-21% O2 + 2g/L HbAm), W-O2+M101 (100% O2 + 2g/L HbAm), (n=6 per groupe). Les reins du groupe W-M101 ont montré un débit de perfusion plus élevé et une résistance rénale plus faible comparé aux autres groupes. Pendant la première semaine post-transplantation, les groupes W-O2 et W-M101 ont montré une créatininémie significativement plus faible et un meilleur taux de filtration glomérulaire (GFR). Les niveaux circulants de KIM-1 et IL-18 étaient plus faibles dans le groupe W-M101, tandis que les niveaux de NGAL et d’ASAT étaient plus faibles dans les groupes d’oxygénation active. Trois mois post-transplantation, la fraction excrétée de sodium et le ratio protéinurie/créatininurie étaient plus élevé dans le groupe W. La créatininémie était plus faible dans le groupe W-M101. La fibrose interstitielle a évalué à 3 mois post-transplantation étaient plus faible dans les groupes W-M101 et W-O2+M101. Nous avons révélé histologiquement que l’infiltration de mastocytes était significativement élevée dans le groupe W comparé aux autres groupes. Nous avons montré que la combinaison de 21% O2 + hémoglobine améliorent la reprise de fonction du greffon rénale. / Introduction: It is proved that preservation of marginal kidney graft in machine perfusion (MP) is beneficial. However, this method requires improvement to minimize the ischemia-reperfusion injuries (IRI), as addition of oxygen and/or an oxygen carrier. We aimed to evaluate the effects of oxygenation (100% or 21%) and the addition of marine worm hemoglobin (HbAm, M101) during hypothermic renal perfusion before transplantation. Our endpoints were based on graft function recovery and late renal dysfunction. Method and materials: We use a porcine model where kidneys were submitted to 1h warm ischemia, followed by WAVES® MP preservation for 23h before auto-transplantation. Four groups were studied: W (MP-21% O2), W-O2 (MP-100% O2), W-M101 (MP-21% O2 + 2g/L HbAm), W-O2+M101 (100% O2 + 2g/L HbAm), (n=6 per group). Results: Kidneys preserved in W-M101 group showed a higher perfusion flow and lower renal resistance, compared to other groups. During the first week post-transplantation, W-O2 or W-M101 groups showed lower blood creatinine and better glomerular filtration rate. Blood levels of KIM-1 and IL-18 were lower in W-M101 group, while blood levels of AST and NGAL were lower in groups with 100% O2. Three months after transplantation, the fractional excretion of sodium and the proteinuria/ creatininuria ratio were higher in W group. Blood creatinine was lower in W-M101 group. Interstitial fibrosis evaluated at 3 months was lower in groups W-M101 and W-O2+M101. We showed that the combination 21% O2 + hemoglobin improves the kidney graft outcome.Conclusion: We showed that the combination of 21% O2 + hemoglobin improved the kidney graft outcome.

Title: Occurrence of coordination disorders in children with hearing impairment Objectives: The aim of this master thesis was to verify the hypothesis that children with hearing impairment have higher incidence of sensorimotor issues byassessing their motor skills, physical fitness and somatognostic functions. A partial goal was to assess the correlation between the methods used. Methods: The examination group consisted of 73 children (27 girls and 46 boys) with hearing impairment aged 7 to 16 years (mean age 11.9 ± 2.8 years). The mean weight of the children was 47.7 ± 17.4 kg, the mean height was 153 ± 17.5 cm and the average BMI value was 19.7 ± 4.1. Following methods for testing of children with hearing impairment were utilized: the Movemet Assessment Battery for Children - Second Edition (MABC-2) and Unifittest 6-60. Results were evaluated according to Czech standards. All children were also tested for their somatognostic functions according to Kolář. Furthermore, anamnestic data were obtained from parents of 54 children using a non-standardized questionnaire. In the case of 20 children, the assessment was repeated after 3 years. Statistica and Microsoft Excel 2016 were used for data processing. Results: The hypothesis was confirmed, i.e. children with hearing impairment have higher incidence...

Bakgrund: Donation efter primär hjärnskada (DBD) har utförts i Sverige sedan 1981 och ärden vanligaste formen av donation. Donation efter cirkulationsstillestånd (DCD) infördes iSverige 2020 och ökar i omfattning. I länder där DCD redan är etablerat beskrivskunskapsnivån som låg i förhållande till DBD vilket leder till en känsla av otrygghet hosvårdpersonalen.Syfte: Att kartlägga hur intensivvårdssjuksköterskans skattar sina kunskaper och erfarenheter ivården av potentiella donatorer över 18 år enligt DCD processen.Metod: Enkätundersökning med kvantitativ design genomfördes. Enkäten skickades ut till 11intensivvårdsavdelningar i Sverige.Resultat: Består av svar från 58 respondenter. Majoriteten av respondenterna har fått teoretiskoch praktisk utbildning i att vårda en potentiell donator i DCD processen. Över 50% svararockså att de fått utbildning i att stödja donatorns närstående. Samband finns mellan kunskapoch utbildning men även mellan utbildning och skattad trygghet.Konklusion: Tydliga samband ses i studien mellan utbildning och kunskap. Kunskapen i sintur visar tydliga samband med intensivvårdssjuksköterskans skattade erfarenhet av trygghet ivården av den potentiella donatorn men även erfarenheten av att stödja/bemöta och besvarafrågor från närstående. Utbildningen är en viktig faktor för att förberedaintensivvårdssjuksköterskan i vården av en DCD. / Background: Donation after brain death (DBD) has been performed in Sweden since 1981 andis the most common type of donation. Donation after circulatory death (DCD) was introducedin Sweden in 2020 and is increasing in scope. In countries where DCD already is establishedthe level of knowledge is described as low in relation to DBD which leads to a feeling ofinsecurity of healthcare professionals.Purpose: To map how intensive care nurses estimate their knowledge and experiences in thecare of potential donors over the age of 18 according to the DCD-process.Method: Survey study with a quantitative design. The Survey was sent to eleven intensive careunits in Sweden.Result: Consist of answers from 58 respondents. The majority of the respondents receivedtheoretical and practical education in the care of a potential donor in the DCD process. Morethan 50% also received education to support the donors’ relatives. Correlations were shownbetween knowledge and education but also between education and a feeling of security.Conclusion: A clear correlation is seen in the study between education and knowledge.Knowledge in turn shows correlation to the intensive care nurse ́s valued experience in the careof a potential donor but also to the experience of supporting and answering questions from itskin. Education is an important factor to prepare the intensive care nurses in the care of a DCD.
