Graphomotor abilities (GA) represent a set of psychomotor activities that are executed during drawing and writing. The GA are prerequisites for mastering of elementary school skills, particularly writing. Children in 1 st and 2 nd grade can experience difficulties in execution of simple graphomotor tasks (GD) and later in 3 rd and 4 th grade even in handwriting tasks (HD). The disruption of processes involved in handwriting is generally called Developmental Dysgraphia (DD). The prevalence of DD in the Czech Republic is 3–5 %. To this day the DD is evaluated subjectively by teams of psychologists and special educationalist. Currently, an objective measuring tool that asses the properties of GD or HD is missing in practice. Consequently, this thesis is aiming to identify symptoms associated with graphomotor disabilities in school–aged children and design new parameters quantifying them. For this purpose, a new complex GA protocol was proposed (36 tasks), which represents an environment, where the identified symptoms can be manifested (24 symptoms). Moreover, 76 quantifying features were introduced. A new graphomotor difficulties rating scale (GDRS) was designed based on computerised analysis of handwriting. Finally, new online handwriting parameters based on advanced signal processing techniques were designed and tested, which can assess poor dexterity or unspecified motor clumsiness. The GDRS represents a novel and modern objective measurement tool, that is not yet available in the Czech Republic or in other countries. Its utilization will help in the modernization of DD diagnosis and in the remediation process. With proper research, it could be adapted into other languages as well. Moreover, the methodology can be used and optimized for other diseases, which affects GA, such as Autism, Attention Deficit Coordination Disorder (ADHD) or Developmental Coordination Disorder (DCD).

Psychomotorické hry jako prostředek rozvoje grafomotoriky u dětí předškolního věku
Sochorová, Denisa ; Nováková, Pavlína (vedoucí práce) ; Vařeková, Jitka (oponent)
Název: Psychomotorické hry jako prostředek rozvoje grafomotoriky u dětí předškolního věku Cíle: Cílem práce je zhodnocení úrovně grafomotoriky v Mateřské škole u dětí předškolního věku a zhodnocení vlivu psychomotorických cvičení a her na rozvoj grafomotoriky u předškolních dětí. Metody: Jedná se o kvaziexperiment, jež pracuje s cíleným výběrem skupiny probandů, a to dětí z konkrétní Mateřské školy. Bylo vybráno celkem 12 dětí a rozděleno po šesti na skupinu výzkumnou a kontrolní. Obě skupiny zahrnují celkem šest probandů, čtyři chlapce a dvě děvčata. Úroveň grafomotoriky byla testována pomocí testu kresby postavy a testů z baterie MABC-2. Zároveň se jedná o kvalitativní výzkum, kde se sleduje kvalita provedení jednotlivých úkolů a hygiena psaní na základě nestandardizovaného pozorování. Výsledky: Výsledky výstupních testů ukázaly zlepšení kontrolní skupiny dětí, u nichž nebyly aplikovány psychomotorické hry. Obě skupiny měly lepší výstupní výsledky u testů kresby postavy i u testů jemné motoriky z baterie MABC-2. Klíčová slova: Psychomotorické aktivity, dětská kresba, grafomotorické dovednosti, předškolní věk, kresba postavy, jemná motorika
