Evaluation of Developmental Dyspraxia in Children and Adolescents in Relation with Handedness, and in Children and Adolescents with Learning Disabilities
Jínová, Anna ; Kraus, Josef (advisor) ; Zounková, Irena (referee)
10 Annotation This diploma thesis deals with relations between developmental coordination disorder (or developmental dyspraxia) and laterality and handedness. In the theoretical part this work summarizes actual knowledge about the origin and the development of laterality and handedness and describes possibilities how to examine it. It also deals with knowledge about developmental coordination disorder, its characteristic, etiology, prevalence and diagnostic possibilities. The aim of the practical part was to evaluate motor difficulties in children with right and left handedness and to compare differencies. The Movement Assessment Battery for Children 2 was used for that evaluation. Motor skills in 64 children (30 left-handed and 34 right-handed) were evaluated. We haven't found any difference between those groups of children, their results were very balanced. We have also tested the motor skills in children with crossed eye-hand laterality, any significant difference hasn't been found in comparison with standard population. The group of children with learning disabilities has been also evaluated, we have found statisticaly significant difference between their motor skills and motor skills of standard population.

Development of Test Batteries for Diagnostics of Motor Laterality Manifestation - Link between Cerebellar Dominance and Hand Performance
Musálek, Martin ; Chytráčková, Jitka (advisor) ; Tichý, Jiří (referee) ; Bryden, Pamela (referee)
The aim of this study is to contribute to the standardization of the new diagnostic tools assessing the motor manifestations of laterality in adults and children aged 8 to 10 years, both in terms of determining the theoretical concept and the selection of appropriate items, and the verification of structural hypotheses concerning the design of acceptable models, including the diagnostic quality of individual parts of the test battery. Moreover in this study we try to suggest new approach in assessing of motor laterality manifestation by means of relationship between cerebellar dominance and hand performance. The first part of this thesis deals with the concept of laterality, its manifestations and meaning in non-living systems and living organisms. As a human characteristic, laterality is manifested in a variety of functional and structural asymmetries. This part also discusses ways of diagnosing motor manifestations of laterality and the issue of cerebellar dominance, including its reflection in the form of asymmetry of the extinction physiological syndrome of upper limbs. The second part focuses on the process of the standardization study, the statistical method of structural equation modelling, and the actual design of test battery construction. The last part of this thesis presents the results...
