Effectivness of vestibular stimulation in patients with postural stability disorder
Ševčíková, Lucie ; Čakrt, Ondřej (advisor) ; Bitnar, Petr (referee)
The diploma thesis summarizes physiology of vestibular system and disorders of vestibular system. In experimental part we observe the influence of vestibular stimulation on static postural stability. We achieve vestibular stimulation by active and repeated head and body movements. We measure the lenght of COP trajectory using stabilometry. We tested two groups of persons, 20 healthy persons aged 21 - 49 years and 6 patients with postural stability disorder from vestibular origin aged 40 - 76 years. The changes in lenght of trajectory COP after vestibular stimulation were not statistically significant in any group, but for each patient, there was a change in lenght of trajectory of COP. In patients, who have peripheral vestibular disorder, there was a reduction in lenght of trajectory of COP. Powered by TCPDF (www.tcpdf.org)

The influence of walking speed on the ability to maintain a straight direction after rotational stimulation of labyrinth
Bradáčová, Andrea ; Čakrt, Ondřej (advisor) ; Jeřábek, Jaroslav (referee)
The theoretical part focuses on vestibular system - the formation and role of vestibular information in the control of bipedal locomotion, and processes issues of gait control with respect to walking speed and the use of sensory feedback. The experimental part deals with the effect of rotational stimulation of labyrinth on the ability to maintain straight walking direction with the exclusion of visual control at various speeds - slow walking, fast walking and running. Two groups were tested - younger group aged 21 - 30 years (29 people) and older group aged 41 - 55 years (15 people). The difference between deviations from a straight direction before stimulation (with the exclusion of visual control) and after stimulation appeared to be significant (p < 0.05) for slow walking, fast walking and running, but only in the younger group. In the younger group there was also a statistically significant difference between deviation for slow walking after rotational stimulation and deviations for fast walking and running after stimulation. In the older group there were statistically insignificant differences between deviations before and after stimulation and between various speeds. Younger and older group differed statistically significantly in response to rotational stimulation at slow walking. The results...

Rating postural stability in synchronized swimming
Koubková, Natálie ; Satrapová, Lenka (advisor) ; Stupková, Michaela (referee)
Title: Rating postural stability in synchronized swimming Objectives: The aim of the diploma thesis is to detect, with a use of the system Gaitview ® AFA - 50 systém (Foot Scanner), if synchronized swimming has effect on postural stability of synchronized swimmers. Methods: Therotical part of diploma thesis is about synchronized swimming, influence of the aquatic environment, postural stability, stabilization and balance. A sample of 113 female athletes aged 6-35, who were long term synchronized swimmers at competition level, was chosen for this survey. Postural stability of athletes was tested while standing still with open and closed eyes by Gaitview ® AFA-50 system (Foot Scanner). Measured data were processed through Gaitview software, Microsoft Excel 2010 and anaylzed by statistical methods (average percentage, ratio, linear trend). Results: Results confirmed the effect of synchronized swimming on athletes postural stability. The longer are athletes dedicated to synchronized swimming the better is postural stability. From the age of 15 years and after 9 years of experience in synchronized swimming postural stability was shown to be better without access to visual information than with it. In the youngest category there is the biggest difference in postural stability while standing still with...

Summary of occupational therapy tests with possible use in testing dyspraxia
Holubová, Kateřina ; Demeková, Júlia (advisor) ; Zounková, Irena (referee)
The aim of the thesis was to find occupational therapy tests, or part thereof which could be used to test various inputs perception function of CNS. In cooperation with child and adult occupational therapists from Motol Hospital were researched occupational therapy various standardized tests designed to test children and adults. Then of them selected those tests (or a portion thereof) that contain the testing of individual sensory modalities of adult patients. Ultimately, these tests were applied to a group of adult population and evaluated. The whole work was compiled in the form of research. It was assumed that in the sets occupational therapy standardized tests, there are tests or parts that are able to focus their testing different modalities of perception function of the CNS within the cortical functions.

Influence of aging on postural stability in different servical spine position.
Zelený, Matěj ; Čakrt, Ondřej (advisor) ; Bitnar, Petr (referee)
The quality of sensory information which is necessary for balance and postural stability is changing throughout aging. It is closely related to increasing cases of injury caused by fall of elderly people. The aim of the diploma thesis is to explain the effect of age to the postural stability especially during varied cervical spine positions. The theoretical part of the thesis deals with a control of balance, role of vision, vestibular and somatosensory system, influence of static and dynamic movements of cervical spine to postural control. Within the experimental part we carried out a posturographic examination of standing stability in two groups of healthy people varying age. The destabilization effect was objectify by measurement of the average velocity of center of pressure during upright head position, extension of cervical spine and theirs dynamic movements in sagittal plane. The extension of cervical spine increases difficulty of performance certain posturographic tests and it is used in unrevealed compensated deficits of stability. This unusual position causes falls in elder people. Destabilization effect is expected within increasing speed of the sagittal movement of the cervical spine during examination of dynamic locomotion. Control of stability and head orientation might be used for...

Physiological development of posture and movement in pre-school children - vestibular apparatus
Bočínská, Helena ; Zounková, Irena (advisor) ; Syslová, Jana (referee)
This work is aimed at the development of posture and movement in pre-school children. Specific focus is placed on the control of posture and movement of vestibular apparatus. The study is drawn upon thorough research of Czech and English literature; and initially, some information was gained from foreign articles published in electronic magazines. The study concerns pre-school children and its emphasis is hence put on this particular period of human development. In presented findings, particular focus is put on anatomy, embryology, and neurophysiologic aspect of vestibular apparatus. The overview is chronologically structured and goes from prenatal to pre-school stage. The impact of vestibular apparatus on development of movement is reflected in consequent improvement of motoric skills. The work focuses on the impact of vestibular system on the control of posture in pre-school children, and its increasing responsibility for control of posture and movement in relation with visual sensory and somatosensoric system. The case study concerning motorics of healthy children serves as a useful tool in verifying the findings about the impact of vestibular apparatus on the control of posture.
