The influence of eye movement on postural stability
Míková, Monika ; Kolářová, Jana (referee) ; Němcová, Andrea (advisor)
The Bachelor thesis discusses the influence of eye movement on postural stability. Thesis includes problematics of postural stability, physiology of sight, oculomotoric and measuring of eye movement via electrooculography method. Postural stability is measured with Wii Balance Board, which records antero-posterior and medio-lateral displacement of the COP position. Eye movements are measured with Biopac system, its output is EOG. Ten people were involved in this study. Parameters were calculated from stabilometric signal and from EOG. Results were procesed statistically.

Methods for the evaluation of postural stability
Nevěčná, Leona ; Janoušek, Oto (referee) ; Koťová, Markéta (advisor)
This study deals with methods for evaluation of postural stability. The main problem of posturography is lack of standardization in measurement and evaluation. There are presented some parameters affecting postural stability that are often taken into account. Those are parameters that might be changed while measuring, for example standing position, sampling duration or visual control. And others that are altered when evaluating is taking place, variability of those parameters, is much greater. Measurement protocol taking into account the most promising parameters was put together based on literary search. Changes in COP of ten subjects were measured with Wii Balance Board, according to the proposed measurement protocol. The data acquired from a particular subject were used to count values of parameters used in evaluation. After that the values were statistically analyzed. To compare each parameter, trajectory with good results according to other literature was chosen to pose as a reference. Final result is comparison firstly between importance of changes in parameters of measuring and secondly between success of detection of those changes of separate parameters.

Analysis of stabilometric signals in frequency domain
Netopil, Ondřej ; Hejč, Jakub (referee) ; Kozumplík, Jiří (advisor)
This work deals with the metods frequency and time frequency analysis of stabilometric signal. In the introroduction is described theory about posturography and posturographic measurment. The work contains describtion of stabilometric parametrs in time domain (1D and 2D parametrs) and in frequency domain. The aim is create review of basic metods used to processing and preprocessing of stabilometric signals and comparing this methods . In work is realized ferquency analysis used Frourier transfrmation and Burg method and time-frequency analysis used Short time Frourier transformation and Wavelet transformation. One part of program is aimed on comparison of this methods.

Evaluation of therapy cognitive and motor functions with technical equipment
Arimiyawu, Lenka ; Gerlichová, Markéta (advisor) ; Janatová, Markéta (referee)
The thesis evaluates the effect of four-week home therapy using stabilometric platform Nintendo Wii Balance Board and tablet with integrated software HomeBalance in patients with brain injury. Software HomeBalance has been developed for the treatment of balance disorders and cognitive function. Manipulating the platform and the tablet may also develop grip and handling abilities of hand, both will be evaluated in this work as well. The theoretical part describes new trends in rehabilitation of cognitive-motor interference, dual-task therapy and therapy using technological equipments. Methods: A total of 9 subjects underwent four weeks of therapy using a therapeutic set HomeBalance. The control group of 12 subjects received therapy without any technological equipment. Patients participated in the initial examination, home therapy and final examination. As an evaluation of the therapy Mini-BESTest, Timed Up and Go test, Montreal cognitive assessment, 9- hole peg test, and also two games from HomeBalance software and questionnaire assessing satisfaction with therapy have been used. Results: After treatment the whole group improved in only two tests evaluated: in Mini- BESTest and the time of diagnostic scene in HomeBalance software. The research group had statistically better results in both tests...
