Affect of standing frames on muscle activity of lower extremities
Oravová, Pavlína ; Ronzhina, Marina (referee) ; Kolářová, Jana (advisor)
Bachelor thesis is focused on affect of standing frames on muscle activity of lower extremities. It deals with problematics of electromyography and signal processing. It follows up measuring EMG signal via wireless electrodes Wave Plus on verticalization equipment Balance Trainer and muscles of the lower extremities physiology, which were picked up for practical part of measurement. Part of this thesis is measuring protocol. Futhermore, the captured data is processed by programming interface MATLAB and evaluated in discussion.

The variability of the distribution of pressure forces on the foot with coupling EMG
Semeráková, Nikola ; Kolářová, Jana (referee) ; Koťová, Markéta (advisor)
The bachelor work is focused on the distribution of pressure forces in the area of the foot with support from electromyography. Part of the work deals with the physiology of leg muscles and where the groups of muscles responsible for standing are defined. After that the thesis focuses on postural stability, the foot vault and biomechanical parameters. Additionally, there's the defining of the principles of electromyography and dynamic pavement. Furthermore, the thesis focused on describing how the data is processed, first from elektromyograph and then from dynamic pavement. Finally, there are outcomes from these devices, which are compared and evaluated,there are also partial parameters for electromyography and for the dynamic pavement.

Device for measuring the electrical activity of muscles
Slouka, Petr ; Chmelař, Milan (referee) ; Balogh, Jaroslav (advisor)
This thesis contains introduction to the basic principles of creation and transmission of action potentials. Afterwards it is outlined development of electromyography which is used for measuring electrical signals from muscles and attributes of electromyographic signal. Next part describes design of the device for measuring electrical activity of muscles. Thesis contains diagrams of the integrated circuit, design of printed circuit board and list of components which are needed for realization of the device.

Kinematic analysis of movement of cyclist with transtibial prosthesis.
Stoklásek, Pavel ; Mazůrek, Ivan (referee) ; Paloušek, David (advisor)
This work is aiming to the area of biomechanics and deals with the experimental finding of appropriate kinematic ratios of crank mechanism on racing bicycle and transtibial prosthesis of racing cyclists with an assessment of kinematic ratios depending on the overall athletic performance. The primary aim of the work is investigation of the impact of inappropriate existing kinematic ratios of leg prosthesis and crank mechanism on the kinematics and dynamics of top athlete. The work presents experiments that proposes find out appropriate kinematic ratio of the length of kinematic members and possibility to improve overall athletic performance. The measurement is supplemented about cycling analysis of racer realized via cameras tracking system and measuring muscle activity by EMG. The work also includes a description of impact of various factors on cycling.

Fatigue evaluation using electromyography
Mošnerová, Jitka ; Chmelař, Milan (referee) ; Janoušek, Oto (advisor)
The aim of the diploma thesis is the design and implementation of methods for detecting fatigue in electromyogram (EMG). At first is done a literature review on the topic of fatigue detection in electromyography (EMG). Measurement of fatigue-induced changes in the EMG signal is performed on ten subjects using the Biopac ©. Next is in the thesis solved the selection of the optimal methods of evaluating the fatigue-induced changes in EMG recording using statistical testing. In the final part of the thesis is discussion on the results of statistical testing, creation a user interface in Matlab © and comprehensive instructions for laboratory focused on the topic of fatigue in the EMG signal.

Electromyography, measurement of muscle electric activity
Kořínek, Peter ; Provazník, Ivo (referee) ; Kolářová, Jana (advisor)
The task of this thesis was to become acquainted with the issue of measuring of muscle electric activity.In the theoretical part we became familiar with the computer measuringsystem BIOPAC and its options to measure monitored magnitudes. This continue with practical part, in which we watch the problematic according to a theory in a group of people. We learned data with BIOPAC according to protocol of the result of physicaleffort influence on EMG. In the end the results were statistically analysed. The data as a product offallowing research were verified by hypothesis. In thelast step, the data are presented in graphical user interface development environment. After loading of the EMG of measured person, the process are displayed-without, with and after the power with onus. It is possible to choose from different analyses.

Electromyography in therapy
Janoušek, Oto ; Hrubeš, Jan (referee) ; Kolářová, Jana (advisor)
The Master’s thesis describes electromyographic methods and it is focused on one of them - myofeedback. There are described principle, realization and application of myofeedback in this thesis. There is explained positive influence of using therapeutic games in therapeutic process. The diploma thesis deals with a realization and description of MFB-Amos apllication which allows to upgrade an electromyograph by myofeedback enabling of using the therapeutic games. Application allows measure of EMG signal and consecutive analysis, and offers three therapeutic games.
