EMG biofeedback
Toman, Jakub ; Hrozek, Jan (referee) ; Janoušek, Oto (advisor)
The bachelor´s thesis describes the basic methods of bringing out the electromyographic data by invazive and noninvazive procedure. Further it is focused on the principle of the biological feedback and on the myofeedback and its essential characteristics. The created application can displays the progression of the maesured EMG, signalizes the overrun of the set up threshold and contains two simply games for myofeeedback.

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.

Acceleration and motion of upper limbs
Novotný, Adam ; Kolář, Radim (referee) ; Kolářová, Jana (advisor)
Purpose of this work is mainly the description of electrical plots in skeletal muscles and secondarily experimental verification and description of methods connected with measuring and evaulating biosignals. The theoretical presentation of muscle physiology facts is supplemented with an experiment using pair t-test, which describes procedures leading to evaluating particular hypotheses (the measured muscle is biceps brachii). In this work, the biosignal is an EMG signal, thus the electrical activity of muscle. Therefore, the main objective of this work is not only about using EMG as an examination method, but also about showing a complex view at the recording, processing and evaluating of EMG signal. These facts are supplemented with programm application which is showing the way working with EMG signals and also the possibilities of algorithm development in such signals.

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.

Electronics for muscle activity monitoring
Lavička, Jiří ; Vlach, Radek (referee) ; Krejčí, Petr (advisor)
This thesis describes the design and compilation of device for monitoring of muscle activity. You can find there a generally introduction of monitoring of this activity. Futheremore it pushes ahead process of plan of electronics and DPS. In final part of this thesis is shown summary of whole device and also there is a example of measurement.

Structural members of prostheses of upper extremities
Mužný, Lukáš ; Opl, Miroslav (referee) ; Matějka, Petr (advisor)
This bachelor thesis deals with the upper limb prosthesis. The target of the project is to create an overview of the distribution and types of prostheses and their individual elements. In particular, it deals with the problem myoelctric prostheses. Provides information on the biomechanics of human arm, specifies options grip of the object, gives an overview of the research centers and their substitutes developed upper limbs. It also focuses on the possibility of prostheses control by myoelectric signals.
