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.

Presentation of selected themes of BSIS in PPT-environment
Havlín, Radomil ; Šebesta, Vladimír (referee) ; Sigmund, Milan (advisor)
The bachelors thesis occupy by topics of the course BSIS, which can be presented by the multimedia and animation techniques in the presentation. In the introduction, these topics are given a different method of processing. In most cases, provides a modular solution by demonstration and argued spectrum signal. The chapters describe the operation with one, two signals at the time, the properties of Fourier transform with illustrative demonstration, the correlation with convolution, kvaziperiodické signals and the last chapter the spectrum of selective signals.

Robotic hand control by myopotentials
Jablonská, Dominika ; Janoušek, Oto (referee) ; Bubník, Karel (advisor)
The thesis deals with the measurement of myopotecials and their using in controlling the robotic arm. First, it is theoretically described electromyographic signal, his scanning and subsequent processing. There is also described an arm which it is used here. The next aim of this project is paying attention scanning signal on human hands using Biopac system and signal processing in MATLAB with Robotic Toolbox. Also was created a computer model in the user interface GUI.

Effectiveness of rehabilitation of the upper limb
Rexová, Natálie ; Kolářová, Jana (referee) ; Horáková, Pavla (advisor)
The purpose of this bachelor‘s thesis is to examine muscle bioelectrical activity and its measuring in the BIOPAC system. To better understand this subject this bachelor’s thesis takes interest in a muscle tissue and all its main structure. It is also focused on electromyography as a significant diagnostic method in medicine. Subsequently there is an introduction to the practical part of bachelor‘s thesis. In this chapter the main focus is aimed at monitoring the parameters of the surface EMG signal of brachioradialis muscle. The measurements are collected in three phases, before, during and at the end of the proposed process of the strengthening of brachiotadialis muscle. The measured values are statistically processed and then interpreted. The final chapter seeks to specify the motivational activities and the enhancement of effectiveness of exercise.

Forearm prosthesis
Vařečka, Martin ; Sekora, Jiří (referee) ; Balogh, Jaroslav (advisor)
Bachelor’s thesis is focused on design of active hand prosthesis. This thesis summarizes upper limb anatomy focused on forearm. Then deals with amputations techniques and indication for amputation. Part describing contemporary prosthesis is important to design an active forearm prosthesis, který je popsán v třetí a čtvrté kapitole. The system processes biosignals using instrumentation amplifiers. The signals are evaluated by the Arduino development board, which mediates control of servo motors.

Effect of surface electrode type on quality of decopmposition of surface EMG signal
Strusková, Edita ; Otáhal, Jakub (advisor) ; Michalec, Radim (referee)
Title: Effect of surface electrode type on quality of decomposition of surface EMG signal Objectives: The aim of this thesis is to evaluate the effect of surface electrode type, which was used for EMG record, on the quality of decomposition of surface EMG signal using decomposition software EMGlab. Methods: The form of the thesis is an experimental essay. It was detected an EMG signal from one healthy volunteer during mild cyclic contraction. It was used three different types of electrodes (standard surface electrode, tetrode, tetrode with saw-off spikes) for EMG signal detection. These signals were decomposed in program EMGlab. The results were processed in program MS Excel, compared with each other and graphically displayed. Results: The measurement verified a hypothesis which claimed that the used type of electrode affects the quality of automatic decomposition. The best results of automatic decomposition provide the signal gained from the standard surface electrode. Key words: action potential, decomposition, surface electrodes, EMG signal, tetrode, electromyography
