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.

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.

Risk assessment, prevention and health support at a workplace of a selected plant in the Olomouc administrative region
SVOBODOVÁ, Klára
The objective of this work was to assess the health risk of local muscular stress of the upper limbs associated with the operator's job at a workplace of a selected plant in the Olomouc administrative region and to propose adequate provisions. Three research questions were asked: (i) "Are the permitted levels, set as percent fractions of the maximum load, complied with in the operator's job?" (ii) "Are the hygiene limits regarding the numbers of movements complied with in the operator's job?" (iii) "Which preventive actions are suitable to counteract the risk of local muscular stress during machinery assembling work?" This research was conceived as qualitative investigation. The group examined comprised employees at the position of operator at a workplace of a selected plant in the Olomouc administrative region. The research work comprised data collection by using the method of direct, non-participating and overt observation, and study of professional literature, applicable legislation and test protocols and reports. I processed the results of measurement and compared them with the hygienic limits laid down by Government Decree No. 361/2007 Coll. (as amended). Based on the assessment of the data obtained, I classed the operator's job as Category 3 with respect to the local muscular stress factor examined, based on the criteria set by Regulation No. 432/2003 Coll. (as amended). Based on the risk assessment and categorization of labour I proposed appropriate preventive measures to mitigate the effect of local muscular stress during the operators' work. I set up a simple questionnaire asking for a subjective assessment of the locomotive system stress during work as a tool for a more comprehensive assessment of the operators' local muscular stress. Based on the research I formulated the following hypothesis: "In view of the increasing trend of incidence of occupational diseases of the limbs due to overload, and taking into account the appreciable social and economic impacts of such diseases, more attention should be devoted to a systematic search, assessment and evaluation of the local muscular stress factor risk during work."

Role of the Nurse in the Electromyography examination
PELEŠKOVÁ, Adéla
The electromyography (EMG) is a technique capable of recording the electrical activity produced by skeletal muscles and examining whether nerves are sufficiently supplied. The electromyography is carried out in some neurological ambulances or EMG laboratories. Together with a practitioner, it is a nurse who has an unsubstitutable role. The epithet ``assisting{\crqq} belongs inseparably to the nurse´s profession. Her behaviour, acting and attitude can affect {--} positively as well as negatively - lots of the people with whom the nurse gets in touch.
