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.

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.

Monitoring the activity of selected groups of skeletal muscles during squats on balance pads using EMG.
Šidla, Jiří ; Bedáňová, Kamila (referee) ; Adamík, Richard (advisor)
This bachelor thesis is focused on the topic of monitoring the activity of selected groups of skeletal muscles during squats on balance pads. Thigh muscles of 21 probands (21,81 ± 2,06 years old, 184,53 ± 5,19 cm, 72,50 ± 4,75 kg) were measured using EMG when they did squats without balance pad and with five balance pads (BOSU concavely, BOSU convexly, T-bow, foam pad and Vicore). Ten of these persons was measured also with inflatable balance pod. Mean and mean of the 10 highest peaks of filtered and normalised measured signals were statistically analysed. There were some statistic differences of both parametres between measurement without balance pad and measurements with some balance pads (BOSU concavely, BOSU convexly, Vicore and balance pod) using analysis of all thigh muscles together, analysis of anterior-posterior stability and analysis of dexter-sinister stability. There were some statistic differences between these balance pads and the other two pads (T-bow, foam pad).

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.

Therapeutic game implementation with use of EMG signal
Drozd, Tomáš ; Kolářová, Jana (referee) ; Hesko, Branislav (advisor)
This bachelor thesis describes electromyography which we can use for biofeedback. At first, it describes electromyography and methods of measuring. Then biofeedback is described and its usage for therapeutic purposes or therapeutic games. Also it introduces BITalino device which represents low-cost solution for biofeedback. For practical uses there is provided a program written in C++ which includes Super Mario World. Appliation also draws measuered signal and parameteres calcuted from it.

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.

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.

Neuromuscular control of motor units in strength and coordination dependant tasks for lower limbs
Šádek, Petr ; Otáhal, Jakub (advisor) ; Ravnik, David (referee) ; Vláčilová, Ivana (referee)
Title: Neuromuscular control of motor units in strength and coordination dependent tasks for lower limbs. Objective: To compare muscle activity on the level of motor units through decomposition of surface electromyography signal from vastus medialis during given strength and coordination oriented movement tasks and to describe eventual differences in the parameters of tracked motor units in regards to given movement tasks. To assess the quality of chosen method for describing the muscle activity control on the level of motor units for further possible applications in the research and clinical environment. To summarize relevant knowledge acquired through the decomposition method of surface electromyography signal regarding the control of movement, motor unit activation and other relevant informations for clinical environment. Method: Theoretical part of the work presents the decomposition method, the process of its evolution and its constituent parts in the context of electromyographic evaluation of muscles along with selected chapters of neuromuscular kinesiology on the level of motor units. The experimental portion of presented thesis was carried out on 12 probands in the age of 23,2 (+- 5,3) years, who were instructed to perform the selected movement tasks of single leg squat in two different...
