The acute effect of percusive therapy on postural stability and muscle activation in people with chronic ankle instability and controls
Michal, Lukáš ; Hank, Mikuláš (advisor) ; Šorfová, Monika (referee)
F2 = 0.15; with a significance level of α = 0.05 and a test power of β = - - (p=0.014) CAI NO PRE (CNP) and HEALTHY YES POST (HYPO) and between the CAI NO POST (CNPO) vs. HYPO (p=0.05). The only statistical difference (p=0.045) within CAI group was found in CNP vs. CAI YES POST (CYPO). Since there was no significant difference in the pre-tests between any of the groups (CNP and CYP), we may confirm the hypothesis of the effect of PT in postural stability (OE) test. In contrast, in the CE test, this change was observed between groups CNPO and CYPO (p=0.05). Since there was no pre-test difference between the CAI groups in CE parameter, we may also confirm the effect of PT in CE test, even though the intragroup outcomes between pre and post-test weren't sensitive enough to find significant (p<0.05) improvement. Unilateral postural stability surveyed in relation to PT showed increased bilateral asymmetry between DOM and NON in Flamingo test (expressed as %). Especially HYPO group revealed risen asymmetry after PT when compared to CNPO (p=0.007), CNP (p=0.015) and CYPO (p=0.05). Key finding was measured significant difference in intragroup parameter between HYP vs. HYPO (p=0.014), which confirmed increased bilateral asymmetry in unilateral postural stability HEALTHY subjects before and after use of PT, but not...

Podněty svalové činnosti při chůzi a běhu na pevném povrchu a chodícím pásu
Čurda, Josef ; Šťastný, Jan (referee) ; Korvas, Pavel (advisor)
This term paper deals with the difference in the electrical activity of muscles when walking and running on a solid surface and when walking and running on a treadmill. The measurements are performed using a Cometa Wave plus multichannel electromyograph. Software evaluation is performed using EMGandMotionToolsv software from © 2018 Logemas Pty Ltd. Results are processed in MATLAB software from MathWorks (R2021a). The theoretical section describes the physiological processes occurring in the neuromuscular system, muscle structure and an explanation of the concept of EMG. The practical part includes methodology, measurement protocol, research questions, stated objectives and results of the work evaluated in the conclusion.

Upper limb gesture recognition from EMG recordings
Kostial, Martin ; Smital, Lukáš (referee) ; Harabiš, Vratislav (advisor)
This work covers gesture recognition from upper limb sEMG recordings, designing a custom classifier using machine learning. The thesis is divided into six chapters – the first describes the EMG signal properties, the second discusses current EMG evaluation methods using machine learning, the third presents the actual implementation of the recognition algorithm, the fourth one deals with capturing the actual EMG recordings, and the fifth one is a discussion of the obtained results.

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.

Control of low-cost prosthetic limb using EMG sensors
Šafran, Jindřich ; Brablc, Martin (referee) ; Rajchl, Matej (advisor)
This Bachelor thesis is about the general design, construction and model assembling of the prosthetic arm. Its programming and controlling of the robotic part are also included. The thesis is divided into five chapters. In the first chapter, the anatomy of forearm is analysed and described. Its anatomical structure is the theoretical base on which the final model is designed and constructed. Following, second chapter, comprises the analysis of prosthetic mechanisms according to the historical development up until today. And this chapter also contains the production of the designed forearm-hand-model itself. The third chapter describes the EMG diagnostic method and the process of manufacturing of each compartment of controller device used for controlling the mechanism of the designed model. Next, chapter number four contains gaining and processing of the data from testing of the measuring device. In the last fifth chapter, the programming of the made forearm-hand-model in various development environments is described. All the results and gained knowledge, are evaluated and described in the conclusion of the Bachelor thesis.

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.
