Electrostimulation method for cardiomyocyte life extension
Čermáková, Adéla ; Smital, Lukáš (referee) ; Čmiel, Vratislav (advisor)
This work deals with the electrophysiology of cardiac cells, their electro-stimulation and design of stimulation device to extend their life. The first part is focused on the action potential in general, in muscle cells, followed by an analysis of the process and characteristics of the action potential in cardiomyocytes. The next section provides a procedure for isolating and process of changes that lead to cell death and of a method that the process would be eliminated. Part of this work is a program for processing and evaluation of pictures obtained during electro-stimulation process.

Electrostimulation method for cardiomyocyte life extension
Čermáková, Adéla ; Ronzhina, Marina (referee) ; Čmiel, Vratislav (advisor)
This work deals with electrostimulation cardiomyocytes and design stimulation device for their cultivation and stimulation. First part of work deals with electrophysiological myocytes and the next problems with electrostimulation and preserved their original morphology and physiology structure. The following section is designed and constructed stimulation device to improve cell viability. Stimulation took place under different conditions and the success rate depends on the number of cells that survived.

Electical stimulation of hand muscles
Hrozáň, Michal ; Balogh, Jaroslav (referee) ; Sekora, Jiří (advisor)
Bachelor thesis explains the effect of electrical stimulation on muscle and nerve fiber. It describes the process of stimulation and principles that apply while stimulation with electric current is applied. Specific muscle stimulation of thumb is described. Work provides a solid base of knowledge for understanding the processes that are present in stimulation of living tissue, which will be implemented in construction of stimulator. User graphical interface was created in Matlab. User can communicate using this program with microcontroller ATMega328 of Arduino Uno Board. Microcontroller processes received data and generates voltage on its output pins. An amplifier and electrode triggering system was designed as well.

Use of electrostimulation according to Jantsche and Hufschmidt to influence triceps surae muscle spasticity and walking speed in patients with multiple sclerosis
Tichá, Simona ; Demeková, Júlia (advisor) ; Hojková, Klára (referee)
This thesis focuses on comparing the effectiveness of two types of electrostimulations, specifically electrostimulation according to Hufschmidt and Jantsche, in reducing m. triceps surae spasticity and influencing walking speed in patients with multiple sclerosis (MS). The aim of the thesis is to determine which type of electrostimulation is more suitable for patients with MS. The topic was chosen based on two previous theses that examined the effects of these electrostimulations individually. The theoretical part provides basic information about MS, explains the pathophysiology of spasticity and the possible influence of spinal mechanisms on it, describes the examination of spastic patients, and summarizes the possibilities of electrotherapy treatment. The practical part compares the effects of both types of electrostimulations in patients with MS who were partially randomly divided into two groups of three and evaluates short-term and long-term results using the "Five step clinical assessment in spastic paresis" examination and the subjective perception of walking questionnaire MSWS-12 (Multiple Sclerosis Walking Scale). The results of the thesis do not show significant differences in the effects of both electrostimulations. The most significant improvements in both groups were observed in the...

Distant effects of muscle electrostimulation
Koláček, Michal ; Slabý, Kryštof (advisor) ; Demeková, Júlia (referee)
This work is trying to identify possible non-stimulatory effects and distant effects of muscle electrostimulation musculus quadriceps femoris based on a literature search. Furthermore evaluates the influence of High Tone Electrical Stimulation (HTEMS) muscles of lower limbs on the activity of the autonomic nervous system, expressed by heart rate variability, a spectral power in the individual frequency bands. Randomized crossover study involved 15 healthy subjects (7 men and 8 women), average age 24.4 ± 2,5 years. Heart rate variability was evaluated in two situations: the situation without the application HTEMS and the situation with the aplication of HTEMS. Electrostimulation was done with HITOP 191. The results did not show statistically significant differences in all monitored components. The study also dealt with the reproducibility of measurements of perception and motor threshold for HTEMS.

The use of Electrotherapy to Influence Spasticity in Patients after Stroke
Pokorná, Anna ; Jeníček, Jakub (advisor) ; Tichá, Monika (referee)
Title: The use of electrotherapy to influence spasticity in patients after stroke Abstract: The theme of bachelor thesis is the use of electrotherapy to influence spasticity in pacients after stroke. The thesis is divided into two parts - theoretical and practical. In the theoretical part there is described the issue concerning stroke, regulation of muscles tention and spasticity. Mostly there is stated performed research of accessible literary sources on the theme electrotherapy with antispastic effect. These findings come out mostly of the results of foreign studies, which are being mutually compared. Pratical part contains of two case reports of patients, who suffered a stroke and spasticity m. triceps surae has occured in them. On the concrete muscle the stimulation according to Janstch is being applicated for five days. The impact on spasticity is being observed, the spasticity had been examined by using the scale Five-step clinical assessment according to Gracies before the first therapy and instantly after the fifth therapy. Further the changes of parameters, which are desribed by the stated scale, had been observed. The aim of the thesis is to summarize and enrich the issue at the same time and on the basis of the results of own therapy to evaluate the impact of electrotherapy. Key words: stroke,...

Cacuistry of pahysiotherapy care for a patient diagnosed with peripheral facial palsy
Berežná, Jana ; Kučerová, Ilona (advisor) ; Hrdličková, Svatava (referee)
Thesis title: Casuistry of physiotherapy care for a patient diagnosed with peripheral facial palsy Aim of the thesis: The aim of the thesis is to present theoretical information about the peripheral facial nerve palsy diagnosis. Further, the practical part of the thesis describes the use of chosen physiotherapeutic ways of the diagnosis treatment. Methods used: The theoretical part of the thesis presents anatomical context, clinical symptoms, ways of examination, treatment possibilities, including physiotherapy, and information about parotidectomy which may cause the peripheral nervus facialis palsy. The practical part of the thesis describes in detail the casuistry of the patient diagnosed with the peripheral nervus facialis palsy after operation of glandula parotis. Specifically, entrance clinical examination, short-term and long-term plan are made out, followed by records of nine therapy sessions and final output kinesiological analysis. Keywords: peripheral palsy, nervus facialis, adenom glandula parotis, Kenny Method, electrostimulation, kinesiotaping, mimic muscles

Neurophysiological indicators of muscle work on the paddle trainer and their electrostimulatory influence
Choutka, Jan ; Kračmar, Bronislav (advisor) ; Chrástková, Martina (referee)
Title: Neurophysiological indicators of muscle work on the paddle trainer and their electrostimulatory influence Objective:The main objective of this study is to compare the effect of the electromyostimulation neurophysiologic parameters of muscle aktivity during paddling on ergometer, Methods: The character of the research is quantitative and qualitative, case study, _________pilot study, comparative analysis of muslce activity neurophysiologic _________parameters using electromyography. Results: We have found differences in timing of muscle activation between the pre- and the post-test. The EMS caused dissolution of the differentiation of muscle patterns that have been built by specific training process of the monitored person. Key words: Electromyography, electromyostimulation, stroke, canoeing.
