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.

Transtibial prosthesis for recreational swimming
Křemen, Jan ; Mazůrek, Ivan (referee) ; Paloušek, David (advisor)
This thesis deals with the construction of an active transtibial prosthesis for recreational swimming. Its aim is to create a working sample of such a prosthesis. The device will primarily serve the patient to move in water - it will be attached to the stump and it will be driven forward. Secondarily, the prosthesis can be used for walking, in the sense that the patient attaches the prosthesis near to a water surface (pool, lake, ocean) and comes with it to the shore. As part of the design and electronics it will be necessary to determine the characteristics of the human resistance in water depending on speed and to determine the necessary propulsion (thrust) strength of the propeller, which will serve as the driving force. Subsequently there will be formed structural variants and selected the best one. This will become default for design and construction of simplified testing device, which will be tested for static thrust. After verifying the functionality and reliability, the final functional sample will be manufactured and tested too.

Upper Extremity Prosthetics
Tomanová, Markéta ; Janoušek, Oto (referee) ; Kolářová, Jana (advisor)
Bachelor´s thesis summarizes the knowledge about prosthetic substitutes upper extremities, with a focus on myoelectric prosthesis, the bionic arm. Practical work provides an overview of the different types of upper limb prostheses, starting with cosmetic prostheses without the active functions, ending with active myoelectric hand. Literature search is performed, including the summary table comparing the advantages and disadvantages of each upper limb prostheses. The next section deals with directly myoelectric extremities, with a view to prosthesis individual companies to specialize their production of these prostheses. The practical part was focused on recording electromyographic signals directly intended to control myo-electric prostheses. The proposed block diagram shows the bionic arm components required for its activity. The included software allows to process signals measured using the Biopac system. The result is a functional work program based on the principle of detecting overthreshold impulses. Based on the resulting binary outputs there are the final results of the prosthesis control, both text and graphics, shown after adjusting.

The Upper Limb Prosthesis And Its Impact On A Patient's Mental State
Štechová, Eva ; Bachura,, Marek (referee) ; Zdařil, Zdeněk (advisor)
Bachelor's thesis deals with myoelectric upper limb prosthesis and it's effect on mental state of the patient. It was created as a collaboration with company OTTOBOCK SLOVAKIA s.r.o, company that distributes prostheses and other devices to help improve or preserve mobility for disabled patients. I chose one of their products, Greifer, and decided to do a redesign. Greifer is a prosthesis made for delicate work with small objects on one hand, on the other for harder work that requires a firm grip. I created the design with regards to ergonomics, functionality and aesthetic quality. My aim was to create a product that a patient would easily get used to, and it would not draw negative attention of other people, which would have negative effect on a mental health of the patient. Functionally I followed the today's Greifer system provided by Ottobock at first, but then I added the function of rotation around spherical joint, inspired by an actual human wrist joint.

Strength-strain analysis of dog prosthesis
Doležalová, Veronika ; Hrstka, Miroslav (referee) ; Vlach, Radek (advisor)
Bachelor thesis deals with strength-deformation analysis of dog prosthesis. Work contains introduction to problems of prosthesis and determination of kinematice during dog’s movements. The analysis was carried out using two approaches, both analytical and numerical. In conclusion, we compare the results of both computational approaches.

Design of composite prosthetic appliances production technology
Magula, Martin ; Slaný, Martin (referee) ; Zouhar, Jan (advisor)
This bachelor thesis deals with the topic of manufacturing a composite prosthetic arm. The first part of the thesis is devoted to the research of basic composite materials and technologies for the production of prosthetic devices. The second part of the thesis is focused on the practical manufacturing, where from the scanning of a previously made prosthesis we obtain a model. Following this part, a part of the arm will be fabricated and subjected to material testing.

A Case Study of Physiotherapy Treatment Concerning a Patient after Transfemoral Amputation
Lhota, Lukáš ; Novotná, Irena (advisor) ; Nový, Filip (referee)
Author: Lukáš Lhota Supervisor: Mgr. Irena Novotná Title: A case study of physiotherapy treatment concerning a patient after transfemoral amputation Objectives: The aim of this bachelor thesis is to elaborate the theoretical knowledge of lower limb amputations. Furthermore, I will present a case study of physiotherapy treatment of a patient with a diagnosis of unilateral transfemoral amputation and evaluate the effect of therapy with subsequent discussion. Methods: The bachelor thesis is divided into theoretical and special parts. The theoretical part is a research elaboration of kinesiological background and theoretical knowledge regarding lower limb amputations with a focus on the subsequent rehabilitation, especially its physiotherapeutic part. In the special part, a case report of a patient after transfemoral amputation, which was prepared in the Regional Hospital Kladno, is presented. The case report contains the patient's history and initial kinesiological analysis on the basis of which short-term and long-term goals were developed. It also contains a record of individual therapeutic units, an output kinesiological analysis, the effect of therapy and a subsequent discussion. Results: During the physiotherapeutic intervention, stump flexion was reduced, breathing waveform improved, lower limb,...

Case study of ortho-prosthetic care of a patient with a diagnosis of transtibial amputation
Kováčová, Veronika ; Neuwirthová, Svatava (advisor) ; Černý, Pavel (referee)
vi Abstract Title: Case study of ortho-prosthetic care of a patient with the diagnosis of transtibial amputation Objectives: The main goal of this bachelor's thesis is to process a case report of a patient with a detailed description of the production and application of a prosthetic device. Another goal is to process basic theoretical knowledge about anatomy, amputations and prosthetics of the lower limbs with a focus on transtibial prostheses. Methods: The bachelor's thesis is divided into a theoretical and a practical part. The theoretical part summarizes basic knowledge regarding anatomy, amputations and transtibial prosthetics of the lower limbs. The practical part contains a case study of a diabetic patient with the diagnosis of lower leg amputation, which consists of a description of their medical history, measurement taking and the process of manufacturing a prosthetic device. Results: The case report was prepared as part of my professional training at Protetika s.r.o. The result of the work is the creation of a new prosthetic device that will help the patient in his daily life and improve it. Keywords: amputation, prosthesis, transtibial, case report
