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.
