Stress-strain analysis of lower limb prosthetic
Musilová, Kateřina ; Fuis, Vladimír (referee) ; Návrat, Tomáš (advisor)
This master thesis deals with lower-limb prosthesis. The aim of the first part of this work is stress-strain analysis of trans-tibial prosthesis, which is understand without prosthetic socket and the foam prosthetic feet. Analysis is made using finite element method in ANSYS Workbench 12.0 software. For the purpose of setting up the computational model it is necessary to make few partial models. Model of geometry of the prosthesis is made in SolidWorks 2009. Based on the outputs of stress-strain analysis and the results evaluation, the critical component is chosen and this one is evaluated according to limite state for fatigue. The algorithm of evaluation of named component in the state of high cycle fatigue is discussed in the second part of this thesis.

Lower limb prosthetics FEM analysis
Omasta, Milan ; Náhlík, Luboš (referee) ; Paloušek, David (advisor)
This masters´s thesis deals with computational modeling of transtibial lower-limb prosthesis. For assesment of loading character and geometrical configuration, the gait analysis of an amputee, including ground reaction force measurement, strain gauge analysis and motion analysis, was accomplished. Information on geometry was obtained using 3D optical scanning procedure. Material model was gathered using non-destructive mechanical testing and mimicked in a FEA software. For loading conditions the static structure analysys using FEM was accomplished. The critical poins in construction was found. Recognition of agreement about experimental and computational model was accomplished.

Leg prothesis
Bulva, Ondřej ; Harabiš, Vratislav (referee) ; Balogh, Jaroslav (advisor)
This thesis deals with the current state of development of active lower limb prostheses and focuses mainly on own design of active prostheses. The introduction deals with the anatomy of lower limb and briefly describes the walk cycle. In other chapters are summarized amputation techniques in the lower limb, followed by a description of the allocation of prostheses according to the level of amputation, which were described in earlier chapters. The thesis also deals with the division of prostheses according to the patient's activity level and briefly describes the structural differences in these individual cases. Chapter describing the actual development in the field of active prostheses initiates part dealing with the detailed description of the part of the prosthesis. The following chapters deal with the design and implementation of a prototype of active transfemoral prosthesis. The penultimate chapter deals with the software description of all parts of the prosthesis. This chapter is followed by an evaluation of the achieved results.

Prosthetic equipment after the disarticulation in knee joint
Lietavcová, Martina ; Šolc, Zdeněk (advisor) ; Půlpán, Rudolf (referee)
Title: Prosthetic equipment after the disarticulation in knee joint. Objectives: The aim of this bachelor thesis is to give the comprehensive overview of information about the problematics of disarticulation in knee joint and its possibilities in prosthetic equipment. Methods: This theoretical thesis is made by the form of literature overview. During its creation, there was used a method of collecting data out of professional literature, articles, magazines and other publications concentrating on this topic. For the verification of the gained information, there was used a method of informal interview with expert. Results: The purpose of this bachelor thesis is the summarization of the possibilities of prosthetic equipment after the knee disarticulation, which may serve as an educational material for the general public and students which are occupied in this problematic. Keywords: prosthetic of lower limb, disarticulation, amputation, amputation stump, rehabilitation

Case Study of Physiotherapy Treatment of a Patient with the Diagnosis Status Post Right Hip Disarticulation
Körnerová, Tereza ; Novotná, Irena (advisor) ; Voráčová, Helena (referee)
Title: Case Study of Physiotherapy Treatment of a Patient with the Diagnosis Status Post Right Hip Disarticulation. Summary: The main purpose of thesis is summary of teoretical findings about lower limb amputacion and processing of case study of the pacient with the hip disarticulation. The general part includes facts from anatomy, kineziology, amputations and prosthetics of lower limb. It pointes to great psychological, social and economical impact which should be dealt with. The special part consists of case history, inicial examination, short-term and long-term physiotherapy care about pacient after hip disarticulation. The therapeutic exercises are described in detail. Final inspection is compared with the result of the inicial examination and in the end of the thesis is evaluated the therapeutic effect. Keywords: amputacion, hip disarticulation, protetics, lower limb prothesis, rehabilitacion, physiotherapy, case study
