Kinematic analysis dinamic neuromuscular stabilization tests in people with low back pain.
Burešová, Vendula ; Valouchová, Petra (advisor) ; Kobesová, Alena (referee)
The main target of this thesis was to detect objective changes in the implementation of four postural locomotor tests DNS and during walking. The movements were recorded using the optical MoCap - the kinematic analysis Qualisys. The particular interest of the investigation was to determine the current stabilization of the spine system in individual subjects aged 25 to 55 years, which was documented by means of the angular deflection of each segment, the flat segment deviation or the shift of the marker in a coordinate system. The measurement results were compared between ten individuals with LBP and ten persons without any difficulty who were placed into the control group. The data were collected using the software QTM and Visual3D and subsequently were statistically processed. A statistically significant difference was observed during walking when comparing the angular deflection of the pelvis to the chest at the rotation and lateroflexion (ř). The significant difference of the pelvis shift toward the chest during flexion and rotation (ř) was showed in a deep squat test, but the difference was not confirmed in lateroflexion (ř). Furthermore, no statistical difference of the lateral deflection of the same segment (pelvis or chest) (cm) in patients with LBP compared to all subjects during the...

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.

Biofeedback using 3D scanners
Vačkářová, Klára ; Koťová, Markéta (referee) ; Žalud, Luděk (advisor)
This bachelor thesis focuses on the matter of the Microsoft Kinect sensor application within biomedical field. In the first theoretical part of the thesis general knowledge of sensors are mentioned; Microsoft Kinect is described thoroughly. The second part deals with the practical realisation of the program, which with help of visual biofeedback informs patients, whether they perform given movement properly or not. For this purpose three exercises were chosen. In the final part the methodology of realized measurements is described and as well as the measurement evaluation.

Animation Library Focused on Skeletal Animations
Dokoupil, Petr ; Přibyl, Jaroslav (referee) ; Štancl, Vít (advisor)
This thesis proposes an architecture of animation engine flexible enough to support large scale of animation algorithms with unified approach to each one of them. One of the major goals of the engine is to support creation of very complex animation seqences with high degree of animation execution control. The main animation technique used in the engine is skeletal animation and some variants of this technique are already implemented within, but it was never meant to be skeletal animation only engine and is designed that way.

Kinematic analysis of movement of cyclist with transtibial prosthesis.
Stoklásek, Pavel ; Mazůrek, Ivan (referee) ; Paloušek, David (advisor)
This work is aiming to the area of biomechanics and deals with the experimental finding of appropriate kinematic ratios of crank mechanism on racing bicycle and transtibial prosthesis of racing cyclists with an assessment of kinematic ratios depending on the overall athletic performance. The primary aim of the work is investigation of the impact of inappropriate existing kinematic ratios of leg prosthesis and crank mechanism on the kinematics and dynamics of top athlete. The work presents experiments that proposes find out appropriate kinematic ratio of the length of kinematic members and possibility to improve overall athletic performance. The measurement is supplemented about cycling analysis of racer realized via cameras tracking system and measuring muscle activity by EMG. The work also includes a description of impact of various factors on cycling.

Use of Motion Capture in Animation
Urazajeva, Regina ; Bubeníček, Jan (advisor) ; Truhlář, Filip (referee)
This bachelor thesis describes different techniques and application procedures of motion capture technology. It aims to cover individual steps leading from preparation through creation to editing and finalization of a project which uses the mocap technology. The main objective and contribution of the thesis is pointing out some possible difficulties which may occur while using a very complex process of capturing the human motion, and outlining possible means of preventing such problems.

Aplikace metod optické analýzy při zkoušení nábytku
Štábl, Jakub
This thesis deals with the use of digital image analysis during the chair testing. The thesis aim is to show and compare different analytic programs and two optical methods of measurement. Selected optical analysis are Digital Image Correlation and Motion Capture. These non-contact measurement methods are used during the chair testing, specifically static test of the seat and backrest. The measured values are statistically evaluated and the results of different methods and softwares are compared. The chair testing follows relevant standards.

Ovládání počítače pomocí gest
Tyksová, Lucie
This diploma thesis deals with controlling computers by gestures. It contains a description of motion capture and available technologies, a more detailed description of the Microsoft Kinect sensor and a summary of available libraries for developing applications controlled by Kinect. Part of this thesis is also a list of projects from various areas that are working with Kinect. The output of this thesis is an application controllable by natural hand gestures, to allow common tasks such as selecting elements, browsing through images, etc. Data from the Kinect sensor are processed through the Microsoft Kinect SDK. The application is implemented in C#.
