Novotný, Petr ; Vilímek, Miloslav (advisor) ; Horák, Zdeněk (referee)
Title: Nordic walking - analysis of senior walking Aims: This thesis aims to make a kinematic and kinetic analysis of gait and NW in elderly using Qualisys and Kistler. Afterwards, it also aims to compare the selected parameters with each other and, based on the results, to objectify the effect of NW on the gait of the elderly. Methods: The theoretical part of this thesis was processed using books and electronic sources obtained from online databases (PubMed, Medline, and Google Scholar). The research part was done in the form of an experiment. Fifteen women aged between 65 and 83 years (mean age 74) who regularly practiced Nordic walking under professional guidance participated in the research. These women were measured while walking and NW. A 3D kinematic analysis of walking and NW was performed using the Qualisys Motion Capture camera system. Ground reaction forces were measured using Kistler force plates placed in the captured kinematic analysis path. Data from these instruments was processed in Qualisys Track Manager and Microsoft Office Excel. Selected gait parameters that were analyzed included stride length, double-step length, gait speed, stride cadence, standing phase duration, lateral pelvic deviation, hip flexion and extension, knee joint flexion, dorsal and plantar flexion of the ankle...

Effect of walking and exercise with elastic resistance on selected functional parameters in the elderly
Palčinská, Renáta ; Pavlů, Dagmar (advisor) ; Malá, Jitka (referee)
Title: Effect of walking and elastic resistence exercise on selected functional parameters in the elderly Objectives: The aim of this thesis was to evaluate the effect of walking and elastic resistance exercise on selected parameters in the elderly population. Methods: The target group was healthy adults aged 60-80 years capable of independent walking. Subjects were randomly divided into three groups. The intervention of the first group consisted of elastic resistance exercise and controlled walking twice a week/ 1 hour for one month. The intervention of the second group consisted of walking twice a week/ 40 minutes, and the control group performed only the normal activities of the day. The respiratory parameters - vital capacity and FEV1, functional parameters - six-minute walking test and Sit to Stand test, and the distance of the acromion from the bed were evaluated. The measured values were statistically and graphically processed. Results: By comparing the individual tests of the intervention groups of walking with resistance exercise and walking alone, a higher benefit of the combination of exercises was found in almost all parameters. Keywords: FEV1, FVC, 6MWT, Sit to Stand test, elderly, measurement acromion-bed, resistance exercise, walking

Vliv fyzioterapie na kondici, koordinaci a posturální stabilitu u osob s Parkinsonovou chorobou.
DOMASOVÁ, Martina
Parkinson's disease is a neurodegenerative progressive disease that cannot be cured even today. However, it is possible to influence and slow down its progress to a certain extent. Symptomatic treatment is used to suppress the disease, of which physiotherapy is an integral part. In Parkinson's disease, physiotherapy can suppress the symptoms of this disease, improve the patient's condition and significantly help the patient maintain a higher quality of life for a longer period of time. The first aim of the bachelor thesis was "To draw attention to the importance of physiotherapy in a patient with Parkinson's disease". The second aim was "To map the possibilities of physiotherapy in a patient with Parkinson's disease". Both of these goals were fulfilled and described in the theoretical part in subchapter 1.8.3. In addition, the practical part of this thesis refers to the first one, where it is possible to see the changes in the condition of the patient with Parkinson's that occur when applying group exercise to his regimen. The third aim was "To design an exercise that would lead to the improvement of the condition of the patient with Parkinson's". This goal is dealt with in the practical part of this thesis. Based on the knowledge gained in the theoretical part, an exercise unit was created, which was then applied for two months to a group of seven probands. To evaluate its effect on the condition of patients, input and output kinesiological analyses were compared, including clinical tests to examine fitness, coordination and postural stability (FTSST, TUG, BBS, Pull Test, Push & Release Test).

Person Identification Based on Locomotion
Pražák, Ondřej ; Richter, Miloslav (referee) ; Horák, Karel (advisor)
This paper deals with study of human movement and using that in identification. In the first part of my work are explained characteristics of human movement and factors which take effect on these characteristics. Practical part is dealing with design of program which is solving mentioned problems. The input of program is created by video sequence with lateral movement of human. The program is finding coordinates of lower limbs joints. From this coordinates are created locomotion characteristics used for human identification. Matching of time behaviors is based on correlation.

Person's identification by means of bipedal locomotion
Krzyžanek, Jakub ; Richter, Miloslav (referee) ; Horák, Karel (advisor)
The aim of this thesis is to recognize a walking person in a sequence of images by defining his or her reference points to compare the course of their movement and then to identify the scanned person. Methods „k-means“ and „mean shift“ are used to obtain the silhouette of the person. However “environment model estimation” method is used here before those mentioned above. It is a type of a difference method and it helps to specify the scanning area and shortens the time of segmentation. During the search for the reference points the thesis focuses on three areas: the centre of the head and both ankle joints. Those points are later determined on the previous image sequence and compared with the real locations of the centre of the head and ankle joints marked by the user. The thesis also focuses on comparing the movement courses of those points and tries to identify the people whose walks are being scanned. Problematic situations which occurred during the whole process are analyzed in the end. The result of the thesis is an algorithm which can locate a moving person in an image sequence (video) and determine the reference points (centre of the head and ankles) to compare them and identify the scanned person.

Walking as alternative source of electrical energy
Smilek, Jan ; Hejč, Tomáš (referee) ; Hadaš, Zdeněk (advisor)
This thesis deals with problematics of using the Energy Harvesting principles for generating power from the human walking. Own acceleration measurement during walking was made on various locations of human body to provide data for self-developed MATLAB/Simulink energy balance script. The script clearly sets the possibilities and limits of vibration generator used in this application. Conclusions of the energy balance were used to specify requirements for development of vibration generator and few possible conceptions, working on frequencies close to 2 Hz and acceleration amplitudes 0,3 g, were presented, or simulated.

Implementaion of the controllers of a mobile walking robot
Krajíček, Lukáš ; Věchet, Stanislav (referee) ; Ondroušek, Vít (advisor)
This diploma thesis deals with design and implementation of the controllers of a mobile walking robot. The advantage of these controllers are their kinematics and geometrics independent representation, which allow to use them for different robot types and tasks. In this thesis the contact controller is designed, which minimizes residual forces and torques at the robot's center of gravity, and thereby stabilize robot's body. Next the thesis deals with a posture controller, which maximizes a heuristic posture measure to optimize posture of robot body. Because of this optimization, legs are moved away from their limits and therefore they have more working space for next move. Implementation of the chosen solution is made on the robot's MATLAB mathematical model. Controllers are composed into a control basis, that allows to solve general control tasks by simultaneous combination of contained controllers. The algorithm was created for that simultaneous activation and its operation was explained on flow charts.
