Case study of use of a motorized exoskeleton as an orthotic aid in the case of post-traumatic paraplegia
Herrmann, Norbert ; Neuwirthová, Svatava (advisor) ; Pavlů, Dagmar (referee)
Title: Case study of use of a motorized exoskeleton as an orthotic aid in the case of post-traumatic paraplegia. Objectives: Assessment of the effectiveness of using a motorized orthosis to improve motor functions of a patient diagnosed with paraplegia due to a spinal cord injury. Methods: The theoretical part introduces the issue of post-traumatic spinal cord injury and related paraplegia and follows a description of the function of the motorized exoskeleton (and comparable devices) as an orthotic device. The practical part describes the case of a patient with post-traumatic paraplegia of the lower limbs, which includes anamnesis, diagnosis, planned therapies and especially the course of the therapy with the exoskeleton, including its settings, application, walking training and data collection. Results: There was a remarkable progress in the patient's gait achievement during the therapy with the use of the exoskeleton. These advances were based on the data recorded by the software during the individual therapies with the exoskeleton. In addition to gait therapy with an exoskeleton, the patient underwent other supportive therapies, leading to an overall significant improvement in the patient's physical condition and motor skills. After completing the prescribed therapies with the exoskeleton, the...

Sublethal effects of the insecticides neonicotinoids on migration abilities of spiders
Přibáňová, Gabriela ; Řezáč, Milan (advisor) ; Korenko, Stanislav (referee)
The purpose for using pesticides is to kill organisms that cause damage (so-called pests) on various crops and thus prevent possible crop losses. Their side effect is a negative impact on non-target organisms. The presented diploma thesis is focused on the effect of neonicotinoids on invertebrates particularly on spiders. Its main goal was to document their influence on behavioral parameters influencing dispersal abilities such as locomotion and tendency to spread by wind (so-called ballooning). The diploma thesis compares the influence of neonicotinoids on model species, Pardosa lugubris (Walckenaer, 1802) and Phylloneta impressa (L. Koch, 1881) with different modes of prey hunting and compares the influence on adult and nymphal stages. Pesticides Actara® 25 WG, Biscaya® 240 OD, Confidor® 200 OD and Mospilan® 20 SP were applied to the spiders under laboratory conditions and their effect was tested at different concentrations and different methods of application. The biggest impact on spiders had Confidor. It clearly had the most significant negative effect on mobility and a tendency to spider wind propagation. The lethal effects were caused by neonicotinoids in nymphal individuals Pardosa lugubris, especially Confidor (even 100% mortality for tarsal application). During an experiment studying the...

Effects of a neuroactive steroid on motor skills of young laboratory rat.
Košťálová, Tereza ; Mareš, Pavel (advisor) ; Valeš, Karel (referee)
The steroid substances with effect on nervous tissue are plenteously studied in last years. Their biggest benefits are especially anticonvulsant and anxiolytic effects. This thesis inspects the influence of newly discovered neruactive steroid pregnanolone pyroglutamate synthesized in The Institute of Organic Chemistry and Biochemistry of the Czech Academy of Science (IOCB CAS), which offer potential opportunity of a new therapy of epilepsy from actual pharmacokinetic results. Our goal was to detect, if this substance has any negative effects on locomotor skills of young laboratory rats. In theoretical part of the thesis the development of laboratory rat is briefly descibed, especially its motor skills and sensory functions in comparison with human. The process of the experiments and choice of especially motor skill tests are described in Metogology part. The results of experiment and its comparation with the effect of other neuromediators are introduced and discussed in the practical part of this thesis. There were no serious effects of pregnanolonepyroglutamate applied repeatedly in perinatal period on motor performance. Acute administration of the highest dose of PPG to 12-day-old rat pups resulted in prolongation of time in surface righting and negative geotxis tests. This data are positive for...

Design and implementation of control program for mobile robot platform Turtlebot3 Burger
Filip, Jakub ; Lacko, Branislav (referee) ; Parák, Roman (advisor)
The aim of the bachelor thesis is the design and implementation of a control program for the mobile robotic platform TurtleBot3 Burger. The theoretical part of the bachelor's thesis defines the issue of mobile robotics, with a closer look at the various possibilities of locomotion, including examples from industrial practice. The TurtleBot3 mobile robot series belongs to the robotic platforms distributed by ROBOTIS, where their main feature is compatibility with the Robotic Operating System (ROS). The core of this system is licensed under the BSD, which guarantees open source code. The integration of ROS with the TurtleBot3 Burger model provides freely accessible robust libraries, which form the basis for understanding the control of a differentially controlled robot through ROS. In the practical part, the assembly and configuration of the robotic kit TurtleBot3 Burger is performed, including the introduction of key functionalities of this mobile platform, and the design of your own solution. The conclusion contains the justification of the mentioned proposal and the output after its implementation on a real robot.

skeletal adaptations for bipedal locomotion and its possible effect on knee joint injuries
Karban, Tomáš ; Kautzner, Jakub (advisor) ; Hora, Martin (referee)
The subject of this Bachelor's Thesis is the change of locomotor pattern in human ancestors, which led to habitual bipedalism and associated skeletal adaptations, that changed functions of specific body parts. The main focus is on adaptations that adjusted the function of the knee joint, either directly by changing the anatomical structure in the knee area, or indirectly, for example, by increasing the tension in muscles or tendons due to weight transfer to the lower limb. Given adaptations are then a criterion for evaluating possible influence on typical knee injuries in modern human. Key words Bipedalism, locomotion, human, chimpanzee, injury, knee joint, knee, adaptation, evolution, anatomy

Muscle force during walking: effect of skeletal morphology
Tomášová, Kateřina ; Hora, Martin (advisor) ; Sedlak, Petr (referee)
The muscle force determines the energy costs of locomotion and the loading of the musculoskeletal system. As the body size increases, the muscle force increases too. The observed less joint flexion in larger individuals could be a moderating mechanism to reduce muscle force when walking. To date, there is a lack of knowledge about the effect of body size and joint angles on muscle force. The aim of this study was to investigate how body size affects muscle force in the stance phase of walking and whether larger individuals can effectively compensate for the increase in muscle force through postural changes. We acquired kinematic, kinetic and electromyographic data for 19 men during normal walking and carrying additional 20 % of body weight. We estimated muscle force using the method of musculoskeletal modeling. We emploeyd the multiple linear regression to asses independent effect of body mass, lower limb length, biiliac breadth and joint flexion angle on total (iF) and maximum (maxF) lower limb muscle force. The body mass had a great positive effect on the gluteus medius muscle force (maxF and iF) but did not affect the iliopsoas muscle force (maxF and iF) nor the vasti muscles force (iF). The lower limb length had a positive effect on the gluteus maximus muscle force (maxF) and a negative effect...

Sublethal effects of the insecticides neonicotinoids on spider's migration and predatory abilities
Přibáňová, Gabriela ; Řezáč, Milan (advisor) ; Korenko, Stanislav (referee)
This research deals with impacts of pesticide substances on spider populations. In this case pesticides of the neonicotinoids classes were tested. Specific neonicotinoids were applied to different of spiders which were collected in various localities and at some stage of development - nymph, adult or subadult individuals. The diploma thesis analyzes and the documents the effects of neonicotinoids to spiders. The results show that some pesticides can have a significant negative effect to locomotion, predation, ballooning, drop or to spiders mortality. Keywords: spider, arthropod, pesticides, insecticides, neonicotinoids, sublethal effects, mortality, EthoVision XT, locomotion, drop, ballooning, predation, Philodromus, Oedothorax, Pardosa, Xerolycosa, Phylloneta
