Feedback for active hand prosthesis
Trajlinek, Jan ; Sekora, Jiří (referee) ; Harabiš, Vratislav (advisor)
This thesis deals with the solution for feedback of active prostheses to ensure that it is as similar as possible to the biological somatosensory system, and at the same time to prevent any limitations to the patient and provide the patient with as much useful information about the sensual touch as possible. With regard to these factors, the system for the detection of forces acting on the limb and the subsequent transmission of this signal to the user´s limb is proposed. This system is designed particularly for an already constructed prosthesis manufactured by Ing. Štěpán Brázdil within the diploma thesis from 2020. The thesis describes the biological response, on which all substitutive and artificial responses are based on. The thesis then further describes these substitutive and artificial responses and aims to find solution, how the biological response can be more or less replaced.

Effect of foam rolling on mechano-nociceptive and vibrational sensation.
Novotná, Eliška ; Čech, Zdeněk (advisor) ; Demeková, Júlia (referee)
The thesis deals with the evaluation of the influence of foam rolling on selected parameters of somatosensory perception (pressure-algic threshold, vibrotactile sensation). The theoretical part discusses fascial tissue, summarizes the current knowledge of foam rolling and focuses on the mechanisms of pain and vibrotactile sensation. The research part consists of a randomized blind study on a group of 15 healthy probands (11 women, 4 men), which evaluates the effect of foam rolling. The effect is objectivized by pressure algometry and vibrametry on the m. rectus femoris and m. biceps femoris of both lower limbs (measured before and after therapy). The value of the pressure pain threshold (PPT) increased after foam rolling. Vibrotactile threshold (VT) was lower after foam rolling than before its use, which means that vibrotactile sensitivity was increased. The results show that these changes do not occur only in the interventioned m. rectus femoris, but some changes in parameters can be found in other muscles as well. Keywords fascial tissues, foam rolling, pressure algometry, pressure pain treshold, PPT, vibrametry, somatosensory system, nociception, diffuse noxious inhibitory control, DNIC

The effect of sensation disorders on upper limb function in patients after brain injury
Medková, Lia ; Angerová, Yvona (advisor) ; Rodová, Zuzana (referee)
OF DIPLOMA THESIS Name and surname: Bc. Lia Medková Thesis supervisor: MUDr. Yvona Angerová, Ph. D., MBA Referee: Title thesis: The effect of sensation disorders on upper limb function in patients after brain injury Abstract The aim of this thesis was to determine The effect of sensation disorders on upper limb function in patients after brain injury. Method: The research for this thesis involved non-experimental pre-research and quasiexperiments. The thesis' theoretical hypothesis was developed on the basis of previous studies that had looked at the effect of brain damage on patients' upper limb function. A total of twenty patients between the ages of 20 - 59 were selected to participate in the empirical study reported in this thesis. All participating patients had suffered damage to their cerebral cortex. The causes of their brain damage included strokes, trauma and tumor. The participants were divided into two groups of ten using the Nottingham Sensory Assessment. Participants with sensory disorders were allocated to the experimental group. Participants without sensory disorders were placed in the control group. The Jebsen-Taylor test was performed on all participants to assess their upper limb function after they had suffered brain damage. Results: Hypothesis thesis: Disorders of superficial,...

3D analysis of immediate effect on posture of shoe with postural insoles based on Rašev and with proceptor insoles PodoAktiv
Koukalová, Martina ; Rašev, Eugen (advisor) ; Pavlů, Dagmar (referee)
Title: 3D analysis of immediate effect on posture of shoe with postural insoles based on Rašev and with proceptor insoles PodoAktiv® Objectives: The thesis aims to show the immediate effect of application of custom-made insole on postural hold of chosen body segments and we would like to determine whether it is possible to use PodoAktiv® or insole based on Rašev to correct body posture. Methodology: In this thesis we examined 9 participants who agreed joining the study. We used the Balance®4D device made by Paromed company. The selected body segments were marked by white spheric stickers. To compare postural hold of selected body segments we examined the participants in altogether 4 situations. Barefoot stand, stand in shoes without insoles, stand in shoes with postural insoles based on Rašev and stand in shoes with proceptor insoles PodoAktiv®. Results: The results of this study show that there is a slight immeadiate effect of the custom- made insoles on postural hold of body segments. Larger effect was observed in the participants who already had a bad postural barefoot hold. Of all 6 parameters, the biggest effect was observed in the shift of overall body axis after application of PodoAktiv® insoles. Keywords: Shoe insoles, proprioceptors, somatosensory system, 3D static analysis, postural hold

Development of somatosensory system in the context of the postural - locomotion system and the as sessment possibilities
Hrušková, Adéla ; Zounková, Irena (advisor) ; Smolíková, Libuše (referee)
The aim of the work is to describe the somatosensory system function development in the context of postural- locomotion function in preschool age and to describe the possible assessment of this function in preschool children, on the basis of research. The theoretical chapters deal with the development of the somatosensory system and the postural- locomotion system, also with the physical development of the preschool child. The practical part presents the outcomes of the research, namely how the development and usage of somatosensory signals by central nervous system is influenced by growth of the preschool child's organism. Lastly, the work presents the possibilities how to assess the preschool child's somatosensory system in common physioterapeutic practice. A preschool child's case report is included.

Ševčíková, Lucie ; Čakrt, Ondřej (advisor) ; Pospíšilová, Mariana (referee)
Bachelor's thesis "Postural Stability in Patients with Cerebellar Ataxia" deals with the issue of postural stability related to patients with cerebellar lesion. The thesis summarizes the basic information ragarding the influence of cerebellum to the postural stability of the stance. In the experimental part of thesis, we assess the impact of deep foot massage and approximation of joints of lower limbs on the postural control measured with the force platform.

Local changes of selected somatesthetic parameters in response to stretching m. quadriceps fenoris
Vaňková, Karolína ; Čech, Zdeněk (advisor) ; Lepšíková, Magdaléna (referee)
Fascial tissues form a continuous whole-body three-dimensional network penetrating all parts of the human body. They include all fibrous connective tissue that significantly contributes both to themaintaining of the integrity of the organism and the functioning of body systems and the somesthetic perception.That is because of the facia is richly populated by proprioceptiveand mechanosensitive nociceptive nerve endings. Although the stretching is a routine method used in sports and rehabilitation, its exact mechanism of influence and effects on the body are not fully understood so far. Stretching exercises affect the mechanical state of the myofascial tissues and also the quality of the nociception and proprioception by alteration of their preload. There is evidence about some differences of the mechanical properties of the tissuesboth between thesexes and hypermobile individuals. The theses assesses the effect of static stretching m. QF on the somesthetic perception by measuring pressure pain threshold (PPT) using pressure algometry and the quality of propcioception bygoniometric measurement considering the interindividual variance in quality of the connective tissues. Our research includes testing of 29 healthy subjects (14 women and 15 men) and it has proved significant impact of the intervention on the...
