Perception of subjective visual vertical
Radvanská, Edita ; Čakrt, Ondřej (advisor) ; Kučerová, Klára (referee)
Postural balance system is a multisensory-organized complex using afference of exteroceptors, enteroceptors, proprioceptors and the visual and the vestibular system. The utriculus and the sacculus are otolith organs placed in the vestibular labyrinth and they are capable of recognizing the direction of gravity. Their function is crucial for keeping postural stability during stand and walk. The ability to recognize the geophysical vertical is failing if the vestibular system is impaired. There are the subjective visual vertical (SVV), the subjective postural vertical (SPV) and the subjective haptic vertical (SHV) which can be tested in humans. This study is interested in SVV, its pathophysiology and measuring. We are comparing the accuracy of measurement of SVV by the Bucket method and a mobile application Visual Vertical in healthy subjects in our experiment.

Side difference in morphology of the medial humeral epicondyle in context of the ulnar neuropathy of elbow.
Radvanská, Edita ; Mezian, Kamal (advisor) ; Jačisko, Jakub (referee)
The ulnar neuropathy of the elbow (UNE) is the second most common compression neuropathy in the upper extremity. The studies of impact of bone morphology on the origin of the ulnar neuropathy are inconsistent. According to the recently published retrospective analysis of 880 cases of the cubital tunnel syndrome, the incidence of the ulnar neuropathy is more often on the left side, independent of handedness. The theoretical part of this thesis contains a summary of recent literature with an emphasis on the etiology, basics of diagnostics, treatment and rehabilitation of the UNE. The experimental part is made of the measurement of ten parameters of humerus bones. The aim of this experiment was to decide whether some of these measures were different compared to the other side. There were statistically significant differences in 4 of 9 crucial parameters, where the right side was bigger than the left side, therefore we believe the influence of bone morphology on the origin of the UNE cannot be excluded. The results may help towards a better understanding of the etiopathogenesis of the origin of the UNE and therefore be a valuable starting point for other studies of prevention, diagnosis and therapy of the UNE.
