Pilný, Petr ; Pánek, David (advisor) ; Stupková, Michaela (referee)
Title: Problematics of kinetosis origin in virtual neurorehabilitation Aim: The aim of this diploma thesis is to acquaint the reader with theoretical background of the origin of cybersickness during the exposure of the user to virtual reality, describe the mental and physical effects and therapeutical use of virtual reality in various diagnoses. Experimental part of this thesis is focused on evaluating the rate of cybersickness occurrence during the therapy in various diagnoses and the influence of secondary factors on the amount of cybersickness. Methods: This diploma thesis is processed in the form of a literary review. The PubMed, Scopus and Web of Science databeses were used to search for studies. Total of 500 titles were indentified, this number decreased to 438 after removing the duplicates. After reading the abstracts, another 395 titles were removed. Out of 43 titles, remaining to be assessed in the fulltext form, 29 another titles were removed. Final number of titles, included in this literary review, is 14 titles, which met the critereria for inclusion. Results: Out of the 14 studies, included in the experimental part of this research and meeting the inclusion critera, 7 out of 14 groups total had the highest Simulator Sickness Questionnaire - Disorientation (SSQD) subscale value in...

The influence of virtual reality on stabilization functions of patients after cerebrovascular accident with neglect syndrome
Sedláček, Jakub ; Pánek, David (advisor) ; Pavlů, Dagmar (referee)
Title: The influence of virtual reality on stabilization functions of patients after cerebrovascular accident with neglect syndrome. Objectives: The objective of this thesis was to clarify whether postural stability of patients after cerebrovascular accident with neglect syndrome significantly worsen as an after-effect of virtual reality exposure in comparison with healthy probands and patients after cerebrovascular accident without neglect syndrome. Methods: 28 probands took part in this research, specifically 10 patients after cerebrovascular accident with neglect syndrome, 6 patients after cerebrovascular accident without neglect syndrome, and 12 healthy probands. All patients had been tested with Catherine Bergego Scale to evaluate neglect syndrome before the measurement of postural stability itself. That measurement consisted of probands being tested with Timed Up and Go test and a part of Berg Balance Scale. Afterwards, they took 10 minutes of immersive virtual reality game. Immediately after that Timed Up and Go test and Berg Balance Scale were repeated. The data were processed with MySQL database using a HeidiSQL program. Results: This research suggests that after exposure to virtual reality, there is no difference in changes of postural stability of patients with neglect syndrome in...

The usage of virtual reality in therapy of patients with neglect syndrome with consideration of a cybersickness risk
Macháčková, Tereza ; Pánek, David (advisor) ; Pavlů, Dagmar (referee)
Title: The usage of virtual reality in therapy of patients with neglect syndrome with consideration of a cybersickness risk. Objective: To find out if stroke patients with neglect syndrome tend to have higher risk of gaining cybersickness after using virtual reality compared to stroke patients without neglect syndrome and healthy population. Also, to find out if the severity of neglect syndrome has correlation with the severity of gained cybersickness. Afterwards to evaluate the trend of making games in virtual reality for treating neglect syndrome with consideration of a cybersickness risk. Methods: The experiment participants played game in virtual reality developed for treating neglect syndrome for ten minutes. During the game participants were seated and were playing using head movements. A HTC VIVE console was used to deliver the virtual reality game. Participants were divided into 3 groups: the group Zdraví (n = 12) without neurological impairment, the group CMP (n = 6) for stroke patients without neglect syndrome and the group Neglect (n = 10) for stroke patients with neglect syndrome (KF-NAP ≥ 1). Each proband had to fill Sickness Simulator Questionnaire which was used to detect cybersickness before and after playing the game in virtual reality. Collecting and sorting of the data was done...
