Influence of six-week training intervention with visual feedback on the NeuroCom SMART Equitest System on the postural stability of football players
Filip, David ; Vomáčková, Helena (advisor) ; Kokštejn, Jakub (referee)
Title: Influence of six-week training intervention with visual feedback on the NeuroCom SMART Equitest System on the postural stability of football players Objectives: The first aim of this diploma thesis is to find out the effect of the six-week training intervention with visual feedback performed on the NeuroCom SMART EquiTest on the postural stability of football players. The second aim of this diploma thesis is to correlate the Maximum Excursion parameter from the Limits of Stability test on the NeuroCom with the Star Excursion Balance Test score performed on The MAT. Methods: This research involved 20 football players in the age from 19 to 30 (age average = 23,85; SD = 2,79), who belong to the adult category. First, soccer players underwent initial postural stability measurements using seven tests on the NeuroCom SMART EquiTest and excursion distance measurements when performing the Star Excursion Balance Test (SEBT) on the MAT. Subsequently, they were randomly divided into two groups: control (n=10) and experimental (n=10). The experimental group underwent a six-week training intervention with visual feedback using training protocols on the NeuroCom SMART EquiTest. After the training intervention of the experimental group, postural stability was measured again on a NeuroCom SMART EquiTest and...

Visual constrains in badminton serve
Ďurčo, Dominik ; Carboch, Jan (advisor) ; Petružela, Jan (referee)
Title: Visual constrains in badminton serve Objectives: Main goal of this bachleor's theses was to examine whether and to what extent does the visual feedback influences short badminton serve, whether the accuracy and success rate will change. Methods: Data were obtained experimentally, later evaluated by the method of indirect observation - video analysis. Ten players were tested. Each player was subjected to four tests. The first serve test was with occlusion, the player's vision was occluded at the moment of contact of the shuttlecock with the racket using the occlusion glasses that the players wore. The second and third tests were performed under normal conditions. The last test was the same as the first test with occlusion. Results: By comparing the average distances of the shuttlecock impact points between the short backhand serve tests in badminton, a statistically significant effect of visual feedback p = 0.04 on the accuracy of short serve was demonstrated. In the occlusion tests, the average distance between the line and the point of impact of the shuttlecock was 32.5 ± 23.9 cm and under normal conditions 27.7 ± 20.8 cm. The difference between number of fouls under two conditions was only 1.5%, with more foul attempts being recorded in the tests under normal conditions. Keywords:...

The role of optical function and its influence to the posture
Terčová, Simona ; Oplatková, Lenka (advisor) ; Veselý, Viktor (referee)
This bachelor thesis deals with the optical function as one of the multisensory modalities in postural control. The theoretical part concerns the anatomy, physiology and pathophysiology of the visual system and their relationship to postural functions. It also includes a further indefinite weakening of neurophysiological principles, influencing other sensory perceptions and motor manifestations with the visually impaired, who belong to group with reduced postural control. The work describes the examination methods and training options for visual perception and its impact on postural control. These applications are applied in the practical sections in the case report of visually impaired patients, in whom the influence of the individual examination unit on postural function was investigated. For the assessment were used the Rehawalk pressure platform and the clinical test of dynamic postural stability Star-Excoursion Balance Test.

The assessment of the compensation of stabilometric parameters in patients after vestibular schwannoma surgery
Kozlová, Eva ; Čakrt, Ondřej (advisor) ; Hrubá, Silvie (referee)
In this thesis, we have been dealing with the evaluation of progressing of the postural stability in the patients after the operation of the vestibular schwannoma (VS). The stability was evaluated by means of stabilometric parameters (COP trajectory length, COP confidence ellipse area). We measured the development of the parameters before operation, immediately after resection and before the discharge. The set contained 17 patients (n = 17). The level of static importance we determined p ≤ 0,05. We found a statistically significant difference between the measurement before the operation and the measurement immediately after the operation (COP confidence ellipse area: p = 0,0183, COP trajectory length: p = 0,0355). On the other hand, the change in both parameters in the measurement before the discharge and the testing after the resection wasn't statistically significant (COP confidence ellipse area: p = 0,4081, COP trajectory length: p = 0,9991). Our next goal was to find out if the stability fault correlates with the disorder of function VOR. We testing the function of t-VOR by the subjective visual vertical (SVV) (n = 24), the function of the r-VOR by the dynamic visual acuity (DVA) (n = 28) and the caloric test (n = 21). We found a statistically significant correlation of both stabilometric...

Compensation of balance disoder in time in patients after vestibular schwannana resection
Hajná, Barbora ; Čakrt, Ondřej (advisor) ; Chovanec, Martin (referee)
Introduction: Disorders of balance and dizziness are characteristic symptoms in patients after vestibular schwannoma surgery and often have a negative impact on their quality of life. This thesis deals with impairment of postural stability particularly in patients at the long time period after surgery. The aim of this study is to observe the longitudinal development of vestibular compensation from acute postoperative period to time of several years after surgery. Another aim is to evaluate the short-term effect of vestibular rehabilitation in a long time period after surgical treatment, and to compare the results of measuring the subjective visual vertical, posturography, score of the Dizziness Handicap Inventory questionnaire, age and tumor size in these patients. Methods: Examined group consisted of 10 patients after resection of vestibular schwannoma (mean age 41.4 ± 12.1 years; 2 women and 8 men). All patients underwent intensive rehabilitation program in the acute phase after surgery. 7 patients did exercise with visual feedback, and 3 patients had conventional rehabilitation without visual feedback. In long time period after surgery all patients underwent one exercise unit with visual feedback. Patients underwent computerized posturography examination using force platform Balance Master® in...

Clinical findings and diagnosis of vestibular lesions in patiens with vestibular schwannomem
Kalitová, Petra ; Langmeier, Miloš (advisor) ; Šlapák, Ivo (referee) ; Kozler, Petr (referee)
Summary: The aim of our study was diagnosis and rehabilitation of vestibular loss in patients with vestibular schwannoma. In the first part we focused on analysis of a group of patients before resection of vestibular schwannoma, mainly on evaluation of gain of posturography and on optimalisation of diagnostic algorithm of vestibular pathology. Throughout the second experiment, we studied if rehabilitation of postural gait with visual biofeedback will speed up vestibular compensation in patients after resection of vestibular schwannoma. The group consisted of 44 patients, who underwent surgical removal of vestibular schwannoma. Before surgery each patient underwent clinical vestibular examination, electronystagmographic recordings and posturography. In the second part of the study 17 patients from previous group were chosen. These patients underwent rehabilitation and rehabilitation with biofeedback. For evaluation was used independent samples T-test and cross-tabulation. A great number of variables were reduced by factor analysis. For statistical analysis of the group with rehabilitation was used nonparametric Wilcoxon signed rank test. Statistical analysis revealed that the most typical parameter for vestibular pathology is the time of the step quick turn test, which is a part of posturography. We proved...
