Postoperative symptoms after vestibular schwannoma surgery and their impact on quality of life
Koutná, Sára ; Čakrt, Ondřej (advisor) ; Hrubá, Silvie (referee)
Vestibular schwannoma is one of the most common tumors found in a cerebellopontine angle. Despite tumor's benignity, there are many cases that are indicated for a surgical resection. Frequently postoperative symptoms described by patients and also by literature are hearing loss, vertigo, tinnitus and weakness or numbness of face. Our work wants to show also other factors which can be damaging for patient life. We talk about postoperative headache and anxiety or depression disorders. The aim of the study will be describe these symptoms, try to find the corelations between them and determine the impact on quality of life. In our survey, patients one year after vestibular schwannoma resection recieve convenient questionnaires to fill. The questionnaires will be focused on headache disability, anxiety and depression, vestibular dysfunction and perception of quality of life.

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...

The evaluation of gait and balance tests in patients after vestibular schwannoma surgery
Chejnovská, Lucie ; Čakrt, Ondřej (advisor) ; Hrubá, Silvie (referee)
The thesis deals with the evaluation of gait and balance tests in patients after vestibular schwannoma surgery. The experimental part focuses on the evaluation of dynamics of walking tests during hospitalization of patients diagnosed with vestibular schwannoma. The aim of the experimental part is also to analyze statistically significant correlations between measurable parameters of vestibulo-ocular reflex and walking tests and to evaluate the correlation between the subjective scale of fall fear and the objective assessment of walking and dynamic postural stability. A total of 28 patients aged 33 to 68 (14 men and 14 women) were incuded in the research with diagnosed vestibular schwannoma. Measurements were performed three times in patients (before surgery, after surgery and before the end of hospitalization). After the surgery, in addition to standard rehabilitation, training with visual biofeedback was included using the interactive Homebalance system. Gait and balance assessments were performed throug the tests Timed Up and Go, Four Step Square Test and Functional Gait Assessment. Examinations were complemented by a questionnaire of subjective assessment of fear of falling Falls Efficacy Scale. Statistical analysis showed a significant correlation coefficient in the correlation of Four Step...
