Hynková, Simona ; Grünerová Lippertová, Marcela (advisor) ; Zahálka, František (referee)
This bachelor's thesis focuses on the rehabilitation of patients after the Covid-19 disease. The patients were part of a rehabilitation programme at the clinic of rehabilitation at University Hospital Královské Vinohrady, where they underwent intensive therapy for up to 2-3 weeks. The aim of this bachelor's thesis was to determine the efficacy of the therapy in all patients, but also the differences between patients according to the diseases they had associated. Methods: For 13 selected patients after undergoing covid-19, the data were collected data on their health using anamnestic data in the medical documentation and Covid-19 Mental Health Questionaire (CoPaQ) questionnaire. Using the data, there were selected the most frequently occurring diseases and complications by which the effectiveness of the therapy was evaluated. Motor skills, self-sufficiency and shortness of breath were assessed in the clinic according to standardised tests, which are as follows: saturation, a Berg balance scale, a Barthel index, a Borg scale, a modified functional self-sufficiency test, and an Expanded Barthel Index, which was not included in the specific results because it barely changed. Results: A Wilcoxon paired t-test was performed in assessing the effectiveness of rehabilitation in total, rather than...

Michalcová, Eliška ; Zahálka, František (advisor) ; Heller, Jan (referee)
Title: The effect of kinesiotaping for flat foot correction in association with selected parameters of gait for a specific group of people Objectives: The primary objective of this experiment was to determine whether and to what extent the application of kinesio tape to flat foot (utilising a functional correction technique) can influence the positioning of the specific segments of the body and thereby implement change to walking stereotype. Methods: Biomechanical measurement of the gait of eleven specifically selected people with the clinical symptoms of flat foot was implemented. First we recorded measurements prior to the intervention and then again, subsequent to the application of kinesio tape for a defined period. Probands retained the tape in place for the following four days and then the measuring was repeated both prior and subsequent to the removal of the tape. To determine any potential changes to the statics, initially the measuring of the postural stability prior to the intervention was first implemented in the experiment and subsequently again when the kinesio tape was removed after it had been worn for four days. This measurement was carried out using the Footscan apparatus (RSscan International, Belgium) and any potential differences in six variant modes of posture were determined....

Šípková, Petra ; Malý, Tomáš (advisor) ; Zahálka, František (referee)
Title: Strength of knee extensors and flexors as a determinant in performance of speed abilities in youth Objectives: To find out whetherthere is a correlation between the strength of the knee flexors and extensors and the performance in speed tests in a selected age group Methods: There was a laboratory and outdoor testing carried out with a group of 42 students. The results were processed in tables and graphs, the arithmetic mean and the standard deviation functions were used Results: The tests showed that the more powerful the knee flexors and extensors are the better the performance in speed tests is. The hypothesis proved right, there is a strong relation between the knee flexors and extensor strength and a speed performance. The flexors scored higher in the importance for a speed performance than the extensors Keywords: Speed, strength, testing, youth, performance
