The influence of walking speed on the ability to maintain a straight direction after rotational stimulation of labyrinth
Bradáčová, Andrea ; Čakrt, Ondřej (advisor) ; Jeřábek, Jaroslav (referee)
The theoretical part focuses on vestibular system - the formation and role of vestibular information in the control of bipedal locomotion, and processes issues of gait control with respect to walking speed and the use of sensory feedback. The experimental part deals with the effect of rotational stimulation of labyrinth on the ability to maintain straight walking direction with the exclusion of visual control at various speeds - slow walking, fast walking and running. Two groups were tested - younger group aged 21 - 30 years (29 people) and older group aged 41 - 55 years (15 people). The difference between deviations from a straight direction before stimulation (with the exclusion of visual control) and after stimulation appeared to be significant (p < 0.05) for slow walking, fast walking and running, but only in the younger group. In the younger group there was also a statistically significant difference between deviation for slow walking after rotational stimulation and deviations for fast walking and running after stimulation. In the older group there were statistically insignificant differences between deviations before and after stimulation and between various speeds. Younger and older group differed statistically significantly in response to rotational stimulation at slow walking. The results...

Testing of the mobility and dynamic ba lance of seniors
Bradáčová, Andrea ; Čakrt, Ondřej (advisor) ; Ptáková, Karolína (referee)
The theoretical part deals with problems of old age and aging and its impact on balance, mobility and walking alone. It summarizes the knowledge about execution, use and reference and other values of the Timed Up and Go, clinical test used in senior population mostly in testing mobility, walking, dynamic balance and risk of falling. The research part contains an experiment, where two groups of people - group of seniors aged 66 - 87 years and control group aged 43 - 60 years - were examined by the TUG test and its variant with a cognitive task. The results of this work show, that some seniors achieved a higher TUG score than healthy population of foreign studies. In a group of seniors TUG was able to distinguish different level of functional mobility and it's determinants. In combination with assessment of the quality of performance and cognitive task, which causes decrease of score and performance in the elderly, can serve as a fast and available screening functional status and mobility.
