Gantar, Sebastjan ; Pavlů, Dagmar (advisor) ; Vláčilová, Ivana (referee)
Title: Differences in postural activity during quiet standing when breathing abdominally. Aim and purpose: Aim of this study was to examine the effects of abdominal breathing on selected muscles and stability during quiet standing to find empirical evidence if it can reduce the strain and change the activity pattern, which erect standing demands from the muscles. Methods and materials: This thesis begins with an introduction to theoretical part in which we gathered all the already existing and written information needed to form the knowledge base for our experiment. Continuing in 9th chapter, methodology and experiment procedure are described where we measured muscle activity using surface EMG and to monitor changes in stability we used force- plate for posturography where only linear parameters were acquired. Both devices were used simultaneously while the subject was in quiet stance for a period of 90 seconds. Results: Results shown decrease in most of the muscles, with a higher increase in body sway in medio- lateral than in antero-posterior direction. Signal didn't change to a more distinct wave-like pattern of rhythmic oscillations, as we had thought it would. Keywords: Posture, quiet standing, abdominal breathing, diaphragm, system interrelation, EMG, posturography

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...

Mrázková, Lucie ; Zahálka, František (advisor) ; Strnad, Pavel (referee)
Title: Evaluation of selected postural stability parameters of diabetic patients Objectives: The main objective of this thesis is to describe the level of postural stability using the selected parameters in diabetes mellitus type 2 and to try to find a relationship between the severity of disease. We also want to compare the level of postural stability for such an illness with respect to the values of selected parameters of the healthy population. Methods: It is a descriptive study. The theoretical part was the basis of the processing problems of diabetes mellitus, with a focus on neuropathy. After that we evaluate data of selected parameters of postural stability in diabetes mellitus type 2. The second part involves the experiment, which refers to the evaluation of this issue in terms of posturographic analysis. A group of 30 type 2 diabetic patients were divided according to their diabetologist disease severity into 4 groups. A control group of healthy subjects included a sample of 7 probands. The patient group was composed of 18 men and 12 women, whose average age was 62.63 ± 15.55 years, average weight 91.17 ± 19.97 kg, who were subjected to measurement using a pressure plate FootScan (RScan International, Belgium). Results: We managed to prove, that subjects with diabetic neuropathy have...

The relationship between postural stability and physical activities
Gryc, Tomáš ; Zahálka, František (advisor) ; Janura, Miroslav (referee) ; Vavák, Miroslav (referee)
In the study "The relationship between postural stability and physical activities", we focused on determining the level of postural stability and the possibility of influencing by appropriate means of exercise intervention in people with increased physical activity and persons with physical limitations. Persons with increased physical activity were top players and players competing in various sports (football, handball, volleyball, golf) and those with physical limitations, patients suffering from diseases that have a negative impact on postural stability (Friedrich's ataxia, autosomal dominant spinocerebellar ataxia, Charlot-Marie- Tooth). Upright posture in stance and movement is a fundamental prerequisite for human bipedal locomotion. Postural stability is the ability to maintain an upright posture, which advises the motor and coordination skills, and its meaning is close to equilibrium abilities. Maintaining an upright posture is ensured by muscle activity, which is controlled by the central nervous system based on information from internal and external environment. Control of postural stability is the primary prerequisite for successful movement and as such it can be developed on the basis of appropriate physical activities. All methods of measuring static and dynamic postural stability can be...

The effekct of one training of postural stability in patiens with spinocerebellar ataxia
Filipovičová, Jana ; Pospíšilová, Mariana (advisor) ; Jevič, Filip (referee)
We followed the immediate effect of sensorimotor training on postural stability in patients with spinocerebellar ataxia (SCA). We have tried to explain the possible mechanisms of adaptation to change COP, motor learning and neuroplasticity in the field of neurodegenerative changes in the cerebellum. Research Methods: A total of 10 patients with spinocerebellar ataxia (6 men, 4 women) aged 34-71 years, with an average disease duration of 11.6 years participated in the measurement of postural stability. First, we measured the patients with SCA before and after a 15-minute sensorimotor-training exercise, then this group underwent another day of the same measurement without sensorimotor training. As a second control group of 10 healthy subjects served a similar age, who also underwent sensorimotor training. Then we compared the results of posturographic measurement. Results: In the group of SCA patients, sensorimotor training was found significantly lower values in the monitored parameters LENGTH (t stat = 3,537731 > t krit = 2,262157), VELOCITY (t stat = 3,537731 > t krit = 2,262157) and energy to sustain COP (t stat = 2,715085 > t krit = 2,262157), measured on a foam pad with eyes closed. Measurement without making sensorimotor training produced no significant improvement in the results of monitored...

The effect of kinesiotaping on postural control of stance
Havlová, Michaela ; Bitnar, Petr (advisor) ; Čech, Zdeněk (referee)
Postural stability is necessary for all human activities. Management od postural control is provided especially by central nervous system. For management are essential afferent information from vestibular, visual and somatosensory system. Modification of any of these inputs could have influence postural stability. Changes of exteroceptive perception can be achieved by the application of kinesio tape. Kinesiotaping is currently very popular therapeutic method, which is attributed to the wide range of effects. In the theoretical part of this thesis are described these effects, including the results of scientific studies that are engaged in verify the effects. Experimental part of this thesis was focused on the objectification of any changes of postural stability after application of kinesio tape on dorsal and ventral side of the trunk in healthy individuals without injury or other disorders. For the examination were used two tests of Balance Master® System, the modified clinical test of sensory interaction on balance and the test limits of stability. The results were satistically evaluated at the level α = 0.05. Due to kinesio tape were observed no siginificant changes in the mean sway velocity of center of gravity. There were also found no significant changes of parameters that evaluate the transmission of...
