Methods for the evaluation of postural stability
Nevěčná, Leona ; Janoušek, Oto (referee) ; Koťová, Markéta (advisor)
This study deals with methods for evaluation of postural stability. The main problem of posturography is lack of standardization in measurement and evaluation. There are presented some parameters affecting postural stability that are often taken into account. Those are parameters that might be changed while measuring, for example standing position, sampling duration or visual control. And others that are altered when evaluating is taking place, variability of those parameters, is much greater. Measurement protocol taking into account the most promising parameters was put together based on literary search. Changes in COP of ten subjects were measured with Wii Balance Board, according to the proposed measurement protocol. The data acquired from a particular subject were used to count values of parameters used in evaluation. After that the values were statistically analyzed. To compare each parameter, trajectory with good results according to other literature was chosen to pose as a reference. Final result is comparison firstly between importance of changes in parameters of measuring and secondly between success of detection of those changes of separate parameters.

Čubanová, Slavka ; Kotolová, Veronika ; Hýbl, Jan ; Volf, Petr ; Hejda, Jan ; Sokol, Marek ; Leová, Lydie ; Kutílek, Patrik
Posturografie je obecný název pro techniky používané k hodnocení posturální stability těla. Vědecko výzkumný tým biomechanika a asistivních technologii KZOOO FBMI ČVUT se dlouhodobě zabývá optimalizací ochranných pomůcek pro IZS. Nejdůležitější funkcí těchto pomůcek je ochrana nositele před zraněním. Pro použití v praxi je však důležité i zajistit určitý komfort při nošení. Tyto pomůcky ve formě například balistické vesty, helmy, ochranných obleků pro hasiče atd. často stěžují samotný pohyb, jsou však pro vykonání některých úkolů nezbytné a nejde se bez nich obejít. V rámci ergonomické optimalizace těchto ochranných pomůcek jsme se zaměřili na měření posturální stability uživatelů ochranných vest. Zajímá nás, jestli a jak ovlivňuje nošení ochranných pomůcek posturální stabilitu členů IZS a jakým způsobem můžeme zvýšit komfort při nošení právě těchto nezbytných ochranných pomůcek.

Hip joint stability and injury prevention in sport
ČERVENÝ, Daniel
The aim of this thesis is to describe, how does the strengthening of stabilization hip muscles affect whole postural stability and at the same time how does it affect standing on one leg for athletes in different sport. The theoretical part of the thesis summarizes information about anatomy a kinesiology of hip joint. Includes important angles measured in the age of hip joint development. Besides is described postural stability, and stability function in the various levels on human body with all the participated muscles while hip joint stabilization. In the practical part is research of three probands doing cross country skiing, athletics, and triathlon. Measurement was consisting of posturography, kinesiological analysis and by performing special tests focused on hip joint. All the patients received paper of exercises to do at home with addiction of individual exercises for patient's pathology. At the end of the therapy was compared all the information from the first and second measurement and done conclusion. The resulting effect was positive, because in most patients was improvement of secondary performing test measuring stability, placement of COG and lateral stability of hip joint. Another result was subjective evaluation in the way of dialogue. Patients evaluated the therapy as a positive for them and wanted to continue in cooperation.

Possibilities of influencing postural stability in sports training of judokas
VACOVÁ, Anna
This thesis deals with postural stability in the sports training of judokas and the possible ways by which it can be influenced. The aim of the bachelor's thesis was to include a kinesiotherapy intervention using elements for improving postural stability in the sports training of judokas and to evaluate its effectiveness, while another aim was to measure postural stability of standing on one lower limb. The theoretical part summarizes information about the postural system, postural functions, central motor control, judo and describes the methods that inspired the exercise unit. In the practical part, there are case studies of four probands from the sports club TJ Sokol Centropen Dačice. The key part was to perform an examination on the NeuroCom posturography device. Part of the thesis is a sample of selected elements that were used during the research. The results of the examination show that these young judokas have faulty posture and muscle shortening, as well as poor postural functions and insufficient stabilizing function of the lower limb. When comparing the entrance and exit examination, which followed the end of the three-month research, there was no significant difference. However, there was an improvement in certain aspects, which may be related to the inclusion of the given elements. This work could serve as educational material for judo coaches and an inspiration for creating a training plan.

Changes in selected postural stability tests in hemiparetic patients after botulinum toxin application
ZEMANOVÁ, Lucie
The subject of this bachelor thesis is to compare changes in selected clinical and posturographic tests of postural stability, before and after application of botulinum toxin A to selected lower limb muscles in patients with spastic hemiparesis. The theoretical part deals with the introduction of general information related to posture, such as clinical tests of postural stability, their significance and use, as well as the issue of falls. The next part concerns spastic paresis, its origin, causes, consequences and also clinical scales that evaluate spasticity. The last theoretical part summarize the treatment options of spastic paresis. The practical part describes in detail the kinesiological analyzes of patients and the results of clinical and posturographic tests. Functional Reach Test, Timed Up and Go and Mini BESTest were selected from the clinical trials. Within the posturography, the Weight Bearing Squat test, Modified CTSIB and Limits of Stability were selected. The overall results of this research were not entirely clear, as the individual tests focus on different aspects of postural stability. Some tests were better after botulinum toxin application and some of them before botulinum toxin application. However, impairment of postural stability was in relation to the hemiparetic half of the body. Research has also shown that vision is a key aspect of postural stability in hemiparetic patients. This research could serve as inspiration in the treatment of postural stability not only in hemiparetics, but also in stability disorders in general.

Vestibular and postural biomarkers in spinocerebellar ataxias and peripheral vestibular lesions
Danková, Michaela ; Jeřábek, Jaroslav (advisor) ; Roth, Jan (referee) ; Sivák, Štefan (referee)
Vestibular and postural biomarkers in spinocerebellar ataxias and peripheral vestibular lesions Abstract Vestibular dysfunction can be a part of clinical impairment in spinocerebellar ataxias. Together with cerebellar symptoms, it can lead to imbalance and also to impairment of dynamic visual acuity (DVA) in these patients. The aim of the work was to objectify the involvement of the vestibulo-ocular reflex in patients with SCA using modern diagnostic methods. At first the innovative method of video head impulse test (vHIT) was introduced in patients after vestibular schwannoma surgery, in whom a clearly defined vestibular impairment is present. We investigated DVA in SCA patients, the degree of the DVA impairment correlated proportionally with the impairment of vestibular function measured by vHIT. The best predictive values for DVA impairment were obtained by using a model that combined impairment of vestibulo-ocular reflex measured by vHIT and degree of cerebellar dysfunction according to SARA (scale for assessment and rating of ataxia). The research also aimed at the verification of postural stability disorders in patients with SCA using posturography. Standard posturographic parameters (area, sway path and mean velocity of Centre of foot Pressure - CoP) did not allow to distinguish between individual...
