Assessing the influence of constitutional hypermobility on postural stability
Zadražilová, Tereza ; Smékal, David (advisor) ; Čakrt, Ondřej (referee)
The thesis "Judging the influence of constitutional hypermobility on postural stability" focuses on the problem of constitutional hypermobility (CH) and the influence of joint instability on stability mechanisms. The aim of the research was to find out whether there is a difference in stability mechanisms with tested subjects with CH and without it. Furthermore, the research focuses on the influence of mobility techniques on postural stability by the means of chosen tests carried out on Balance Master® System platform. The tested sample includes 14 women aged from 20 to 28, 7 women with constitutional hypermobility and 7 women as a control group. 6 tests were chosen for the measurement on Balance Master® platform. 2 static tests: modified Clinical Test of Sensory Interaction on Balance (mCTSIB), Unilateral Stance (US), and 4 dynamic tests: Limits of Stability (LOS), Rhytmic weight shift (RWS), Step Up Over (SUO) a Forward Lunge (FL). We compared the medians of output values of individual tests. It was assumed that subjects with KH would have significantly worse test results than the control group. Furthermore, it was supposed that the mobilization processes cause stability disturbance on the basis of cancellation of compensational , thus protective block in comparison with KS.

Ways to influence amateur's athletes postural stability
Fišer, Jan ; Zahálka, František (advisor) ; Nováková, Tereza (referee)
Title Ways to influence amateur s athletes postural stability Objectives The aim of this study is to describe the selected parameters of body composition and postural stability of the amateur s athletes (floorball players) group and to assess the efficiency of short-term intervention exercise based on senzomotor stimulation, acral coactivation therapy and plyometrics. Methods This work is a descriptive work, one part of it is the intervention. Two groups of amateur s athletes (floorball players) were examined during the study - intervention group(n = 16, average height = 178,23 cm (std 7,18), average weight = 80,04 (std 11,53), average age = 25,15 years (std3,31 )) and control group(n = 8, ave- rage height = 181,48 cm (std 5,59), average weight = 82,29 kg (std 11,20), average age = 27,07 let (2,68)). Each participant underwent the entrance measurement both on Footscan to evaluate the level of postural stability by selected parameters and on InBody 3.0 a Tanita to evaluate the level of body composition by selected parame- ters. Then the intervention group took part in the intervention exercise. After the six week intervention period underwent both groups the second measurement. The results of both measurements were evaluated, compared and statistically analyzed. Results The results showed great...

Function of Vestibular System in Patients after Cochlear Implantation
Bárta, Martin ; Čakrt, Ondřej (advisor) ; Jeřábek, Jaroslav (referee)
Theoretical part of the thesis summarizes state of art in the field of interaction of sound stimuli with the vestibular system and balance control. Further it summarizes the effect of cochlear implantation on the peripheral vestibular structures and on the stance stability. Cochlear implantation is effective way of hearing rehabilitation. Nevertheless surgery in the region of the inner ear results in reduction of function of the peripheral vestibular structures on the implanted side. The functional deficit of the peripheral vestibular system induced by the surgery is well tolerated by patients and quickly spontaneously subside. Sound available to the patients after implantation is one of the important modalities needed for balance control. In patients with balance deficit was found higher reliance on hearing when maintaining stable stance. Some sounds can reduce postural sway. Namely listening to the broadband noise (such as white and pink) results in reduction of postural sway. The balance control also relies on the ability to localize sound source. Information about position of sound source can be utilized as point of reference for driving balance reactions. Experimental part of the thesis quantifies changes in stance stability in patients with cochlear implants using stabilometry. The...

Comparison of static and dynamic stability after induction of vestibular stimulation in ice hockey players and healthy population
Kasala, Lukáš ; Levínská, Kateřina (advisor) ; Čakrt, Ondřej (referee)
In this study we found out whether professional ice hockey players have better static and dynamic stability after vestibular stimulation after 20 seconds of spinning on a rotary chair compared to normal healthy population. A total of 21 probands, 8 professional men players, 1 professional woman player and 12 men from the ordinary healthy population underwent testing. Probands passed a total of 8 tests, 4 tests without vestibular stimulation and the same tests after vestibular stimulation on a rotary chair. For testing on a stabilometric platform, we used the variants parallel stance barefoot on plate, parallel stance on a foam pad, parallel stance barefoot on plate with head movement to extension, parallel stance on a foam pad with head movement to extension. The rotation time on the chair was 20 seconds at a rate of approximately 1 Hz (20 turns ± 2), followed by a stability measurement time of 30 seconds. Our measured results showed that there is not signifficant difference in static and dynamic stability between ice hockey players and healthy population after induction of vestibular stimulation.

Ištoková, Lucie ; Kučerová, Klára (advisor) ; Čakrt, Ondřej (referee)
Bibliographic identification IŠTOKOVÁ, Lucie. The influence of cochlear implant on vestibular function in adult patients. Prague: Charles University, 2nd Faculty of Medicine, Department of Rehabilitation and Sports Medicine, 2020. 58 p., Appendices. Thesis supervisor Mgr. Klára Kučerová. Abstract Severe hearing loss is standardly treated by cochlear implantation. Considering the anatomical proximity and interconnection to the vestibulocochlear nerve, it is possible to influence vestibular functions. The aim of this diploma thesis is to evaluate the effect of unilateral cochlear implantation on postural stability and vestibular function in adult patients with severe hearing loss caused postlingually. Eleven patients aged 28-72 were examined the day before surgery, the day after surgery, and on average 25 days after surgery. The evaluation consisted of short-form Dizziness Handicap Inventory (DHI), Timed Up and Go testing (TUG), static stabilometry and the perception of the subjective visual vertical (SVV) static and dynamic. Significant deterioration of TUG and SVV was recorded particularly immediately after surgery. In dynamic SVV, especially, when the field of view rotated to the left. Considerable results in stabilometry were only when standing on a hard surface with eyes closed. Improvements in TUG, SVV...
