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.

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...

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...

Changes of trunk mobility in relation to postural stability
Kocourková, Monika ; Šorfová, Monika (advisor) ; Vláčilová, Ivana (referee)
Title: Changes of trunk mobility in relation to postural stability Objectives: The main aim of this work was to quantitatively observe segmental trunk mobility in 3D space during flexion of arm and create coupled pattern phenomena of particular spine segments. Additional aim was to verify the effect of modification of the measurements on movement performance and to relate the given movement of the arm and the segmental trunk mobility to changes in the load of the lower extremities. Methods: The measurement itself was performed on 23 asymptomatic males aged 20 - 30. In 3 modifications of the motion measurement - no load, with load and with load and hold with arm forward, probands performed 5 repetitions of right arm flexion in the sagittal plane. The motion was scanned by system Qualisys markers while standing on 2 Kistler stabilometric platforms. Results: In most probands, the segmental movement of the spine was repeatable. It was possible to compare it between probands and create coupled pattern phenomena of the spine. The increased arm load and hold with arm forward caused an increase in the deflections of the particular spine segments in sagittal plane. Furthermore, the increase in load has led to demonstrably greater load changes in the lower extremities. The link between the segmental trunk...

The assessment of the compensation of stabilometric parameters in patients after vestibular schwannoma surgery
Kozlová, Eva ; Čakrt, Ondřej (advisor) ; Hrubá, Silvie (referee)
In this thesis, we have been dealing with the evaluation of progressing of the postural stability in the patients after the operation of the vestibular schwannoma (VS). The stability was evaluated by means of stabilometric parameters (COP trajectory length, COP confidence ellipse area). We measured the development of the parameters before operation, immediately after resection and before the discharge. The set contained 17 patients (n = 17). The level of static importance we determined p ≤ 0,05. We found a statistically significant difference between the measurement before the operation and the measurement immediately after the operation (COP confidence ellipse area: p = 0,0183, COP trajectory length: p = 0,0355). On the other hand, the change in both parameters in the measurement before the discharge and the testing after the resection wasn't statistically significant (COP confidence ellipse area: p = 0,4081, COP trajectory length: p = 0,9991). Our next goal was to find out if the stability fault correlates with the disorder of function VOR. We testing the function of t-VOR by the subjective visual vertical (SVV) (n = 24), the function of the r-VOR by the dynamic visual acuity (DVA) (n = 28) and the caloric test (n = 21). We found a statistically significant correlation of both stabilometric...

Bibliographic identification Author's first name and surname: Bc. et Bc. Kateřina Levínská Title of the master thesis: Effect of various types of sensory and cognitive dual-tasking in high performance athlete's stance stability Department: Department of Rehabilitation and Sports Medicine, 2nd faculty of medicine, Charles University and FN Motol Supervisor: PhDr. Ondřej Čakrt, Ph.D. The year of presentation: 2017 Abstract: This study focused on the influence of various types of cognitive and sensory dual- tasking to the stability of stance of the elite floorball players, elite floorbal players with anterior cruciate ligament reconstruction and healthy controls. A total of forty probands were divided into 3 groups according to the sports activity and the history of ACL injuries. Volunteers underwent examination of bipedal and monopedal standing on a stabilometric platform using a foam pad. We chose three types of secondary task, which we tested first at probands in a sitting position. Subsequently, we combined them with a bipedal and monopedal stance on a foam mat. In secondary tests, latency of response and error rate were measured. Our results show that the combination of a postural challenging situation with a secondary task significantly more affects performance in the sensory-cognitive task than the...

Effectivness of vestibular stimulation in patients with postural stability disorder
Ševčíková, Lucie ; Čakrt, Ondřej (advisor) ; Bitnar, Petr (referee)
The diploma thesis summarizes physiology of vestibular system and disorders of vestibular system. In experimental part we observe the influence of vestibular stimulation on static postural stability. We achieve vestibular stimulation by active and repeated head and body movements. We measure the lenght of COP trajectory using stabilometry. We tested two groups of persons, 20 healthy persons aged 21 - 49 years and 6 patients with postural stability disorder from vestibular origin aged 40 - 76 years. The changes in lenght of trajectory COP after vestibular stimulation were not statistically significant in any group, but for each patient, there was a change in lenght of trajectory of COP. In patients, who have peripheral vestibular disorder, there was a reduction in lenght of trajectory of COP. Powered by TCPDF (www.tcpdf.org)
