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...

Title: The assesment of selected strength and stability parameters of an ankle plantar and dorsal flexion in slackliners. Objectives: To assess the relation between level of stability the dorsiflexion and the plantar flexion strength in slackliners. Methods: The research sample was composed of two groups - slackliners (9 person) and balanced control group (9 person) selected from physically active population. Probands were tested on the Flamingo test on the pressure plate, the test of the dorsiflexion and plantar flexion strenght on an isokinetic dynamometer. Slackliners underwent extra range of motions elements on the slackline. The level of stability was assessed by using the centre of pressure and the physical design of individual elements on the slackline. Power was assessed by using the peak torque at 30 ř and 120 ř. Results: Slackliners achieve bigger relative strength in the plantar angular velocity of rotation of 30 ř in both limbs than the control group (left: 1.51 ± 0.31 vs. 1.20 ± 0.30 Nm.kg-1 , p <0.05 , η2 = 0.21, right: 1.55 ± 0.34 vs. 1.21 ± 0.34 Nm.kg-1 , p <0.05, η2 = 0.22). The results of other parameters (postural stability, isokinetic power at the ankle angular velocity of 120 ř.s-1 and the time course of force) between the two groups did not differ significantly. Conclusion:...

Name: Influence of a rupture and reconstruction of an anterior cruciate ligament on the postural activity of an individual Aim: The aim of my thesis is to find out whether a rupture and the following rupture recinstruction of an anterior cruciate ligament has an influence on the postural activity of an individual namely after a longer period ( at least one year) from the undergone operation. Methods: The thesis has been worked out by a form of an analytical comparative study where it deals with measuring of two groups of probands - healthy and those after anterior cruciate ligament operation. The postural behaviour of individuals was tested after deflection by impact of a pendulum at a free standing position with and without visual control and also when standing on one leg. Results: The results of the measuring denote that when a person after anterior cruciate ligament rupture and following rupture recinstruction is deflected by an external impact while standing on both legs he/she will rather rely on the leg without surgery but the side difference will not be very distinctive. This fact will not change much even without visual control. While standing on one leg though the individual after surgery will have a more serious problem to stabilize his/her position (the period of time to stabilize will...

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)

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...

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...

vi Abstract Title: Evaluation of postural stability among deaf adults Objectives: The purpose of this diploma thesis was to compare the postural stability between the deaf and the normal hearing adults, and to find out if the statistically significant difference in measured parameters does exist. Methods: 102 subjects at the age of 20-45 years participated in this study. The experimental group consisted of 35 deaf adult subjects with congenital or early childhood deafness. The control group has been made by 67 normal hearing adult subjects. The postural stability was objectively evaluated by Footscan, the pressure measuring plate. Nine tests were passed, duration of each test was 30 seconds. The total travelled way (TTW) expressing the total path the centre of acting pressure travelled during the test and the Romberg ratio, which is the ratio of TTW values under the condition of closed and open eyes, were selected as indicators of postural stability. T-test was used to assess the statistical significance of the differences between the group of deaf adults and normal hearing group. To estimate the influence of individual characteristics of the subjects (evaluating the data from the questionnaires) to their postural stability, the ordinary least squares estimator was used. Results: The experimental group was...
