Biofeedback in patients with balance disorders
Čakrt, Ondřej ; Jeřábek, Jaroslav (advisor) ; Syka, Josef (referee) ; Hlavačka, František (referee)
This dissertation is providing evidence that rehabilitation with biofeedback improves postural stability in patients with poor balance. We used two methods of biofeedback during the rehabilitation of the patient groups, visual control and electrotactile stimulation of the tongue. The thesis is based on the body of five scientific publications. The introduction is explaining how postural stability is controlled and how this is assessed by posturografic examination. Discussed also is neurorehabilitation using biofeedback, in patients with poor balance. Throughout the first experiment, we studied the effect of rehabilitation using visual feedback in patients during the early postoperative period after resection of vestibular schwannoma. The results showed stability adaptation is accelerated, using visual biofeedback in patients who have early postoperative rehabilitation, when compared to patients who did not use biofeedback during the postoperative rehabilitation. In the second experiment, we focused on assessing the subjective visual vertical in patients with defined postural deformity - idiopathic scoliosis. Our results showed that patients with idiopathic scoliosis (IS) have an abnormal perception of subjective visual vertical when compared to age matched healthy individuals. This finding supports the...

Perception of subjective visual vertical
Radvanská, Edita ; Čakrt, Ondřej (advisor) ; Kučerová, Klára (referee)
Postural balance system is a multisensory-organized complex using afference of exteroceptors, enteroceptors, proprioceptors and the visual and the vestibular system. The utriculus and the sacculus are otolith organs placed in the vestibular labyrinth and they are capable of recognizing the direction of gravity. Their function is crucial for keeping postural stability during stand and walk. The ability to recognize the geophysical vertical is failing if the vestibular system is impaired. There are the subjective visual vertical (SVV), the subjective postural vertical (SPV) and the subjective haptic vertical (SHV) which can be tested in humans. This study is interested in SVV, its pathophysiology and measuring. We are comparing the accuracy of measurement of SVV by the Bucket method and a mobile application Visual Vertical in healthy subjects in our experiment.

Influence of defferent kinds of running shoes on stability and risk of injury in long - distance runners
Krchová, Zuzana ; Čakrt, Ondřej (advisor) ; Doubková, Lucie (referee)
The main problems concerning birth of running injuries is their unclear ethiopathogenesis and high frequency. Injuries are often lined with forces affected on tread-down which have to be defused by running shoes. There are also opinions that currently used footwear can cause injuries on the contrary. This work explores impact of particular types of running shoes for influencing of stability. Methods: There are compared two groups of runners: minimalists and classic runners. Their stability is examined with help of posturography in three versions: barefoot, classic and minimalistic footwear. Thereafter there is analyzed relation among stability, used footwear, training usage and frequency of injuries. Results: Minimalists and classic runners have the same stability while they are barefoot. Usage of footwear does not cause significant deterioration of stability in any of groups. Nevertheless most of runners subjectively evaluate the variant of testing barefoot as the simplest. There is more frequent occurence of flat foot among classic runners in comparison with minimalists. Flat foot increases risk of formation injuries, on the contrary, regular compensation motion activity decreases this risk.

Electrotactile sensory substitution in patients with degenerative cerebellar ataxia
Svojítková, Tereza ; Čakrt, Ondřej (advisor) ; Paulasová - Schwabová, Jaroslava (referee)
Introduction: Biofeedback based on sensory substitution is a new method to treat patients with postural disorders. BrainPort provides tongue electrotactile stimulation. This innovative technique was developed for vestibular dysfunction of peripheral origin. Primarily for patients who had no benefits from conventional rehabilitation. Tongue electrotactile stimulation seems to be useful for central vestibula dysfunction as well. We are dealing with effect of BrainPort in therapy of degenerative cerebellar ataxia. We are interested in whether the effects persist for one month after the rehabilitation program. Methods: The methods are applied in 6 patients with degenerative cerebellar ataxia, verified by clinical testing, posturography, and genetic testing or verification of cerebellar lesions by MRI. Patients underwent an 12-day intensive rehabilitation program with BrainPort. Treatment was carried out 2 times a day. Patients were learning appropriate postural corrections to maintain signal in the middle of the tongue. To assess the effect of therapy we used posturography, standardized clinical tests - BESTest, Dynamic Gait Index (DGI) and standardized questionnaires - The Activities-Specific Balance Confidence Scale (ABC) and Dizzines Inventroy Handicap (DHI). The examination was performed before...

Running shoe as a possible cause of injuries in endurance runners . from the perspective of a physiotherapist
Krchová, Zuzana ; Smolíková, Libuše (advisor) ; Čakrt, Ondřej (referee)
This work collects knowledge on running shoes and its potential impact on injuries in endurance runners in the theoretical part. There is a sought link between the running-related injuries, usually used running shoes and foot-strike technique. Then there are described the most common running related injuries and kinesiology of running. The practical part includes a study in the form of a questionnaire, which was attended by 383 runners. This research presents the results of the effect of footwear on running mechanics and the formation of overuse injury in endurance runners. The data obtained demonstrate injury in 48% of runners in the last 2 years. The most common site of injury is the knee joint. Runners usually resolve these problems having a rest. Endurance runners who buy frequently new shoes are more injured than runners who run in older shoes. Rearfoot-striking is associated with knee- pain, but it is not a higher risk of injury.

Slackline as a therapeutic possibility to influence postural stability
Komárková, Klára ; Čakrt, Ondřej (advisor) ; Pospíšilová, Mariana (referee)
Objectives: To summarize knowledge about a control of posture, a balance training and a testing on balance platform. I investigate in experimental part of my thesis if slackline training will affect stabilography and differences in quantitative parameters will be found in a training group or a control group. Hypothesis: A specific slackline training positively affects stability which was measured in posturographic selected tests done by the training group. Methods: We test postural stability in control (10 persons) and training (10 persons) group in selected tests of stability. We used a balance platform for testing. The data were statistically analysed. Results: 4 weeks of intense slackline training result in improvement of postural control. That is support by the data of stabilometric examination. The results were just below statistical significance (p > 0.05). Conclusion: The results testify that slacklining can improve postural control in healthy subjects. The results were on the boundary of statistical significance in our intervention group.

Gitschinská, Eva ; Čakrt, Ondřej (advisor) ; Paulasová - Schwabová, Jaroslava (referee)
Diploma the 'is deals wi th the research of effect of biofeedback in the form of electrotactile stimulation of tongue in the patients with balance disorders eaused by the cerebellar lesion. For the therapeutic program 4 patients with cerebellar ataxia at the age of38 - 74 years were chosen. Subjects have partieipated in the therapeutic program with the application of biofeedback, they were training postural stability while visual control was excluded and they were using electrotacti le signal on the tongue for orientation. I used neurological tests BESTest and Dynamic Oait Index, questionnaire The Activities- Specific Balance Confidence (ABC) Scale, Dizziness I Tandicap Inventory (D ll) a Visual Analogue Scale (VAS), and examination by stati posturography for evaluation of postural stability in the patients. I supposed that therapy by biofeedback in the form of electrotactile stimulation of tongue improves postural stability in the patients with balance disorders caused by cerebellar lesion.
