Veselá, Cindy ; Mézl, Martin (referee) ; Hesko, Branislav (advisor)
This master’s thesis focuses on real-time detection of activity in electromyographic signal for reaction time measurement. For patients motivation there was designed and implemented therapeutic car game controlled throught the muscle activity. In this thesis were used three different algorithms for muscles activity detection in EMG signal. The best accuracy of this three methods has designed artificial network with U-Net hierarchy, which is used to segment samples into two categories - samples of signal with activity and samples representing calm. Accuracy of this method is 97 %. Later there were examined differences between groups of probands, different stimulus and the changes of reaction time over time.

Jileček, Jan ; Černocký, Jan (referee) ; Szőke, Igor (advisor)
This thesis aims to implement methods for recording EEG data obtained with the neural activity sensor OpenBCI Ultracortex IV headset. It also describes neurofeedback, methods of obtaining data from the motor cortex for further analysis and takes a look at the machine learning algorithms best suited for the presented problem. Multiple training and testing datasets are created, as well as a tool for recording the brain activity of a headset-wearing test subject, which is being visually presented with cognitive challenges on the screen in front of him. A neurofeedback demo app has been developed, presented and later used for calibration of new test subjects. Next part is data analysis, which aims to discriminate the left and right hand movement intention signatures in the brain motor cortex. Multiple classification methods are used and their utility reviewed.

EEG Biofeedback Human Brain - Computer Interface
Kněžík, Jan ; Kořenek, Jan (referee) ; Marušinec, Jaromír (advisor)
This master thesis dwells on EEGbiofeedback (also called Neurofeedback) interface of human brain and the computer and its concrete realization in Java programming language. This system is founded on the basis of the computer, which is accomplishing biological feedback (biofeedback) and the electroencephalography (EEG) by helping that state's scanning of user's brain is realized. By this way is possible to practise the human brain effectively to achieve better concentration, the elimination of sleeping and learning deficiency. Hereafter is the suggestion of direction control of computer mouse by EEG device incorporated, which makes it possible for the man to regulate the direction of the cursor's movement on the screen by the frequency of brain's oscillation. The motivation for solution of this problem is the effort to help to handicapped people to communicate with surrounding world. The introduction of this paper contains the basic facts about human brain, electroencephalography and EEG biofeedback. The following chapters dwell on the specification of claims to developed application, its suggestion and description of actual realization. The final part relates to the BCI (Brain-Computer Interface) systems and suggestion of computer's control by EEGappliance with evaluation of attained results.

Effect of biofeedback on stability, coordination and activation of the patients after spine stabilisation with the use of Hunova Movendo posturographic device
Získalová, Karolína ; Sládková, Petra (advisor) ; Malá, Michaela (referee)
6 ABSTRACT Title: Effect of biofeedback on stability, coordination and activation of patients after spi- nal stabilization using Hunova Movendo posturographic device Aims: The aim of this thesis was to introduce the Hunova Movendo posturographic de- vice and to validate its benefits in increasing stability by comparing outcome measures. The secondary aim was to evaluate the therapy from the probands' perspective. Methods. First, all selected probands underwent an initial interview and an initial postural stability examination using the Hunova Movendo device, which measured changes in body position values. The training intervention with visual feedback was conducted for a total of six weeks, specifically every Monday, Wednesday and Friday. In the third week of training, a follow-up examination was conducted to assess the improvement or deteri- oration of the results, and also to motivate all probands. At the end of the six-week inter- vention, an exit examination was conducted and probands were given a five-question subjective questionnaire to complete. The effectiveness of the treatment was compared through the entry and exit examination data from the first and last week of the interven- tion. Results: At the end of the six-week program using proprioceptive training with visual feedback on the Hunova...

The use of the OhmTrak device in self-treatment of patients with back pain
Tyburcová, Marie ; Kobesová, Alena (advisor) ; Jačisko, Jakub (referee)
Introduction: Impaired trunk stabilization is a frequent cause of chronic low back pain (CLBP). Trunk stabilization training can reduce back pain. Aim: To determine the effect of the OhmTrak (OT) trunk stabilization training device following Dynamic Neuromuscular Stabilization (DNS) principles in patients with CLBP. Methods: A single-blind randomized clinical trial. The investigator did not know to which group the participant belonged. 20 patients with CLBP were randomly divided into 2 groups. 10 patients included in the experimental group underwent six-week DNS training focusing on optimal trunk stabilization. The participants had a treatment session with a physiotherapist once a week. Experimental group patients were educated in self- treatment with the OT device which they performed for 15 minutes 5 times a week. The control group patients (n=10) underwent the same rehabilitation program of the same duration and frequency including the self-treatment. Control group participants performed self-treatment without the OT device. Before the start and at the end of the 6 weeks therapy program the ability to activate the abdominal wall was assessed using DNS Brace device in all participants from both groups. All patients from both groups completed the Oswestry Disability Index (ODI) questionnaire at...

The use of biofeedback for stability training in patients with degenerative cerebellar disease
Stránská, Lenka ; Čakrt, Ondřej (advisor) ; Jeřábek, Jaroslav (referee)
The graduation thesis deals with the issue of balance disorders due to a cerebellar damage. It deals in detail with the treatment of patients suffering from degenerative cerebellar ataxia and with the use of biofeedback technologies as means of postural stability treatment. The aim of practical part of this work was to investigate the effectiveness of therapy using biofeedback for patients suffering from progressive ataxia due to cerebellar neurodegeneration. The research sample consisted of 8 patients. The patients underwent a total of 18 therapy sessions within a twelve-day rehabilitative program. The therapy contained a training of stability in various positions with the elimination of visual control. A device provided an additive information about head sways for the patients via a tongue electrotactile stimulation. The effects were assessed by means of posturography, functional clinical tests (BESTest, Dynamic Gait Index) and questionnaires (Activities-specific Balance Confidence Scale, Dizziness Handicap Inventory). Three assessments were performed: immediately before, immediately after, and 30 days after the rehabilitative program. A statistical analysis of the data showed significant improvement in all observed parameters. In addition, there was no loss of the benefits in the interval of 30...

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...
