Alpha activity monitor
Kašpar, Blahoslav ; Sekora, Jiří (referee) ; Chmelař, Milan (advisor)
This work deals with problems of EEG biofeedback and possibilities of its use in therapy. The method of EEG biofeedback helps patients to achieve the state of relaxation. It is a noninvasive treatment modality. The paper also discussed the requirements for each component unit. The main point of a design and construction of Alpha activity monitor, a device implementing EEG biofeedback focused on sensing electrical activity of the brain, specifically alpha waves. Alpha activity is specific and their parameters are taken into account when selecting components and construction equipment. Custom feedback is then for the appearance of alpha activity mediated by the headphones in acoustic form. The work also includes design of electrical circuits and electrical diagram of the overall apparatus including a list of used parts. Electrical diagrams are formed in the EAGLE 6.1.0.

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 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...

Using biofeedback for patient with non-specific low back pain
Prokůpková, Eva ; Čakrt, Ondřej (advisor) ; Černý, Rudolf (referee)
The Diploma thesis titled "Using biofeedback for patients with non-specific low back pain" in theoretic part gives basic information about motor learning, biofeedback, low back pain and postural stability. In the research part, it deals with influence of postural stability- focused therapy (performed on Nintendo Wii Fit Plus device) on low back pain and postural stability. The work also deals with influence of added feedback on reduction low back pain, postural stability and realizing intrinsic feedback. We demonstrate that this therapy reduced low back pain but has no significant influence on postural stability. We also demonstrate that added feedback has positive effect on persistence of pain and affective part of the Short Form of McGill Pain Questionary, but it does not influence postural stability. On the contrary, absence of added feedback significantly influenced the postural stability. The added feedback does not influence awareness intrinsic feedback.

Holá, Irena ; Čakrt, Ondřej (advisor) ; Čada, Zdeněk (referee)
The thesis deals with the evaluation of the impact of preoperative application of gentamicin on vestibular compensations of patient after vestibular schwannoma surgery. The trial involved 32 patients with diagnosed vestibular schwannoma and hospitalized with the indicated for neurosurgical resection at the University Hospital Motol. Ototoxic gentamicin was transtympanically applied to ten of these patients two months before their surgery. After the surgery the patients underwent a rehabilitation program based on the visual biofeedback using the Homebalance system. To evaluate the vestibular compensation the subjective visual vertical measurement and the Dynamic Gait Index standardized walking test were used. In total, each patient performed three examinations: before the surgery, after the surgery and before the end of hospitalization. Statistical analysis of the measured data showed the statistically significant increase tilt of subjective visual vertical and the decrease in the overall score of Dynamic Gait Index after surgery. Reduction in the subjective visual vertical tilt and the overall score of Dynamic Gait Index after rehabilitation has not been proven to be statistically significant. Any statistically significant difference was found between the group of patients treated by gentamicin and...
