This study is a qualitative analysis and a quantitative analysis of all peripheral biofeedback client data files of the University of North Texas Biofeedback Research and Training Laboratory since its establishment in 1991 and through the year of 2002. The purpose of this study is to evaluate the clinical and educational efficacy of the BRTL. Clients' electromyography and temperature measures, self-report of homework relaxation exercises and progress, and the pre- and post-Stress Signal Checklist were reviewed and analyzed. In regard to clinical efficacy, results indicate statistically significant changes in both temperature training and muscle tension training as a whole group. When divided into subtypes based on the clients' primary presenting problem, findings indicate statistical significance in chronic pain, tension headache, and temporomandibular jaw pain on temperature training, and show statistical significance in chronic pain, tension headache, hypertension, migraine headache, stress, and temporomandibular jaw pain on muscle tension training. When analyzing the Stress Signal Checklist, only 25% of clients had complete information on both pre- and post-Stress Signal Checklist. For these 25%, 87.5% reported symptoms decreased. When reviewing the clients' self-reported progress in therapist's session notes, there is no procedure for computing a treatment success to failure ratio due to the inconsistency of therapists in recording clients' statements. This study also identifies three basic biofeedback learning curves that show how people learn self-regulation skills in biofeedback therapy: 1) steady state and trainable (low variability), 2) phasic state and trainable (high variability), and 3) phasic state and low trainable (high variability).

Title: The use of biofeedback in physical therapy Objectives: The aim of this thesis is to summarize the accessible literary sources mapping the area of use of biofeedback in physical therapy and forms of its use. Furthermore, it aims to make a research and evaluate the effect of biofeedback therapy of woman urinary incontinence and neurofeedback therapy with children with Attention Deficit Hyperactivity Disorder (ADHD syndrome). Methods: This thesis is a descriptive analysis based on a literature review. The first part includes theoretical background dealing with the description, principle of operation and the possibilities of influence the therapy using biofeedback. The next chapter focuses on different areas of use of biofeedback in physical therapy and identifies the different forms of use. Subsequent research contains a presentation of studies, their comparison and critically evaluation of the effect of therapy using biofeedback for selected diagnoses. Results: Based on 69 found studies were clearly mapped using various forms of biofeedback in physical therapy. From the research findings which involved a total of 24 studies with the corresponding criteria, it was found that the method of biofeedback has a positive effect on the treatment of urinary incontinence in women. However, compared with...

The aim of this work is describe common methods of biological feedback therapy that is used to treat some psychosomatic diseases. Subsequently, the description is focused on minimal brain dysfunction treatment by the help of EEG biofeedback. Properties and technical requirements for this therapy are concretized. The last part of this thesis is dedicated to the design and realization of practical software tool for EEG biofeedback therapy which is made in LabView 7.1. The M535 acquisition unit and NI USB-6221 measuring device are used for hardware solution.
