New Research on Biofeedback







Evaluation of Clinical Biofeedback


Book Description

This comprehensive survey will be useful for anyone who seriously wants to learn more about the current therapeutic status of biofeedback-therapists, physicians considering a referral, well-educated prospective patients, teachers, students, and research workers. But readers with different needs should use it in different ways. For a quick overview of a large field, one should tum to the Introduction and Summary and Conclusions sections. The reader interested in a specific disease should look for the proper section in the Table of Contents and then tum to the overall summary at the end of that section and also the briefer summaries that are given in the last paragraph of many subsections, whenever sufficient data are available. The reader who wants more information should read the entire chapter. The serious student or research worker, for whom the book will be most valuable, will want to read more of the main volume and at least to sample the Appendix to see the kinds of information that can be mined from it. When patients are satisfied with a new treatment and seem to be improved by it, why bother with any additional evaluation? The reason is that history has shown over and over again that new forms of treatment initially can be used enthusiastically for many conditions with apparent success, only to have the pendulum swing in the opposite direction from overenthusiasm to com plete disillusionment.







Biofeedback and the Modification of Behavior


Book Description

In this book, I have attempted to evaluate critically the very large literature which has accumulated in the area of biofeedback over the past 10-15 years. As might be expected in any area of psychology with clinical possibilities, the literature divides itself into two main categories-fundamental research studies and therapeutic studies. It is now apparent that the clinical applications of biofeed back have far outstripped their fundamental research bases, with the inevitable result that the initial wave of enthusiasm may be replaced with an unnecessarily severe skepticism. Either extreme position is unjustified. Biofeedback does rep resent an important new approach to the elucidation of the role played by internal systems in the adjustment of the organism to its environment. But its potential will only be revealed if its use in practice is soundly based on fundamental research. There are promising signs that this is being realized so that there is cause for optimism. Aubrey J. Yates Perth, Australia A Note on the References With the exception of no more than two or three papers, all the references in this book have been obtained and read. However, many of them were published in journals which will not be readily accessible to the reader who may be interested in consulting more directly particular articles which attract his attention.




The Effects of EMG Biofeedback Training and Relaxation Training on Self-reported Measures of Trait Anxiety and Sports Competition Anxiety


Book Description

This study examined the singular and combined effects of a progressive relaxation and biofeedback monitoring program upon Trait Anxiety, Sports Competition Anxiety, blood pressure, heart rate, and muscle tension as measured by EMG readings. The programs were administered over a six-week sequence, with pre-measures utilizing the Spielberger Trait Anxiety measure, the Sports Competition Anxiety Test, and Rotter's Locus of Control Test to evaluate the psychological parameters. In addition, blood pressure and resting heart rate data were collected one hour prior to three competitive duo meets and prior to "warm-up". EMG monitoring by biofeedback was accomplished through use of the Autogen 1100 Myograph at a band pass setting of 100 to 200 Hz. EMG measures were made by use of the Autogen 5100 Digital Integrator using time-averaged performance of each subject. These measures were independent of the analysis feedback. All pre-measures were gathered prior to the various treatment strategies. The subjects were 36 male collegiate varsity track and field athletes divided into one of four treatment cells containing nine subjects each. Each group met for a total of twelve one-half hour sessions and participated in either a cassette-taped Quieting Response program, a Quieting Response program with augmented EMG biofeedback, or EMG biofeedback alone. The control group was administered the assessment items and blood pressure and resting heart rate measures to include EMG time-averaging monitoring. In lieu of treatment, the control group attended twelve one-half hour sessions of passive rest and listened to "music of choice" during these sessions. Statistical analysis using repeated-measures analysis of variance (ANOVA) revealed that EMG measures were significantly reduced through the six weeks of training using relaxation training alone, biofeedback training, and combined relaxation/biofeedback training. There were no differences as a result of treatment effect for the variables for between group significance for any of the variables to include Trait Anxiety, Sports Competition Anxiety, Locus of Control, blood pressure, and resting heart rate.
