Biofeedback and behavioral medicine: an overview.

Biofeedback is a behavioral method of achieving or enhancing voluntary control of physiological processes. Basic studies indicate that a variety of autonomic nervous system and other internal bodily changes can be modified with the method. It has been shown that specific responses and patterns of responses can be controlled. Biofeedback appears to be a promising method of altering symptoms of psychophysiological and medical disorders, e.g., high blood pressure, vascular changes in migraine, neuromuscular abnormalities, and cardiac arrhythmias. This research has stimulated a renewed interest in the role of behavior and the usefulness of behavioral principles in the etiology, treatment, and prevention of medical disorders. The term 'behavioral medicine' calls attention to this new perspective in medicine.

Labor supply behavior of prospective and new mothers.

Utilizing unique data generated from the National Longitudinal Surveys of Young Women, this paper examines the labor force participation of young mothers in the months immediately preceding and following the birth of the first child. Labor supply behavior at this point in the life cycle is described in greater detail than has hitherto been available. In addition, we analyze the independent effect of several factors of interest on the probability that a young woman will be in the labor force during various intervals surrounding the first birth.

Total synthesis of ceramide trihexoside accumulating with Fabry's disease.

We report the synthesis of natural ceramide trihexoside, viz. gal (alpha-1 leads to 4) gal (beta-1 leads to 4) gluc (beta-1 leads to 1) ceramide (XIII). It involves the Koenigs-Knorr reaction of the bromide II with the aglucon XIX, and of the chloride VII with the D-enantiomer of the ceramide ester XII. A positional isomer of XIII was obtained as a by-product. A novel technique in the Koenings-Knorr reaction is described.

Effects of biofeedback and voluntary control procedures on heart rate and perception of pain during the cold pressor test.

The effects of biofeedback training and voluntary control procedures on heart rate and subjective reactions to 30-sec immersion of the hand in ice water were investigated in five experimental conditions, nine subjects in each condition. All subjects were given an initial cold pressor test and a final test interspersed by the particular condition. In two of the conditions, subjects were given biofeedback training for increasing or for decreasing heart rate. No training was given to the other three groups. In two of the latter conditions, subjects were simply asked to increase or decrease their heart rate during the second cold pressor test, without previous training. The fifth condition was a no-treatment habituation control. Significant variations between groups were obtained of the tachycardia and reports of pain associated with the second cold pressor test. In general, there was a correspondence between heart rate change and subjective report of pain. Voluntary control of heart rate or other autonomically-mediated responses, enhanced by biofeedback training, may have implications for research on and clinical management of physiological and subjective reactions to stressful stimuli.
