Abstract

A biofeedback therapy system in which an individual during a training run in stress control is intermittently subjected to stress-inducing stimuli while one of his physiologic functions is being continuously monitored. The individual is able to observe the effect of the stimuli on a stress-graduated tripartite scale, making it possible for the individual to regulate the function being monitored. The scale takes the form of three series of light indicators, the first being graduated in gross steps, the second in increments of a gross step, and the third in fractions of one increment, whereby the readout accurately reflects the prevailing stress level. The tripartite scale is provided with adjustable markers which can be set on the scale to present the stress level at the time a training run is commenced so that subsequent changes in stress level are seen as deviations from the set point.

Claims

1. A biofeedback therapy system for training an individual to regulate his internal stress, which individual at the outset of a training run may be in a relatively unstressed state, said system comprising:

A means including a sensor continuously to monitor a physiologic function of the individual in the course of the training run to produce a signal representing the individual'"'"'s prevailing level of stress;

B a scale responsive to said signal to visually indicate the level of stress, making it possible for the individual mentally to regulate the function being monitored; and

C means to subject the individual being monitored during the course of the training run to a series of startling and disquieting stress-inducing sound stimuli which differ from each other and which appear at random intervals, and are therefore unexpected, to induce internal stress in the individual in the course of the run, said means being constituted by a tape recording having startling sounds recorded thereon at intermittent times which are disturbing to the listener.

2. A system as set forth in claim 1, wherein said sensor measures temperature.

3. A system as set forth in claim 2, wherein said temperature sensor produces an analog voltage which is converted into a digital pulse count that is represented on said scale.

4. A system a set forth in claim 1, wherein said startling sounds are superimposed over a base recording which is relaxation-inducing.

5. A system as set forth in claim 1, wherein said scale is a tripartite scale having a first, a second and third series of sequentially activated light indicators, the first series providing a gross step reading of stress whose general level depends on which indicator in the series is activated;

the second series providing a reading in which the step is divided into increments; and

the third series providing a reading in which the increment is divided into sub-increments.

6. A system as set forth in claim 5, wherein the three series are displayed in parallel rows on a panel.

7. A system as set forth in claim 6, further including a slidable marker under each row which is settable to a position indicating the stress of the individual at the commencement of the training run, the markers providing a stress set point.
