Biofeedback is a holistic type of treatment researched and developed over 
30 years ago that uses instruments to measure one's level of stress in treatment 
modalities such as muscle Feedback (EMG); Temperature (Hand), Cognitive Feedback 
(EDR), and Blood Pressure. Other treatment modalities are used for some other areas of 
treatments not mentioned here. 
The goal of treatment is to teach the client to reduce his/her level of stress, and learn how to 
cope to alleviate the harmful causes of stress without the use of the instruments.

Biofeedback is a treatment technique in which people are trained to improve their health
by using signals from their own bodies. Physical therapists use biofeedback to help stroke
victims regain movement in paralyzed muscles. Psychologists use it to help tense and
anxious clients learn to relax. Specialists in many different fields use biofeedback to help
their patients cope with pain.
Clinicians reply on complicated biofeedback machines in somewhat the same way that you
rely on your scale or thermometer. Their machines can detect a person's internal bodily
functions with far greater sensitivity and precision than a person can alone. This
information may be valuable. Both patients and therapists use it to gauge and direct the
progress of treatment.
