Biofeedback
Therapy and the L.I.F.E. System
The word 'biofeedback' was coined in the late 1969 to describe
laboratory procedures (developed in the 1940's) that trained
research subjects to alter brain activity, blood pressure,
muscle tension, heart rate and other bodily functions that
are not normally controlled voluntarily. Biofeedback is a
training technique in which people are taught to improve their
health and performance by using signals from their own bodies.
One commonly used device, for example, picks up electrical
signals from the muscles and translates the signals into a
form that people can detect. This device triggers a flashing
light or activates a beeper every time muscles become more
tense. If one wants to relax tense muscles, one must try to
slow down the flashing or beeping. People learn to associate
sensations from the muscle with actual levels of tension and
develop a new, healthy habit of keeping muscles only as tense
as is necessary for as long as necessary. After treatment,
individuals are then able to repeat this response at will
without being attached to the sensors.
Other biological functions which are commonly measured and
used in similar way to help people learn to control their
physical functioning are skin temperature, heart rate, sweat
gland activity, and brainwave activity.
Clinicians rely 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 clients and therapists
use it to gauge and direct the progress of treatment.
Although most people initially viewed these practices with
skepticism, researchers proved that many individuals could
alter their involuntary responses by being 'fed back' information
either visually or audibly about what was occurring in their
bodies.
In addition, studies have shown that we have more control
over so-called involuntary bodily functions than we once thought
possible. As a result, biofeedback can train individuals with
techniques for living a healthier life overall - whether one
is afflicted with a medical condition or not.
