What is a Biofeedback Instrument?

Leave a comment

A biofeedback instrument is a device that uses sensors to measure a signal from the body related to your nervous system that then shows you the information as it is being measured.  It is different than getting your blood pressure checked or taking your pulse and getting one reading for one moment in time.  The measurement and feedback of information are continuous.

This information can be used for monitoring and might not even be shown to the person that it is being measured from.  This is sometimes done in research.  Let’s say a researcher wants to find out how a person’s body reacts to watching a scary movie or counting backward by 7’s. They could attach sensors to a subject and monitor signals like heart rate or sweat activity to acquire a measurement related to the physiological reaction of the stimulus.  When used in this way it would be more accurate to refer to the process as physiological monitoring instead of biofeedback.

Skin Conductance Biofeedback

Leave a comment

Skin Conductance can be both one of the simplest yet one of the most complex modalities of biofeedback at the same time.  More stress, the reading goes up.  More relaxed, the reading goes down.  Simple, right?  Not so fast.  Make sure we are not actually talking about resistance measures which are exactly opposite from conductance.  Besides two opposite measures of conductance and resistance, we should also add skin potential.  When I was introduced to biofeedback way back in 1984, GSR or Galvanic Skin Response was the common feedback modality for monitoring changes based on sweat activity.  The readings in Ohms would go down when there was more sweat on the skin because resistance was decreasing and it would go up if the amount of sweat decreased because resistance was increasing.  The audio tone was reversed so that it went up when the subject was responding to something and got lower when they recovered or calmed down.

BCIA Certification Biofeedback Seminars

How can you determine if the biofeedback provider you are considering visiting is qualified?

One good way is to get a personal referral.  If you know someone who has had success with a biofeedback provider for a similar problem as your own then there is a good chance that you may also get good results and be happy with them too.  There are other things that you can do to get an idea as to their qualifications.  One of the best ways to determine qualification is to find out if the provider is BCIA certified.  What is the BCIA?  BCIA stands for Biofeedback Certification International Alliance.

The BCIA is the organization that establishes the rules for and provides certification in biofeedback and neurofeedback.  Here is their mission: “BCIA certifies individuals who meet education and training standards in biofeedback and progressively recertifies those who advance their knowledge through continuing education.”
