Biofeedback Equipment, 5 Things You Need to Know

Are you thinking of getting biofeedback equipment?  Here are 5 things you need to know.

  1. What is it measuring? Biofeedback instruments may measure different things.  All biofeedback instruments are not the same.  There are different modalities that can be measured including surface EMG for muscle tension, Skin Temperature, Skin Conductance, Respiration, Heart Rate, Heart Rate Variability, EEG, and CO2 (Capnometry).  Some biofeedback equipment measures only one of these modalities.  Others may measure up to 10 separate channels at the same time.
  1. Do I have a reliable signal? The feedback that the instrument provides is only as good as the quality of the signal.  If the signal is not accurate it is not a good representation of the changes happening in the body.  Some biofeedback equipment makes it easy to see the quality of the signal.  Other instruments may hide the actual signal and only show you a game or give you sound that is supposed to be reacting to the signal.

The Role of Biofeedback Equipment in Stress Management

Stress management is a huge subject.  There are many methods of managing stress.

One thing that is constant is that the body reacts to stress in several ways, many of which can be measured using biofeedback equipment.  People who are experiencing stress often have sensations that they can feel, if they are sensitive and present enough without biofeedback equipment.  These sensations may be related to changes in cardiovascular activity like your heart beating faster or more forcefully, blood vessels constricting, muscles contracting, increased sweat, changes in brain activity, or changes in digestive activity.  These changes are related to what is called physiology.  Whether a person feels these changes or not, they are happening.  What biofeedback equipment can do is make the invisible, visible.

Skin Conductance Biofeedback

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.”

How Biofeedback Training Reduces Stress

The Problem of Stress

Biofeedback training is an effective method for reducing the negative effects of stress.  There are many sources of stress including politics, natural disasters, terrorist acts, work, family, and financial problems, and traffic.  In this world of 24 hour TV and radio news plus news on our computers, we are constantly bombarded with stressful, negative information.  If that wasn’t enough we have smart phones, tablets, and smart watches with us at all times to make sure that we don’t miss anything.  Wherever we are we can stay up on what is happening.  Besides the information we get from news sources, we also get blogs and podcasts.  In addition to these stress sources, the people who we interact with who cause us stress are able to call, text, or email us 24 hours a day 7 days a week, 365 days a year.
