What is Biofeedback?

For a visual demonstration of Biofeedback, visit this video on you tube:  


        Biofeedback operates on the notion that we have the innate ability and potential to influence the automatic functions of our bodies through the exertion of will and mind.  Using a special machine and sensors to record muscle contractions and skin temperature, you can learn to control normally involuntary processes e.g. heart rate and blood pressure that increase under stress.

        The machine "feeds back" the efforts and eventually you can recognize and control facets of the stress response by yourself.   The control of "involuntary" responses is now seen to be effective in the treatment of migraine headaches, asthma and other disorders in certain individuals.

Heart Rate Variability - HRV

        As stress increases, heart rate variability - the heart's ability to beat faster or slower in response to emotion or physical demands - decreases.  Heart rate variability (HRV) is a measurement of cardiovascular health. More HRV means your heart is better able to adapt - resilient; less HRV means nerves and heart muscle can't respond easily to change, potentially leading to out-of-rhythm beats or an abrupt, fatal stop.

        Stress may reduce HRV by affecting nerves that control the heart. What you can do: Soothe and protect your heart with stress reduction and exercise.

Electrodermal/Galvanic Skin Response (EDR/GSR)

        Electrical conductance in the skin is associated with the activity of the sweat glands. A slight electrical current is run through your skin. The machine measures changes in the salt and water in your sweat gland ducts. The more emotionally aroused you are, the more active your sweat glands are and the greater the electrical conductivity of your skin.

        GSR is effective in treating phobias, anxiety, excessive sweating, and, at times, stuttering since these emotions will affect your skin's conductivity. It is used as a lie detection test. Athletes use this technique to prepare for games - to make sure that they are not too anxious or have pre-game jitters.

Electroencephalogram (EEG)  Biofeedback (also known as neurofeedback)

        This device monitors brain wave activity. The brain emits many electrical signals of various frequencies. Some of these waves relate to specific disorders or mental states. The following are some of the common classifications of brain waves:  Beta (awake); Alpha (calm relaxation); Theta (light sleep); Delta (deep sleep).  Examples of neurofeedback in therapy are:  Alpha waves being encouraged for relaxation, and relief from anxiety, insomnia and perhaps epilepsy. Insomniacs and those with attention deficits may also be taught to control theta waves.
