The use of biofeedback

What is biofeedback?

Biofeedback works much like neurofeedback, indeed Neurofeedback is a form of biofeedback. Biofeedback allows us to control the body's physiological functions that It seems out of control, Such as heart rate, body temperature, breathing rhythm and sweat. you may notice when you're anxious , skin perspiration increases.

For example, it is possible your palm sweats hardly . this is seen especially among children and adolescents when they have exam.  excessive sweating is a sign of anxiety, in most cases  we are not aware of it and most importantly, it seems we have no control over it . a form of biofeedback (biofeedback sweating or skin or Skin Conductance or SC) by connecting the sensors on hand , measures the electrical conductivity of the skin. Whenever the skin sweats , increase electrical conductivity and then reduce skin resistance, measuring the resistance , allows to know the sweat increasing  and make child aware of this  , at this time the child tries with the help of a therapist (Play Therapy) reduce his anxiety. the child gradually learns to control the sweat and  anxiety.

The most important types of biofeedback:

Electromyography : This method is used in a number of electrodes to measure muscle action potential.  the potential causes of muscle tension action.  athletes the stress by EMG, learns  its perceptions just mental and thus teaches controls it with observation .the EMG is used as a technique relaxation.

Thermometer Feedback : A thermistor attached to the finger or the tissue and measures the temperature of her body. Because the relationship that exists between chills and feeling stress, low body temperature indications are that the relaxation began.

Galvanic skin Response : There is a very weak electric current in the skin where people can not understand. The person is more emotionally aroused, sweat glands will be more. There was sweat on the skin reduces the skin's electrical resistance and will increase the electric current. athletes benefit from this device to reduce restlessness and anxiety before the tournament.

Respiratory biofeedback : The device provides measurement and feedback the rate and volume of inhale and exhale in areas such as thoracic breathing and abdominal breathing. this way, person aware of your breathing and sets it. usually when anxiety , breathing rhythm and volume is changed and vice versa to control the rhythm , anxiety and stress can be controlled.

History biofeedback Neel miller, Psychologists and neuroscientists that worked in the mid-twentieth century, Yale University, known as the father of modern biofeedback. He   , discovered the basic principles of biofeedback, conducting experiments on rats about classical conditioning. He and his team found that by stimulating the pleasure center in the brain of a paralyzed mouse by electricity, it is possible that they can be used it to control different effects including heart rate, blood pressure, body temperature and taught. Until then, experts believed that physiological processes (such as heart rate) are the exclusive control of the autonomous nervous system. Dr. Elmer Green did some research on the roots of human 's self-regulation in processes that are normally controlled by the unconscious mind. this technique can be used successfully to treat migraine headaches and high blood pressure .
