I have been using Biofeedback training with my clients in my role as a behavioral psychologist for more than 30 years. Biofeedback equipment monitors or measures various physiological functions and allows the client and therapist the opportunity see and/ or hear what is being looked at. With advancements in electronics, now days you can go to Sports Authority and purchase a portable wrist watch heart rate monitor. It would tell you what your heart rate is in real time. If you wanted to use biofeedback to get a better work out, you could set the watch so that it would start beeping if you heart rate fell below the rate that you set it at. To get the beeps to stop, you would need to exercise harder to increase your heart rate.
If you wanted to become calmer and more relaxed, your goal would be to slow down your heart rate. You would set the watch so that if it exceeded a certain number of beats per minute, the “beeps” would go off.
As a psychologist, using biofeedback, I would first teach you a form of relaxation training, such as deep breathing, muscle relaxation or guided visualization and then monitor your ability to control your heart rate and/ or muscle tension. As you became more proficient, I would adjust the sensitivity of the biofeedback machine so that it would require you to relax increasingly deeper to keep the beeps off. This is essentially how biofeedback training works.
With the use of computers and various software programs, you can now have pictures and games to motivate you. For example, in a game, you are floating in a hot air balloon and the deeper you relax the higher the balloon on the screen goes.
Many individuals who like objective measures to monitor their progress like to use biofeedback training as a part of their treatment program whether it be to regulate emotions or improve concentration and attention.
