What is Biofeedback?
Many alternative medicine methods involve an increased consciousness of one’s own body. This awareness of physiological functions is often accomplished through biofeedback – a process that uses measurements and various devices to show how various aspects, such as brainwaves, muscle tone, and heart rate react to changes in movement, breathing, or concentration. Those who take part in this practice enough eventually become skilled enough to do so without the assistance of external instrumentation.
There are many common instruments used in biofeedback. Use of electromyography determines one’s muscle action. The feedback thermometer measures the temperature of an extremity such as a toe or finger. An electroencephalograph is a common way of measuring brain activity through neurofeedback monitors. Another common device is a pneumograph, which can provide information about breathing rates as well as the depth of breathing.
There are many different practical applications of biofeedback. One simple example is a bedwetting alarm – a simple bell that rings to awake a child that has wet his or her bed. Over time, the child learns to control themselves and the bedwetting ceases. Some who have high blood pressure or a pulse that rises due to stress can learn to control this, bringing pressure and speed down to a healthier level. Interestingly enough, people have also learned to control pain sensitivity through use of biofeedback training. This is especially helpful for those who suffer from chronic pain disorders, or those undergoing painful treatment for another disease.
Biofeedback is a scientifically valid method of training that is helpful in improving one’s health and increasing comfort levels. It can help people overcome everything from health problems to mental problems, as well as social interaction disorders. Biofeedback techniques have changed some since the theory was first proposed in 1865, but the basic principles remain the same – and there are countless studies to back up its validity.
