Biofeedback is a non-invasive therapy that uses devices to monitor feedback signals from the body to help patients regulate biological functions. Different types of biofeedback devices are used depending on the condition present, such as EEG for brain wave activity, EDR for emotional arousal, and EMG for muscle tension. Biofeedback therapy is used to treat a variety of conditions, but it cannot prevent or cure diseases.
Biofeedback is a non-invasive therapy used to help patients regulate various biological functions by monitoring different feedback signals provided by the body. For example, when biofeedback devices emit a flashing light, buzzer, or other signal pattern to indicate an increase in blood pressure, the patient focuses on reducing the frequency or intensity of the signal to improve the condition that caused it. the peak. In fact, biofeedback treatment is very similar to a conditioning exercise for the patient in which the biofeedback device acts as a coach. Which types of biofeedback devices are used depends on the condition present. In fact, there are different types of biofeedback systems.
One of the most common biofeedback devices in use is the electroencephalogram (EEG), which measures brain wave activity in relation to mental alertness and muscle tension. While beta brain wave activity occurs during normal wakefulness, alpha brain wave activity suggests a relaxed state. On the other hand, theta brain waves are associated with being in early stage sleep, while delta waves are seen during deep sleep.
Therapists believe that by consciously altering the rate at which brain waves occur, various neurological conditions can be addressed. For example, a therapist might employ this device to help patients suffering from anxiety increase alpha brain wave activity or to help epileptics reduce the frequency of seizures through regulation of theta brain waves.
One of the most accurate biofeedback devices is the electrodermal response machine (EDR), which senses light electrical impulses in the skin generated by sweat glands. Specifically, this tool measures the fluctuating levels of water and salt excreted from the sweat gland ducts on the skin. This type of biofeedback therapy is used to help patients who exhibit high levels of emotional arousal, perhaps due to traumatic events or phobias. Athletes also use this device to help reduce anxiety before competing. Of course, this device is also known to law enforcement as it is used to administer lie detector tests.
An electromyogram (EMG) is another type of biofeedback device used to measure tension in various muscle groups. This technique has proven useful in treating patients with muscle impairment or even complete muscle loss. In fact, it is used to stimulate muscle activity and the growth of new nerves in patients who have had paralysis due to a stroke. Furthermore, this machine provides feedback in terms of muscle relaxation, making it useful in training patients to relieve stress-induced conditions, such as tension headaches or chronic neck and back pain.
Medical professionals, such as physical therapists, psychologists and psychiatrists, dentists, etc., typically provide biofeedback training to individuals. The list of conditions treated with biofeedback has grown considerably since its introduction in the early 1960s to include migraines, cardiac arrhythmias, high blood pressure, epilepsy, paralysis, and circulatory disorders, such as Raynaud’s disease. However, while biofeedback therapy can be very helpful for many people, it alone cannot prevent or cure the disease.
