All of the biofeedback devices listed below allow patients to associate particular physiological effects of their body with how they feel emotionally and spiritually. In the process of determining this relationship for themselves, they can use their mind to change these physiological events from negative to positive. Reliance on these devices gradually decreases as the individuals learn to monitor their physiological effects internally.
- Electromyography (EMG): This test measures the health of muscles and the nerves managing them. By using this test, individuals can recognize symptoms before and during muscle tension, injury, and pain. Click here for more information on EMG.
- Thermal Biofeedback: This test measures skin temperature and can indicate problems with blood flow. Body temperature often drops during stress because arteries constrict causing blood flow to be limited to necessary organs and extremities. This reduced blood flow can lead to other problems like migraines and Raynaud’s disease (an ailment in which blood circulation can not reach fingers or toes). Using thermal biofeedback can help individuals recognize these symptoms and train their body to vasodilate.
- Electrodermal Activity: Also known as galvanic skin response, and even more commonly known as the lie detector, this test measures electrical conductivity of the skin. This process can help individuals work with issues related to anxiety.
- Finger Pulse Measurements: This test measures blood pressure and heart rate. Using this test helps patients work with their anxiety, high blood pressure, and cardiac problems.
- Respiration Feedback: This test measures breathing rate and allows patients to learn to control conditions such as anxiety, asthma, and hyperventilation.
- Electroencephalogram (EEG): Also known as neurofeedback, this test involves sensors attached to the patient’s scalp and ears and allows patients to learn to modify their brainwave activity. This test is commonly used for anxiety, stress disorders, and ADD/ADHD.
