Transcript

  • 1. BIOFEEDBACK
  • 2. • When you raise your hand to wave hello to a friend, or lift your knee to take another step on the Stairmaster, you control these actions. • Other body functions – like heart rate, skin temperature, and blood pressure -- are controlled involuntarily by your nervous system. • You don't think about making your heart beat faster. It just happens in response to your environment, like when you're nervous, excited, or exercising. • One technique can help you gain more control over these normally involuntary functions. • It's called biofeedback, and the therapy is used to help prevent or treat conditions including migraine headaches, chronic pain, incontinence, and high blood pressure.
  • 3. BIOFEEDBACK • Biofeedback is the process of gaining greater awareness of many physiological functions primarily using instruments that provide information on the activity of those same systems, with a goal of being able to manipulate them at will • The idea behind biofeedback is that, by harnessing the power of your mind and becoming aware of what's going on inside your body, you can gain more control over your health.
  • 4. How Does Biofeedback Therapy Work? • Researchers aren't exactly sure how or why biofeedback works. They do know that biofeedback promotes relaxation, which can help relieve a number of conditions that are related to stress. • During a biofeedback session, electrodes are attached to your skin. These electrodes send signals to a monitor, which displays a sound, flash of light, or image that represents your heart and breathing rate, blood pressure, skin temperature, sweating, or muscle activity. • When you're under stress, these functions change. Your heart rate speeds up, your muscles tighten, your blood pressure rises, you start to sweat, and your breathing quickens. You can see these stress responses as they happen on the monitor, and then get immediate feedback as you try to stop them.
  • 5. Several different relaxation exercises used in biofeedback therapy • A biofeedback therapist helps you practice relaxation exercises, which you fine-tune to control different body functions. For example, you might use a relaxation technique to turn down the brainwaves that activate when you have a headache. • Several different relaxation exercises are used in biofeedback therapy, including: • Deep breathing • Progressive muscle relaxation -- alternately tightening and then relaxing different muscle groups • Guided imagery -- concentrating on a specific image (such as the color and texture of an orange) to focus your mind and make you feel more relaxed • Mindfulness meditation -- focusing your thoughts and letting go of negative emotions • As you slow your heart rate, lower your blood pressure, and ease muscle tension, you'll get instant feedback on the screen. Eventually you'll learn how control these functions on your own, without the biofeedback equipment.
  • 6. Different types of biofeedback are used to monitor different body functions:
  • 7. Electromyogram (EMG) • This measures muscle activity and tension. It may be used for back pain, headaches, anxiety disorders, muscle retraining after injury, and incontinence.
  • 8. Thermal • This measures skin temperature. It may be used for headache and Raynaud's disease.
  • 9. Neurofeedback or electroencephalography (EEG) • This measures brain waves. It may be used for attention deficit hyperactivity disorder (ADHD), epilepsy and other seizure disorders.
  • 10. Electrodermal activity (EDA). • This measures sweating and can be used for pain and anxiety.
  • 11. Heart rate variability (HRA) • This measures heart rate. It may be used for anxiety, asthma, chronic obstructive pulmonary disease (COPD), and irregular heartbeat.
  • 12. • Each biofeedback therapy section lasts about 30 minutes. Usually, you can start to see biofeedback benefits within 10 sessions or less. Some conditions, such as high blood pressure, can take 20 or more sessions to improve.
  • 13. Biofeedback Uses • • • • • Chronic pain. By helping you identify tight muscles and then learn to relax those muscles, biofeedback may help relieve the discomfort of conditions like low back pain, abdominal pain, temporomandibular joint disorders (TMJ), and fibromyalgia. For pain relief, biofeedback can benefit people of all ages, from children to older adults. Headaches. Headaches are one of the best-studied biofeedback uses. Muscle tension and stress can trigger migraines and other types of headaches, and can make headache symptoms worse. There is good evidence that biofeedback therapy can relax muscles and ease stress to reduce both the frequency and severity of headaches. Biofeedback seems to be especially beneficial for headaches when it's combined with medications. Anxiety. Anxiety relief is one of the most common uses of biofeedback. Biofeedback lets you become more aware of your body's responses when you're stressed and anxious. Then you can learn how to control those responses. Urinary Incontinence. Biofeedback therapy can help people who have trouble controlling the urge to use the bathroom. Biofeedback can help women find and strengthen the pelvic floor muscles that control bladder emptying. After several sessions of biofeedback, women with incontinence may be able to reduce their urgent need to urinate and the number of accidents they have. Biofeedback can also help children who wet the bed, as well as people with fecal incontinence (the inability to control bowel movements). Unlike drugs used to treat incontinence, biofeedback doesn't tend to cause side effects. High Blood Pressure. Evidence on the use of biofeedback for high blood pressure has been mixed. Although the technique does seem to lower blood pressure slightly, biofeedback isn't as effective as medication for blood pressure control.
  • 14. Other biofeedback uses include: • • • • • • • • • Attention deficit hyperactivity disorder (ADHD) Chronic obstructive pulmonary disease (COPD) High blood pressure Raynaud's disease Injury Asthma Constipation Epilepsy Rheumatoid arthritis
