Due to the use of biofeedback devices, various biological processes which cannot be ascertained through direct sensory perceptions, can be recorded and influenced. In applying biofeedback devices, it is possible to gradually influence muscle tones in the different parts of the body as well as the activity of the autonomic nervous system and breathing patterns. In certain diseases, these changes are often necessary in order to relieve symptoms and so to trigger the healing process.
The application of biofeedback is wide-ranging and among others, includes the following areas:
- pain syndromes (backache, headache and others etc.)
- cardiovascular diseases
- stress management
- sleep disorders
Another type of biofeedback device is known as neurofeedback, which records brainwave activities using EEG. Neurofeedback is applied in a medical capacity e. g. for attention deficit hyperactivity disorder (ADHD), pain management or epilepsy.
