What is biofeedback?
Biofeedback is a modern, scientifically founded process of training.
With the aid of a computer, physiological processes which are otherwise difficult or impossible to perceive, are registered and thus made manifest and visible. These processes include, for example, muscle tensing, pulse, respiration or temperature.
With neurofeedback, brain activity is measured and registered.
Within the biofeedback process, the trainer can provide the client with a detailed report based on these measurements. The client can use these clear data to learn to influence physiological processes.
When can Biofeedback be used?
Biofeedback is used in the treatment of the following conditions, as well as many others:
- Psychological conditions
- Clarification of the background factors related to psychological and physiological processes.
- Stress, stress related disorders, stress relief
- Unclear physical conditions
- Sleep disorders, sexual disorders
- Hyperactivity, attention disorders
- Muscular tension
- Anxiety disorders, depression
- Post traumatic stress disorder
- Prevention of chronic disorders
- Improvement of body perception
- Psychological disorders / psychological consequences of physical illnesses

Which physical parameters are measured?
Among the most commonly used physical readings are:
- Muscle tension
- Skin conductivity (e.g. as a general measure of relaxation, stress, emotions)
- Skin temperature
- Diameter of the temporal artery
- Rate and depth of respiration
- Finger pulse (as a measure of peripheral circulation)
- EEG-readings (for promotion of central-nervous ordered relaxation, attention, concentration and much more.)
- Heart rate
With neurofeedback the electric brain activity is measured by EEG.
Here is a very nice infographic from the blog www.psysci.co which illustrates the possibilities of Biofeedback.
