Concerning the technical devices the applications of Biofeedback treatment can be divided in two major fields:

Portable Biofeedback devices, EMG-devices, EDA-devices and those that can be handed out to the patient after induction are counted among these. The latter can be used for relaxation training (e.g.) during stressful situations or in the evening before sleeping. Also incontinency trainers belong to this field of application. They facilitate the specific training of the muscles of the pelvic floor beyond the therapeutic setting.

Steady multichannel data acquisition in the medical or therapeutic practice Computer programmes allow a simultaneous measurement of body signals and presentation of these on a computer screen. This is essentially for demonstrating the interaction of different physiological processes and for identifying typical or possibly suspicious reaction patterns of the body. The quality improvement of these multichannel devices has increased to the extent that they can also be used for scientifically psycho-physiological studies. The body signals most commonly recorded are:

 

  • Muscle tensions (e.g. tension headache)
  • Skin conductance as a general measure for relaxation
  • Skin temperature (e.g. for the treatment of Morbus Raynaud)
  • Diameter of the temporal artery (for the treatment of migraine)
  • Breathing frequency and breathing deepness (e.g. hyperventilation syndrome, bronchial asthma, panic disorders, pain)
  • Blood pressure (for the treatment of essential hypertension)
  • Finger pulse (measure for peripheral blood flow)
  • EEG recording (stimulation of central nervous driven relaxation, partly for the treatment of epilepsy)
  • Muscles of the pelvic floor (incontinency training)
  • Heart rate (e.g. for tachycardia, panic disorders)
  • Anal sphincter (e.g. for obstipations, inflammatory bowel diseases, faecal incontinency)
