["One need not be a fakir or guru." Biofeedback as an interdisciplinary research technic]

With the technique of biofeedback it has become possible for humans to enter into a direct and objective dialogue with their body functions. By this method one can, for example, try to reduce muscle tension, increase peripheral blood flow or influence cortical activity. It has been clinically applied in neuromuscular rehabilitation, as an adjunct therapy of cardiovascular disorders such as cardiac arrhythmias and hypertension, in the treatment of headache and epileptic seizures as well as for bodily relaxation.
