[Biofeedback. I. Current status of its clinical application].

The aim of this article is to restate the question of the clinical application of biofeedback and its prospects after having defined it. After the huge success that biofeedback has known, some decantation is occurring. One is stricken by the absence of methodological closeness of too many studies, in this field, which very much limits the conclusions one can make presently. The best and most reliable results have been obtained by the biofeedback training of electromyogramme (elimination of subvocalization in reading, direct paralyzed muscles training, tension headaches treatment). The results are encouraging, but not yet enough backed up, as to regards to the improvement of various forms of epilepsy by the biofeedback training of the EEG sensorimotor rhythm, the premature ventricular contractions, sinus tachycardia and migraine headaches. In the other fields, the research status does not yet allow any valid conclusion.
