Autogenic Training - Qualitative Meta-Analysis of Controlled Clinical Studies and Relation to NaturopathyAutogenic training is a relaxation technique based on autosuggestions and practice in the perception of 'natural' relaxating processes of the body with an increasing calm basic attitude. The psycho-physiological changes that occur after periodical exercises can be explained by a plausible model which has been empirically proved in many of its aspects. With regard to methodological aspects the present study deals with the qualitative meta-analysis of 64 controlled clinical studies from 1952 to 1997. The clinical effect of autogenic training on the main symptoms as exclusive or at least central psychotherapeutic intervention (partly in combination with a somatic basic therapy) was evaluated. It was proved that autogenic training has positive effects on psychosomatic disorders (hypertension, asthma, intestinal diseases, 'vegetative dystonia', glaucoma, atopic eczema), on preparation for childbirth, sleep disorders and anxiety disorders. A positive effect can also be expected in case of headaches and Raynaud's disease, however, other relaxation techniques seem to be superior in these cases. Moreover, positive effects on the mood (e. g. depressive symptoms) and the general subjective condition (e. g. 'quality of life') have been proved by many studies. Hence indications can be derived according to the basic rules of evidence-based medicine. Nevertheless there are contraindications, for instance regarding exogenous, acute schizophrenic or affective psychosis. Beyond that the preparedness to therapy of many patients can be improved if the therapeutic offers are enlarged by autogenic training as a 'low level' offer. Autogenic training is an effective and useful component of preventive, rehabilitative or therapeutic interventions and can last but not least be part of therapeutic interventions which include naturopathy.
