This essay is a study aimed at the therapeutic value of Drama for the handicapped children. Dramatherapy is based upon the two origins of drama : ‘dran’-movement, fiction and mimesis, and ‘now and here’-the presence and the existence. Dramatherapy is more effective for the mental disease than for the physical illness, because the drama’s structure is the same as that of the life. Drama can bring the change to be a social existence. Drama is therefore the best of art-therapy for the mental handicapped children for whom we must educate the development of social flexibility. The ideas of mind’s dramatic structure and the dramatic progress EPR by Sue Jennings, being from the drama itself, can guide to analyse the cause of mental illness and to find the solution. The mind’s dramatic structure has four parts : guidance, technique, artist and hurt. Each of the handicapped children has their own lack. For example, the part of artist is more excessive than other parts for the autistic children. So the dramatic progress EPR is variable according to mind’s dramatic structure. We can prove that Dramatherapy has to be regularly done not individually but in group and that the theatre performance as final course reveals its results. The value of dramatherapy based upon the literary fiction is to promote the patient’s spontaneity, imagination and originality. Drama activity has a functional relation with the change of community. In the world changing fast and unconsciously dramatherapy may be not only one of some drama forms but also the most important ground of drama, because of its effects beyond expectation. That’s why we must develop many ways of dramatherapy instead of passive forms of drama education. 【key words】Dramatherapy, Art-therapy, Education for the handicapped children, Drama and fiction
