Pankow has developed a psychoanalytic psychotherapy of the psychoses which emphasizes the body image. Psychosis consists of the destruction of the fundamental symbolic structures which contain the first experiences of the body. In neurosis, these symbolic structures are deformed rather than destroyed. Pankow uses "dynamic structuralization" to intervene with psychotic patients in this process of destruction. In her technique she focuses on a potential space which was important in the development of a sense of separateness from the mother. Theoretical justifications for her technical innovations are presented. She feels that her work deals with phenomena similar to Winnicott's transitional objects. This potential space is often left out of consideration in classical psychoanalysis. There are many paradoxes and difficulties in the theoretical characterization of such intermediate phenomena. The question has been raised whether a new structural theory might be needed to accommodate these phenomena.
