The clinical vignettes show the risk for the analyst resonating with the severely ill patient to contract a similar illness. In one case, from within the patient-psychoanalyst relationship and in a moment of crisis, a series of communicative exchanges through bodies come to the fore: the anguished body of the patient and the aching body of the analyst. In the crisis of the relationship a health risk becomes apparent for both, patient and analyst. At the same time, both experience a new primary object in the transference: the jammed therapeutic process resumes with renewed impetus. Some theoretical considerations on non-verbal exchanges in the psychoanalytic relationship follow.

KEY WORDS: Body language, psychoanalytic process, transference, transformations, unison.
