Reports on a significant institutional and therapeutic innovation at the Ibn Rochd and Pinel section of the Razi University long-term mental hospital in Tunis, TunisiThe innovation was introduced by E. Jeddi and his colleagues and focuses on the ambiguity of doors and boundaries in the mental asylum. Doors and walls influence the rhythm of activity and the nature of contact among patients, therapists, and the wider society and culture. If they are very rigid, they may disjoin the patient from him/herself, his/her body, social network, and culture. If such boundaries are completely neglected, they may merge these related dimensions as undifferentiated entities. Jeddi's innovation is primarily concerned with placing the spatio-temporal experience of the body and the intimate interpersonal interaction at the center of treatment. The present authors provide an anthropological perspective on the dance and music therapy at the hospital.
