The authors studied the effectively of rehabilitation in 220 patients with a protracted course of the schizophrenic process in individually created conditions, at a usual industrial plant and in conditions of state farms. The clinical observations and dispersed analysis detected that there are multifold correlations between different clinical factors and the effectiveness of rehabilitation. The authors have their opinion concerning the necessity of elaborating differentiated clinical indications to the rehabilitation of schizophrenic patients with a prologned continuous stay in a hospital. According to 2-year following up the general outcome of rehabilitation was evaluated as favourable in 69%. These data permit to expand the present concept of the clinical and social prognosis in protracted forms of schizophrenia.
