At present no methods for the prediction of the possibility of using electrostimulation are applied, in spite of the fact that the latter technique is employed on a large scale for patients rehabilitation. The authors have designed a method for electropulse diagnosis of changes in the anus, permitting the detection of pathological alterations in the anus as well as the identification of its reserve potentialities along with the solution of the problem as to whether direct electrostimulation can be used for rehabilitation of one or another patient. The given paper is concerned with a study into electropulse diagnosis of changes in the anus in 31 patients without derangement of locking function, with immaterial functional disorders, and with gross organic pathology. The direct dynamic electrostimulation of the anus appeared little effective in gross organic pathology of the anus, producing a beneficial effect in patients with functional disorders.
