[Voice and vibration sensations in the speech forming organs: clinical and theoretical aspects of rare symptoms specific for schizophrenia].
When studying 750 psychiatric in-patients with psychoses of various diagnostic groups, the symptoms of voice sensations and vibration feelings could only be found among patients with paranoid schizophrenia. In addition, these symptoms were located exclusively in body areas that are involved in the peripheral motor production of voice and speech (areas of head, throat, thorax). In 11 of 15 such cases that could be identified, the sensations of voices and vibrations occurred simultaneously and in identical body parts; in the remaining 4 cases only voices without vibration sensations were reported. Therefore these symptoms can be considered as highly specific for schizophrenia. According to the terminology of Bleuler these two symptoms are because of their rareness to be taken as accessoric symptoms; according to the terminology of Kurt Schneider they have the value of first rank symptoms because of their highly diagnostic specifity for schizophrenia. The pathogenesis of these symptoms is on the one hand discussed under the perspective of language development and the changing function of language for behaviour control; on the other hand, the pathogenesis of these symptoms is discussed from the viewpoint of cybernetic, or neurophysiological-neuroanatomical foundation of speech production and speech control. Both models of explanation have in common that the ideational component of speech is noticed as acustic halluzinations and the motor proprioceptive part of speech is noticed as sensation of vibrations, both in a typically schiphrenic manner, i.e. dissociated and ego-alienated.
