[An oscilllographic study of the speech of patients with cerebral circulatory disorders during the period of recovery from aphasia].
The articulation-phonographic (oscillographic) method of registration based on the transformation of acoustic fluctuations into an electrical signal was used for the determination of a character and degree of speech disturbances following brain strokes. Twenty normals and 18 patients with speech disturbances following brain strokes were studied in dynamics. The authors evaluated the duration of the latent period and the pronounciation rate of phonemes, words phrases. The following disturbances were marked in the motor speech defects: articulational, lengthening of the latent period, retardation of the speech rate; in the sensorial - lability of sound perception, failure of combinations. Thus, the aphatic disturbances, objectivized by the oscillographic method, reveal the pathology of various language levels (phonemes, words, phrases) and depend not only on the spasticity and apraxy of the vocal muscles, but on the time of the course of the cortical processes. The rehabilitation of the speech activity takes place simultaneously not on all the levels, while the most vulnerable appears to be the phonemic level.
