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.
基于将声学波动转化为电信号的关节运动记录（波形记录）方法，被用于确定脑卒中后言语障碍的特征和程度。对20名正常人和18名脑卒中后有言语障碍的患者进行了动态研究。作者评估了潜伏期的持续时间以及音素、单词和短语的发音速度。在运动性言语缺陷中发现了以下障碍：发音方面，潜伏期延长、语速减慢；在感觉方面，声音感知不稳定、组合失败。因此，通过波形记录法客观化的失语症障碍揭示了不同语言层次（音素、单词、短语）的病理情况，不仅取决于声带肌肉的痉挛和失用症，还取决于皮质过程的进展时间。言语活动的恢复并非同时在所有层次上发生，而最易受影响的似乎是音素层次。
