从假名（日语音节）和汉字（日中文字或符号）的角度探讨了无书写障碍的日语失读症的恢复机制。在主要强调运动觉促进的治疗过程中，我们的患者在大声朗读kanaan和kanjii方面表现出改善，并有模仿它们的动作。在后期阶段，在没有模仿动作的情况下大声朗读也有改善。我们还观察到，正确读取字符组成部分的数量增加了。对患者康复机制的后续研究显示：(1)患者的右手在模仿熟悉的汉字方面有所改善，而同只手在模仿未使用的汉字和追踪汉字方面仍然受损，而与频率无关；(2)患者的朗读能力明显受到与右上肢同时进行三角形重复动作的任务的阻碍，尽管用同一条肢体敲击没有阻碍。由此推断，参与汉字的动觉图像，而不是视觉图像的恢复，有助于改善我们的病人大声朗读。在他的右侧视觉皮层接收到的视觉刺激可能会通过连接纤维的完整部分在语言区唤起对字符的动觉图像。
Mechanisms of the recovery of a Japanese alexic without agraphia were discussed in terms ofkana(Japanese syllabaries) andkanji(Japanese-Chinese characters or logograms). In the course of the therapy where kinesthetic facilitation was predominantly emphasized, our patient showed improvement in readingkanaandkanjialoud with actions of copying them. At the later stage improvement was also observed in reading aloud without the copying actions. We also observed that the number of correctly read components of a character increased. Follow-up studies to investigate mechanisms of the patient's recovery revealed the following results: (1) his right hand improved in copying familiarkanjiwhile the same hand was still impaired in copying unusedkanjiand in tracingkanjiregardless of frequency, and (2) his ability to readkanaaloud was significantly hindered by the concurrent task of triangular repetitive movements with the right upper limb although it was not hindered by tapping with the same limb. It is inferred that participation of kinesthetic images of characters rather than restoration of visual images contributed to the improvement in reading aloud in our patient. Visual stimuli received in his right visual cortex presumably became able to evoke a kinesthetic image of characters in the language areas by way of intact parts of commissural fibres.
