 We report the facilitation effects of kinesthetic reading in aphasic alexia, not pure alexia. The subject was a 47-year-old male who demonstrated severe fluent aphasia following an extended occlusion in the middle cerebral artery. Severe disabilities in reading kana characters had not recovered during the three years since the onset of aphasia, although he sometimes succeeded in reading kana characters after tracing them. We studied the facilitation effects of kinesthetic reading in 25 kana characters which stand for voiced consonant-vowel syllables, using a method of single case study. As a result, significant facilitation effects of kinesthetic reading were obtained. Pure alexia is thought to be caused by disturbances in the visual cognition of letters and/or disconnection between the visual information and the letter representation in the brain. The underlying mechanisms of kinesthetic reading are thought to be that the writing movement could activate the visual representation of letters. The fact that facilitation effects of kinesthetic reading were obtained not only in pure alexia, but in aphasic alexia too, could suggest the existence of a direct route from the kinesthetic representation of writing kana characters to their phonological representation.
