To investigate the functional plasticity of the brain in childhood, the speech development, the intelligence test and dichotic listening test were performed on 27 patients who had suffered from hemiplegia under 1 year of age. Among 13 patients with right hemiplegia, 7 to 24 years old, 11 patients showed a left ear dominance suggesting the lateralization of language in the right hemisphere. All 14 patients with left hemiplegia, 5 to 37 years old, showed a right ear dominance suggesting the lateralization of language in the left hemisphere. All 27 patients acquired speech function enough to converse with other people during daily life. There were no differences in speech development or intelligence scores between both groups of hemiplegia. Although there was no correlation between the speech development and the age of onset of hemiplegia, there was a correlation between the speech development and the intelligence score in both groups of hemiplegia.
为研究儿童大脑的功能可塑性，对27例1岁前患偏瘫的患者进行了言语发育、智力测试和双耳分听测试。在13例7至24岁的右偏瘫患者中，11例表现为左耳优势，提示语言在右半球的侧化。14例5至37岁的左偏瘫患者均表现为右耳优势，提示语言在左半球的侧化。所有27例患者均获得了足够的言语功能，能够在日常生活中与他人交谈。两组偏瘫患者在言语发育或智力得分上无差异。虽然言语发育与偏瘫发病年龄之间无相关性，但两组偏瘫患者的言语发育与智力得分之间存在相关性。
