脑损害病人运用障碍的成套测验研究

A Study of Dyspraxia in Brain 一damaged Patients by Using a Battery of Praxis Tests.

参照国内外学者使用过的检查项目编制了一套运用功能测验，对３０名对照及５２例脑损害病人施测后发现，左右侧额叶、顶叶、丘脑、基底节及左枕叶、左内囊、左外囊、右外囊和胼胝体等部位受损都可引起失用症，观念运动性失用症和结构性失用症发生率较高且左右半球受损无显著差异；观念性失用症发生率较低并都是左半球受损。结果提示失用症是脑损害病人的常见症状但却没有局部定位意义。

brain damaged Patients and 30 control Patients were adninistrated with a set ofneuropsychological test developed by us to investigate ideomotor apraxia(IMA) ,ideational apraixa(IA)and constructional apraxia (CA) ,The result showed that lesions of left or right frontal lobe and parietral lobe ,thalamus ,basal nuclei and left occipital lobe ,internal capsule, right external apsuleand other regions can separately cause apraxia, Brain一damaged patients had a high incidence of IMAand CA, and the contribution of left or right hemispher shows no difference, There were only twopatients with IA ,and both of them were suffered from the damage of left cerebral. These resultssuggest that though apraxia is a common syndrome in patients with brain damage ,it has little value inlocating the loci of cerebral lesions.
