项目摘要

Unilateral spatial neglect (USN) occurs most frequently by the lesions of right hemisphere. We examined eye movements in patients with right brain damage using the ultra-red rays reflection from the cornea and crystalline lens (Free View【○!R】, Takei Machine Industrial Corporation, Tokyo). Different number of targets distributed on the display were shown by the computerized system. The subjects were 14 patients (mean age : 63.2±9.7 years, 12 men and 2 women). All had different degrees of light hemiplegia. The patients were received occupational approaches for 6 weeks forward on the attention to the left visual field such as peg-board trasfer, symbol cancellation and block design. Test 1,2,3,4 : To count the number of targets distributed on the display in front of the patients. Test 5 : To read the Kana words distributed on the display.As a result, we classified the USN patients into three groups. (1) No USN group : They could follow exactly the targets which were displayed very fast. (2) Light USN group : They could gaze the targets shown slowly but could not follow the targets which shown very fast. (3) Severe USN group : They did not gaze the targets in the left side, but the attention to the right targets was seemed rather accelerated than the other groups. It was therefore considered that the attention of the USN patients shifted toward the right side. After 6 weeks occupational therapy, the gaze to the left targets was improved even in severe USN group as well as light USN group. Line bisection, symbol cancellation and BIT (Behavioural inattention test) were also significantly improved in severe USN group compared to light USN group. And their activity of daily living was also improved.Searching of the targets presented on the display by the computerized system would be an useful tool to train the USN not only to examine USN.

单侧空间忽视（USN）最常见于右半球病变。我们使用角膜和结晶透镜的超红色射线反射（免费视图[○！r]，Takei Machine Industrial Corporation，Tokyo）检查了具有右脑损伤的患者的眼球运动。计算机系统显示了显示在显示屏上的不同数量的目标。受试者是14例患者（平均年龄：63.2±9.7岁，男性和2名女性）。所有这些都有不同程度的轻度偏瘫。在关注左视野的关注时，将患者接受了6周的占领方法，例如PEG板转移，符号取消和阻滞设计。测试1,2,3,4：计算出患者面前分布的目标数量。测试5：读取在显示屏上分布的卡纳单词。结果，我们将USN患者分为三组。（1）没有USN组：他们可以准确地遵循非常快速显示的目标。（2）轻度USN组：他们可以凝视显示的目标缓慢，但无法遵循显示非常快的目标。（3）严重的USN组：他们没有凝视左侧的目标，但是对右目标的关注似乎比其他组相比要加速了。因此，认为USN患者的注意力转向右侧。 6周忙碌的治疗后，即使在严重的USN组以及轻型USN组中，对左目标的目光也得到了改善。与Light USN组相比，严重USN组的线一分配，符号取消和位（行为不注意测试）也显着改善。他们的日常生活活动也得到了改善。对计算机系统显示屏上显示的目标进行搜索将是训练USN的有用工具，不仅是检查USN。
