INTRODUCTION
Deficient postural control is one of the key problems in cerebral palsy (CP). Little, however, is known about the specific nature of postural problems of children with CP, nor of the relation between abnormal posture and dysfunction of the visual system.
AIM OF THE STUDY
To provide additional information on the association of abnormalities in postural control and visual dysfunction of the anterior or posterior part of the visual system.
METHODS
Data resulting from ophthalmologic, orthoptic, neurological, neuro-radiological, and ethological investigations of more than 313 neurologically impaired children were retrospectively analyzed.
RESULTS
Abnormal postural control related to ocular and ocular motor disorders consisted of anomalous head control and subsequent abnormal head posture and torticollis. The abnormal postural control related to retrochiasmatical damage of the visual system consisted of a torticollis combined with adjustment of the upper part of the body, as if at the same time adapting to a combination of defects and optimizing residual visual functions.
CONCLUSION
Visual dysfunctions play a distinct role in the postural control of children with CP.
引言
姿势控制不足是脑瘫（CP）的关键问题之一。然而，对于脑瘫患儿姿势问题的具体性质，以及异常姿势与视觉系统功能障碍之间的关系，我们知之甚少。
研究目的
提供有关姿势控制异常与视觉系统前部或后部视觉功能障碍之间关联的更多信息。
方法
对313名以上神经功能受损儿童的眼科、视光学、神经学、神经放射学和行为学检查数据进行回顾性分析。
结果
与眼及眼球运动障碍相关的异常姿势控制包括异常头部控制以及随后的异常头位和斜颈。与视觉系统视交叉后损伤相关的异常姿势控制包括斜颈并伴有身体上部的调整，就好像同时在适应多种缺陷并优化残余视觉功能。
结论
视觉功能障碍在脑瘫患儿的姿势控制中起着独特作用。
