The presence of visual dependence as an influential factor on the development of functional stability in ambulatory individuals with cerebral palsy (CP) was studied in 22 adults with spastic bilateral CP, 11 of whom were considered visually dependent, and 18 healthy adults. Participants stood upright during pitch plane disturbances of the visual field and support surface. Intersegmental coordination behaviors were assessed by fitting trajectories of adjacent body segments to an ellipse. Mixed-model repeated measures ANOVAs were performed on ellipse orientation angle and area. Dissimilar stabilizing strategies adopted by the two groups with CP imply that visual dependence impacts postural control. Postural reorganization in response to visual flow in all groups indicates that we cannot ignore perceptual aspects of postural control when designing therapeutic interventions.

视觉依赖性对脑瘫直立姿势期间节间协调的影响。

在22名患有痉挛性双侧CP的成年人（其中11名被认为是视觉依赖性的成年人）和18名健康的成年人中，研究了视力依赖性作为影响动态性脑瘫（CP）患者功能稳定性发展的因素。在视野和支撑表面的俯仰平面扰动期间，参与者直立。通过将相邻身体段的轨迹拟合到椭圆形来评估段间协调行为。对椭圆取向角和面积进行混合模型重复测量方差分析。两组CP采取的不同稳定策略表明视觉依赖性会影响姿势控制。
