在22名痉挛性双侧脑瘫（CP）成人（其中11人被认为是视觉依赖）和18名健康成人中研究了视觉依赖作为影响脑瘫（CP）患者功能稳定性发展的因素。参与者在视野和支撑表面的俯仰平面干扰期间直立。通过将相邻身体节段的轨迹拟合成椭圆来评估节段间协调行为。对椭圆方向角和面积进行混合模型重复测量方差分析。两组CP患者采用的不同稳定策略表明视觉依赖影响姿势控制。在所有组中，对视觉流的姿势重组表明，在设计治疗干预措施时，我们不能忽视姿势控制的感知方面。
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.
