The aim of this study was to understand the role played by visual information on the development of verticality and postural stability in healthy children.
The study comprised 66 healthy children from 4.0 to 15.7 years of age. Postural performances were recorded with a TechnoConcept platform. At the same time, the children's perception of subjective visual vertical (SVV) was recorded while they adjusted a vertical fluorescent line, either in the dark or in the presence of perturbing visual stimuli. Two testing control conditions without an SVV task were also performed by all of the children: static posturographic recording with open eyes and closed eyes.
Postural measurements provided evidence of a correlation between the children's age and the tasks performed. Postural stability improved with age until eight to nine years, and SVV performance improved after 10-11 years. After these ages, postural and SVV capabilities did not change until at least 15 years of age.
Our findings suggest that the maturation of cortical and central processes involved in both the perception of verticality and in postural stability took place during childhood. However, maturation occurred later for vertical perception, which could imply delayed maturation of sensory integration processes.
本研究旨在了解视觉信息在健康儿童垂直性和姿势稳定性发展中所起的作用。
该研究纳入了66名4.0至15.7岁的健康儿童。使用TechnoConcept平台记录姿势表现。同时，在黑暗中或存在干扰性视觉刺激的情况下，当儿童调整一条垂直荧光线时，记录他们对主观视觉垂直（SVV）的感知。所有儿童还进行了两种无SVV任务的测试对照条件：睁眼和闭眼的静态姿势描记记录。
姿势测量结果证明了儿童年龄与所执行任务之间的相关性。姿势稳定性随年龄增长而改善，直至八到九岁，而SVV表现则在10 - 11岁后有所改善。在这些年龄之后，姿势和SVV能力至少在15岁之前没有变化。
我们的研究结果表明，参与垂直感知和姿势稳定性的皮质和中枢过程在儿童期发生成熟。然而，垂直感知的成熟发生得较晚，这可能意味着感觉整合过程成熟延迟。
