概括
视力障碍 (VI) 和听力障碍 (HI) 的儿童表现出不同的平衡恢复策略. VI儿童更多地依赖部摆动,而HI儿童则利用脚策略,与典型的发育同龄人不同.
科学领域:
- 生物力学 生物力学
- 发育儿科 发育儿科
- 发动机控制器的控制器
背景情况:
- 恢复平衡对于预防跌倒至关重要,特别是在有感官障碍的儿童中.
- 了解听力障碍 (HI) 和视力障碍 (VI) 儿童使用的具体策略对于有针对性的干预至关重要.
- 以前的研究还没有完全阐明这些儿科群体中独特的平衡恢复机制.
研究的目的:
- 研究和比较HI和VI儿童的平衡恢复策略与对照组.
- 在静态和扰乱平衡条件下分析动力学数据的差异.
主要方法:
- 一项涉及45名9至13岁儿童的横截面研究,分为HI,VI和对比组.
- 使用维康系统在静态和扰动后平衡任务中捕获的三维下半身运动数据.
- 用于数据分析的重复测量ANOVA (3x2,组x条件) 用于 p ≤ .05.05 的显著性设置.
主要成果:
- 两组之间在静态状态下脚关节摇摆没有显著差异.
- 与比较组 (p = .001) 和HI (p = .02) 组相比,VI患者的孩子表现出更大的关节摆动.
- 在扰动后的条件下,VI儿童在平衡恢复方面表现出比HI和对照组 (p = .001) 更大的部和脚摆动.
结论:
- 视力障碍儿童和典型发育的儿童主要使用部平衡策略.
- 听力障碍儿童似乎利用脚策略来维持和恢复平衡,与其他群体不同.
- 这些发现突显了HI和VI儿童独特的感觉运动适应,为量身定制的康复方法提供了信息.

01:01Neuroplasticity
560
Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.

01:25Learning Disabilities
187
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.
