摘要

体位系统需要感觉系统维持体位控制。盲人使用体感系统来保持PC，而正常人使用视觉系统。那么当挑战感官系统时，PC会发生什么呢?我们分析了10名盲人和10名正常受试者在睁眼/闭眼(视觉系统干扰)和坚硬/泡沫表面(体感系统干扰)条件下的压力中心(COP)。我们发现，当眼睛在坚硬的表面上睁开时，盲人依赖于体感系统，而正常人依赖于视觉系统。然而，当眼睛闭上并在泡沫表面时，两组在所有COP变量中都发现了相似的行为。一般情况下，盲人受试者使用躯体感觉系统作为维持PC的主要感觉输入。

Effects of the Interference of Sensory Systems on Postural Control in Congenitally Blind Subjects.

The postural system requires the sensory systems to maintain postural control (PC). Blind subjects use the somatosensory system to keep PC whereas sighted subjects use the visual system. So what happens to PC when challenging the sensory systems? We analyzed the center of pressure (COP) in ten blind and 10 sighted subjects under conditions: eyes open/closed (interference of visual system) and on firm/foam surfaces (interference of somatosensory system). We found that under the condition of eyes open on a firm surface, the blind subjects relied on the somatosensory system, whereas sighted subjects relied on the visual system. However, when eyes closed and on foam surface, similar behavior was found in both groups for all COP variables. In general blind subjects use their somatosensory system as the main sensory input to maintain PC.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
