正常年輕人手部兩點分辨距與辨識能力的關係：初步研究

Abstract

The purpose of this study was to evaluate the difference of the distance of two point discrimination between distal and proximal areas in hands and the correlation between the performance of functional discriminative activity and the distance of two point discrimination.The moving and static two point discrimination distances of bilateral hands were measured in thirty normal young college students. Each of them performed the tests of functional discriminative activity by searching red-beans mixed in a container of rice and recognizing the numbers (from zero to nine) engraved on ten rubber stamps. The results revealed that (1) The distance of two point discrimination in hand is shorter at distal areas than proximal. (2) There is no positive correlation between the performance of functional discriminative activity and the distance of two point discrimination. (3) The scores of functional discriminative activity performance are better at the second time than the first. (4) There is no significant difference between the dominant and non-dominant hand in the performance of functional discriminative activity. It was revealed that sensory training by means of repetitive practice may be effective. The mechanism of the effect was due to central processing of perception in the brain and bilateral integration rather than peripheral procedure.
