中文摘要 | 本研究之目的在探討正常人之(1)手部靜態與動態兩點分辨距離,其近端和遠端是否有差異。(2)功能性辨識能力是否與兩點分辨距成反比(3)先測手和後測後,及慣用手和非慣用手在兩項功能性辨識能力測驗之差異並探討其機轉。 本研究以30位正常年輕人,作兩手測試。先於手部所劃分之十九個區域中,測其兩點分辨距;再以兩項功能性辨識能力測驗,即以手指探索米粒堆中之紅豆及橡皮章所刻0-9的數字,每手各作三次測試。 結果顯示:(1)各指遠端之兩點分辨距(靜態與動態)皆小於近端。(2)兩項辨識能力測驗的成績與兩點分辨距之平均值並無有意義相關。(3)在兩項辨識能力的測驗中,後測手之得分優於先測手。(4)慣用手與非慣用手對於兩項辨識能力的測驗之得分,並無有意義之差異。顯示感覺訓練使用重覆練習是可能有效,其機轉係中樞處理化(central processing)過程及兩側統整後之經驗累積。 |
英文摘要 | The purpose of this study was to evaluate the difference of the distance of two point discrimination between distal and proximal area 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 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. |
