在諸多職業傷害、意外傷害或疾病中，手部傷害是最常見的一種。我
們已利用動態分析系統來評估手指的運動功能，包含完整的手指運動過程
關節角度之記錄與手指指尖運動範圍面積的定量評估，使得在診斷病情及
評估復健成果上，有足夠的資料及準確性。本文主要目的在(1)正常人的
重覆性測試(2)正常人資料庫的建立(3)病人的評估。 在重複性試驗中
，單一週內的ICC值介於0.92-0.94間，而三週間的ICC值為0.94，代表於
受測者對於手指運動範圍面積有很好的重複性。而於資料庫建立上，由於
手指運動範圍面積在性別、左右手、個別手指間並無交互作用，且彼此間
在統計學上並無明顯差異，所以我們可以得到一手指長度對應到手指指尖
運動範圍面積的迴歸方程式Area=0.67*(length)2。 而病人利用手指
運動範圍面積來評估手指運動功能(FM)與美國醫學會(AMA)指標所評估出
之手指運動功能有很高之相關性(R=0.889)，而在於部份手指壓碎傷之病
人FA評估出的功能值較FM好，這是由於病人手指各單一關節已經有相當的
彎曲能力，但在手指各關節間的配合能力並不好，導致有此結果。

We evaluate the finger motor function by measuring the area
of the range of motion of fingers from using a 3-dimensional
motion analysis system. The purposes of this study are 1) to
test reliability and repeatability of the area measurement of
normal subjects, 2) to establish a fingertip motion areadatabase
of normal subjects, and 3) to clinicallyevaluate the impairment
of fingers for patients. Ten health subjects had been tested
by repeatedmeasurements three times, once in a week and last for
three weeks. The between-week ICC was 0.94. Thewithin-week ICC
was from 0.92 to 0.94. This resultmeant excellent reliability in
our test. Normal data base was established from twenty health
subjects.By 3-way ANOVA, there is no interaction in sex, hand
and finger. And there are no significant differences in male/
female, left/right hand and different fingers. So, we used non-
linear regression to calculate regressive function between
finger length and area. This result is Area=0.677*length2. After
evaluating twenty patients, there is high correlation, R=0.889,
between our method with AMA(American Medical Association)
standard. Our method for evaluation of finger motor
functionmaybe better than others. The main reason is that a
large area of fingertip motion includes not only larger range of
finger joint angles, but also better coordination of finger
joints.
