| Summary: | 碩士 === 國立成功大學 === 醫學工程學系 === 86 === 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.
