THE MOTION ANALYSIS SYSTEM AND THE MAXIMAL AREA OF FINGERTIP MOTION -A PRELIMINARY-REPORT

We have used the motion analysis system to evaluate the maximal area o f fingertip motion, Some modification in setting the cameras and use o f a smaller marker is required. In this series, 58 examinations have b een accomplished on 28 fingers with various traumatic injuries. The cl osed curve derived from the motion analysis system and the area calcul ated from it were easier to interpret and could be compared in serial examinations. A high linear correlation between the fingertip motion a rea and total active motion was found. The computer-aided motion analy sis system complements the traditional methods of assessing an injured finger.
