The Motion Analysis System and The Maximal Area of Fingertip MotionA Preliminary ReportFrom the Section of Plastic Surgery, Department of Surgery and the Institute of Biomedical Engineering of the National Cheng-Kung University, Tainan, Taiwan, Republic of China Correspondence: H-Y. Chiu, MD, Section of Plastic Surgery, Department of Surgery, National Cheng-Kung University, 138 Sheng-Li Road, Tainan, Taiwan, Republic of China. We have used the motion analysis system to evaluate the maximal area of fingertip motion. Some modification in setting the cameras and use of a smaller marker is required. In this series, 58 examinations have been accomplished on 28 fingers with various traumatic injuries. The closed curve derived from the motion analysis system and the area calculated from it were easier to interpret and could be compared in serial examinations. A high linear correlation between the fingertip motion area and total active motion was found. The computer-aided motion analysis system complements the traditional methods of assessing an injured finger.
