This paper presents a different approach of recording and analysing human motion. The method involved utilizing electrogoniometer (biometrics, UK) to obtain the joint angles throughout the motion and by using Dual Euler angles and Dual Euler velocity analysis, the location and velocity of the measured segment or endeffectors can be estimated. Using golf swing as a basis of study, this paper explores the possibility measuring the anatomical rotations and quantifies the golf swing. The segmental anatomical rotations were recorded as: shoulder (anteversion/retroversion; external/internal rotation; abduction/adduction), elbow (flexion/extension), forearm (pronation/supination), wrist (flexion/extension; radial/ulnar abduction). The results are then processed to illustrate the arm movement and the swing path of the club. Copyright © 2004 SAE International.
