Abstract

The CODA 3-D motion analysis system has evolved from initial design studies which were carried out in 1970. This paper traces the history of the technical evolution of the system from the setting of the first design criteria to its present commercial form. Attention is paid to the way in which the design was affected by advances in available technology and perceived user need over this timescale. The operating principles of the current system are described in detail and related in quantified form to the performance specifications. The contributions of various types of measurement error, both intrinsic and extrinsic to the system are analysed. Integration of 3-D movement tracking with force platform output and EMG to provide a full biomechanics measurement and analysis capability is described. Applications of the system in clinical measurement are described and typical data presented.
