Abstract

Externally-mounted instrumented spatial linkages (ISL's) are often the device of choice for total six degree of freedom (DOF) anatomical motion measurement in the research lab, and they are being considered for use in the clinical setting. ISL's can accurately measure the six DOF motion of the anatomical joint without imposing any motion constraints on the joint. They are among the best devices to quantitatively measure relative motion considering accuracy, portability, and cost. Also, motion data is processed automatically and quickly. However, there is little available guidance in choosing appropriate ISL design parameters for particular applications. The goal of this study is to develop methods for design of ISL's to measure a certain range of anticipated anatomical joint positions with minimal error.
