This report describes a technique for recording range of motion of digital joints. The technique involves tracing digital outlines with an angled marker on a sheet of paper attached to a special interray pad. A complete dorsal silhouette of the entire ray can be obtained by mounting the pad and the paper astride the palm parallel to the ray of the digit being evaluated. Fabrication and use of the equipment is described. This silhouetting system could be an alternative to wire tracing in visualizing tendencies of dynamics of digital range of motion.
