Abstract
The wrist plays a vital yet frequently overlooked role in positioning and supporting the hand during activities of daily living. Particularly during low-level activities (such as typing), passive joint stiffness dominates wrist dynamics and constitutes the main obstacle to motion. In spite of its importance, however, little consensus exists as to the exact range of passive wrist stiffness. Reported values vary from as little as 0.002 Nm/rad (Lehman & Calhoun, 1991) to as many as 9.0 Nm/rad (Crisco et al, 2010), a span of three orders of magnitude! The purpose of this research is to determine an approximate single-order-of-magnitude range for passive wrist stiffness (Nm/rad) in the four cardinal directions using as many independent techniques as possible.
