4. DiscussionOur results indicate that elbow and wrist kinematics can be calculated for extended durations (>30 min) using solely angular velocity and linear acceleration measurements from IMUs with RMSE <4.7° for a given motion plane for various motion speeds (i.e., dowel transfer rates). As hypothesized, for a given sensor fusion algorithm, (i) measurement accuracy improved with increased motion speeds and (ii) RMSE was smaller for the wrist than the elbow.
