Measurement of lower extremity kinematics during level walking
TL;DR: The relatively small number of body surface markers used in the VICON system render it easy to implement for use in routine clinical gait evaluations and should be a useful reference for describing and comparing pathologic gait patterns.

Repeatability of kinematic, kinetic, and electromyographic data in normal adult gait.
TL;DR: The results demonstrate that with the subjects walking at their natural or preferred spped, the gait variables are quite repeatable, and suggest that it may be reasonable to base significant clinical decisions on the results of a single gait evaluation.

A New Mathematical Formulation for Strapdown Inertial Navigation
TL;DR: In this article, a differential equation for the orientation vector relating the body frame to a chosen reference frame is developed, where the time derivative of this vector is the sum of the inertially measurable angular velocity vector and non-measurable non-commutativity rate vector.
