TY - JOUR AU - Challis, John H. PY - 2020 DA - 2020/03/23 TI - Quaternions as a solution to determining the angular kinematics of human movement JO - BMC Biomedical Engineering SP - 5 VL - 2 IS - 1 AB - The three-dimensional description of rigid body kinematics is a key step in many studies in biomechanics. There are several options for describing rigid body orientation including Cardan angles, Euler angles, and quaternions; the utility of quaternions will be reviewed and elaborated.
