Chronic whiplash associated disorders and neck movement measurements: an instantaneous helical axis approach

IEEE Trans Inf Technol Biomed. 2003 Dec;7(4):274-82. doi: 10.1109/titb.2003.821328.

Abstract

This paper presents an assessment tool for objective neck movement analysis of subjects suffering from chronic whiplash-associated disorders (WAD). Three-dimensional (3-D) motion data is collected by a commercially available motion analysis system. Head rotation, defined in this paper as the rotation angle around the instantaneous helical axis (IHA), is used for extracting a number of variables (e.g., angular velocity and range, symmetry of motion). Statistically significant differences were found between controls and subjects with chronic WAD in a number of variables.
