Comparison of methods of measurement of head position in neurological practice

Abstract

In this paper we describe advanced methods for the precise posture head measurement and explain our method of non-invasive head position measurements by cameras and accelerometers. The methods are designed for use in neurology to discover relationships between some neurological disorders (such as disorders of vestibular system) and postural head alignment. The main goal of this study is to compare possibilities of the methods. The results are presented for rotation and flexion of head. It was experimentally checked that the accuracy of this method in order of tenths of degrees and therefore this method satisfies the general physicians' requirement for the accuracy of the measurement about 1-2°. © 2010 International Federation for Medical and Biological Engineering.
