A SYSTEMATIC REVIEW OF THE METHODOLOGIES USED TO VALIDATE INERTIAL SENSORS FOR JOINT ANGLE ESTIMATION

Abstract

Joint angle measurements are used extensively by clinicians and researchers alike, such measures have been employed to quantify both neutral and no-neutral postures, to assess the degree of impairment, to plan rehabilitation strategies, and to assess the effect of various interventions. Conventional systems of joint angle estimation (goniometers) are often straightforward to use, but they may not provide the full range of data that is needed. Addionally, goniometers provide information in single planes and only for static positions. Besides, these systems are not suitable for use in uncontrolled environments due to their lack of portability and the technical expertise required. This may limit their potential research applications. As a result, it can be challenging for researchers to obtain data about three-dimensional body segment postures.
