Preliminary tests of an Inertial Measurement Units based System for Spine mobility assessment in patients with Ankylosing Spondylitis

This paper presents the preliminary tests of a novel system prototype for the physical assessment of mobility in patients with Ankylosing Spondylitis (AS). The system combines multi-inertial sensors arrays with Kalman Filters-based pose estimation for monitoring spine mobility in patients with AS. This system allows detecting movements with more reliable information than the manual clinical evaluation.
