The purpose of this study was to verify the performance and suitability of new generation 3D wireless orientations sensors to measure cervical range of movement against a criterion standard instrument, an electromagnetic motion analysis system (Fastrak-Polhemus). The wireless orientation sensor (InertiaCube 3) consists of 9 motion-sensing elements: 3 accelerometers, 3 angular velocity rate transducers and 3 magnetometers. Measurements of cervical range of motion in each primary plane, left-lateral flexion, flexion and left rotation were directly compared front both systems in 10 normal asymptomatic subjects. Results showed very high cross-correlations (.99-.97) and low average root mean square errors (0.7-2.5 degrees). We conclude that orientation sensors are a valid, accurate and suitable device for obtaining cervical joint ranges of motion in the primary plane of movement. (c) 2006 Elsevier Ltd.
