Ambulatory measurement of the scapulohumeral rhythm: Intra- and inter-rater reliability of a protocol based on inertial and magnetic sensors

A new protocol has been recently proposed to measure the coordinated movement of humerus and scapula, through an inertial & magnetic measurement system, in ambulatory settings. Since the protocol requires the intervention of a rater, the aim of this study was to assess its intra- and inter-rater reliability. Results for the coefficient of multiple correlation showed a reliability of the protocol ranging from 0.84 to 1, thus supporting its use for clinical assessment. © 2010 The authors and IOS Press.
