 Typically the SHR is given as the ratio of the glenohumeral abduction angle and the scapula medio-lateral rotation angle during humeral abduction movements (movement mainly in frontal or scapula plane). In many publications, due to technical reasons, the glenohumeral abduction angle is determined from the thoracohumeral abduction angle by subtracting the scapula medio-lateral rotation angle. All of these angles can be defined by cardan sequences or by projection angles. Typically the SHR is given as the ratio of the glenohumeral abduction angle and the scapula medio-lateral rotation angle during humeral abduction movements (movement mainly in frontal or scapula plane).

 This is a different measure, which results in different numerical values, for the so called SHR ratio but it is robust against angle-offsets. A numerical feature of this definition is, that it can be implemented a way that the measure does not depend on the rotation order of the cardan angles. This is a different measure, which results in different numerical values, for the so called SHR ratio but it is robust against angle-offsets.
