Understanding normative values is essential for accurately restoring deltoid mechanics in pathological conditions; however, there is a notable lack of data on this topic, particularly with respect to objective measurement methods.

Twelve SWE measurements of the middle deltoid were obtained for each side (left/right) and shoulder position (resting at side and 90° abduction) using a standardized measurement technique. Measurements were performed by 4 independent operators with varying levels of training and experience in ultrasound measurement (2 expert and 2 novice operators). Intraoperator and interoperator reliability were assessed using the median values for each measuring position, side, and measurer.
