However, little is known about the relationship between this objective measure and patient-reported outcome measures assessing shoulder pain, function, and disability.

Participants completed the Spanish versions of the SST, SPADI, DASH, and Quick-DASH questionnaires. FRV was subsequently quantified using a Microsoft Kinect-based system during a standardized shoulder circumduction protocol.
