Current evidence is not sufficient to recommend any of the 31 measurement instruments related to scapular posture, movement, and dyskinesis.
The quality of evidence for the criterion validity of measurements of scapular protraction/ retraction and rotation up to 120 degrees is sufficient, however that of scapular posture, range of motion, and lateral slide is insufficient.
Other measurements showed even lower evidence quality. Measurements of scapular dyskinesis were especially prone to misinterpretation.
