Inter-rater reliability of scapular dyskinesis classification in overhead athletes by entry-level physical therapy students.

Background: Scapular dyskinesis (SD) is a dysfunction associated with shoulder pathologies in overhead athletes and its classification is highly complex, especially in entry-level physical therapy students.

Objective: This research aimed to determine the effect of a video training method on inter-rater reliability of physical therapy entry-level students with no clinical experience while performing SD ratings under 4-type, severity, and 'yes or no' criteria in overhead athletes.

Methods: A total of 49 overhead athletes were evaluated by video recordings in posterior view of lifting tasks.
