This study tested whether a new visual clinical test could reliably detect abnormal scapular motion in overhead athletes. The Scapular Dyskinesis Test uses weighted shoulder flexion and abduction to classify each scapula as normal, subtle, or obvious dyskinesis. The question: can trained clinicians agree on what they see?
When you evaluate an overhead athlete with shoulder pain, you need a repeatable way to decide whether scapular control is a problem worth treating. This paper gives you that tool. The SDT collapses assessment to a single clinical question: is there dyskinesis (winging or dysrhythmia), yes or no?
The key teaching point is that asymmetry is not the same as dysfunction. Asymptomatic athletes frequently show side-to-side scapular differences, so you rate each scapula against the thorax, not against the other side.
Remember two testing principles: load the arm and use flexion. Weighted tasks and the eccentric lowering phase expose dyskinesis that static exams miss, and weighted flexion is the most provocative movement. This is a reliability study only. It proves clinicians can agree on what they see, not that dyskinesis causes injury or that treating it changes outcomes. Part 2 addresses validity.
