Safe self-observation

Apprehension awareness (do not provoke)

Recognise positions in which the shoulder feels it may slip—without testing them.

RED — seek emergency care

Never force a position to "test" instability at home—it can cause a dislocation.

Purpose	Recognise positions in which the shoulder feels it may slip—without testing them.
Procedure	Notice (do not deliberately reproduce) whether reaching out and turning the arm outward, or reaching overhead or across the body, makes you feel the shoulder could slip.
What you may notice	Apprehension in unstable positions is described for labral tears and instability.
Interpretation	Avoid provoking these positions; follow the Shoulder Instability protocol or seek assessment.
