What is the normal external rotation value in shoulder ROM?

• A. 90 degrees
• B. 60 degrees
• C. 120 degrees
• D. 45 degrees

Answer: (A)

External rotation of the shoulder is how far the arm can turn outward from the body. In standard clinical testing, the normal value is about ninety degrees, measured with the arm positioned in a consistent way (often with the elbow flexed and the arm at a specific angle). This ninety-degree reference is used as the benchmark for a typical, healthy shoulder. Values around sixty or forty-five degrees indicate reduced rotation, while a number like one hundred twenty degrees would suggest hypermobility or a different testing position. So, the normal external rotation value to recall is about ninety degrees.
