Stage 2 shoulder impingement most commonly occurs in which age range?

• A. 60+
• B. 25-40
• C. 15-24
• D. 41-60

Answer: (B)

Stage 2 impingement represents a transitional, chronic form of rotator cuff and subacromial tissue change, where fibrosis and tendinopathy develop after ongoing irritation. This pattern tends to appear in middle-aged adults who have had months of overhead or repetitive shoulder use, making the 25–40 age range the typical window. Younger patients are more prone to Stage I, with acute edema/hemorrhage, while patients over 40 are more likely to have Stage III changes, including cuff tears and more degenerative pathology. So the 25–40 range best fits the common presentation of Stage 2 impingement.
