Question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): Upper back postural correction exercises and scapular stabilization exercises are readily prescribed for the management of secondary shoulder impingement.
Reason (R): Glenohumeral instability can also lead to the development of impingement syndrome at shoulder.
In the light of the above statements, choose the most appropriate answer.

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

Secondary impingement = Instability problem Treat with stabilization + posture correction

Answer 1

The Correct Option is A

Concept:
Secondary shoulder impingement is primarily caused by:
• Muscle imbalance
• Poor posture
• Glenohumeral instability It is not due to structural narrowing alone (as in primary impingement), but due to functional instability.

Step 1: Understanding Assertion (A).
Management of secondary impingement includes:
• Postural correction exercises (especially upper back)
• Scapular stabilization exercises These help:
• Improve scapular mechanics
• Reduce abnormal stress on shoulder structures Thus, Assertion (A) is correct.

Step 2: Understanding Reason (R).
Glenohumeral instability:
• Leads to abnormal humeral head movement
• Causes impingement of soft tissues Thus, Reason (R) is correct.

Step 3: Linking A and R.
Because instability causes impingement:
• Stabilization exercises are prescribed
• Postural correction reduces faulty biomechanics Hence, Reason explains Assertion.

Step 4: Conclusion.
\[ \boxed{\text{Both A and R are correct and R explains A}} \]
