How are scapular and shoulder girdle mechanics different in a shoulder with SAI?
Limited superior rotation of scapula, limited posterior tilt, limited retraction
How are scapular and shoulder girdle mechanics different in a shoulder with PII?
Limited retraction of shoulder girdle
How are GH joint mechanics different in a shoulder with SAI?
Excessive anterior and superior humeral translation, limited LR
How are GH joint mechanics different in a shoulder with PII?
Excessive anterior humeral translation
Limited MR
Increased cross-extension use
Clinical presentation for SAI
-common in sports with repeated overhead motion
-pain can be intermittent or continuous, aggregated in impingement positions
Clinical presentation for PII
-typically associated with throwing athletes
-pain can be intermittent or continuous, found in posterior shoulder
-clicking may indicate labral tear
