External Rotation
What is the primary action of the subscapularis muscle?
Internal rotation of the shoulder
Multiple Choice: Which test is used for the teres minor muscle? A) Lift-Off Test B) Hornblower’s Sign C) Drop Arm Test
B) Hornblower’s Sign
What position is the patient in for the empty can test?
Arm abducted to 90 degrees and internally rotated
True or False: A positive drop arm test indicates a rotator cuff tear.
True
What does a positive lift-off test indicate?
Weakness of the subscapularis muscle
Which rotator cuff muscle is tested with the internal rotation lag sign?
Subscapularis
Fill in the blank: The __________ test is performed by having the patient raise their arm to 90 degrees and then externally rotate against resistance.
External Rotation
What is the primary purpose of manual muscle testing for the rotator cuff?
To assess the strength and function of the rotator cuff muscles
Multiple Choice: Which muscle is NOT part of the rotator cuff? A) Supraspinatus B) Biceps Brachii C) Subscapularis
B) Biceps Brachii
True or False: Manual muscle tests can help diagnose tears in the rotator cuff.
True
What is the clinical significance of the hornblower’s sign?
It indicates weakness in the teres minor muscle.
Fill in the blank: The __________ test assesses the supraspinatus muscle’s ability to abduct the arm.
Empty Can
Which rotator cuff muscle assists in externally rotating the arm?
Infraspinatus and Teres Minor
What does a negative lift-off test suggest?
Normal function of the subscapularis muscle
Multiple Choice: Which test requires the patient to place their hand behind their back? A) Empty Can Test B) Lift-Off Test C) External Rotation Test
B) Lift-Off Test
True or False: The drop arm test is specifically designed to test the strength of the subscapularis.
False
What does a positive external rotation lag sign indicate?

Lower
Which manual muscle test is particularly useful for assessing rotator cuff tears in overhead athletes?
