Irritation or entrapment of the lower subscapular nerve, which innervates the subscapularis and teres major muscles, will produce muscle guarding at the shoulder that will restrict motion into external rotation, abduction, or flexion.

"External rotation " ( or " extorsion " or " lateral rotation " ) is an anatomical term of motion referring to rotation away from the center of the body.

Fourth-year students train full-time in clinical rotations locally and throughout the United States . ( Training for each fourth-year student must include an external rotation at a Veterans Administration medical center .)

The tests differ in the rotation of the arm; in the Empty can test, the arm is rotated to full internal rotation ( thumb down ) and in the Full can test, the arm is rotated to 45?external rotation.

Badminton biomechanics have not been the subject of extensive scientific study, but some studies confirm the minor role of the wrist in power generation and indicate that the major contributions to power come from internal and external rotations of the upper and lower arm.

Mechanical measurements that are assessed include, but are not limited to, foot position at stride foot contact ( SFC ), elbow flexion during arm cocking and acceleration phases, maximal external rotation during arm cocking, horizontal abduction at SFC, arm abduction, lead knee position during arm cocking, trunk tilt, peak angular velocity of throwing arm and angle of wrist.

For the diagnosis of impingement disease, the best combination of tests were " any degree ( of ) a positive Hawkins-Kennedy test, a positive painful arc sign, and weakness in external rotation with the arm at the side, " to diagnose a full thickness rotator cuff tear, the best combination of tests, when all three are positive, were the : " the painful arc, the drop-arm sign, and weakness in external rotation ".
