Explain the "trick movements" a patient with a ruptured supraspinatus tendon might use when raising their arm and why.

Hey جدة, good to see you again. A ruptured supraspinatus tendon is a common shoulder injury. The supraspinatus muscle is crucial for the initial 15 degrees of arm abduction (lifting the arm away from the body). When a patient has this injury and tries to raise their arm above their head on the affected side, they often use "trick-devices" to compensate: 1. They might tilt their body to the affected side, which causes the arm to swing away from the body, achieving an initial 15° of abduction. 2. Alternatively, they might use their healthy hand to slightly lift the affected arm by about 15°. These maneuvers help them bypass the painful or impossible initial abduction phase normally performed by the supraspinatus, allowing other muscles to take over for further arm movement.
