What is the primary method to assess for a rotator cuff injury?

The primary method to assess for a rotator cuff injury is through palpation. This technique allows the clinician to feel for any abnormalities, tenderness, swelling, or specific areas of pain that indicate a problem with the rotator cuff tendons or muscles. By applying pressure and feeling around the shoulder joint, the practitioner can identify points of discomfort that may suggest an injury.

While visual inspection, passive range of motion, and functional testing are important components of a comprehensive shoulder examination, they do not provide the same level of detail for assessing soft tissue injuries like those involving the rotator cuff. Visual inspection might identify gross deformities or limitations, but it cannot assess tenderness or localized pain. Passive range of motion tests the joint's overall movement capabilities but does not specifically target the rotator cuff muscles or tendons. Functional testing is useful to observe how the shoulder performs during activities but may not pinpoint specific injuries.

Thus, palpation is a critical step in diagnosing rotator cuff injuries, enabling the healthcare provider to gather valuable information about the condition of the shoulder's soft tissues.
