What tests are used to diagnose a rotator cuff injury?

Internal Medicine

A rotator cuff injury is typically diagnosed through a combination of a physical exam and imaging tests. During the physical exam, a doctor assesses shoulder strength, range of motion, and pain response. Imaging tests such as an MRI or ultrasound are then used to confirm the diagnosis, revealing tears, inflammation, or other damage to the tendons and muscles of the rotator cuff. X-rays may also be ordered to rule out bone-related issues like arthritis or fractures.

If you're experiencing shoulder pain, weakness, or limited mobility, don't wait to find answers. A free, instant, online symptom check can help you better understand what may be causing your discomfort and guide you toward the right next steps—whether that means seeing a specialist, getting imaging, or exploring at-home care options. Early insight can make all the difference in preventing further injury and speeding recovery.

Explanation

To diagnose a rotator cuff injury, doctors first perform a physical exam. During this exam, they may ask you to move your arm in different ways to see what hurts or feels weak. They might also press on certain spots to check for pain.

In addition to the physical exam, doctors often use imaging tests to get a better look at the shoulder. MRI (Magnetic Resonance Imaging) and ultrasound are common tests that help doctors see the muscles and tendons in the shoulder. These tests can show if there is a tear or other damage in the rotator cuff.

Sometimes, doctors use special tests during the physical exam that are designed to check for specific problems in the rotator cuff. These tests can help pinpoint the exact issue.
