How to Tell If You Have a Rotator Cuff Tear or Shoulder Impingement

rotator-cuff-Precizion-Performance-Lab-Rancho-Cucomonga-CA-banner

Shoulder pain can feel like a roadblock, especially for baseball and softball players. Are you worried about a rotator cuff tear or unsure if it’s just impingement? You’re not alone. As a double board-certified sports physical therapist, I’m here to guide you through the key signs and at-home tests to help you better understand your shoulder pain and take the next steps toward recovery.


What Are Rotator Cuff Tears?

The rotator cuff is a group of muscles and tendons in your shoulder, and injuries to it generally fall into two categories: partial tears and complete tears. Here’s a simple breakdown:

  • Partial Tear: Damage to the muscle, but it’s still partially intact. This can range from small to massive tears. Pain tends to be consistent.
  • Complete Tear: The muscle is fully torn, often due to significant trauma. While this can cause severe pain initially, it may fade, leaving behind noticeable weakness.

Quick Analogy: Think of a sheet of paper. A partial tear is like a small slice or rip, while a complete tear is tearing the sheet in half.


At-Home Tests for a Rotator Cuff Tear

Here are three simple tests you can try to check for a rotator cuff tear:

1. Drop Arm Test

  • Lift your arm straight out to the side.
  • Slowly lower it back down.

Results: If your arm drops uncontrollably, it might indicate a tear, especially in the supraspinatus muscle.

2. External Rotation Test

  • With your arm at your side, rotate it outward and hold the position.

Results: If your arm feels weak or snaps back even slightly, you may have a tear in the infraspinatus or teres minor.

3. Lift-Off Test

  • Place your hand on your lower back and try to lift it off.

Results: If you can’t lift your hand or it’s extremely painful, this might point to a tear in the subscapularis.


How to Spot Shoulder Impingement

Shoulder impingement happens when the rotator cuff gets pinched during movement, leading to pain and reduced motion. Try these quick tests:

1. Painful Arc Test

  • Slowly raise your arm overhead.
  • Look for pain between 60 and 120 degrees that disappears as your arm continues upward.

Results: Pain in this range often signals shoulder impingement.

2. Empty Can Test

  • Raise your arm to shoulder height, thumb pointing downward, and resist pressure.

Results: Pain could suggest impingement or a rotator cuff issue.

3. Hawkins-Kennedy Test

  • Raise your arm to 90 degrees, bend your elbow, and have someone apply downward pressure.

Results: Pain here is another sign of shoulder impingement.


What to Do If You Suspect a Shoulder Injury

These tests can provide clues, but they’re not a substitute for a professional diagnosis. Persistent pain, weakness, or limited motion should be addressed by a physical therapist or orthopedic specialist.


Conclusion: What’s Next for Your Shoulder?

So, how can you tell if you have a rotator cuff tear or shoulder impingement? A combination of consistent pain, weakness, and these simple tests can point you in the right direction, but consulting a professional is essential to confirm the diagnosis.
