What is a Drop Arm Test?

The rotator cuff is a group of four muscles and tendons around the shoulder joint that provide stability, allowing for smooth and pain-free movement. It is incredibly important in everyday activities like reaching, lifting, pushing, and throwing.

Without healthy rotator cuffs, people can experience extreme pain and difficulty doing basic activities. Unfortunately, rotator cuff injuries are relatively common, especially among those who repeatedly perform overhead motions, like athletes and construction workers.

Healthcare professionals often use a to assess the stability of the rotator cuff and test for potential injury. This simple physical exam involves having the patient raise their arm and see if they can lower it without support.

The Drop Arm Test requires the patient to raise their arm to 90 degrees and slowly lower it. The clinician will observe if the patient has difficulty lowering the arm, which could indicate rotator cuff injury. A positive result is when the patient's arm drops to less than 90 degrees or they cannot lower it.

How does this printable Drop Arm Test work?

Our free printable Drop Arm Test guide includes an explanation and thorough instructions for performing the test. Follow these steps to get started:

Step One: Access the free template

Use the link on this page to download our free Drop Arm Test worksheet. You can also access it using the Carepatron app or the resources library.

Step Two: Discuss the test with your patient

Explain the Drop Arm Test to the patient and explain why you are performing it. Ensure they understand that discomfort may be felt during the test, but it should not be too painful.

Step Three: Administer the exam

Ask the patient to raise their arm to 90 degrees. Have them slowly lower it and observe how far they can bring down the arm without support. If the arm drops to less than 90 degrees or cannot be lowered at all, this is considered a positive result.

Step Four: Document and interpret the results

Write down the results in the provided worksheet. If a positive result is found, further evaluation may be needed to diagnose rotator cuff injury.

Drop Arm Test Interpretation

This simple physical exam can be used to assess shoulder instability and identify any potential rotator cuff injury. A positive Drop Arm Test result could indicate a tear or strain in the rotator cuff, and further evaluation may be needed. Ultimately, this test should NOT be used to diagnose any injury or condition, as it is only a simple and initial assessment.

When to use these Arm Drop tests?

The Drop Arm Test is typically used when clinicians assess a patient for rotator cuff injury or instability. It can also be used to:

Track and monitor the healing process for rotator cuff injury

The Drop Arm test can assess shoulder stability and observe the healing process after a rotator cuff injury. This can be done by performing the test regularly and noting changes throughout your patient’s treatment journey.

Measure improvement or worsening of injury symptoms

The Drop Arm Test can track the progression of rotator cuff injury and compare results over time. It can help you monitor any improvement or worsening of symptoms.

Compare the strength, stability, and range of motion of both arms

By administering this assessment, you can compare both arms' strength, stability, and range of motion. It can help you determine if an imbalance exists, which can indicate rotator cuff injury.

Assess shoulder flexibility or tightness

The shoulders are one of the most flexible parts of the body, and maintaining flexibility is important for overall mobility and healthy joints. Using the exam, you can evaluate your patient’s shoulder flexibility or tightness and take the necessary steps to improve it.
