How accurate is the drop arm test?
The drop arm test had a specificity of 96% (95% CI=93%–100%), sensitivity of 24% (95% CI=14%–34%), and likelihood ratio of 6.45 (95% CI=2.25–18.47). Diagnostic accuracy values for other tests are provided in Tables 2 and 3.
What does a positive drop arm test indicate?
Severe pain or inability of the patient to return the arm to the side slowly indicates a positive test result. A positive result indicates a rotator cuff tear.
Which special tests of the shoulder have been shown to have the highest sensitivity and specificity?
The Supraspinatus test for any full thickness rotator cuff tear obtained the highest DOR of 9.24 (sensitivity was 0.74, specificity 0.77).
What is a positive Hawkins-Kennedy test?
A positive Hawkins-Kennedy test is indicative of an impingement of all structures that are located between the greater tubercle of the humerus and the coracohumeral ligament. The impinged structures include the supraspinatus muscle, teres minor muscle, and the infraspinatus muscle.
What shoulder special test is 75% accurate?
Shoulders were then examined by high resolution MRI with 95% accuracy for full thickness tears of the supraspinatus tendon. There were 35 shoulders with full thickness tear of the supraspinatus tendon….Research.
| Sensitivity | Specificity | Accuracy |
|---|---|---|
| 77% | 74% | 75% |
| 86% | 57% | 64% |
| 63% | 77% | 89% |
| 55% | 68% | 50% |
How can you tell the difference between a frozen shoulder and a torn rotator cuff?
With a rotator cuff injury, your arm’s range of motion may be limited, but you can lift it manually. In contrast, a frozen shoulder is characterized by a dull or aching pain and a limited range of motion makes it difficult to lift the arm past a certain point.
Which shoulder special test is 75% accurate?
Can you have rotator cuff tear and frozen shoulder at the same time?
Many researchers and physicians have recently reported that rotator cuff (RTC) injuries can be quite common with frozen shoulder and some even believe that a RTC injury may be the cause of a frozen shoulder.
What’s the difference between frozen shoulder and impingement?
Frozen shoulder causes a person to not be able to turn their arm out and can be quite painful even when motionless and especially at night. While there is some overlap in symptoms, shoulder impingement is caused by a swollen rotator cuff. It causes pain in a certain range of motion.
The drop arm test is used to assess for full thickness rotator cuff tears, particularly of the supraspinatus. This can be useful when diagnosing sub-acromial pain syndrome ( shoulder impingment) or to differentiate between shoulder and rotator cuff pathologies. The drop arm test may be more accurate when used in a battery of tests such as:
What is the drop arm test for rotator cuff tear?
The drop arm test is used for diagnosing rotator cuff tendon tear, especially the supraspinatus tendon tear. This test helps in determining if there is a tear in the supraspinatus tendon. The rotator cuff is a common name for a group of 4 muscles and their tendons.
What is DropDrop arm test (drop sign)?
Drop Arm Test (or Drop Sign) is used to check for the integrity of the supraspinatus muscle of the rotator cuff of the shoulder. It’s sometimes called Codman’s test.
What does a negative drop arm test mean?
The drop arm test is considered positive when the patient cannot hold their arms at 90° of abduction or can not control the lowering of the arm to their side. The patient may also feel pain and weakness while lowering the arm. All these things indicate a massive supraspinatus tendon tear. Negative Drop Arm Test
