Starting Position

This test can be performed with the patient in standing or sitting. The examiner supports the patient’s arm to be tested and abducts it to 90 degrees. Alternatively, the examiner may abduct the arm to above 90 degrees, possibly even to full abduction. Another variation is to have the patient actively abduct their arm to the starting position.

Test Movement

The patient is asked to actively lower their arm from abduction to their side in a slow and controlled manner.

Positive Test

A positive test is determined by the patient’s inability to smoothly control the lowering of their arm or the inability to hold the arm in 90 degrees of abduction. In a positive test that starts above 90 degrees of abduction, the patient will tend to have difficulty controlling the movement around 90 degrees of abduction. There may or may not be pain reported. Pain alone is not a positive test.

Accuracy of Test

The test accuracy is high.

  • Interexaminer reliability: 0.65-0.78
  • Specificity: 96%
  • Sensitivity: 24%
  • Likelihood ratio: 6.45
