Purpose
[edit | edit source]
The purpose of the O'Brien Active Compression test is to indicate potential labral (SLAP Lesion)or acromioclavicular lesions as cause for shoulder pain.
Technique
[edit | edit source]
With the patient in sitting or standing, the upper extremity to be tested is placed in a positon of 90° of shoulder flexion and 10° of horizontal abduction. The patient then completely internally rotates at the shoulder and pronates at the elbow. The practitioner then provides distal stabilizing force as the patient is instructed to apply upward force. The procedure is then repeated in a shoulder and forearm neutral position. A positive test occurs with pain reproduction or clicking in the shoulder with the first position and reduced/absent with the second position. Depth of symptoms must also be assessed as superfiscial pain likely indicates acromioclavicular joint symptoms and deep pain is more likely labral symptoms.[1]
Evidence[edit | edit source]
The Sensitivity and Specificity of the Acitve Compression Test of O'Brien have been reported to vary widely and it has been reported that no one test that can accurately diagnose SLAP Lesions[3]. Studies have shown O'Brien's test to have a Specificity that ranges from 28% - 73% and a Sensitivity of 63% - 94% [4][5] .
However, when grouped with other tests for SLAP lesions such as the Crank, Anterior Apprehension and one of either Biceps Load II, Speed's, or Yergerson's the overall Sensitivity to be 75% and Specificity to be 90%[6].
| Sensitivity | 0.41 - 1.00 |
| Specificity | 0.95 - 0.97 |
| Positive Likelihood Ratio | 8.2 - 33.3 |
| Negative Likelihood Ratio | 0.00 - 0.62 |
| Sensitivity | 0.63 - 1.00 |
| Specificity | 0.73 - 0.98 |
| Positive Likelihood Ratio | 2.30 - 50.0 |
| Negative Likelihood Ratio | 0.00 - 0.51 |
