title: Clinical evaluation of acromioclavicular joint pathology: sensitivity of a new test.
abstract: BACKGROUND
  A prospective study was established to assess the sensitivity of the newly described Bell-van Riet (BvR) test for isolated AC pathology, and compare with 4 commonly used clinical tests.
  
  
  METHODS
  The BvR test is essentially the cross-adduction test, with the addition of attempted elevation against resistance. In a positive test, this results in some pain and the inability of the patient to maintain the arm in the adducted and elevated position against resistance. Fifty-eight patients with isolated AC joint symptoms were assessed in random order with the BvR test and 4 other tests. A corticosteroid and local anaesthetic injection was administered into the AC joint space. The BvR test and 4 other tests were then repeated following the injection. After the injection, a symptom free clinical examination was used as a measure of truly positive tests.
  
  
  RESULTS
  The BvR test showed a sensitivity of 98%. All 4 other tests were less sensitive.
  
  
  CONCLUSIONS
  The BvR test is a highly sensitive test in patients presenting with isolated AC related symptoms, and demonstrates AC joint pathology better than other accepted tests.
