We performed a subacromial impingement injection test by injecting 10 mL of a local anesthetic into the subacromial space in patients with positive impingement test
Medial rotation assessed in 90 degrees of flexion, the Hawkins' impingement test
(Hawkins and Bokor 1990), compresses both the subacromial and subcoracoid spaces.
41) Impingement may be a cause of persistent groin pain after hip resurfacing (42) and can be elicited during the physical examination using a provocative impingement test
that combines hip flexion, adduction, and internal rotation.
The slurry jet impingement test
results at the 900 impingement angle did not discriminate between the three alloys.
Additionally, it is well known that the impingement test with injection of 10 cc of 1% lidocaine into the subacromial space is useful in distinguishing impingement lesions from other causes of shoulder pain (11).
In this study, impingement test with lidokain injection was not used for the diagnosis of SIS, thus, in future trials this test can be performed besides other clinical assessments.
The only impingement test to produce a positive likelihood ratio above 10 or a negative likelihood ratio below 0.
Sensitivity, specificity, and likelihood ratios for impingement tests.
Hawkins (Hawkins and Kennedy, 1980) and Neer (Neer, 1983) impingement tests
were both very painful.
Specific impingement tests
as Neer, Hawkins, Whipple and Yocum were positive, digital compression of the OA site was painful, Jobe test for supraspinatus muscle was positive as were the palm-up test for long head of biceps, all only in the right shoulder.
The patients with positive impingement tests
(Neer, Hawkins-Kennedy, and painful arc tests) along with a positive SIT were diagnosed with primary SIS.
