The hug-up test, empty can (EC) test, full can (FC) test, Neer impingement sign
, and Hawkins-Kennedy impingement sign
were used and compared statistically for their accuracy in terms of supraspinatus tears, with arthroscopic findings as the gold standard.
Patients who show positive Hawkins-Kennedy test & Neer impingement sign
Tests on the right shoulder showed positive result for Neer impingement sign
, Empty Can test, Hawkins Kenedy test and Speed test.
2) Investigators assessed 8 physical exam tests--the Neer impingement sign
, Hawkins-Kennedy impingement sign
, painful arc sign, supraspinatus muscle strength test, Speed's test, cross-body adduction test, drop-arm sign, and infraspinatus muscle strength test--to determine their diagnostic utility.

, Hawkins-Kennedy test, Painful arc syndrome, Yocum manoeuvre.
Magnetic resonance (MR) imaging of seven volunteers with no history of shoulder instability demonstrated contact between the greater tuberosity and posterosuperior glenoid rim in all seven with the arm in full shoulder elevation and internally rotation, mimicking the impingement sign
Multidirectional instability may present with pain and impingement signs
, without obvious feeling of instability.
Burnett and coworkers (7) also found that 95% of their cohort with labral pathology had positive impingement signs
and lower rates of symptoms, such as a limp or a Trendelenburg sign.
At their 6-month follow-up examinations, the patients' Harris hip scores had recovered from 64 to 100 (Case I) and from 50 to 98 (Case II), and the anterior and posterior impingement signs
were negative in both cases.
Acromioplasty must be performed only when there are clinical or intraoperative impingement signs
The clinical examination can be difficult because impingement signs
can mimic acromioclavicular joint signs or an early frozen shoulder, so a directed injection of local anaesthetic into the area that appears to be the mostly likely origin of the pain can be the most important diagnostic tool.
18) We also tracked the hips with radiographic impingement signs
(on the resurfacing side) and measured the acetabular component abduction angle.
