Hawkins-Kennedy Impingement Test |
Examination type |
Tendon
impingement |
Patient & Body Segment Positioning |
Patient can
be either standing or seated with the involved arm help
passively in 900 of shoulder flexion with the elbow
flexed to 900. |
Examiner Position |
The examiner
will be standing beside the involved shoulder or in front of the
patient. One hand should support the elbow at the medial
epicondyle with the thumb on the lateral side of the humerus,
and the other hand should grasp the wrist of the involved arm. |
Tissues
Being Tested |
Tsupraspinatus
muscle tendon, anteroinferior border of acromion process |
Performing the Test |
Using the
hand at the elbow as a fulcrum, apply downward pressure to the
wrist. This movement internally rotates the humerus and causes
the humeral head to push the supraspinatus tendon against the
anterior surface of the coracoacromial ligament and coracoid
process. The test may also be performed in different degrees of
forward flexion (vertically “circling the shoulder”) or
horizontal adduction (horizontally “circling the shoulder”). |
Positive Test |
Pain present
in superior aspect of the shoulder |
Interpretation |
Impingement
of supraspinatus tendon or tendonitis |
Common errors in
performing exam |
The examiner
may be testing in the wrong position or have improper hand
placement. The examiner may also apply to much or not enough
force during internal rotation. Proper patient positioning of
the arm is important. |
Factors possibly
resulting in misinterpretation |
Other
possible injuries may interfere with the testing of the
supraspinatus such as muscular injury to the posterior deltoid,
infraspinatus, or teres minor or a posterior capsule sprain
(which will come into affect during internal rotation of the
shoulder). |
