Relocation (Jobe) Test |
Examination type |
Joint
Instability |
Patient & Body Segment Positioning |
Lying
supine, shoulder abducted to 90 degrees with elbow flexed 90
degrees |
Examiner Position |
At the head of patient. Right hand under the
shoulder. Left hand on the wrist
Standing
next to the patient on the involved side. One hand on the
anterior aspect of the involved shoulder to apply a posterior
force to the humeral head while the other hand is on the elbow
of the involved side to externally rotate the shoulder. |
Performing the Test |
An
apprehension test is performed first to determine the presence
of pain or apprehension with external rotation of the shoulder.
Next the relocation test is performed with the examiner applying
a posteriorly directed force to the humeral head while
externally rotating the patients arm. |
Tissues
Being Tested |
Humeral head
in the glenoid fossa, anterior rotator cuff muscles |
Positive Test |
A decrease
in pain or apprehension when posterior force is applied to the
humeral head |
Interpretation |
Indicates
anterior shoulder instability |
Common errors in
performing exam |
Not applying
a posterior force to the humeral head; not externally rotating
the shoulder far enough to reproduce pain or apprehension while
applying a posterior force to the humeral head; externally
rotating the shoulder quickly without applying a posterior force
to the humeral head may make the humerus dislocate |
Factors possibly
resulting in misinterpretation |
No pain
reduction during the relocation test may indicate
acromioclavicular impingement. |
