Yergason's Test |
Examination type |
Tendonous
pathology, ligamentous integrity |
Patient & Body Segment Positioning |
Sitting
comfortably with the arm stabilized next to chest while the
elbow is flexed to 900 and the forearm is pronated.
|
Examiner Position |
The examiner
should be standing in front of the patient. The examiner should
have one hand placed on the volar aspect of the hand to resist
the patient when moving into supination and external rotation.
The other hand should palpate the biceps tendon in the bicipital
groove. |
Tissues
Being Tested |
llong head
of the biceps tendon, transverse humeral ligament |
Performing the Test |
The patient
will be instructed to supinate the forearm and externally rotate
the shoulder while the examiner resists the full range of
motion. |
Positive Test |
Localized
pain over the bicipital groove of the humerus; palpation yields
a feeling of the biceps tendon “popping out” of the bicipital
with resisted motion |
Interpretation |
Subluxation
of the biceps tendon indicates that the transverse humeral
ligament has been torn. Pain during this test with no
subluxation of the tendon may indicate bicipital paratendonitis
or tendinosis. |
Common errors in
performing exam |
Not giving
enough resistance to the patient during the full range of motNot
giving enough resistance to the patient during the full range of
motion; not correctly palpating the bicipital groove |
Factors possibly
resulting in misinterpretation |
Not as
effective as Speed’s test because only a small part of the
tendon is affected and biceps tendon pain usually occurs with
motion or palpation rather than tension produced in this test. |
