Roos Test |
Examination type |
Neurological, Vascular integrity |
Patient & Body Segment Positioning |
The patient
is sitting or standing with both elbows bent to 900
of flexion and both shoulders in 900 of abduction and
with full external rotation. |
Examiner Position |
Standing or
sitting in front of the patient to observe. |
Tissues
Being Tested |
Subclavian
and axillary arteries and the brachial plexus |
Performing the Test |
The patient
should rapidly open and close both hands while in the position
described above for 3 minutes. |
Positive Test |
The
inability to maintain the test position, diminished motor
function of the hands, and /or loss of sensation in the upper
extremities are positive signs/symptoms. |
Interpretation |
A positive
test is indicative of thoracic outlet syndrome, secondary to
neurovascular compromise. This test evaluates both neural and
vascular structures and is considered to be the most accurate
clinical test for assessing thoracic outlet syndrome. |
Common errors in
performing exam |
Do not test
for more than 3 minutes. Discontinue the test if positive signs
or symptoms are observed before the 3 minutes are up. |
Factors possibly
resulting in misinterpretation |
Underlying
shoulder or elbow pathology may make this test difficult to
perform. The hands may become cold, but this is not necessarily
due to injury. |
