Halstead's Test |
Examination type |
Neurological, Vascular integrity |
Patient & Body Segment Positioning |
The subject
should be seated and relaxed. |
Examiner Position |
The examiner
stands behind the athlete and palpates the radial pulse on the
involved side throughout the test. |
Tissues
Being Tested |
Brachial
plexus (medial trunk, C8-T1) and the subclavian artery and vein |
Performing the Test |
The examiner
continuously palpates the radial pulse on the side being tested
while abducting the arm to 45 degrees, extending the shoulder to
45 degrees, externally rotating the humerus, and applying a
downward traction to the arm. The patient is then asked to fully
turn his/her head away from the side being tested and extend the
cervical spine. |
Positive Test |
Disappearance or decreasing of the radial pulse |
Interpretation |
Indicates
thoracic outlet syndrome. The presence of a cervical rib
compressing the neurovascular bundle may be responsible. |
Common errors in
performing exam |
Palpate the
radial pulse throughout the entire test, not just before and
after positioning the patient. |
Factors possibly
resulting in misinterpretation |
Radial pulse
disappearance is not by itself specific, but loss of pulse with
reproduction of symptoms is a positive sign for thoracic outlet
syndrome. |
