Distraction Test |
Examination type |
Neurological
test |
Patient & Body Segment Positioning |
Patient may
be sitting up straight on a chair with the neck relaxed or lying
supine with the neck supported and relaxed for the test to be
performed. |
Examiner Position |
During this
test the examiner will need to be standing and facing the
patients left or right side, whichever is more convenient for
the examiner. |
Performing the Test |
The examiner
will place one hand, with an open palm, under the patient’s
chin, while placing the other hand on the patient’s occiput.
Then, the examiner will carefully and gradually lift the
patients head (distraction) taking the weight of the head off of
the neck and shoulders. |
Tissues
Being Tested |
Neural
foramen and joint capsules around the facet joints of the
cervical spine. The neck extensor muscles are also secondarily
observed during this test. |
Positive Test |
If pain is
relieved as a result of the movement, then the test is positive
for nerve root compression and facet joint pressure. Determining
the grade of the pressure would be decided by the amount of
pressure and pain relieved while performing the test. |
Interpretation |
A positive
outcome of this test indicates that the patient has nerve root
compression and abnormal (increased) pressure on the joint
capsules around the facet joints of the cervical spine. |
Common errors in
performing exam |
Common
errors by the examiner would include improper position of the
examiner, and or improper position of the examiners hands.
Common errors by the patient include slumping (not sitting up
straight), and not relaxing the muscles of the neck and spine
which can result in an altered outcome of the test. |
Factors possibly
resulting in misinterpretation |
Other
problems of the spine such as other nerve roots, facets, or
muscles of the spine; technique of the examiner; position of the
examiner and patient; posture and muscle involvement |
Related tests |
Cervical
Compression Test-
equal to the cervical distraction test as it is testing for the
same tissues, but instead of relieving pain, the movement
reproduces pain
Spurling’s
Test-
superior to the distraction test in that it would be more
specific to the exact side or portion of the cervical spine that
is affected |
