Spurling's Test |
Examination type |
Neurological
|
Patient & Body Segment Positioning |
The patient
can be short sitting on an examination table, lying supine on an
examination table, or seated in a chair. |
Examiner Position |
If the patient is short sitting on an examination table, the
examiner should kneel on the table 8 to 10 inches behind the
patient. If the patient is seated in a chair, the examiner
should be standing beside or behind with the arms slightly
flexed and both hands resting on top of the patient’s head. The
elbows should be roughly eye level to the patient. If the
patient is supine, then the examiner should be seated with the
patient’s head 6 to 8 inches in front of the examiner’s chest.
The examiner should support the head and neck completely with
one hand and the other should be placed on top of the head. |
Performing the Test |
Begin by performing the basic cervical compression test for the
neck. First tell the athlete that you are going to be placing
increasing pressure on their head, and ask them to inform you
when it begins to hurt and what type of pain and sensations are
felt. The patient should be looking directly ahead with the head
in neutral (no flexion, extension, or rotation). If pain results
or a numb, tingling, or other noticeable sensation radiates down
the arm, stop the test immediately as this is a positive sign
for nerve root compression. If no pain is felt with the basic
cervical compression test then the examiner can progress to the
Spurling’s Compression Test. First place the neck into extension
and compress the head downward along the long axis. Next,
rotate the head to either side while still extended and apply
compression. Finally, place the head in extension, rotation, and
lateral flexion then press downward again. After placing the
neck into the each position, place the hands on top of the head
again and begin to compress straight down, with slightly
increasing pressure. |
Tissues
Being Tested |
cervical nerve roots |
Positive Test |
Pain felt in the arm on the same side that the head is flexed
during compression. As soon as pain is felt the test should be
stopped; the test should not be continued long enough to “rate”
the pain. Severity of the compression of the nerve root is best
measured by location of the pain. For example, is it just pain
in the neck, or pain in the neck and shoulder, or pain in the
neck, shoulder, and arm with radiating abnormal sensation.
|
Interpretation |
A positive test indicates that one or more of the nerve roots
coming from the cervical spine is being compressed by a
fractured or displaced vertebrae, swelling, scar tissue,
prolapsed or herniated vertebral disk, or by severe muscle
spasm. Spurling’s
tests for
nerve root involvement in a cervical spine injury. |
Common errors in
performing exam |
Remember: Passive tests are more dangerous than active tests
when used on the spine due to a risk of an unstable vertebral
column. Use extreme caution when performing this test. Pay close
attention to what you are doing and keep the athlete’s safety in
mind. Do not be afraid to cause a little discomfort of the
athlete to find out what is ultimately causing their pain, but
never cause further harm. |
Factors possibly
resulting in misinterpretation |
Muscle or ligamentous injuries to the same area can cause
misinterpretation. The Reverse Spurling’s test will aid in the
correction of this common mistake. An increase in pain with
this test indicates the injury may be a muscle injury caused by
stretching the injured muscle. A decrease or alleviation of the
pain with this test indicates a releasing of the pressure on a
compressed nerve root. |
