Pelvic Rocking Test |
Examination type |
Joint stability |
Patient & Body Segment Positioning |
The patient will lie supine on the examination
table. The hips of the patient need to be exposed. The shirt
will be rolled up just a little and the pants will be rolled
down a little. The patient’s iliac crests need to be exposed.

Examiner Position |
The examiner is standing over the patient. The
examiner’s hands will be on the iliac crests with his thumbs on
the anterior superior iliac spines. The palms of the examiner
will be on the iliac tubercles |
Tissues
Being Tested |
The pelvis is being stressed. The iliac crest is
being pushed in on. Both ASIS’s are being stressed. This is
testing the sacroiliac joint. |
Performing the Test |
With the hands in the correct position. With
palms on both ASIS. You will then push/compress them towards
each other. The will be pushed towards the midline of the body.
|
Positive Test |
With a positive test there will be pain
around the sacroiliac joint. A positive test may also be
positive if there is increased or decreased motion on the
injured side. |
Interpretation |
When there is pain on the sacroiliac joint this
indicates a problem. This may mean there is a trauma to the
sacroiliac joint. There may also be an infection to the
sacroiliac joint. |
Common errors in
performing exam |
When performing the rocking test common errors
may be easily performed. The incorrect hand placement is the
most common error people make when performing this test. When
doing this test it is also important to use the correct amount
of pressure. People will often not put enough pressure on the
ASIS. Examiners must also make sure they push toward the inline
of the body and not directly down. |
Factors possibly
resulting in misinterpretation |
A misinterpretation may be found when the
examiner pushed to hard and the patient complains of pain. The
pain may be caused by the pushing and not the sacroiliac joint
problems. |
