Interpretation |
Distinguishing
what is hurting as the examiner does this test is very Important
and also knowing which tissues being stressed. In this case
it could be a S-I joint problem but, which one? Thats why the
test needs to performed bilaterally and ask the patient "tell me
where does it hurt" "Does hurt down in the S-I joint or does it
feel like a stress on the ligaments." Or does it hurt in the
lower back which could indicate a lumbar problem. These ideas
should be in the examiners head in fining the interpretation of
this test. |
Common errors in
performing exam |
Common
errors in performing this test would be wrong hand
placement and not stressing the joint enough to get the results
that are desired. |
Factors possibly
resulting in misinterpretation |
The factors include not asking
specifically where pain is so that is is unclear of the actual
problem. A tight rectus femoris might keep the ilium from
moving the motion that it should. |
