OMM question for my test

[okayplayer]

I have my final on Monday and I am just wondering what the results of seated vs. standing flexion tests actually tell me? Not really sure, didn't see it in my notes either.

As you can tell, I am an OMM prodigy.

Thanks guys

+ test = the PSIS came up (cephalad) as the person flexed from the waist....dysfunction is on the side that came up

+ standing, - seated = innominate dysfunction
- standing, + seated = sacral dysfunction
+ standing, + seated = sacral dysfunction

don't forget about the situations giving false positives and negatives...

Thank you much

Sitting is sacroiliac and Standing is iliosacral.

we were required to specifiy the difference.

You must have had one hell of a lab instructor...damn. 😉


Think of it this way...

A STANDING flexion test takes into account the ilia.
A SEATED flexion test CANCELS out the ilia...the patient is sitting on them therefore they are nullified...at least for the purpose of this physical exam technique.

An innominate dysf will give you a + standing flexion test
A sacral dysf will give you a + seated flexion test and often a + standing flex test

I am new with that. What is false positive and negative?
I understand that if you get positive sign it can be faulty for that what you are looking for but positive sign for some other problem to exist. There is no faulty postive. Abnormal behaviour is a sign and something is causing it. It can't be faulty.
But what is false negative? You know some sign must appear but it doesn't? Why is that faulty? Are you sure that is not a sign for something else?

a false positive is when you get a positive result when there really is not a positive result

a false negative is when you get a negative result when the result is really positive

each test has a certain specificity and sensitivity which tells you the probability is of getting a false positive or a false negative.

...I think

a false negative is when you get a negative result when the result is really positive

That is a matter of opinion. If seated flexion test is positive what could cause false positive sign?

each test has a certain specificity and sensitivity which tells you the probability is of getting a false positive or a false negative.

That also depends who you ask. Others don't even use flexion tests but they use provocation tests only. So they are looking for pain, not dysfunction. Pain can be on the other side than the dysfunction, and many times it is.

...I think

Many only think. But is there any who knows?

ok. is there something I don't know about this thread? Twice it's gotten resurrected from the dead on about the 10 month mark.
