I am a workers compensation attorney asking about the specific test
used for evaluation of an upper extremity disability following surgery
for a rotator cuff repair, specifically under the catagory:

FLEXIBILITY/POSITIONAL  Elevated Work

What is the specific test administered and what is it intended to measure?

The test result is that my client is "unable to maintain elevated work
with bilateral upper extremities for greater than 2 minutes".
The insurance company is attempting to portray this as working with
hands over her head?  Is this correct?   I read it as any work that
required the hands to be elevated, such as holding hands up to do
assembly work.
Reference materials?

Any physical capacity evaluators out there?

If I have the time later and no one has answered your question, I will
certainly have a look. I will attest, however, that as an avid swimmer
who underwent rotator cuff surgery, I was reduced to "baby moves" for
quite a while until my arm regained strength and motion! I would not
have been able to perform many overhead moves with confidence,
especially if they involved any sort of weight-bearing requirements.

In this case, elevation means abduction of the arms, which means
drawing them away from the midline of the body.
