Is there any regulation concerning what one's rights are if the Army
forces you to violate your permanent medical profile?  A profile is a
list of things you can or cannot do if you have a medical condition. 
The profile is created by a doctor employed by the Army.  The
situation is that my friend has a work-connected disability (a
permanent dislocated right shoulder, which has now required two
surgeries to fix and is still not in the best of shape), for which
they are putting her through a medical board to get her out of the
Army (and for which she will be on permanent disability through the
VA).  She has a permanent profile, which her unit is repeatedly making
her violate through lifting heavy objects, doing yard work, etc.  She
has suffered several re-injuries due to the activities they are having
her engage in that her profile says she should not engage in.  They
are also preventing her from going to some of her medical appointments
to deal with the shoulder.  She is currently not allowed to refuse
when they tell her to do things that violate her profile, because if
she does, she is disobeying a direct order (even though it violates
her profile) and will be subject to disciplinary action.  Are there
any Army rules or regulations (through the Inspector General or
otherwise) that allow her to have this situation redressed?  If so,
what are they, and how can she avail herself of them?  She is
stationed at Fort Stewart, GA.

Not to be a dick but your friend is simply not taking care of herself.
 I have been in that position as a member of the military and the only
way to fix this situation is for her to stand up for herself first
with her paperwork in hand.  If she fears reprisal then she should
document every instance of noncompliance.  Eventually in her chain of
command, provided she is not a slug, there will be a reasonable person
who will enforce the rule of medical limitations.  Have her speak to
the chaplain.  She CANNOT BE REFUSED.  If she is told she cannot speak
to him, she needs to get in writing that she is not allowed to go.  As
soon as she gets that written, not only will pigs fly, but she will
get the ball rolling in her favor.  The chaplains job is to take care
of their people and not talk to others about it.  He is an excellent
place to turn.  Best of luck.
