- Ready.
- Okay.
- Hi, I'm Bob Schrupp, physical therapist.
- Brad Heineck, physical therapist.
- And together we are the most famous physical therapists
on the internet.
- Well in our opinion of course, Bob.
- Brad, and then going along
with trying to help determine what your shoulder
pain may be coming from, today,
we're gonna talk about whether
or not your pain may be coming
from your AC joint.
- AC?
- Not air conditioning.
- AC, DC.
(Brad laughs)
- I know that's what you're thinking,
but actually it's acromioclavicular.
- Okay.
- And just very quickly, we'll show you where
this joint is.
If you look along the collarbone,
Brad, do you wanna go ahead and show where it is?
- Yep. Right here, we got the collarbone both sides.
I'm gonna go on this side, cause it's closer to me.
And if you follow with yourself along that collar bone
where Bob is going right there,
it gets a little harder over here
because you get some tendons and soft, soft tissue in there,
but it connects up to the acromion,
which is this paddle-like bone here,
which is part of your shoulder blade.
And there's a joint right there,
and you can feel it in there,
and that can be tender sometimes right on that joint.
- Right. And you can actually dislocate that.
- I did. I dislocated mine playing volleyball.
- Sure,
and you can do it by landing right on the shoulder.
- Yep.
- It often hurts to lay on that shoulder
when you're sleeping at night.
Although, there's a lot
of things that'll hurt when you're laying on it.
- Right.
- Overhead activities can hurt.
And it, it also the, where I tend to actually get it injured
or bothered is if I do a lot of bench press or pushups.
- Yeah.
- That's when it starts to hurt on me.
So we're gonna show you three tests you can do on yourself.
Real simple ones.
- Oh, just to clarify, I hurt my playing volleyball
but not playing the game.
I fell down and landed on my shoulder, so.
- I don't even want to know.
I don't even know.
Okay. The first one, we've heard this thing
called different things.
One place called it the scarf test.
So, I'm testing the right side, Brad.
- Um hm.
- So you just take your hand and grab your left shoulder
- Um hm.
- and then you can just actually take the other hand
and push the elbow up like this.
- So straight up or up and over?
- Yeah. Straight up.
- Okay.
- Now if you're gonna test the other side,
you just reverse it.
- Right.
- And go up like this.
Now again, interestingly enough, I'm having a little pain
on this side and I do this and this is
I feel it on this side and I don't feel it on this side, so.
- Positive test orders.
- Positive test on here.
Positive meaning that it's
it did give some reaction.
- Right.
- So.
- What's the next one?
- The next one.
What is the next one?
The pull apart test.
(they laugh)
Sorry about that.
Okay. The pull apart test.
Very simple.
You're gonna grab your hands like this,
your fingers together and pull apart.
- Right.
- So if I wasn't, you know, if I,
if they weren't holding, I'd actually go like this.
- Right.
- Same thing with this one.
I can actually feel that one Brad in there.
- Sure.
- I can, I can feel it on this side.
I don't feel it on this side.
- So you got two positive tests.
- I got two positive tests.
The third one is a very simple, well
horizontal abduction, adduction, I'm sorry.
Bring your arm over and across
like this or like this.
- Right.
- Now on this one, I really don't feel it.
- Right.
- And this one could also be an impingement
I think would, could give you trouble with this.
Don't you think?
- Right. You could get that hurt.
That, that's crossover test for that too.
- Yeah. So anyway, three tests,
two out of three are positive on me,
which, eh, a good sign that I do think I have a little
AC involvement. I, and I do.
So I, I think these are three tests you can try.
Again, in the future, we'll have a video
on what to do about this.
- Sure.
- There's some treatment that you can try.
- Right. Right. So again,
these tests are, if you have three out of three positive,
you probably have an AC,
but it doesn't necessarily mean your AC joint is,
you know, injured.
- A physical therapist is gonna do some other tests too
probably to determine whether or not is the issue.
- Yeah.
- But again, kind of give you a ballpark idea whether
or not you're you're, you know, what might be bothering you.
- Right. So you're not wandering
out in the dark thinking, what is it?
