You are now tuning in to the MPTE clinical files to mock MPTE-based questions told and solved

week by week. Thank you for tuning in to the MPT clinical files. My name is Kyle Rice, the MPT

prep coach, the founder of the PT Hustle and the creator of the MPT Prep Success Coaching Program.

And if you would like a free cheat sheet that goes along with this specific

question tune in to the end of this episode and I'm going to give you more information on how to

get that all right so for our next mpt clinical file we have our patient Noah and Noah is being

educated on the pressure relief strategies to use with his new manual wheelchair.

With elbows placed on the armrest, the patient is unable to perform a standard lift of the buttocks.

Which of the following muscle groups should be assessed for strain?

So we have A, upper trapezius and rectus

abdominis, B is latissus dorsi and lower traps. C is triceps and serratus anterior. And D is

Terry's major and posterior deltoid. All right. So I was just telling everybody about this how

I don't believe I was ever taught in PT school about reverse muscle actions. And that's exactly

what this question's pretty much referring to. And if you don't know what reverse muscle actions are,

hold on a minute. Let me talk to you about that first before we jump into this one. So you know how typically when we're looking at a muscle action, when we learn it, we oftentimes learn it in like an open chain format, meaning that the insertion moves towards the origin. Is that kind of confusing? All right, let me specify a little bit.

Think about a bicep curl, right? You got a little dumbbell in your hand, you know,

five pound, ten pound, don't hurt yourself. And you're doing a bicep curl. What's moving towards what? Wouldn't you say it's the insertion of the biceps that's moving closer to the origin?

If we were talking about the long head of the bicep, we would say that the radial tuberosity where it's inserting into is moving closer

to the superglinoid tubercle where it originates. See, insertion moves closer to the origin.

That's elbow flexion, right? Okay, cool. Well, reverse muscle actions, a lot of times occur

in more of like a closed chain type of movement where the muscle actions can oftentimes, you know, for different muscles, flip, do a reverse action. And we're getting asked this type of stuff on our practice exams and we have no idea. Why? Because we've never really looked at it that way.

And so I made this question right here for us to go through to kind of simulate what I'm talking about.
