[Music] hey everybody Welcome to PT final exams chop and lift PNF patterns this is another crash course been making a couple of these lately about how to understand some principles that really trip up a lot of students and so today we're going to be talking about chop and lift PNF patterns and hopefully make things a little bit clearer as you're considering what these patterns really mean and how you can apply them in your practice as you head down head down the road so Technic let's talk first about the chop pattern I'm going to demonstrate that in the camera first you're not going to get a great picture of it there's a lot of other good YouTube videos that talk exactly about the chop pattern how to to do it but I want to talk about the mechanics and the principles behind the pattern which will help you understand and apply a little bit better so the chop pattern technically starts in a D1 flexion pattern on the reference arm right arm reference arm start with a fist and then you're coming down now the reason it's a chop pattern is because you're allowing your good arm or your non- reference arm to assist it as it comes down into a chop so as you start with a fist coming down you're opening your hand and coming to your side in D1 extension starting at the ear coming down that's what is called a chop pattern and the direction you're headed you know if again if we talked about the right arm is the reference arm the right arm is the reference arm has come across and is starting at your opposite ear and is moving down to your side in what is called the chop pattern now if you headed the opposite direction the opposite diagonal that would be technically a reverse chop so from one perspective you're starting with a reverse chop and going down into a chop reverse chop chop as you start from the chop you're coming back up into with a fist that is called a reverse chop again it's totally dependent on your reference arm if the right hand is reference arm starting in D1 flexion going to D1 extension is called the chop and coming from D1 extension with your your hand open all the way up to your ear is called D1 flexion or the reverse jop chop reverse chop so again that's the diagonal we're talking about now talking briefly about the lift lift is in the opposite pattern so again we were talking about the right starting at the ear and coming down now we're going to start with D2 extension which is remember this is grabbing the the sword out of your pocket or you know grabbing the sword out of the the sheath and coming up with your and opening your hand as you come past so you're coming from a fist coming all the way up and I'm showing it up a little higher so the camera will show it but in essence you're starting the opposite hip and then coming up into the D2 flexion pattern and the left arm is going along for the ride as you start with the Fist and come up D2 flexion and extension so as you come up that's what's called the lift as you come down that's what's called the reverse lift so again if we drew out the little guy if the right arm is the reference arm that we're talking about you're going to be starting up here well no I take that back you're starting down here at the opposite hip and working up this direction in What's called the lift pattern so the right arm is starting coming across like this the left arm holding on tight and coming up into D2 flexion so that's what's called lift and as you can imagine if you come back from the top of the lift down to the bottom again thus it would be called reverse lift now key distinction here is you have to understand which limb is the reference arm you know which arm is the reference arm because if you look at it starting up here and coming down that's what's called The Chop but if it was my left if I was looking at my left arm I'm starting in the reverse lift position or I'm starting lift position and coming down the reverse lift so chop or yeah coming from reverse chop down to chop is the same as going from lift to reverse lift again totally depends on which arm you're talking about so in this particular video we've been focusing on the right arm if the right arm starts up here in D1 flexion and comes down to D1 extension with the left arm along for the right that's what's called reverse Chop Chop reverse Chop Chop if we're starting from the opposite hip and coming up that's called lift with your hand open reverse lift coming back down lift reverse lift now again if I put my hands together just so there was no difference between the two and I started down here I'd be technically a chop on the left and a reverse lift on the right I'd come up into a lift on the left no a reverse Chop on the left and a lift on the right you can see how this gets really confusing really fast but again if you look at that diagonals if we're going up and down this way you know if those are the arrows here this would be the chop coming down and the reverse chop going back up again again this is all totally depends on the reference arm and then the as I've drawn up here that you have the lift and the reverse lift thus you have this diagonal pattern that can be very confusing if you forget which arm is the reference arm but always in the reference arm or the weak arm or the arm you're working on that's what you're going to title The Lift reverse lift reverse chop chop that sort of a thing so let's talk a little bit about application here so chop and reverse chop if you consider you know the biggest one that that we run into this with is stroke patients so if someone has a stroke you're going to want to work outside of synergy because usually their synergies are quite strong so you're going to try to work out of synergy so a chop the reverse chop chop with the right arm as you come down that's technically more inside of the Synergy than if you started with the reverse lift lift reverse lift lift again the idea is trying to get them out of synergy and if you can use their good arm to help their sore arm come out of synergy you're getting a little bit of active assisted range of motion that helps get them outside of the Synergy pattern and gets them more along the lines of functional you know more return to of function now if you had someone with just various type of shoulder injuries if you had a shoulder and it doesn't really matter which one basically you look for the impairment and you would allow the good arm to help the sore arm through the reverse Chop Chop or the reverse lift lift going through that again just basically it's active assisted range of motion trying to increase muscle strength and then the other one to consider is that with uh some type of spinal cord injury or other type of impairment where rolling is where you can't roll or functionally roll very well in supine basically the the chop is going to be your best friend as you come from a reverse chop to a chop you're going to rotate as you go into you know into the full chop pattern so you get the rolling function there you go so a quick crash course again just meant to be a few quick thoughts on how to distinguish the difference between a reverse chop and a chop and a reverse or yeah reverse lift and a lift based on the reference arm and that the other arm is doing the opposite thing as it goes through the patterns but that doesn't really matter as much if you understand what your reference is so thanks again appreciate it PT final exam your awesome resource preparing for the npte check out my other videos on YouTube
