Park et al. Subacromial Impingement Testing Cluster

This is Brent of the Brookbush Institute, in this video I'm excited to bring you these special tests. I actually use them here in clinic which is with these testing clusters. In this particular video we're going to go over the Park et al. impingement testing cluster. I'm going to have my friend Melissa come out, she's going to help me demonstrate. Now we're going to assume that I've already done a subjective examination and that Melissa's complaining about some chronic shoulder pain, not necessarily acute shoulder pain but something that's been coming on for a little while. She's feeling it maybe during her workouts. We're going to do the Hawkins-Kennedy, the infraspinatus and the painful arc tests. So that is your Park et al. cluster: Hawkins-Kennedy, infraspinatus, painful arc. I'm going to go ahead and grab her by the elbow right with that lumbrical grip, stabilize her scapula so I don't get upward rotation, then lay my palm down so I have good control of her torso, take her to 90 degrees of horizontal adduction and flexion, give her a little internal rotation. How does that feel? That doesn't feel great that gives her a little pain, is that the symptoms you were talking about? Okay so that is her concordant sign. Let's go ahead and do the infraspinatus test. I'm going to grab and stabilize her elbow, on this one I would demonstrate first, so what we're going to do is we're going to turn out this way. I don't want this thing right, I don't want you to push out against my hand, I want you to like turn out against my hand, I'm just gonna use this hand to stabilize. All right so I'm going to hold her at the elbow, apply some resistance here at the wrist, go ahead and turn out. How does that feel? Feels fine, that feels fine, and she actually feels pretty strong. She's kind of jacked, buff, (I am), huge. No girls don't want to be huge right. All right go ahead and stand up, we're going to do the painful arc test. All right remember on this one that client patient communication is real important, so I want you to tell me when that pain starts, when it's at its worst, and when it goes away, as you slowly take your arm all the way up, okay but sideways. Go ahead and go up, okay no pain, no pain, okay go ahead and sit down. So we had a positive Hawkins-Kennedy, but a negative infraspinatus, and a negative painful arc. Chances are this is not impingement syndrome. All right so now we're going to have Melissa act this out for us in a little different scenario, we're going to see what her acting skills are. We're going to do the same test but this time we're going to pretend that you've had a fair amount of pain, you don't remember a specific instance, it's been getting worse and worse during your workouts. At this point you can't really do upper body workouts. Nice picture, all right good. So once again we're going to do the Hawkins-Kennedy, go ahead and keep that scapula stabilized, torso stabilized, internal rotation. Pain, and that's the symptoms you were talking about. Okay so we got that concordance sign. All right again I'm going to brace the elbow, brace her wrist, she's going to push out. All right, hard, doesn't feel good and I actually notice this time that she has some weakness, she's able to push against me but she's not able to sustain it, she kind of falls apart a little bit. Go ahead and stand up, let's see that painful arc. All right remember tell me when it starts, (starts right here), okay where is it worse, (here's at its worst). Okay what about there, okay and then at the top it's gone so that would be a positive painful arc sign. Good go ahead and sit down. So if I have those three tests, i have positives on those three tests we have a pretty good idea that she is positive for impingement. Now the Hawkins-Kennedy is probably the strongest test of those three, but combined the Park et al. cluster is a much stronger diagnostic tool. The only problem we have with impingement syndrome is as a diagnosis it's not very helpful to us as far as prognosis, or predicting interventions, or deciding what our intervention should be. So we're still going to have to follow this testing cluster up with maybe some other testing clusters to rule out stuff like labral tears, or perhaps stuff like rotator cuff tears. We're also going to need to follow up with a movement assessment, maybe the overhead squat assessment, and some gloniometry so that we have a better idea of what interventions could help her improve the quality of our movement, and improve her symptoms. So there you guys have it the Park et al. testing cluster that's going to be Hawkins-Kennedy, infraspinatus or resisted external rotation test, and the painful arc test. Good diagnostic tool for impingement, but we have to keep in the back of our head that impingement as a diagnosis is not particularly helpful.
