I feel everyone knows that the time period “shoulder impingement” may be very nonspecific. It could imply a number of issues.
Many have argued that the time period “impingement” tends to suggest a biomechanical pathology. That isn’t all the time the case, however typically it’s.
However it doesn’t must be complicated. Right here’s how we outline “shoulder impingement,” give it some thought throughout our evaluations, after which use the information to construct a therapy plan.

Pupil:
All proper, we bought Jackson from South Carolina. As a PT pupil, I’m at the moment discovering it troublesome to strategy the broad phenomenon of shoulder impingement. How do you guys go about assessing this situation, and what are the most typical findings you see in a affected person or athlete?
Mike Reinold:
Superior. Good job, Katie. All proper. So Jackson says as a PT pupil, so I get this one, that is fairly good shoulder impingement’s gigantic, proper? And I feel that’s an enormous level. And what he says is how do you go about getting it began? He’s discovering it troublesome to even simply begin with shoulder impingement.
Mike Reinold:
And I feel that is sensible. I feel we have now a number of diagnoses which have these such broad phrases that typically it’s not useful. Why don’t we begin with this? Why don’t I throw this at you guys, and we’ll see what we get for some solutions. However why don’t we begin with this? What’s shoulder impingement to you guys? And that is like a type of private questions, as a result of I feel the reply just isn’t black and white.
Mike Reinold:
However in case you have anyone that you’d say has shoulder impingement, how would you even outline that? And we might have a complete separate matter if shoulder impingement is even the proper time period to make use of, and if we’re even nonetheless utilizing that. However why don’t we speak about definition first earlier than we speak about treating slightly bit, as a result of perhaps that may lead into that.
Mike Reinold:
So who desires to begin with that? I’ll form of throw that on the market. How do you outline it, and do you assume shoulder impingement is the proper alternative of terminology for anyone with this? Dan Pope, what do you assume buddy? [crosstalk 00:00:03:20].
Dan Pope:
I feel this can be a good alternative to sound silly, get thrown underneath the bus slightly bit. Yeah, so I suppose shoulder impingement is slightly deceptive simply because we predict that the rotator cuff can get irritated by way of some compressive mechanisms, that might be coming from the acromion, that might be coming from the glenoid, so we don’t actually know the place that’s coming from, and it’s totally different based mostly on the particular person. And the compressive points might be resulting in pathology, or it might be perhaps a few of the tensile load the athlete’s going by means of. So whenever you say shoulder impingement, a minimum of to me, it sounds such as you assume these compressive forces are the primary drawback, and also you’re attempting to handle these particularly. Though they most likely stay along with different forms of forces that, let’s say the tendons aren’t dealing with effectively, after which you find yourself with ache.
Mike Reinold:
So do you assume Dan, you assume it’s not all the time compressive forces. As a result of shoulder impingement is kind of a biomechanical time period. Impingement means like should you’re taking the ball and socket joint, and you’ve got your rotator cuff, and your subacromial area, you’re impinging the rotator cuff, most likely between the humeral head and the acromion, perhaps the coracoid, perhaps the coracoacromial ligament, no matter. However it’s implying impingement is the pathology. So are you saying compression may not be it? What else might or not it’s Dan?
Dan Pope:
Yeah, I went down a reasonably large rabbit gap at one level attempting to determine these items out. As a result of the research are far and wide. So you have got some research which can be carried out in cadavers, you have got some research are carried out with MRI, you have got some research which can be underneath arthroscope and surgical interventions, and so they’re attempting to see if impingement is incurring, and it modifications from individual to individual. So a Neer’s take a look at, for instance, might present no impingement in any respect in a single particular person, and it’ll present a ton of impingement and the following particular person. In order that’s really fairly difficult, I feel, to determine should you’re getting impingement as a major pathology. And I wish to apologize, I misplaced my practice of thought. What was your unique query?
Mike Reinold:
So I suppose the query is that if it’s not all the time compressive, what else might or not it’s?
Dan Pope:
Okay. So I feel oftentimes your rotator cuff is simply working lots whenever you’re doing workouts. For my inhabitants they’re within the fitness center, so should you’re doing a bench press, your rotator cuff is working lots. And folks are inclined to overdo urgent workouts, that are usually working the infra and the supera bit extra. They usually find yourself with ache particularly with urgent, often.
Dan Pope:
I feel oftentimes that’s an overuse situation. So that you’re utilizing that tendon a ton, and should you overuse a tendon, let’s say a patellar tendon, or Achilles tendon, it turns into painful, and you may develop tendinopathy simply since you’re utilizing it a lot. So I feel that that’s most likely one of many issues occurring.
Dan Pope:
In the event that they’re getting some elevated compressive forces, let’s say somebody’s snatching and their finish vary, and so they’re getting extra compressive forces, they might find yourself with ache merely due to the place, and so they’re getting that compression. Whereas somebody who’s simply doing a ton of bench press may not be getting these compressive forces, however they find yourself with the same kind of ache, and simply irritation, however of the identical tissue, I suppose.
Mike Reinold:
Proper. After which should you take a look at your medical examination, and also you take a look at your particular assessments, the particular assessments are compressing, they’re compressive-based assessments.
Mike Reinold:
However I like your level the place typically it’s emulating the mechanism of damage, which may be compression, however typically you’re simply compressing an irritable tendon that’s already irritable for another causes. So sure, compression might annoy it, however that doesn’t imply that’s what precipitated it. So I like that, I feel that’s level.
Mike Reinold:
Let me ask one other query to the group on impingement on this, so is compression and is impingement regular? And once I increase my arm up within the air proper now, am I impinging usually? And does anyone know what the analysis reveals on that slightly bit?
Lenny Macrina:
I feel so, I feel so. I feel the analysis does say that it does occur. I don’t know why precisely the tendon finally breaks down. Since you’re going to see the tendon is breaking down in areas the place it does form of impinge on the acromion. You recognize what I imply? And it’s additionally a watershed zone, so there’s not blood provide to the world. In order we age, perhaps it may’t deal with the forces which can be being put by means of it as a result of it’s nonetheless compressing.
Lenny Macrina:
So the time period impingement, I do know social media desires to throw it out as a result of it’s a scary time period for folks. However should you clarify it accurately, it doesn’t should be scary folks. Like to return on, there’s a pinching-type phenomenon that’s most likely occurring over time that’s the reason, together with an overuse factor. So it’s a combo of the 2. So to simply throw the time period out, positive, we will name it, “Non-specific rotator cuff pathology.” Whoa, now we have now pathology in our rotator cuff.
Mike Reinold:
What if it’s not the rotator cuff too? What if it’s-
Dave Tilley:
Proper, it might be reversal, within the biceps, it might be so many various issues. So proper now I feel the flowery time period is non-specific rotator cuff pathology, similar to non-specific low again ache is form of the time period. And once more, we’re simply enjoying phrase vomit proper now with a few of our phrases, with a few of our pathologies to not be so scary, but-
Mike Reinold:
I used to be in a web based dialogue about this too, but when we’re going to alter terminology, it has to simplify and make clear. Proper?
Dave Tilley:
Proper.
Mike Reinold:
And I don’t assume we achieved both of these with that one proper there.
Dave Tilley:
No it undoubtedly makes it extra imprecise, extra common, and now it’s as much as us once more, to elucidate it. So it nonetheless comes again to us to elucidate it accurately. Now, I fully, some individuals are going to elucidate it incorrectly and create this loopy situation in anyone’s shoulder, the place it’s simply going to create extra ache, and we all know all that undoubtedly contributes to anyone’s ache, is being anxious about their damage.
Dave Tilley:
However I feel the conventional therapist, the conventional person who’s coming in for PT is doing job serving to folks with speaking to them, and speaking them by means of the pathology, and social media goes to drag out that 10% of the loopy tales which can be on the market and simply true escalate it.
Mike Reinold:
Proper. Proper. Dan, what have been you considering there? Did you have got some followup on that?
Dan Pope:
Yeah, I’m sorry, I don’t wish to hijack. I simply did like a-
Mike Reinold:
Hijack man.
Dave Tilley:
[inaudible 00:09:37].
Dan Pope:
… actually deep dive into impingement as a result of I’m attempting to know it. However yeah, it’s regular, and customarily talking, you’re getting impingement in what we take into account the painful arc of movement. So whenever you increase your arms overhead, whenever you get round 90, there’s extra impingement. A variety of the analysis I learn is that the zone or the painful arc is far decrease than we are inclined to assume.
Dan Pope:
So, historically, I suppose it’s someplace between let’s say 80 and 110, or perhaps slightly bit larger or decrease than that, it’s most likely a bit decrease than that, and it’s regular to get impingement; everybody’s going to have that. There’s extra compressive power on that tendon. And that was the reply that I used to be attempting to…
Mike Reinold:
And I admire that. I feel within the regular arthrokinematics of the shoulder, it’s not like you have got empty area in your physique, and it’s simply bought all this room for the humeral head to maneuver up and down, there’s not a number of empty area. So yeah, whenever you transfer, sure you impinge. However that is the place I feel we run into some troubles with, particularly a few of the youthful clinicians and college students right here, is the place they assume like, “Properly, if each time I elevate my arm, I impinge, then that’s not unhealthy, and we have now to watch out saying that’s unhealthy.”
Mike Reinold:
Properly, let me throw this at you guys as a gaggle. What if I’ve a good inferior capsule? What if I’ve poor rotator cuff stability? What if I’ve extreme laxity in my joint and I can’t stabilize, and I get superior and humeral head migration?
Mike Reinold:
What if that standard compression, let’s make issues up, please don’t annoy me on social media by responding to this. Let’s say each time I elevate my arm, there’s 10 kilos of stress on my rotator cuff, however my inferior capsule will get tightened, and now it’s 15 kilos of stress. Please don’t touch upon that. But when that occurs, is that good? Is that unhealthy? Are we constructing extra resilience of the tissue? I don’t know, I feel that is the place we have now to watch out saying that impingement’s regular as a result of there’s different methods that may improve the compressive forces.
Dan Pope:
I don’t know. I’ll let [inaudible 00:11:34] discuss.
Mike Reinold:
Dan’s going to get labored up. What do you assume Tilley?
Lenny Macrina:
I’m studying to [crosstalk 00:11:37].
Lenny Macrina:
I feel to return to the unique query, this particular person, I feel it was a pupil wished to know what we’re searching for. We’re searching for is ache making sense with the damage and their perform?
Lenny Macrina:
First, I wish to ensure, like in head, I’m considering, “Is it a neck factor? One way or the other is the ache, is there something happening beneath the shoulder? Is it happening form of beneath the deltoid insertion, happening to the elbow and the hand?” That’s an enormous pink flag for neck points.
Lenny Macrina:
Is it not like a thoracic allotype factor? Is it not a biceps situation? Or some form of different tendonous situation? However all that stuff within the shoulder doesn’t matter, you’ll be able to form of handled the identical manner, proper? Restore their mobility and work on their strengths. So I feel we get so caught up with the prognosis that we are inclined to deal with it the identical manner anyway.
Lenny Macrina:
It’s going to be exercise modification, slowly ramping up their quantity, restoring their movement, if they’ve an absence of movement, such as you mentioned, an inferior capsule situation. So how can we do this? Self vary of movement, delicate fascia launch, all these issues, joint mobes, after which giving them program for his or her rotator cuff.
Lenny Macrina:
And I feel it’s that straightforward. We don’t should get too slowed down with loopy terminology. However individuals are going to PT as a result of they wish to know why they damage. In order a lot as we don’t should put a prognosis on it, folks wish to diagnose; I am going to the physician, I don’t wish to depart with a prognosis of knee ache once I know I’ve knee ache, I simply spent a ton of cash to be advised I’ve knee ache, however that’s what occurs.
Lenny Macrina:
So as much as us to attempt to do our greatest to get as tissue-specific as potential figuring out, and that’s what I clarify to my folks, “It will not be, however it appears to be that manner, and that is what we will do that can assist you.”
Mike Reinold:
What should you noticed the physician and he mentioned you had nonspecific knee ache, would that assist?
Lenny Macrina:
Precisely.
Mike Reinold:
Would that assist, or irritate you extra? You’re similar to, “Properly, no, it particularly hurts on my knee. I don’t what you’re…”
Lenny Macrina:
It could create extra anxiousness for me, my ache would go up, proper?
Mike Reinold:
Piggybacking off of what Lenny mentioned, I’d say for me, I’ve not mentioned, typically I’ll say I’ll use the phrase shoulder impingement, however I’ll simply inform folks proper now it’s like, “Look, right here’s what we all know, your shoulder is irritable proper now, the tissue in your shoulder is irritable.” And I say that fairly a bit, and it’s arduous to disclaim that, proper?
Mike Reinold:
So, “It’s irritable. I confirmed you on a few these assessments that I can do a few maneuvers that provoke it. So it’s irritable. We nonetheless want to determine why. Is it simply workload? Is it your capability of your physique wasn’t prepared for it? Do you have got some sub optimum issues in your physique that perhaps improve the stress like we talked about beforehand?” All these types of issues form of put collectively, however I agree, I simply form of say like, “Look, you have got an irritable shoulder. I feel that’s all that issues.” And also you nearly all the time blame it on workload, or your physique’s capacity to deal with the workload greater than to say, like, “Your drawback is your bone or your acromion. Your drawback is your workload and stuff like that.” So, Mike, what do you bought?
Mike Scaduto:
I used to be simply going to say because the youngest clinician within the crew, form of serving to a PT pupil, I feel an enormous a part of that is having a standardized evaluation for the shoulder that you simply use in a really particular order. I feel typically should you go and do a provocative particular take a look at early within the examination, it turns into slightly bit extra murky. So perhaps saving these provocative Neer’s Hawkins–Kennedy impingement take a look at in direction of the top of the examination, to form of see if that’s provocative and never attempting to impress ache, after which take a look at different issues the place it turns into slightly extra murky, I feel that’s the place some PT college students get in bother with a shoulder examination.
Mike Reinold:
Proper. I like that. Dave, what’s up? What do you assume Dave?
Dave Tilley:
Mike mentioned what I used to be form of considering already, is I feel within the context of your order, your particular assessments and stuff like that, but in addition I feel a number of occasions college students, there’s a lot literature on there on what might be contributing to why the world is delicate or overloaded. Thoracic spines, scapular mechanics, capsular stuff, delicate tissue, power, workloads. I feel college students sadly typically simply form of get overwhelmed, and so they simply begin greedy at straws for random issues they assume might be a part of the issue.
Dave Tilley:
And so one thing I’ve been attempting to work with a number of the scholars at Champion is like have three aggressive prognosis in your head, like labural, AC joint, and perhaps one thing within the cuff. And the way are you going to show to your self with a scientific examination which a type of is essentially the most possible to begin with?
Dave Tilley:
So clearly have your native shoulder examination, however then I am going, “Okay, I bought to examine T backbone mobility, I bought to examine the neck,” like Lenny mentioned, “I bought to examine some power.” You bought to be sure to have a really standardized, like Mike mentioned, reproducible the entire time, so that you’re not simply swimming in particular assessments and random issues to do.
Mike Reinold:
Yeah, I prefer it. After which I’m going to make your life lots simpler Jackson, is I’m going to say form of what Lenny mentioned already right here, however a part of with me saying, “Hey, your shoulder is irritable,” signifies that the true particular prognosis, if we’ve dominated out issues which can be problematic, labral tear, rotator cuff tear, the massive issues, if we dominated that out, and we now have, what was it, non-specific rotator cuff pathosis [crosstalk 00:16:24].
Lenny Macrina:
[crosstalk 00:16:29] pathology.
Mike Reinold:
Neural biomechemical. It has been some time since we pulled neural biomechemical out. When you’ve got that, the rationale why I’m comfy with that prognosis is as a result of at that time limit, I’ve already made the choice on what my therapy strategy goes to be, and dialing it down if it’s superspinatus, his biceps tendon, or his bursa, or no matter it might be, doesn’t change my therapy paradigm at that time. So I form of simply form of transfer on.
Mike Reinold:
Now I hate to say it, Dave and Lenny form of mentioned a few issues they’d begin doing for therapies. It’s about getting the cuff sturdy, in order that manner you’ll be able to heart the humeral head. Dave talked about thoracic mobility and stuff like that. What are we doing? We’re reducing the possibilities of compression, proper? I hate to say it like, let’s simply name a spade a spade typically. However once more, what we’re attempting to do is take a few of the compressive forces off the cuff.
Mike Reinold:
So once more, are there occasions the place anyone has a whole simply tendinopathy-type state of affairs that’s not from compressive forces? After all. However I feel all of us supraspinatus, let’s recover from that, however there’s issues that we will do this both improve the impingement or improve your physique’s capacity to deal with the stresses that come from that impingement.
Mike Reinold:
And also you form of put that collectively. Like now you add that with some tensile stress, like Dan mentioned, then now you’re form of getting some double whammies, and that may be why we have now some youthful technology folks with rotator cuff tendinopathy, is as a result of they’ve the conventional compressive stresses with tensile stresses from a few of their aggressive issues that they’re doing. And you place these two collectively, and perhaps that’s like that complete analogy of the weed, proper? Pulling the weed out of the bottom, you don’t pull it straight up out of the bottom, you form of go aspect to aspect to drag that weed up. Perhaps we’re getting compression, pressure, compression pressure, that type of factor.
Mike Reinold:
So anyway, so good query, Jackson. I feel we didn’t discuss a ton about therapy. And I feel that was intentional as a result of I really thought out of your query that the steering you really wanted was to take a step again and assume it’s not that you simply’re essentially lacking something in your examination, this can be a massive matter, however it might not essentially change your therapy strategy. So hold so form of hold that in thoughts.
Mike Reinold:
So, nice query, nice solutions from all people. I admire this dialogue. I believed this was episode. So thanks a lot.
