Welcome to Pilates Elephants, I'm Raphael Bender.
::Are contraindications obsolete? Well, in Pilates specifically and exercise more
::broadly, I'm going to argue that most of the ones that you're probably taught
::and that they're commonly agreed to be contraindications are not.
::There are a few situations where there are genuine contraindications to specific
::conditions and I want to go through a couple of those examples.
::I'm going to talk about what a contraindication is and what it's not,
::and how to differentiate. And I want to talk through the reasoning.
::And I think there's a misunderstanding here that is super common in the Pilates
::and fitness worlds about the nature of injury and pain and physical rehab.
::And this whole episode was prompted by a really thoughtful comment.
::I'm not going to mention the name of the person who commented,
::even though it was very respectfully put and whatever.
::But basically, this is a comment to a post I did on Instagram recently about
::this topic saying, you know, within the ACSM guidelines, here are some things
::that are not contraindicated that people commonly think are.
::One of the things I quoted was, you know, flexion is not contraindicated for people with disc bulge.
::And I'm just going to read out the comment here.
::Ever tried to do side sit-ups on the reformer box or swan dive on the mat or
::very deep Russian squats and come out feeling great with a hip FAI and two lumbar bulging discs.
::I really appreciate the ethos as I've pulled myself back from being an overly
::cautious teacher, but there are obviously aggravating exercises for certain conditions.
::There are a hell of a lot of things that I wouldn't do with a frozen shoulder, for example.
::I realize you're talking big picture and I'm happy to embrace the gist of it.
::I recently learned to be more optimistic about lots of shapes from Dr.
::Kelly Starrett. He says Pilates is the safest system there is.
::All right. So like I said, this is absolutely not to have a go at this person.
::That comment was absolutely fair enough question.
::And I want to do my best to answer that question here in an equally respectful
::way and to give it the depth that I think it deserves because I think there's
::a lot of depth behind this question.
::All right. So essentially, what a contraindication is, is something that you
::shouldn't do if you have a specific condition or injury.
::And contra comes from the Latin means against or opposite to.
::And we say that also in contralateral, meaning the opposite side.
::And indication is something that you should do for a condition.
::So for example, you should put a cast on a broken arm.
::So a cast is indicated for a broken arm. So a contraindication is something
::that you shouldn't do for a specific condition. Now,
::What a contraindication is not is just if you have pain when you do a specific
::position, if you have a specific condition.
::So for example, if you have a disc bulge and when you flex your spine,
::it hurts, that doesn't mean that spinal flexion is contraindicated for people with disc bulge.
::Now let me unpack this a little bit, please, because I think this is where a
::lot of people go wrong in their reasoning.
::And this is the old correlation does not equal causation or Mozart is a table
::and I'll explain what I mean by those in a second.
::So just say you have two disc bulges like the person commenting on that post
::said and you do deep lumbar flexion and it hurts your back.
::Well does that mean that deep lumbar flexion is contraindicated for people with disc bulge?
::Well maybe but what about all of the people who have two bulging discs who don't
::have pain when they flex?
::And what about the people who don't have disc bulges who do have pain when they flex?
::And what about the people who have disc bulges and are alleviated by flexion
::but feel pain when they extend?
::So just because one person has a particular symptom or even a group of people
::have a particular symptom and have a condition doesn't mean that that symptom
::indicates a contraindication for that condition.
::A contraindication is really something, think about it as something that if
::you did it, it will either worsen the condition or it's dangerous if you have the condition.
::And so there is a list, a short list of actual contraindications from the American
::College of Sports Medicine and various other guidelines that I'll share some of with you.
::But just having pain when you do a certain thing and having a condition doesn't
::make that movement or activity contraindicated.
::We know within, and there are probably two main reasons that I'm aware of for this.
::Well, probably three actually, three categories of reasons.
::The first one is that the relationship between pain and physiological findings,
::whether it's MRI findings, x-ray findings, CAT scan, etc.
::The relationship between pain and musculoskeletal findings,
::whether we're talking about disc bulge or FAI, femoroacetabular impingement,
::hip impingement, or whether we're talking about arthritis or whether we're talking
::about stenosis or spondylolisthesis.
::There are lots of different frozen shoulder, tendinopathy, tendinitis.
::There are lots of conditions that we can diagnose on a scan where the relationship
::between that condition and pain is unclear.
::And for example, in disc bulge, we know that disc bulge is very common in people
::without pain. So something like, there was a study by Brynjikji et al.
::In 2015, in fact, there were two systematic reviews by this group in 2015,
::and one of them found that disc bulge is essentially,
::prevalent in something like 20% of pain-free 20-year-olds, and then it goes
::up by roughly 10% a decade.
::So 30% of pain-free 30-year-olds, 40% of pain-free 40-year-olds, et cetera.
::And so if you're a 50 year old with no back pain there's a pretty there's a
::more than even chance that you've got a disc bulge and so you,
::Disc bulge is probably a better thought of as part of the normal aging process
::rather than a pathology or an injury.
::Now, the second Brynjikji study from 2015 did find that disc bulge is more common
::in people with back pain than people without back pain, but only slightly.
::So I can't remember the exact stats in front of me. You can just look it up.
::Brynjikji, B-R-I-N-J-I-N-K-I. K-J-I, I think, at L, 2015.
::And so there is a relationship between disc bulge and back pain because people
::with disc bulge have a higher rate of having back pain.
::So out of 100 people with disc bulge, 100 people without disc bulge, of age-matched people,
::there will be a substantial portion of the people with no back pain who have
::disc bulge if we MRI them, but a slightly higher number of people with back
::pain will find disc bulge.
::And so, you know, does disc bulge cause back pain? No, well,
::it obviously doesn't cause back pain because otherwise you wouldn't have 50%
::of pain-free 50-year-olds with disc bulge.
::If it caused back pain, those people would have back pain.
::Can it contribute to back pain? Yes, it very likely, almost certainly,
::does contribute to back pain.
::And so a better way of thinking about the relationship between these radiological
::findings, you know, disc bulge, spondylolisthesis, osteoarthritis, stenosis,
::scoliosis, many of these common findings that we think of as being sort of quote contraindications.
::And I'm going to put, with an asterisk, I'm going to put FAI in this basket as well.
::Is that the metaphor of the cup of resilience, and I can't remember where I
::got this from, it's a brilliant metaphor, I didn't make it up.
::And so what this basically, this metaphor is, I think it's a very useful metaphor
::for understanding how pain works and how it works specifically in musculoskeletal
::pain, so the conditions that I'm mentioning here.
::And that is that pain is not caused by any one single thing.
::And that we have a number of factors
::that we put in as stressors that will combine and will result in pain.
::So think of a cup being your, it's called the cup of resilience,
::and it's basically your ability to tolerate stress.
::And a stressor is anything that threatens your equilibrium, your homeostasis.
::So we pour in something into that cup of resilience. Maybe we pour in some tissue
::changes in your lumbar disc. you know, the disc wall is desiccated,
::there's a bulge out the back.
::Okay. So that's a stressor that we pour into that cup. And then we pour in some
::other, but that doesn't overflow the cup.
::And so you don't have pain. But then if we pour in some, you know,
::systemic inflammation and some obesity and some low physical activity and some
::poor sleep and some financial stress and some worry and some catastrophization about your back pain,
::well, then if we add up all of those things and that exceeds the volume of the cup.
::We pour in so much stressors that it overflows the cup and the overflow is pain. And so...
::Thinking about this metaphor allows us to reconceptualize pain as an output
::of the system when the system is overwhelmed with too much stress that it can't tolerate.
::And so in that situation, what can we do to help that person?
::Well, there are lots of modifiable things there. We can help them improve their
::sleep, their diet, their weight, their systemic inflammation,
::their exercise, their catastrophization.
::Can we do anything about the disc bulge? Well, we can address it with surgery,
::but we can probably get rid of their pain for most people or certainly minimize
::their pain by addressing most of those other factors.
::And if you think about this, if you've got an injury, you know,
::if you've got something that you've been thinking of as an injury,
::like a disc bulge or a tendonitis or a tendinopathy or arthritis or some other itis or osteopathy.
::Does it hurt exactly the same amount 24 hours a day?
::Almost certainly it doesn't. Most of these things overwhelmingly follow a pattern of.
::Regression to the mean, essentially. Pain's worse on some days, better on other days.
::And it tends to average out over a certain time. Or sometimes you have an episodic back pain.
::So, you might have back pain for a week or three or five, and then it goes away
::for months, and it comes back again at some later date.
::So, what happens there? If you have back pain that is episodic,
::do you bulge your disc and then it takes three to five weeks to heal,
::and then it's fine for six months and then you bulge it again.
::No, that's not how disc bulges work.
::A disc bulge doesn't heal in three to five weeks. So why does the pain go away
::in three to five weeks? Well, what happens?
::Yeah, probably just your body, whatever acute combination of stressors was overwhelming
::your system, you probably just get a bit better sleep.
::You start looking after yourself, all of those things.
::And over time, it just settles down and then you're fine for a while.
::And then next time you're not looking after yourself a bit, it kind of flares up again.
::And so that is a better model for understanding pain.
::So that means like if you, so then if we think about that and then think about
::the person who has disc bulges and has pain when they flex their spine,
::well, that doesn't mean that the disc bulge is causing the pain.
::And even more, even if the disc bulge was causing the pain, it doesn't mean
::that the pain indicates damage and that you are hurting the disc and making the condition worse.
::And in fact, we have zero evidence in live humans that flexing the spine worsens disc bulge.
::Now, we could say the same for FAI, femoroacetabular impingement,
::which correlates to two different kinds of findings in the hip.
::So we have what's called a cam deformity and what's called a pincer deformity.
::And a cam deformity just means the head of the femur, so the ball of the ball
::and socket, has a little kind of bump on it.
::And that bump, as the hip moves through the socket, that little bump can contact
::the lip of cartilage around the edge of the socket, the labrum,
::and can cause pain and damage to the cartilage.
::And then we also have a pincer deformity, and that is where the socket,
::the lip of the socket grows deeper and kind of forms like a pincer shape.
::And so the neck or the head of the femur contacts the lip of cartilage around
::the socket when it moves.
::So you'd think that if somebody had a pincer deformity where the socket is super
::deep and actually, you know, pokes out further beyond,
::you know, the edge of the socket, that lip of bone grows up really deep around
::the edge of the socket, that that would result in a lot more hip pain.
::Well, actually, paradoxically, we see there are quite a few studies now that
::have found looking where they do x-rays of people's hips and then they ask them
::about hip pain. And what they find is people with pincer deformity have less
::hip pain than people without pincer deformity.
::Now, how does that make sense? I don't know, but that is what we see.
::So now people with cam deformity have more hip pain than people without cam deformity.
::And people with what's called mixed morphology, which is pincer plus cam,
::also have less hip pain than people with no changes to the, you know, no cam and no pincer.
::So, for people with cam morphology, a little bump on the femoral head,
::femoral neck, that is correlated with higher amounts of pain.
::Now, there are lots of people with cam morphology who have no pain,
::and lots of people who have pain who have no cam morphology.
::So, does cam morphology cause pain?
::Probably not, but can it contribute to pain? Almost certainly, yes.
::But just because somebody has hip pain and has some kind of change to their
::non-typical structure of their hip doesn't mean the one causes the other.
::And also, even further, doesn't mean that the pain indicates you're doing damage to the hip.
::There are a couple of tests that are commonly used in the clinic to identify
::femorisotabular impingement. And this is, typically one is called the FADIR test, F-A-D-D-I-R.
::And that stands for flexion,
::adduction, and internal rotation. So basically, you lie on your back on the
::massage table, the treatment table.
::The physical therapist flexes your hip and knee and pushes your hip into flexion
::and internal rotation and adduction.
::And if that kind of creates a pinching sensation deep in your hip,
::then that is a positive Fadier test, which is said to indicate femoral acetabular impingement.
::But the problem is that this has a very high false positive rate.
::So what that means is basically everybody feels pain when you do that.
::So even if you don't have any change to your hip structure and you've got a
::completely normal standard hip structure with no cam, no pincer,
::it still hurts a lot of people to do that.
::So just the fact that that hurts doesn't mean that you have anything wrong with your hip.
::So, a lot of people are diagnosed, I think,
::with FAI by physical therapists and don't necessarily have a scan,
::but they're diagnosed with a Fadier test where it's just a false positive because
::basically everyone has pain there.
::Now, even if you do have diagnosed FAI with a CAT scan or an MRI or an x-ray,
::does that mean you should avoid hip adduction, internal rotation,
::flexion, which is the aggravating position for people with FAI?
::Well, yes, but it's not a contraindication. So what should, which brings us
::to, you know, what should you do for people with pain and injury?
::So to say something that's a contraindication we said before means it's,
::you shouldn't do it for people, for anybody who has a condition.
::So for everybody with this condition, we shouldn't do this thing.
::And the reason for that is for people with the condition, the contraindication
::will either worsen the condition or it is dangerous for people with that condition.
::Deep hip flexion doesn't worsen FAI and it's not dangerous for people with FAI.
::Now, is it painful for some people with FAI? Yes, it is.
::Deep spinal flexion doesn't worsen disc bulge and is not dangerous for people with disc bulge.
::Is it painful for some people with disc bulge? Yes, it is.
::And we could go on with a list of these things.
::We could say, for example, with frozen shoulder, external rotation and abduction.
::Doesn't worsen frozen shoulder and is not dangerous for people with frozen shoulder.
::In fact, the most effective evidence-based treatment for frozen shoulder is
::manipulation under anesthetics where you get a general anesthetic and the surgeon.
::That manipulates your shoulder into abduction external rotation forcefully.
::It's like almost dislocating the shoulder and that frees it up and it's quite
::an effective treatment.
::So far from being dangerous or making it worse, it actually makes it better.
::But is it painful? Yes, it is for a lot of people.
::So saying that something is painful is not the same as saying it's a contraindication.
::Now, it can be painful for a lot of people. It can also be not painful for a
::lot of people. A lot of people with disc bulge don't have a problem with flexion.
::A lot people with FAI, with pincer deformity, don't have a problem with hip
::adduction, internal rotation, flexion.
::So what's the distinction there? Well, we should, for all of these conditions,
::and I'm talking now about chronic pain conditions or chronic injuries,
::you know, out of the acute inflammatory phase, essentially,
::pain during exercise does not mean that you're damaging anything.
::So the general and we found uh there's there's a couple of really good studies from 2016,
::uh which i'll see if i can dig up and put in the show notes uh finding that
::painful exercise in the rehabilitation of chronic conditions is not more dangerous
::or less effective than non-painful exercise in fact in the short term painful
::exercise is actually more effective but in the long term it's no more or less effective.
::So just the fact that you feel pain when doing an exercise, if you have a chronic
::condition or, you know, chronic post-surgery or post-injury,
::doesn't mean that that movement's contraindication.
::So what we need to do then is base our...
::Our exercise choice on pain tolerance, right? Which just means like,
::does the client want, are they okay to put up with the pain, right?
::I mean, and that's going to depend on the person and what their goals are.
::And so if the person's, if the pain's really bad and the person doesn't want
::to have that sensation, well just, sure, avoid deep inflection.
::If somebody has pain when they deeply flex their hip or deeply flex their spine
::or abduct their shoulder or whatever, like, fine, don't, don't do that thing.
::But that would be the case regardless of what their diagnosis was.
::So if someone came in and they had no diagnosis of hip FAI and they had severe
::pain on hip flexion, adduction, internal rotation, I mean, it's just common
::sense that you wouldn't do that movement.
::Not because you're worried about damaging them, but just because like,
::if, you know, like if it really hurts when you poke yourself with a pin,
::it's like, well, don't poke yourself with a pin then. It's just kind of common sense.
::But if they are happy to put up with the pain, for example, an athlete who's
::training for an event or whatever, their motivation to do the movement is more
::powerful than their motivation to avoid the pain.
::Well, there's no danger in doing painful exercise in a chronic condition.
::This is assuming it's not an acute injury.
::Now, there is a slight caveat to that, that if you push into the pain a lot
::over an extended period of time and if it reacts by becoming inflamed or more
::painful after training for like more than 24 hours, it doesn't settle,
::then you should take a break for a day or two and then just go a little bit easier next time.
::So that's called the 24-hour rule and that comes from tendon,
::tendinopathy rehab. Okay.
::And when something is in the acute inflammatory phase, so essentially when it's
::red, hot and swollen, you know, within the first few weeks post-injury,
::post-traumatic injury or post-surgery, we should not push into pain in those situations.
::But aside from that, it's generally perfectly safe to push into pain.
::And that painful exercise does not indicate, it's contraindicated.
::Now, there are a few situations where there are contraindications.
::And it's a very short list. In the ACSM guidelines, for example,
::for people with osteoporosis, so low bone mineral density in their spine,
::end-range bouncing and loaded spinal flexion extension rotation is contraindicated.
::For pregnant women, contact sports are contraindicated because of the risk of
::blunt trauma to the abdomen.
::There's a very, very short list of things that are in fact contraindicated,
::both of those because they're thought to be done. Now, the blunt trauma obviously is dangerous.
::But in osteoporosis, actually, interestingly, that contraindication is not based
::on any evidence that we have. It's just based on expert opinion.
::But no one's going to get ethical approval to do that study of let's flex a
::bunch of people with osteoporosis and see if they get wedge fractures.
::So we just avoid loaded flexion for those people because we think it's probably dangerous.
::But that list is very, very short. And almost all of the conditions that you
::were probably taught in Pilates school or on Instagram to avoid certain movements
::for, like disc bulge, spondylolisthesis, arthritis,
::FAI, tendinopathy, rotator cuff tears, frozen shoulder,
::sacroiliac joint, quote, dysfunction, which is just a made-up condition, um, and.
::Patellofemoral pain syndrome. And if you think about any condition that's to
::do with muscles not working how they should, that's definitely a made-up condition
::unless we're talking about a genuine paralysis of muscles.
::All of these, even things like sciatica, radicular pain in the arm,
::in the leg, all of these things fall under the category of non-specific pain.
::And there are no specific contraindications for non-specific pain.
::The guideline is to remain as active as possible and to be guided by symptoms.
::So basically within pain tolerance, what the client is prepared to put up with,
::depending on what their goals and psychological makeup are, but that we should
::avoid the use of alarming diagnostic labels based on pathoanatomical terminology. technology.
::So rather than labeling them as you have a disc bulge, just say,
::okay, you've got some back pain. It hurts when you flex, so let's avoid flexion for now. Okay.
::And the best practice in rehab is to let it calm down by avoiding the painful
::stimulus for a little bit, and then gradually reintroduce that painful stimulus
::and build up a tolerance to it.
::You can in fact build up the tolerance to spinal flexion or hip flexion or knee flexion.
::Now, if you've got severe osteoarthritis in your knee, you're probably never
::going to regain your full deep
::knee flexion, right? Because there are physiological changes in the joint.
::But if you're avoiding a position because of pain, you probably can increase
::your range into that movement,
::maybe not back to the full original range that you had if there are pathological
::changes within the joint, but you can reduce the pain inhibition of that movement
::and the pain avoidance of that movement probably over time.
::And that typically flows into how we think about rehab anyway.
::So if you actually have an acute injury after the acute phase,
::when the inflammation starts to subside,
::essentially in the initial phase, during the inflammation, you want to avoid
::the position or the movement that caused the injury because you're very vulnerable
::to that position. That's what injured you.
::But then over the course of rehab, you need to gradually reintroduce that position
::or movement and start to load it increasingly and move it through larger range
::and higher speed because the whole, what rehab is, is rebuilding your capacity
::and tolerance to that position.
::And if you can't tolerate that position, if you have to avoid that position
::for the rest of your life, or you haven't been rehabbed.
::So the poison is the medicine in rehab.
::It's not, if you injure your back flexing it, the answer is not to avoid flexion
::for the rest of your life.
::The answer is to avoid flexion whilst in the acute inflammatory phase,
::and then gradually, gently reintroduce small range unloaded flexion and gradually
::increase the load in the range over time to build up a tolerance to flexion,
::strengthen the muscles, the ligaments, the tendons, the tissues involved,
::calm down the nervous system, reduce the threat level until you can tolerate
::high levels of flexion without pain or injury.
::And the way you do that is you gradually, progressively expose that body part
::in the system to the stressor.
::And that is what rehab is, increasingly
::loaded exposure to the original stressor that caused the injury.
::All right, dear listener, I hope that helps. I hope you find that interesting.
::To summarize, 99% of the contraindications you were probably taught in Pilates school are not.
::A contraindication is something that you should avoid for all people with a
::condition because it either worsens the condition or is dangerous for people with that condition.
::Just the fact that someone has pain with a certain thing when they have a condition
::doesn't mean it's a contraindication.
::But it doesn't mean that you have to push into the pain. You can just work with
::the person and say, okay, do you want to keep going?
::Are you prepared to put up with that pain or do you want to switch to a different move?
::And depending on their goals, and if you de-threaten it for them,
::say, hey, look, this is not causing damage.
::It's totally safe, but pain's not fun. So do you want to keep doing this move
::or do you want to switch to a different move?
::And just the fact that they have pain doesn't mean that that's a contraindication
::because there might be another person with the exact same diagnosis who doesn't
::have pain with that movement, or there might be another person with no diagnosis
::who has a very similar symptom.
::So that is an individual thing and we have to do on a case-by-case basis.
::So if someone has pain with a certain movement, you negotiate with that person
::about whether they want to keep doing that movement or switch to a different
::version, but that doesn't mean it's contraindicated.
::Okay, dear listener, thank you very much, much love, and I will see you in the next one.
