Core, Crunches, & Oversimplification

There is a wealth of information on the core, spinal loads and biomechanics, and appropriate exercise selection. Despite this, there are no perfect, uniform laws of core training. There are some great principles and guidelines, but there are no unbreakable laws. Perhaps in our desire to communicate the ills of repeated, loaded spine flexion some of us have oversimplified this concept.  Such as don’t flex the spine and don’t do crunches.  (I know I may be guilty of this, and in doing so failed to follow one of Einstein’s cautions.  I admit my bias is due to working with a large population of folks with back pain and a great number of athletes/weekend warriors who spend there days in seated flexion during desk work.)  Please note that I am not advocating for or against the crunch, sit up, leg lift, V-up, or any other particular exercise, just a reconsideration of what we know, how we train, and what we say to people about their movements. Perhaps a more complete, reasoned approach is warranted.

Make things as simple as possible, but no simpler.  – Albert Einstein

 

Paraphrasing Stuart McGill, ‘there are no good or bad exercises‘.  We need to find the right exercise for the right person at the right time.  In my opinion this is best done with a constant monitoring: assess, implement training strategy, reassess (within visit and over time).

What does your core training produce? Quality? Capacity? or Both?

I would argue for the novice trainers and clinicians to avoid spine flexion with their patients/clients (particularly loaded or repeated) may be advisable as the yearly and lifetime prevalence of back pain is quite high, 40% and 85% respectively.  However, the more seasoned should take a careful look at the individual, their activities and demands, and then weigh the risks and benefits.  Below are links to an interesting discussion on this, it is 3 parts of a well reasoned, collegial blog conversation.

Side note: I’d like to applaud both authors for stating their points with their own clinical and scientific understanding, reasoned arguments, and interesting perspectives, rather than sinking to the level where some online disagreements tend to go all to quickly..

Side note #2:  The discussion above represent my thoughts and is not intended to summarize the posts below.

Use the links below for a great discussion about appropriate training of youth athletes, the limitations of certain approaches, and finally the multitude of factors that influence appropriate training (particularly in the female athlete).

Things to consider:

  • What factors govern your exercise selection?  Age? Gender? Injury history?  Activity/sport?  Frame size?  Disc shape?  Related mobility (hips/ankles/thoracic)?
  • Are there patients/clients who should avoid spine flexion?
  • Are there folks who should be encouraged to flex?
  • When training flexion how much repetition or load is reasonable?
  • Should training recreate the demands of the sport/activity?
  • Should training prepare someone to resist the loads of their sport/activity?
  • Is core training the same for the male and female athlete?

This week’s inspiration

Some things that have brought a smile to my face and renewed enthusiasm to my day.  Very proud that some of these come from R2P, the student arm of the International Society of Clinical Rehab Specialists.  Top notch work by these students.

  1. PT’s vs Chiro’s blog post from From Jas Randhawa & Kyle Balzer (future DC and future PT).  Interesting discussion getting a lot of views.  Look for the upcoming Movement Lecture.
  2. Great Regional Interdependence and R2P intro from Ramez Antoun (future PT from UMass Lowell). first 25 minutes or so are fantastic.
  3. In Sickness and in Movement.  Be prepared to be inspired. 
  4. The difference between winning and succeeding with John Wooden.

Addition by subtraction

I had a new patient enter the office recently who had been under the care of another chiropractor.  This was an interesting visit as often times when a patient comes from another health care provider there is a reason.  Perhaps they are in some way dissatisfied, not improving as fast as they would like, have a new condition, recently moved, etc.  This one was different.  The patient was thrilled with their current health care provider.  You may be thinking the same thing as I was, “why make a change when you’re extremely satisfied?”.  Here’s the answer I was given (paraphrased):  “I love my current doctor, but cannot drive all the way to see him more than 1x/week due to gas prices and time.  I’ve had these symptoms for 3 months, I lived with it for 8 weeks and then have been receiving treatment 1x/week for the past 4 weeks.  I am gradually getting better, but if I could be seen more often, I would get better faster.”   Sounds logical, if some is good, more must be better.

Patient history includes back pain and left sided leg symptoms (S1 sensory changes).   No signs of ominous pathology.
Prior treatment: weekly instrument assisted manipulative therapy with mild improvement each week.  Patient was also stretching at home.

So at this point the question is what to do.  First, I’ll say that  when I take over care for a patient who believes their current treatment regimen is working, I rarely change it initially unless I have significant concerns.  I instead work with it and make gradual changes in most cases.  I believe that what the patient thinks will make them better often does.  Their confidence in their treatment is an important part of the puzzle. (Is this approach right or wrong?  Feel free to weigh in.) 
Next issue is what to change in the treatment to make it more effective… the frequent debate is with whether to mobilize or stabilize first.  From Boyle’s Joint by Joint approach we have some general guidance as to what tends to need to be mobilized and what areas tend to need stability.  From FMS/SFMA (& others) we have the general concept that mobility is necessary before stability.  While I agree that mobility is often needed first, this is not a rule as much as it is a guideline.  Frequently, I’ve seen that providing stability where needed allows the nervous system to reduce the ‘tightness’ of other areas.  As stability is restored, the nervous system stops drawing upon ‘prime movers’ to act as stabilizers and mobility is restored.  To determine what type of treatment is most likely to benefit an individual patient, I follow this model, as outlined by Dr. Craig Liebenson.  Its brilliant simplicity is applying a McKenzie (MDT) concept to active care, including mobility & stability exercise.  While the mobility vs. stability debate will continue on, there is a more important first step that is at times overlooked. So let’s go back to this patient I saw and the case at hand.  I did provide instrument assisted manipulative therapy, similar to what the patient had previously received.  The patient was satisfied with this portion of care.  I also reviewed the patient’s current stretches.

After realizing that the patient was performing positions that involve common back injury mechanism (repeated or prolonged end-range loading, in this case lumbar flexion), I simply asked that she stop doing 2 of the 4 stretches the patient was doing on her own each day to try and remedy her condition.  (Picture on right was #1, a seated version with legs spread was #2.)

The outcome:  Patient returned 2 days later and was 50+% improved.  After 3 months of symptoms, I consider that a positive outcome.  Please realize, this is not a post about me, how good a job I did, or the quality of care I strive to provide.  It is also not a post to say, look at what someone  else was doing wrong.  (I hate these types of blog posts and FB posts.  We’re all on the same team.)  In fact, if you reread this you’ll see that I actually did very little.  I simply duplicated someone’s treatment.  The only thing that was changed is I followed the advice of one of the Prague school pioneers.Karel Lewit

“The first treatment is to teach the patient to avoid what harms him.”  Karel Lewit, MD

Patients who are not well informed as to what harms them are unlikely to respond favorably. Removing offending movements, positions, and activities is essential.  Sparing advice trumps mobility, stability, balance, etc.  (In reality it often includes bits and pieces of all of them.)  At times patients have a hard time understanding how important and powerful this part of treatment is.  I’ve heard and use the following story, “If you came here with thumb pain, I could treat your thumb any way imaginable, but if it hurt because you were hitting it over and over again with a hammer, wouldn’t you agree that teaching you to swing the hammer differently is most important?”  Change hammer & thumb to anything that resonates with the person in front of you and I think you’ll have a productive first interaction.

Don’t skip step 1:  ”Teach the patient to avoid what harms.”  (Added note: Don’t let step 1, become ‘avoid activity’, be specific.)

Sparing strategies:

A) For repeated movements: ergonomic advice, teach/train better quality movement, and improve joint centration. 

B) For prolonged loads: microbreaks.  If you stand, sit. If you sit, stand.  Examples:  Brugger’s postural relief position.  McGill’s overhead reach.  McGill's overhead reach

Wellness & Nocebo Paradox

What do wellness and the nocebo have to do with one another?  Very little.  But an odd paradox arose today, which prompted me to sit down and write a little rant.  My hope is that we all begin to think more about what we’re doing and how it impacts the end result, rather than just continuing our current routines.

Recently I had a patient whose case looked like one I’ve seen hundreds (perhaps thousands) of times before.  The classic case every practitioner who treats back pain knows so well.  Patient reported with low back and buttock pain with no true radicular symptoms following a series of repetitive flexion activities.  A common condition, from a common cause.  A common solution was found and was successful after reassessment.  But there’s more to the story.

As worked with this patient I was aware that she had been to another chiropractor and was dissatisfied, prompting her to seek my care.  I didn’t ask much about what was done previously.  After I was done treating her, the patient showed me a written report from the previous chiropractor.  The written list included a multitude of ‘abnormal’ exam findings from range of motion limitations to pelvic unleveling and torque. It also included imaging findings of disc space narrowing and spinal decay (diagnosed by x-ray), numerous subluxations, areas of trigger points and spasm, abnormal spinal curvatures, and likely others I’m forgetting.  While I acknowledge these findings are likely accurate (and commonly reported by many chiropractors), I question 2 things.  1) There importance considering until a week ago the patient was smiling, happy, & healthy.  2) The way they are presented.  We are seeing more & more that presenting people the idea that something is wrong can be very disabling.  This is called the nocebo effect.  If you tell someone something is wrong, it often becomes a self-fulfilling prophecy.

“For each ailment that doctors cure, they introduce ten others in healthy individuals by inoculating them with a pathogenic agent, thousands of times more virulent than any microbe- the idea that they are ill.”  – Marcel Proust, The Guermantes Way
This is not to say that we don’t need to tell patients of their exam findings, just that we need to be mindful about how we do it and why we do it.  To use a cliche, you are presenting patients with a glass of water, you can choose to tell them it’s half full and this is how we fill it up more, or that it’s half empty and this is dangerous because it will eventually be even more empty.
For those who know this is a common occurrence, here’s what made me write about this today.  There is a complete paradox here that often goes unspoken and is rarely discussed.   The same chiropractor who imparted all of these ‘ills’ upon the patient, is a chiropractor who promotes ‘wellness’.  The disparity between telling someone they have a multitude of maladies and then trying to sell them wellness care is enormous and frankly doesn’t make sense.  Perhaps this is the break them down and build them up strategy we see in military training and coaching?  But I don’t believe it has a place in health care recommendations.  Using what equate to scare tactics creates a nocebo effect.  While fear is a good motivator, hope and opportunity are much better.  Fear gets people to do ‘just enough’.  Hope and opportunity will foster an environment where someone becomes self-empowered to work beyond the bare minimum.  If we want people to strive for ‘wellness’ our first move can’t be convincing them they’re ill.  (Feel free to reread Proust’s quote above)

Wellness defined:  Wellness is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity. – World Health Organization

Before you give examination or test results, think about the effects of how you present the information.

Nocebo defined:  a harmless substance that when taken by a patient is associated with harmful effects due to negative expectations or the psychological condition of the patient.

  • Keep in mind that ideas and perception are the driving force behind the nocebo effect.  Giving someone the idea that they are not well, or may not be well in the future is what creates symptoms, not the sugar pill or saline injection.  Thoughts, ideas, and poorly delivered diagnoses or reviews of findings can create disability and illness.

This has been common knowledge for some time, but has not been put into clinical practice.  It has been studied and written about in the general media. The nocebo is real. “in double-blind clinical trials of antidepressants, even those participants receiving a sugar pill report side effects like gastrointestinal discomfort if investigators have warned them at the outset that those effects are likely.”from The Nocebo Effect Time Magazine in 2009.  Also in the Huffington Post, read about pessimism and the nocebo.

Lateral Stabilizers and Transverse Plane Exercise

Quadratus Lumborum

Can you see the stabilizing, connecting architecture.

We know that no muscle works in isolation and the brain thinks in terms of movement, not muscles.  So I think the title of these videos (and articles) may be misleading for those who are not familiar with the paradigm and principles that support it.  Despite calling it QL training, you will notice very quickly that Dr. Liebenson & Chad Waterbury are training patterns and functional whole body exercises, not working to isolate an individual muscle.  Keep in mind our common movement patterns as you review this and realize how neglected that lateral direction or transverse plane can be.  So far today I’ve spent 95+% of my time moving forward on level surfaces.  My activation of the lateral stabilizers has been minimal.  Our modern society and common training exercises necessitate evaluation of this plane and likely incorporation of these exercises into most routines.

A great introduction, now see how it’s done.

Some addition reading: on Dr. Liebenson’s blog  & Chad Waterbury’s blog.
Also a previous post by Dr. Cubos on Gluteus Medius activation which includes the role of the QL.

We must assess all planes and all movements.  Treatment is the applied to the worst, pain-free pattern (treat the abnormal motor control that improves the mechanical sensitivity).
