How to create your very own evidence base … in a post truth World


"At one time we had truth and lies. Now we have truth, lies, and statements that may not be true but we consider too benign to call false." Ralph Keys

 

 
 
Hurrah! I hear you say (unless you are a member of the AACP that is … acupuncture is not recommended as a treatment for back pain) the new NICE Guideline - Low back pain and sciatica in over 16s: assessment and management has just been published. That means a group of experts have successfully completed months/years of hard labour, poring through evidence to produce a thorough carefully worded (italics for emphasis) analysis and clear guidance.



Of course, it doesn’t stop there! Then we get commentary and analysis via bloggers. Here’s an example of a nice balanced piece by Neil O’ Connell who was a member of the guideline committee. KarenMiddleton added her view on how the guideline marks an important moment for the physiotherapy profession, emphasising the ‘opportunity to evolve and look again at practice and re-evaluate what is best for patients.’ … the guideline gives clear wording (italics for emphasis) on that, and naturally is disappointing for some, yet welcome to others.

Naturally, as is the way of the World, we get the bloggers, sceptics and Twitterati who also helpfully summarise the guideline, and it is here where things begin to get a little messy. What is clear, to us all in the ‘modern World’ is that there is little time to read long documents, and it is human nature to look for short cuts (so far so good). So in many fields such as medicine, pharmacy and physiotherapy we have the rise of the ‘infographic’ … 

Now, don't get me wrong here, infographics are brilliant, because they are short snappy and summarise long papers in one interesting and attractive figure. I you’ve never seen the work of Yann Le Meur … then you should. The artistry, accuracy and attention to detail, is both impressive and incredibly useful to visual learners. 

HOWEVER

not all infographics … how shall I say … meet this exacting standard.


It became apparently obvious to me, that writing an infographic allows the writer to interpret something like a guideline, pretty much any way they want (just as Bloggers and internet commentators do), Herein, lies the rub …

IF the infographic writer, for one reason or another, chooses to alter the emphasis or wording, miss bit out, or get bits wrong … then the reader or recipient can be easily mislead. 

So, you end up with a snap-shot that can misrepresent the original document. Which of course, means that ANYONE can create their own version of the evidence base via the medium of the infographic.

HERE the fun begins!

Below I’ve written a short infographic (well ... some text and a picture) to help anyone create their own evidence base. If you follow the simple instructions, you can make any, paper review, guideline or article say exactly what YOU LIKE … it is a miracle! 


Try it yourself, adjust your favourite intervention, be it CBT, exercise, massage into a slightly bigger font or place on the positive side of the table/graph/pie chart in a slightly bolder colour etc. alter a word here and there (for emphasis/de-emphasis) and before you know it, you’ve changed the message of the original. You can even miss stuff out if you like, say radio frequency denervation or manual therapy (it is entirely your choice), if that’s is something you don’t particularly subscribe to.

Indeed ... if someone from the AACP had thought of it they could have re-inserted acupuncture into the LBP guidelines and lots of folk would never have noticed (cos’ they don’t have time to read the source document). That would of course, be disingenuous, but hey ... politicians do it daily, and we wouldn’t have had Iraq, Brexit or Donald Trump without a little (or more) distortion of the truth.

Where does this leave us? And why did I even bother to put pen to paper?

Well it requires us to have a realisation that we are in the ‘post-truth era’ as detailed so well by Ralph Keyes in his book The Post-Truth Era:Dishonesty and Deception in Contemporary Life. Keyes states:

‘At one time we had truth and lies. Now we have truth, lies, and statements that may not be true but we consider too benign to call false. Euphemisms abound. We’re “economical with the truth,” we “sweeten it,” or tell “the truth improved.” The term deceive gives way to spin.  At worst we admit to “misspeaking,” or “exercising poor judgment.”  Nor do we want to accuse others of lying.  We say they’re in denial.  A liar is “ethically challenged,” someone for whom “the truth is temporarily unavailable.”’ Ralph Keyes

Furthermore he states …

‘We can only understand the motives of such dissemblers by examining the sea in which they swim. Trends ranging from the postmodern disdain for “truth” to therapeutic non-judgment encourage deception. There is much incentive and little penalty for improving the “narrative” of one’s life. The increasing influence of therapists, entertainers, politicians, academics, and lawyers, with their flexible code of ethics, contribute to the post-truth era. So do ethical relativism, Boomer narcissism, the decline of community, and rise of the Internet.’

So there you have it folks … we have to adjust our radars, improve our awareness, be on our guard, even occasionally take the time to read a source document. Because, sometimes those nice folks who wrote that blog may just have written it to fit their own biases, or particular agendas, and in the same way, the handy visual snapshot of reality ... the infographic ... has sadly fallen foul of exactly the same concept. 

The dissemblers are amongst us, and I truly don't know why they behave that way.

Now  ... just a brief word on sceptics ... AND pseudo sceptics

The medical World has its fair share of sceptics or skeptics (as they are known in the USA), Ben Goldacre of Bad Science, is perhaps one of the most well known examples, Edzard Ernst is another. These brave souls, speak out on any issues from, basic bad science, global warming, Government policy, Prince Charles and his promotion of homeopathy, through to the risks of spinal manipulation etc. 

Good sceptics adopt an open minded approach and use science, debate, exposure (of bad practice) and apply critical examination and inquiry to all sides (including their own). 

Here's an example; Ernst has been a long time critic of alternative medicine (AM), and frequently adverse events (e.g. death after SMT) and general poor scientific practice relating to all sorts of disciplines within AM. These range from the more unconventional stuff like 'energy healing', and 'spiritual healing', through to say 'slapping therapy', and perhaps the more conventional, such as acupuncture. As such, he is commonly aggresively vilified and challenged by proponents of such therapies. His response is kindly, gentlemanly debate (often in the face of virtual abuse), use of science, critique, statistics etc. BUT when evidence comes along to challenge his World view on a topic, he has the good grace and conduct, to modify his view according to the developing and changing evidence base, or at the very least, air that evidence. 

Of interest to some physiotherapists (either historically or practically), MASSAGE had been a target of his for a number of years, until a new paper caught his eye and he wrote this and then later, this. Ernst is an example of how a GOOD honest sceptic is able to adapt their paradigm to new evidence and update their hypotheses to fit the data. In physiotherapy, SOME of our emerging breed of bloggers, podcasters and self-proclaimed sceptics are able to do that, and do it very well. SOME appear to default to the habits of pseudo-sceptics.

Pseudo-sceptics ... tend to:
  • Persistantly judge as false, and debunk anything that contradicts their paradigm.
  • Are partially interested in truth, evidence and facts, but MORE interested in defending their own views/stance.
  • May fail to update their paradigm to incorporate new evidence, and deny or bury data which doesn't fit their view.
(Source http://www.debunkingskeptics.com/characteristics.php)

Sceptic or denier?

'A sceptic will question claims, then embrace the evidence. 

A denier will question claims, then reject (or bury) the evidence....'

and for a brilliant commentary on pseudo-skepticism by Marcello Truzzi go here.

So be on your guard people … it's a tough environment out there, and distinguishing truth from fiction in a post-truth World ain't easy ... false news, pervades every aspect of the internet, even those sources, you thought you could trust, AND relies entirely on a passive (non-thinking) click of a button. Those who use it to their advantage know that, and you should too ... if you don't already! 

After all, that is what brought us Donald Trump. Good luck folks.

I’ll leave you with the wise words of Ralph Keyes who vocalises this much better than I ever could …

‘Post-truthfulness builds a fragile social edifice based on wariness. It erodes the foundation of trust that underlies any healthy civilization. When enough of us peddle fantasy as fact, society loses its grounding in reality.  Society would crumble altogether if we assumed others were as likely to dissemble as tell the truth. We are perilously close to that point.’ Ralph Keyes

Be careful out there folks … words matter, and semantics are important AND that is the TRUTH

10 Good reasons why physiotherapists are perfectly placed to deliver exercise prescription.

A Physiotalk Tweet Chat recently posed the question ... 'Is exercise at the heart of Physiotherapy?' ... and that got me thinking!

So here is my take on that ... written in a mini-blog and offered up as a SlideShare version for those who prefer that sort of thing.





Here are 10 good reasons why physiotherapists are perfectly placed to deliver exercise prescription.


1.    Specific knowledge of exercise physiology and sports science
2.    Specific knowledge of neurology
3.    Specific knowledge of MSK pathology, co-morbidity and disability
4.    Specific knowledge of the respiratory system
5.    Specific knowledge of biomechanics
6.    Specific knowledge of pain science, and the ability to communicate strategies for behavioural change
7.    Specific knowledge of the psychological, mental health and societal  implications of injury/illness/dysfunction
8.    The ability to progress and modify exercise prescription to meet mutually agreed goals/targets
9.    The ability to develop exercise prescription to meet agreed functional needs

10.  The ability to modify exercise prescription to meet the need of all age groups and levels of aspiration.
 

Question is … Are we using a ‘system based approach' and leading the pack? … or simply too busy sniping from silos?


I have some thoughts about that ... but I think we should concentrate on directions for the future ... for physiotherapy and exercise prescription. 



 

1.    Step outside your silo ... and lay down your guns! Firing at others is a waste of time and energy ... save it ... or your performance will suffer!

2.    Concentrate on integrating and sharing the knowledge


3.    Spend more time and energy on what DOES work


4.    Consider exercise prescription as a powerful TREATMENT MODALITY


5.    Develop and promote a ‘Systems based approach’ to exercise prescription, which incorporates all of the above


6.    Exercise your minds … Become leaders NOT followers

The art of ‘naysaying’ …evidence based practice and whiplash associated disorder


So first of all, what is a naysayer?

Well, the Merriam-Webster gives the following definition – “a person who says something will not work or is not possible: a person who denies, refuses, or opposes something”
The Urban Dictionary definition is somewhat lengthier and perhaps more revealing:
“One who frequently engages in excessive complaining, negative banter and/or a genuinely poor and downbeat attitude.”
They continue … “Naysayers are distinguished by their tendency to consistently view the glass half empty, make frequent one-way trips to negative town, and constantly emphasize the worst of a situation. They have the keen ability to spread their pessimistic attitude to a group of unsuspecting bystanders and encourage others to employ their mind-set.” 

From a behavioural perspective they suggest that “Naysayers … will stop at nothing to bring a general sense of negativity to any situation.” 

 

BUT … What has this all got to do with Physiotherapy and evidence based practice?


 

Because it is EASY to be a naysayer in the tiny World of evidence based medicine (EBM) or practice (EBP). We seem to be beset by a veritable queue of them, some aspiring desperately to be the next EdzardErnst (he made a career out of it … and still does!) within their own ‘specialist’ domain. 

 




Physiotherapy (PT) has not escaped this trend. There is an increasing army of bloggers (he said from his blog … such irony!) and Twitterati, who now peddle their view of the World. They utilise the latest evidence, to back up their statements and often negative rants about WHAT DOESN’T work in PT (Yawn! If you haven't seen one, don't go looking for one ... you could end up writing a blog!). 
They pre-empt criticism, by cleverly suggesting that anyone who disagrees  with their interpretation of the the evidence, is either ‘unscientific’, a ‘fool’ or perhaps a ‘curmudgeon’, thereby discouraging discourse or opposing views from the outset.
…and so what?  I hear you ask!
PT has come a long way in the last decade or two, in terms of its use of the evidence base, to drive treatment interventions and mould out-dated thinking and practice. As each day goes by we find more and more studies, which guide the way we treat and rehabilitate our cases. 

Of course, it can be very puzzling and even soul destroying for clinicians to find that a mode of treatment which they believed was ‘effective’, is suddenly found by the latest study to have little or ‘no effect’ ...BUT that's life, it makes us stronger!

A good example is the recent publication in the Lancet, which suggested in its ‘Interpretation’ section … “We have shown that simple advice is equally as effective as a more intense and comprehensive physiotherapy exercise programme.”

 

This type of conclusion ... naturally comes as a body blow to clinicians, many of whom have an inherent faith in the belief that their interventions are doing good. 

 




So just when you were feeling a little vulnerable ... ENTER THE NAYSAYER! … Usually a confident and bold academic type, who with all the guile of Jeremy Clarkson in a dog naming competition
...explains gleefully in a detailed blog, that, ‘actually folks you got it all wrong’ ... which of course he/she knew all along … and which is now ‘evidenced’ by the latest trial!


Brilliantly done and incredibly EASY … BUT WHAT IS THE POINT?
Answer … There isn’t one!
… Though they WILL say, they are disseminating information … updating us all on the latest evidence. 

Errr maybe … OR it could be argued, gleefully exercising blatant ‘told you so’ promotion of their own Worldview. 

Naysayers seldom offer a pragmatic alternative ...

Academics have the luxury of being able to access, read and analyse the latest research and some do that brilliantly, as do many clinicians. As a result there is a plethora of blogs, which are designed to be genuinely helpful to clinicians and academics alike, and give thoughtful interpretations of contemporary evidence, which can be translated into practice. The sportsphysio is one excellent example, rogerkerry.wordpress is another.
Thankfully, as the Urban Dictionary helpfully suggests, naysayers are, “Not to be confused with non-naysayers … who fight against the negativity brought forth by naysayers, make the best of a situation and are not afraid to call out a naysayer on the spot.”
My personal advice to busy clinicians is to seek out the pragmatic NON-NAYSAYERS (like those mentioned above and here). Those who have the ability to construct rather than deconstruct their own profession, whilst at the same time, embracing the concepts of contemporary science and evidence based clinical practice. 

Change is required, but not via the medium of lofty negativity.

On the subject of whiplash injury

This is NOT a trivial subject … The emerging science is welcome, it is clear that PT’s will need to look carefully at current practice in the light of contemporary studies relating to Whiplash Associated Disorder. 

Prof Michelle Sterling herself, suggested a PT role in assessment, sub-grouping, early recognition of PTSD and triage (for early cognitive behavioural therapy) may well be sequelae of the groups latest findings. 
Using Michaleff et al’s study as an example, DON’T FORGET ... it only looked at one particular ‘pragmatic exercise programme’ ... devised by 'experts' YES, but was it the right type of rehab, applied at the right time? 
In other words, in the same way that the emerging research has guided our thinking on best practice in ACL rehab for example, it may well guide us further in the field of WAD.


DO NOTE (because the naysayers may have missed it ...) the final paragraph in another Lancet Article relating to WAD and exercise… 

 “… These findings should NOT be interpreted as encouragement to abandon exercise therapy in these patients: ... the question is HOW & WHEN to exercise people with chronic whiplash-associated disorders.” (upper case, for non-naysayer emphasis) 

Academics might dwell for a moment on this statement from Nijs and Hickman 2014 ... 

"Physiotherapy curricula are only starting to integrate cognitive behavioural therapy as part of pain management modules ... Future physiotherapists might have the necessary attitudes, beliefs, and skills to apply specific cognitive behavioural therapy rules during exercise therapy for chronic pain patients, including those with whiplash-associated disorders."

FINALLY clinicians, ask yourself honestly … (with or without CBT) when was the last time you REALLY applied resistance to cervical spine musculature during neck rehabilitation?  ...and more importantly, would it make any difference to outcomes?

The jury, on those particular questions will remain out for some time.  

REMEMBER pendulums swing!
