spinal manipulation

This study describes the use of so-called alternative medicine (SCAM) among older adults who report being hampered in daily activities due to musculoskeletal pain. The characteristics of older adults with debilitating musculoskeletal pain who report SCAM use is also examined. For this purpose, the cross-sectional European Social Survey Round 7 from 21 countries was employed. It examined participants aged 55 years and older, who reported musculoskeletal pain that hampered daily activities in the past 12 months.

Of the 4950 older adult participants, the majority (63.5%) were from the West of Europe, reported secondary education or less (78.2%), and reported at least one other health-related problem (74.6%). In total, 1657 (33.5%) reported using at least one SCAM treatment in the previous year.

The most commonly used SCAMs were:

  • manual body-based therapies (MBBTs) including massage therapy (17.9%),
  • osteopathy (7.0%),
  • homeopathy (6.5%)
  • herbal treatments (5.3%).

SCAM use was positively associated with:

  • younger age,
  • physiotherapy use,
  • female gender,
  • higher levels of education,
  • being in employment,
  • living in West Europe,
  • multiple health problems.

(Many years ago, I have summarized the most consistent determinants of SCAM use with the acronym ‘FAME‘ [female, affluent, middle-aged, educated])

The authors concluded that a third of older Europeans with musculoskeletal pain report SCAM use in the previous 12 months. Certain subgroups with higher rates of SCAM use could be identified. Clinicians should comprehensively and routinely assess SCAM use among older adults with musculoskeletal pain.

I often mutter about the plethora of SCAM surveys that report nothing meaningful. This one is better than most. Yet, much of what it shows has been demonstrated before.

I think what this survey confirms foremost is the fact that the popularity of a particular SCAM and the evidence that it is effective are two factors that are largely unrelated. In my view, this means that more, much more, needs to be done to inform the public responsibly. This would entail making it much clearer:

  • which forms of SCAM are effective for which condition or symptom,
  • which are not effective,
  • which are dangerous,
  • and which treatment (SCAM or conventional) has the best risk/benefit balance.

Such information could help prevent unnecessary suffering (the use of ineffective SCAMs must inevitably lead to fewer symptoms being optimally treated) as well as reduce the evidently huge waste of money spent on useless SCAMs.

There is hardly a form of therapy under the SCAM umbrella that is not promoted for back pain. None of them is backed by convincing evidence. This might be because back problems are mostly viewed in SCAM as mechanical by nature, and psychological elements are thus often neglected.

This systematic review with network meta-analysis determined the comparative effectiveness and safety of psychological interventions for chronic low back pain. Randomised controlled trials comparing psychological interventions with any comparison intervention in adults with chronic, non-specific low back pain were included.

A total of 97 randomised controlled trials involving 13 136 participants and 17 treatment nodes were included. Inconsistency was detected at short term and mid-term follow-up for physical function, and short term follow-up for pain intensity, and were resolved through sensitivity analyses. For physical function, cognitive behavioural therapy (standardised mean difference 1.01, 95% confidence interval 0.58 to 1.44), and pain education (0.62, 0.08 to 1.17), delivered with physiotherapy care, resulted in clinically important improvements at post-intervention (moderate-quality evidence). The most sustainable effects of treatment for improving physical function were reported with pain education delivered with physiotherapy care, at least until mid-term follow-up (0.63, 0.25 to 1.00; low-quality evidence). No studies investigated the long term effectiveness of pain education delivered with physiotherapy care. For pain intensity, behavioural therapy (1.08, 0.22 to 1.94), cognitive behavioural therapy (0.92, 0.43 to 1.42), and pain education (0.91, 0.37 to 1.45), delivered with physiotherapy care, resulted in clinically important effects at post-intervention (low to moderate-quality evidence). Only behavioural therapy delivered with physiotherapy care maintained clinically important effects on reducing pain intensity until mid-term follow-up (1.01, 0.41 to 1.60; high-quality evidence).

The authors concluded that for people with chronic, non-specific low back pain, psychological interventions are most effective when delivered in conjunction with physiotherapy care (mainly structured exercise). Pain education programmes (low to moderate-quality evidence) and behavioural therapy (low to high-quality evidence) result in the most sustainable effects of treatment; however, uncertainty remains as to their long term effectiveness. Although inconsistency was detected, potential sources were identified and resolved.

The authors’ further comment that their review has identified that pain education, behavioural therapy, and cognitive behavioural therapy are the most effective psychological interventions for people with chronic, non-specific LBP post-intervention when delivered with physiotherapy care. The most sustainable effects of treatment for physical function and fear avoidance are achieved with pain education programmes, and for pain intensity, they are achieved with behavioural therapy. Although their clinical effectiveness diminishes over time, particularly in the long term (≥12 months post-intervention), evidence supports the clinical benefits of combining physiotherapy care with these specific types of psychological interventions at the onset of treatment. The small total sample size at long term follow-up (eg, for physical function, n=6986 at post-intervention v n=2469 for long term follow-up; for pain intensity, n=6963 v n=2272) has resulted in wide confidence intervals at this time point; however, the magnitude and direction of the pooled effects seemed to consistently favour the psychological interventions delivered with physiotherapy care, compared with physiotherapy care alone.

Commenting on their paper, two of the authors, Ferriera and Ho, said they would like to see the guidelines on LBP therapy updated to provide more specific recommendations, the “whole idea” is to inform patients, so they can have conversations with their GP or physiotherapist. Patients should not come to consultations with a passive attitude of just receiving whatever people tell them because unfortunately people still receive the wrong care for chronic back pain,” Ferreira says. “Clinicians prescribe anti-inflammatories or paracetamol. We need to educate patients and clinicians about options and more effective ways of managing pain.”

Is there a lesson here for patients consulting SCAM practitioners for their back pain? Perhaps it is this: it is wise to choose the therapy that has been demonstrated to be effective while having the least potential for harm! And this is not chiropractic or any other form of SCAM. It could, however, well be a combination of physiotherapeutic exercise and psychological therapy.

An article in PULSE entitled ‘ Revolutionising Chiropractic Care for Today’s Healthcare System’ deserves a comment, I think. Here I give you first the article followed by my comments. The references in square brackets refer to the latter and were inserted by me; otherwise, the article is unchanged.

___________________________

This Chiropractic Awareness Week (4th – 10th April), Catherine Quinn, President of the British Chiropractic Association (BCA), is exploring the opportunity and need for a more integrated healthcare eco-system, putting the spotlight on how chiropractors can help alleviate pressures and support improved patient outcomes.

Chiropractic treatment and its role within today’s health system often prompts questions and some debate – what treatments fit under chiropractic care? Is the profession evidence based? How can it support primary health services, with the blend of public and private practice in mind? This Chiropractic Awareness Week, I want to address these questions and share the British Chiropractic Association’s ambition for the future of the profession.

The role of chiropractic today

The need for effective and efficient musculoskeletal (MSK) treatment is clear – in the UK, an estimated 17.8 million people live with a MSK condition, equivalent to approximately 28.9% of the total population.1 Lower back and neck pain specifically are the greatest causes of years lost to disability in the UK, with chronic joint pain or osteoarthritis affecting more than 8.75 million people.2 In addition to this, musculoskeletal conditions also account for 30% of all GP appointments, placing immense pressure on a system which is already under stress.3 The impact of the COVID-19 pandemic is still being felt by these patients and their healthcare professionals alike. Patients with MSK conditions are still having their care impacted by issues such as having clinic appointments cancelled, difficulty in accessing face-to-face care and some unable to continue regular prescribed exercise.

With these numbers and issues in mind, there is a lot of opportunity to more closely integrate chiropractic within health and community services to help alleviate pressures on primary care [1]. This is something we’re really passionate about at the BCA. However, we recognise that there are varying perceptions of chiropractic care – not just from the public but across our health peers too. We want to address this, so every health discipline has a consistent understanding.

First and foremost, chiropractic is a registered primary healthcare profession [2] and a safe form of treatment [3], qualified individuals in this profession are working as fully regulated healthcare professionals with at least four years of Masters level training. In the UK, chiropractors are regulated by law and required to adhere to strict codes of practice [4], in exactly the same ways as dentists and doctors [5]. At the BCA we want to represent the highest quality chiropractic care, which is encapsulated by a patient centred approach, driven by evidence and science [6].

As a patient-first organisation [7], our primary goal is to equip our members to provide the best treatment possible for those who need our care [8]. We truly believe that working collaboratively with other primary care and NHS services is the way to reach this goal [9].

The benefits of collaborative healthcare

As chiropractors, we see huge potential in working more closely with primary care providers and recognise there’s mutual benefits for both parties [10]. Healthcare professionals can tap into chiropractors’ expertise in MSK conditions, leaning on them for support with patient caseloads. Equally, chiropractors can use the experience of working with other healthcare experts to grow as professionals.

At the BCA, our aim is to grow this collaborative approach, working closely with the wider health community to offer patients the best level of care that we can [11]. Looking at primary healthcare services in the UK, we understand the pressures that individual professionals, workforces, and organisations face [12]. We see the large patient rosters and longer waiting times and truly believe that chiropractors can alleviate some of those stresses by treating those with MSK concerns [13].

One way the industry is beginning to work in a more integrated way is through First Contact Practitioners (FCPs) [14]. These are healthcare professionals like chiropractors who provide the first point of contact to GP patients with MSK conditions [15]. We’ve already seen a lot of evidence showing that primary care services using FCPs have been able to improve quality of care [16]. Through this service MSK patients are also seeing much shorter wait times for treatment (as little as 2-3 days), so the benefits speak for themselves for both the patient and GP [17].

By working as part of an integrated care model, with chiropractors, GPs, physiotherapists and other medical professionals, we’re creating a system that provides patients with direct routes to the treatments that they need, with greater choice. Our role within this system is very much to contribute to the health of our country, support primary care workers and reinforce the incredible work of the NHS [18].

Overcoming integrated healthcare challenges

To continue to see the chiropractic sector develop over the coming years, it’s important for us to face some of the challenges currently impacting progress towards a more integrated healthcare service.

One example is that there is a level of uncertainty about where chiropractic sits in the public/private blend. This is something we’re ready to tackle head on by showing exactly how chiropractic care benefits different individuals, whether that’s through reducing pain, improving physical function or increasing mobility [19]. We also need to encourage more awareness amongst both chiropractors and other healthcare providers about how an integrated workforce could benefit medical professionals and patients alike [20]. For example, there’s only two FCP chiropractors to date, and that’s something we’re looking to change [14].

This is the start of a much bigger conversation and, at the BCA, we’ll continue to work on driving peer acceptance, trust and inclusion to demonstrate the value of our place within the healthcare industry [21]. We’re ready to support the wider health community and primary carers, alleviating some of the pressures already facing the NHS; we’re placed in the perfect position as we have the knowledge and experience to provide essential support [22]. My main takeaway from this year’s Chiropractic Awareness Week would be to simply start a conversation with us about how [23].

 

About the British Chiropractic Association:

The BCA is the largest and longest-standing association for chiropractors in the UK. As well as promoting international standards of education and exemplary conduct, the BCA supports chiropractors to progress and develop to fulfil their professional ambitions with honour and integrity, at every step [24]. This Chiropractic Awareness Week, the BCA is raising awareness about the rigour, relevance and evidence driving the profession and the association’s ambition for chiropractic to be more closely embedded within mainstream healthcare [25].

And here are my comments:

  1. Non sequitur = a conclusion or statement that does not logically follow from the previous argument or statement.
  2. A primary healthcare profession is a profession providing primary healthcare which, according to standard definitions, is the provision of health services, including diagnosis and treatment of a health condition, and support in managing long-term healthcare, including chronic conditions like diabetes. Thus chiropractors are not in that category.
  3. This is just wishful thinking. Chiropractic spinal manipulation is not safe!
  4. “Required to adhere to strict codes of practice”. Required yes, but how often do they not comply?
  5. This is not true.
  6. Chiropractic is very far from being “driven by evidence and science”.
  7. Platitude = a remark or statement, especially one with a moral content, that has been used too often to be interesting or thoughtful.
  8. Judging from past experience, the primary goal seems to be to protect chiropractors (see, for instance, here).
  9. Belief is for religion, in healthcare you need evidence. Have you looked at the referral rates of chiropractors to GPs, for instance?
  10. For chiropractors, the benefit is usually measured in £s.
  11. To offer the ” best level of care” you need research and evidence, not politically correct statements.
  12. Platitude = a remark or statement, especially one with a moral content, that has been used too often to be interesting or thoughtful.
  13. Belief is for religion, in healthcare you need evidence.
  14. First Contact Practitioners are “regulated, advanced and autonomous health CARE PROFESSIONALS who are trained to provide expert PATIENT assessment, diagnosis and first-line treatment, self-care advice and, if required, appropriate onward referral to other SERVICES.” I doubt that many chiropractors fulfill these criteria.
  15. Not quite; see above.
  16. “A lot of evidence”? Really? Where is it?
  17.  “The benefits speak for themselves” only if the treatments used are evidence-based.
  18. Platitude = a remark or statement, especially one with a moral content, that has been used too often to be interesting or thoughtful.
  19. Where is the evidence?
  20. Awareness is not needed as much as evidence?
  21. Platitude = a remark or statement, especially one with a moral content, that has been used too often to be interesting or thoughtful.
  22. Platitude = a remark or statement, especially one with a moral content, that has been used too often to be interesting or thoughtful.
  23. Fine, let’s start the conversation: where is your evidence?
  24. Judging from past experience honor and integrity seem rather thin on the ground (see, for instance here).

The article promised to ‘revolutionize chiropractic care and to answer questions like what treatments fit under chiropractic care? Is the profession evidence-based? Sadly, none of this emerged. Instead, we were offered politically correct platitudes, half-truths, and obscurations.

The revolution in chiropractic, it thus seems, is not in sight.

Today, several UK dailies report about a review of osteopathy just published in BMJ-online. The aim of this paper was to summarise the available clinical evidence on the efficacy and safety of osteopathic manipulative treatment (OMT) for different conditions. The authors conducted an overview of systematic reviews (SRs) and meta-analyses (MAs). SRs and MAs of randomised controlled trials evaluating the efficacy and safety of OMT for any condition were included.

The literature searches revealed nine SRs or MAs conducted between 2013 and 2020 with 55 primary trials involving 3740 participants. The SRs covered a wide range of conditions including

  • acute and chronic non-specific low back pain (NSLBP, four SRs),
  • chronic non-specific neck pain (CNSNP, one SR),
  • chronic non-cancer pain (CNCP, one SR),
  • paediatric (one SR),
  • neurological (primary headache, one SR),
  • irritable bowel syndrome (IBS, one SR).

Although with different effect sizes and quality of evidence, MAs reported that OMT is more effective than comparators in reducing pain and improving the functional status in acute/chronic NSLBP, CNSNP and CNCP. Due
to the small sample size, presence of conflicting results and high heterogeneity, questionable evidence existed on OMT efficacy for paediatric conditions, primary headaches and IBS. No adverse events were reported in most SRs. The methodological quality of the included SRs was rated low or critically low.

The authors concluded that based on the currently available SRs and MAs, promising evidence suggests the possible effectiveness of OMT for musculoskeletal disorders. Limited and inconclusive evidence occurs for paediatric conditions, primary headache and IBS. Further well-conducted SRs and MAs are needed to confirm and extend the efficacy and safety of OMT.

This paper raises several questions. Here a just the two that bothered me most:

  1. If the authors had truly wanted to evaluate the SAFETY of OMT (as they state in the abstract), they would have needed to look beyond SRs, MAs or RCTs. We know – and the authors of the overview confirm this – that clinical trials of so-called alternative medicine (SCAM) often fail to mention adverse effects. This means that, in order to obtain a more realistic picture, we need to look at case reports, case series and other observational studies. It also means that the positive message about safety generated here is most likely misleading.
  2. The authors (the lead author is an osteopath) might have noticed that most – if not all – of the positive SRs were published by osteopaths. Their assessments might thus have been less than objective. The authors did not include one of our SRs (because it fell outside their inclusion period). Yet, I do believe that it is one of the few reviews of OMT for musculoskeletal problems that was not done by osteopaths. Therefore, it is worth showing you its abstract here:

The objective of this systematic review was to assess the effectiveness of osteopathy as a treatment option for musculoskeletal pain. Six databases were searched from their inception to August 2010. Only randomized clinical trials (RCTs) were considered if they tested osteopathic manipulation/mobilization against any control intervention or no therapy in human with any musculoskeletal pain in any anatomical location, and if they assessed pain as an outcome measure. The selection of studies, data extraction, and validation were performed independently by two reviewers. Studies of chiropractic manipulations were excluded. Sixteen RCTs met the inclusion criteria. Their methodological quality ranged between 1 and 4 on the Jadad scale (max = 5). Five RCTs suggested that osteopathy compared to various control interventions leads to a significantly stronger reduction of musculoskeletal pain. Eleven RCTs indicated that osteopathy compared to controls generates no change in musculoskeletal pain. Collectively, these data fail to produce compelling evidence for the effectiveness of osteopathy as a treatment of musculoskeletal pain.

It was published 11 years ago. But I have so far not seen compelling evidence that would make me change our conclusion. As I state in the newspapers:

OSTEOPATHY SHOULD BE TAKEN WITH A SIZABLE PINCH OF SALT.

 

 

Spinal cord injury after manual manipulation of the cervical spine is rare and has never been described as resulting from a patient performing a self-manual manipulation on his own cervical spine. This seems to be the first well-documented case of this association.

A healthy 29-year-old man developed Brown-Sequard syndrome immediately after performing a manipulation on his own cervical spine. Brown-Sequard syndrome is characterized by a lesion in the spinal cord which results in weakness or paralysis (hemiparaplegia) on one side of the body and a loss of sensation (hemianesthesia) on the opposite side.

Imaging showed large disc herniations at the levels of C4-C5 and C5-C6 with severe cord compression. The patient underwent emergent surgical decompression. He was discharged to an acute rehabilitation hospital, where he made a full functional recovery by postoperative day 8.

The authors concluded that this case highlights the benefit of swift surgical intervention followed by intensive inpatient rehab. It also serves as a warning for those who perform self-cervical manipulation.

I would add that the case also serves as a warning for those who are considering having cervical manipulation from a chiropractor. Such cases have been reported regularly. Here are three of them:

A spinal epidural hematoma is an extremely rare complication of cervical spine manipulation therapy (CSMT). The authors present the case of an adult woman, otherwise in good health, who developed Brown-Séquard syndrome after CSMT. Decompressive surgery performed within 8 hours after the onset of symptoms allowed for complete recovery of the patient’s preoperative neurological deficit. The unique feature of this case was the magnetic resonance image showing increased signal intensity in the paraspinal musculature consistent with a contusion, which probably formed after SMT. The pertinent literature is also reviewed.

Another case was reported of increased signal in the left hemicord at the C4 level on T2-weighted MR images after chiropractic manipulation, consistent with a contusion. The patient displayed clinical features of Brown-Séquard syndrome, which stabilized with immobilization and steroids. Follow-up imaging showed decreased cord swelling with persistent increased signal. After physical therapy, the patient regained strength on the left side, with residual decreased sensation of pain involving the right arm.

A further case was presented in which such a lesion developed after chiropractic manipulation of the neck. The patient presented with a Brown-Séquard syndrome, which has only rarely been reported in association with cervical epidural hematoma. The correct diagnosis was obtained by computed tomographic scanning. Surgical evacuation of the hematoma was followed by full recovery.

Brown-Séquard syndrome after spinal manipulation seems to be a rare event. Yet, nobody can provide reliable incidence figures because there is no post-marketing surveillance in this area.

The Anglo-European College of Chiropractic (AECC) has been promoting pediatric chiropractic for some time, and I have posted about the subject before  (see, for instance, here). Now the AECC has gone one decisive step further. On the website, the AECC announced an MSc ‘Musculoskeletal Paediatric Health‘:

The MSc Musculoskeletal Paediatric Health degree is designed to develop your knowledge and skills in the safe and competent care of children of all ages. Our part-time, distance-based course blends live online classes with ready to use resources through our virtual learning environment. In addition, you will have the opportunity to observe in the AECC University College clinical services at our Bournemouth campus. The course covers topics in paediatric musculoskeletal practice with specific units on paediatric development, paediatric musculoskeletal examination, paediatric musculoskeletal interventions, and paediatric musculoskeletal management. You will address issues such as risk factors and public health, including breastfeeding, supine sleep in infancy, physical activity in children and conditions affecting the musculoskeletal health of children from birth. The paediatric specific topics are completed by other optional units such as professional development, evidence-based practice, and leadership and inter-professional collaboration. In the dissertation unit you will conduct a study relevant to musculoskeletal paediatric health.

Your learning will happen through a mix of live and recorded lectures, access to online reading materials, and access to the literature through our learning services. You will also engage with the contents taught through guided activities with your peers and staff. Clinical paediatric experience is recommended to fully engage with the course. For students with limited access to a suitable clinical environment to support their studies, or for student who wants to add to their clinical experience, we are able to offer a limited number of opportunities to observe and work alongside our clinical educators within the AECC University College clinical services. Assessments are tailor made to each unit and may include a variety of methods such as critical reviews, reflective accounts, portfolios and in the last year a research dissertation.

___________________________

The AECC emphasizes its commitment to being a leading higher education institution in healthcare disciplines, nationally and internationally recognised for quality and excellence. Therefore, it seems only fair to have another look at the science behind pediatric chiropractic. Specifically, is there any good science to show that would justify a Master of Science in ‘Musculoskeletal Paediatric Health’?

So, let’s have a look and see whether there are any good review articles supporting such a degree. Here is what I found with several Medline searches (date of the review on chiropractic for any pediatric conditions, followed by its conclusion + link [so that the reader can look up the evidence]):

2008

I am unable to find convincing evidence for any of the above-named conditions. 

2009

Previous research has shown that professional chiropractic organisations ‘make claims for the clinical art of chiropractic that are not currently available scientific evidence…’. The claim to effectively treat otitis seems to
be one of them. It is time now, I think, that chiropractors either produce the evidence or abandon the claim.

2009

The … evidence is neither complete nor, in my view, “substantial.”

2010

Although the major reason for pediatric patients to attend a chiropractor is spinal pain, no adequate studies have been performed in this area. It is time for the chiropractic profession to take responsibility and systematically investigate the efficiency of joint manipulation of problems relating to the developing musculoskeletal system.

2018

Some small benefits were found, but whether these are meaningful to parents remains unclear as does the mechanisms of action. Manual therapy appears relatively safe.

What seems to emerge is rather disappointing:

  1. There are no really new reviews.
  2. Most of the existing reviews are not on musculoskeletal conditions.
  3. All of the reviews cast considerable doubt on the notion that chiropractors should go anywhere near children.

But perhaps I was too ambitious. Perhaps there are some new rigorous clinical trials of chiropractic for musculoskeletal conditions. A few further searches found this (again year and conclusion):

2019

We found that children with long duration of spinal pain or co-occurring musculoskeletal pain prior to inclusion as well as low quality of life at baseline tended to benefit from manipulative therapy over non-manipulative therapy, whereas the opposite was seen for children reporting high intensity of pain. However, most results were statistically insignificant.

2018

Adding manipulative therapy to other conservative care in school children with spinal pain did not result in fewer recurrent episodes. The choice of treatment-if any-for spinal pain in children therefore relies on personal preferences, and could include conservative care with and without manipulative therapy. Participants in this trial may differ from a normal care-seeking population.

I might have missed one or two trials because I only conducted rather ‘rough and ready’ searches, but even if I did: would this amount to convincing evidence? Would it be good science?

No! and No!

So, why does the AECC offer a Master of Science in ‘Musculoskeletal Paediatric Health’?

Search me!

It wouldn’t have something to do with the notion that it is good for business?

Or perhaps they just want to give science a bad name?

Anyone who has been following this blog will have noticed that we have our very own ‘resident chiro’ who comments every single time I post about spinal manipulation/chiropractic/back pain. He uses (mostly?) the pseudonym ‘DC’. Recently, DC explained why he is such an avid poster of comments:

” I read and occasionally comment on this blog for two main reasons. 1. In my opinion Ernst doesn’t do a balance reporting on the papers his shares regarding spinal manipulation and chiropractic. Thus, I offer additional insight, a more balanced perspective for the readers. 2. There are a couple of skeptics who occasionally post that do a good job of analyzing papers or topics and they do so in a respectful manner. I enjoy reading their comments. I will add a third. 3. Ernst, from what I can tell, doesn’t censor people just because they have a different view.”

So, DC aims at offering additional insights and a more balanced perspective. That would certainly be laudable and welcome. Yet, over the years, I have gained a somewhat different impression. Almost invariably, my posts on the named subjects cast doubt on the notion that chiropractic generates more good than harm. This, of course, cannot be to the liking of chiropractors, who therefore try to undermine me and my arguments. In a way, that is fair enough.

DC, however, seems to have long pursued a very specific and slightly different strategy. He systematically attempts to distract from the evidence and arguments I present. He does that by throwing in the odd red herring or by deviating from the subject in some other way. Thus he hopes, I assume, to distract from the point that chiropractic fails to generate more good than harm. In other words, DC is a tireless (and often tiresome) fighter for the chiropractic cause and reputation.

To check whether my impression is correct, I went through the last 10 blogs on spinal manipulation/ chiropractic/ back pain. Here are my findings (first the title of and link to the blog in question, followed by one of DC’s originals distractions)

Chiropractic: “a safe form of treatment”? (edzardernst.com)

correct!
real doctors treat really sick patients

So the probability of an AE increases based upon how sick a patient is? Is there research that supports that?

Malpractice Litigation Involving Chiropractic Spinal Manipulation (edzardernst.com)

It would be interesting to know more about these 38 cases that weren’t included since that’s almost half of the 86 cases. What percentage of those cases involved SMT by a non chiropractor?

“Query of the VerdictSearch online legal database for “chiropractor” OR “chiropractic” OR “spinal manipulation” within the 22,566 listed cases classified as “medical malpractice” yielded 86 cases. Of these, 48 cases met the inclusion criteria by featuring a chiropractic practitioner as the primary defendant.”

Acute Subdural Hemorrhage Following Cervical Chiropractic Manipulation (edzardernst.com)

sigh, my use of the word require was pointing out that different problems require different solutions.

You confuse a lack of concern with my critical analysis of what some use as evidence of serious harm.

I have only used one other identifier on this blog. Some objected to my use of the word Dr in that identifier so I changed it to DC as it wasn’t worth my time to argue with them (which of course DC still refers to Doctor but it seemed to appease them).

In healthcare and particularly in manual therapy we look at increasing comfort and function because most come to us because…wait for it…a loss of comfort and function.

Yes, there is the potential to cause harm, I have never said otherwise. Most case reports suggest that serious harm is due to an improper history and exam (although other reasons may exist such as improper technique). Thus, most cases appear to be preventable with a proper history, exam and technique. That, is a different problem that, yes, requires a different solution.

So yes, spinal manipulation isn’t “required” anymore than physical therapy, NSAIDs, etc for most cases. The question is: does the intervention increase comfort and function over doing nothing and is that justified due the potential risk of harm….benefit vs risk.

Now, i shall excuse my self to prepare for a research presentation that deals with a possible new contraindication to cSMT (because I have a lack of concern, right?)

The best approach is to consider the totality of the available evidence. By doing this, one cannot exclude the possibility that NSAIDs and opioids cause serious adverse effects. If that is so, we must abide by the precautionary principle which tells us to use other treatments that seem safer and at least as effective.

So based upon the totality of the available evidence, which is safer and at least as effective: cervical spinal manipulation vs NSAIDs/opioids?

No 9

Chiropractic spinal manipulation is not safe! (edzardernst.com)

getting the patient to sign something describing the risks. This is apparently something chiropractors don’t do before a neck manipulation.

Apparently?

Vertebral artery dissection in a pregnant woman after cervical spine manipulation (edzardernst.com)

Most case reports fail on one of two criteria, sometimes both.

1. No clear record of why the patient sought chiropractic care (symptoms that may indicate a VAD in progress or not)

2. Eliminating any other possible causes of the VAD especially in the week prior to SMT.

I would have to search but I recall a case report of a woman presenting for maintenance care (no head or neck symptoms at the time) and after cSMT was dx with a VAD. Asymptomatic VADs are very rare thus there is a high probability that cSMT induced the VAD in that case, IMO.

Although not published I had a dialogue with a MD where a patient underwent a MRI, had cSMT the next day and developed new symptoms thus another MRI was shortly done and was dx with a VAD. I encouraged her to publish the case but apparently she did not.

There was a paper published that looked at the quality of these case reports, most are poor.

I might be mistaken but DC systematically tries to distract from the fact that chiropractic does not generate more good than harm and that there is a continuous flow of evidence suggesting it does, in fact, the exact opposite. He (I presume he is male) might not even do this consciously in which case it would suggest to me that he is full of quasi-religious zeal and unable to think critically about his own profession and creeds.

Reviewing the material above, I also realized that, by engaging with DC (and other zealots of this type), it is I who often gives him the opportunity to play his game. Therefore, I will from now on try harder to stick to my own rules that say:

  • Comments must be on-topic.
  • I will not post comments which are overtly nonsensical.
  • I will not normally enter into discussions with people who do not disclose their full identity.

 

Today is the start of chiropractic awareness week 2022. On this occasion the BCA states most categorically: First and foremost, chiropractic is a statutorily regulated healthcare profession, supported by evidence, which offers a safe form of treatment for patients with a range of conditions.  Here I am tempted to cite my friend Simon Singh:

THEY HAPPILY PROMOTE BOGUS TREATMENTS

I am, of course, particularly impressed by the BCA’s assurance of safety. In my view, the safety issue needs to be addressed more urgently than any other in the realm of chiropractic. So, to make a meaningful contribution to the current chiropractic awareness week, I conducted a few Medline searches to identify all publications of 2022 on chiropractic/spinal manipulation risks.

This is what I found:

paper No 1

Objective: Patients can be at risk of carotid artery dissection and ischemic stroke after cervical chiropractic manipulation. However, such risks are rarely reported and raising awareness can increase the safety of chiropractic manipulations.

Case report: We present two middle-aged patients with carotid artery dissection leading to ischemic stroke after receiving chiropractic manipulation in Foshan, Guangdong Province, China. Both patients had new-onset pain in their necks after receiving chiropractic manipulations. Excess physical force during chiropractic manipulation may present a risk to patients. Patient was administered with recombinant tissue plasminogen activator after radiological diagnoses. They were prescribed 100 mg and clopidogrel 75 mg daily for 3 months as dual antiplatelet therapy. There were no complications over the follow-up period.

Conclusion: These cases suggest that dissection of the carotid artery can occur as the result of chiropractic manipulations. Patients should be diagnosed and treated early to achieve positive outcomes. The safety of chiropractic manipulations should be increased by raising awareness about the potential risks.

paper No 2

Spontaneous intracranial hypotension (SIH) still remains an underdiagnosed etiology of new-onset headache. Important risk factors include chiropractic manipulation (CM). We present a case of a 36-year-old Filipino woman who presented with severe bifrontal and postural headache associated with dizziness, vomiting, and doubling of vision. A cranial computed tomography scan was done which showed an acute subdural hematoma (SDH) at the interhemispheric area. Pain medications were given which afforded minimal relief. On history, the headaches occurred 2 weeks after cervical CM. Cranial and cervical magnetic resonance imaging revealed findings supportive of intracranial hypotension and neck trauma, respectively. The patient improved with conservative management. We found 12 articles on SIH and CM after a systematic review of literature. Eleven patients (90.9%) initially presented with orthostatic headache. Eight patients (66.7%) were initially treated conservatively but only 5 (62.5%) had complete recovery. Recovery was achieved within 14 days from start of supportive therapy. Among the 3 patients who failed conservative treatment, 2 underwent non-directed epidural blood patch and one required neurosurgical intervention. This report highlights that a thorough history is warranted in patients with new onset headache. A history of CM must be actively sought. The limited evidence from the case reports showed that patients with SIH and SDH but with normal neurologic examination and minor spinal pathology can be managed conservatively for less than 2 weeks. This review showed that conservative treatment in a closely monitored environment may be an appropriate first line treatment.

paper No 3

Introduction: Cranio-cervical artery dissection (CeAD) is a common cause of cerebrovascular events in young subjects with no clear treatment strategy established. We evaluated the incidence of major adverse cardiovascular events (MACE) in CeAD patients treated with and without stent placement.

Methods: COMParative effectiveness of treatment options in cervical Artery diSSection (COMPASS) is a single high-volume center observational, retrospective longitudinal registry that enrolled consecutive CeAD patients over a 2-year period. Patients were ≥ 18 years of age with confirmed extra- or intracranial CeAD on imaging. Enrolled participants were followed for 1 year evaluating MACE as the primary endpoint.

Results: One-hundred ten patients were enrolled (age 53 ± 15.9, 56% Caucasian, and 50% male, BMI 28.9 ± 9.2). Grade I, II, III, and IV blunt vascular injury was noted in 16%, 33%, 19%, and 32%, respectively. Predisposing factors were noted in the majority (78%), including sneezing, carrying heavy load, chiropractic manipulation. Stent was placed in 10 (10%) subjects (extracranial carotid n = 9; intracranial carotid n = 1; extracranial vertebral n = 1) at the physician’s discretion along with medical management. Reasons for stent placement were early development of high-grade stenosis or expanding pseudoaneurysm. Stented patients experienced no procedural or in-hospital complications and no MACE between discharge and 1 year follow up. CeAD patients treated with medical management only had 14% MACE at 1 year.

Conclusion: In this single high-volume center cohort of CeAD patients, stenting was found to be beneficial, particularly with development of high-grade stenosis or expanding pseudoaneurysm. These results warrant confirmation by a randomized clinical trial.

paper No 4

Background: Manipulation and mobilisation for low back pain are presented in an evidence-based manner with regard to mechanisms of action, indications, efficacy, cost-effectiveness ratio, user criteria and adverse effects. Terms such as non-specific or specific are replaced by the introduction of “entities” related to possible different low back pain forms.

Efficacy: MM is effective for acute and chronic low back pain in terms of pain relief, recovery of function and relapse prevention. It is equally effective but less risky compared to other recommended therapies. MM can be used alone in acute cases and not only in the case of chronic low back pain where it is always and necessarily part of a multimodal therapy programme, especially in combination with activating measures. The users of MM should exclusively be physician specialists trained according to the criteria of the German Medical Association (Bundesärztekammer) with an additional competence in manual medicine or appropriately trained certified therapists. The application of MM follows all rules of Good Clinical Practice.

Adverse effects: Significant adverse effects of MM for low back pain are reported in the international literature with a frequency of 1 per 50,000 to 1 per 3.7 million applications, i.e. MM for low back pain is practically risk-free and safe if performed according to the rules of the European Training Requirements of the UEMS.

paper No 5

Studies have reported that mild adverse events (AEs) are common after manual therapy and that there is a risk of serious injury. We aimed to assess the safety of Chuna manipulation therapy (CMT), a traditional manual Korean therapy, by analysing AEs in patients who underwent this treatment. Patients who received at least one session of CMT between December 2009 and March 2019 at 14 Korean medicine hospitals were included. Electronic patient charts and internal audit data obtained from situation report logs were retrospectively analysed. All data were reviewed by two researchers. The inter-rater agreement was assessed using the Cohen’s kappa coefficient, and reliability analysis among hospitals was assessed using Cronbach’s Alpha coefficient. In total, 2,682,258 CMT procedures were performed in 289,953 patients during the study period. There were 50 AEs, including worsened pain (n = 29), rib fracture (n = 11), falls during treatment (n = 6), chest pain (n = 2), dizziness (n = 1), and unpleasant feeling (n = 1). The incidence of mild to moderate AEs was 1.83 (95% confidence interval [CI] 1.36-2.39) per 100,000 treatment sessions, and that of severe AEs was 0.04 (95% CI 0.00-0.16) per 100,000 treatment sessions. Thus, AEs of any level of severity were very rare after CMT. Moreover, there were no instances of carotid artery dissection or spinal cord injury, which are the most severe AEs associated with manual therapy in other countries.

This is not too bad after all!

Five papers are clearly better than nothing.

What conclusions might be drawn from my mini-review?

I think it might be safe to say:

  1. There is not much but at least some research going on in this area.
  2. The risks of chiropractic/spinal manipulation are real and are being recognized.
  3. BUT NOT BY CHIROPRACTORS! The most remarkable feature of the 5 papers, I think, is that none originates from a chiropractic team.

Thus, allow me to make a suggestion to chiropractors worldwide: Instead of continuing with HAPPILY PROMOTING BOGUS TREATMENTS, what about using the ‘chiropractic awareness week’ to raise awareness of the urgent necessity to research the safety of your treatments?

This paper is an evaluation of the relationship between chiropractic spinal manipulation and medical malpractice. The legal database VerdictSearch was queried using the terms “chiropractor” OR “spinal manipulation” under the classification of “Medical Malpractice” between 1988 and 2018. Cases with chiropractors as defendants were identified. Relevant medicolegal characteristics were obtained, including legal outcome (plaintiff/defense verdict, settlement), payment amount, nature of plaintiff claim, and type and location of the alleged injury.

Forty-eight cases involving chiropractic management in the US were reported. Of these, 93.8% (n = 45) featured allegations involving spinal manipulation. The defense (practitioner) was victorious in 70.8% (n = 34) of cases, with a plaintiff (patient) victory in 20.8% (n = 10) (mean payment $658,487 ± $697,045) and settlement in 8.3% (n = 4) (mean payment $596,667 ± $402,534).

Over-aggressive manipulation was the most frequent allegation (33.3%; 16 cases). A majority of cases alleged neurological injury of the spine as the reason for litigation (66.7%, 32 cases) with 87.5% (28/32) requiring surgery. C5-C6 disc herniation was the most frequently alleged injury (32.4%, 11/34, 83.3% requiring surgery) followed by C6-C7 herniation (26.5%, 9/34, 88.9% requiring surgery). Claims also alleged 7 cases of stroke (14.6%) and 2 rib fractures (4.2%) from manipulation therapy.

The authors concluded that litigation claims following chiropractic care predominately alleged neurological injury with consequent surgical management. Plaintiffs primarily alleged overaggressive treatment, though a majority of trials ended in defensive verdicts. Ongoing analysis of malpractice provides a unique lens through which to view this complicated topic.

The fact that the majority of trials ended in defensive verdicts does not surprise me. I once served as an expert witness in a trial against a UK chiropractor. Therefore, I know how difficult it is to demonstrate that the chiropractic intervention – and not anything else – caused the problem. Even cases that seem medically clear-cut, often allow reasonable doubt vis a vis the law.

Apologists will be quick and keen to point out that, in the US, there are many more successful cases brought against real doctors (healthcare professionals who have studied medicine). They are, of course, correct. But, at the same time, they miss the point. Real doctors treat real diseases where the outcomes are sadly often not as hoped. Litigation is then common, particularly in a litigious society like the US. Chiropractors predominantly treat symptoms like back troubles that are essentially benign. To create a fair comparison of litigations against doctors and chiros, one would therefore need to account for the type and severity of the conditions. Such a comparison has – to the best of my knowledge – not been done.

What has been done, however – and I did previously report about it – are comparisons between chiros, osteos, and physios (which seems to be a more level playing field). They show that complaints against chiros top the bill.

No 10-year follow-up study of so-called alternative medicine (SCAM) for lumbar intervertebral disc herniation (LDH) has so far been published. Therefore, the authors of this paper performed a prospective 10-year follow-up study on the integrated treatment of LDH in Korea.

One hundred and fifty patients from the baseline study, who initially met the LDH diagnostic criteria with a chief complaint of radiating pain and received integrated treatment, were recruited for this follow-up study. The 10-year follow-up was conducted from February 2018 to March 2018 on pain, disability, satisfaction, quality of life, and changes in a herniated disc, muscles, and fat through magnetic resonance imaging.

Sixty-five patients were included in this follow-up study. Visual analogue scale score for lower back pain and radiating leg pain were maintained at a significantly lower level than the baseline level. Significant improvements in Oswestry disability index and quality of life were consistently present. MRI confirmed that disc herniation size was reduced over the 10-year follow-up. In total, 95.38% of the patients were either “satisfied” or “extremely satisfied” with the treatment outcomes and 89.23% of the patients claimed their condition “improved” or “highly improved” at the 10-year follow-up.

The authors concluded that the reduced pain and improved disability was maintained over 10 years in patients with LDH who were treated with nonsurgical Korean medical treatment 10 years ago. Nonsurgical traditional Korean medical treatment for LDH produced beneficial long-term effects, but future large-scale randomized controlled trials for LDH are needed.

This study and its conclusion beg several questions:

WHAT DID THE SCAM CONSIST OF?

The answer is not  provided in the paper; instead, the authors refer to 3 previous articles where they claim to have published the treatment schedule:

I could only access the BMJ Open article, and it tells is this:

The treatment package included herbal medicine, acupuncture, bee venom pharmacopuncture and Chuna therapy (Korean spinal manipulation). Treatment was conducted once a week for 24 weeks, except herbal medication which was taken twice daily for 24 weeks; (1) Acupuncture: frequently used acupoints (BL23, BL24, BL25, BL31, BL32, BL33, BL34, BL40, BL60, GB30, GV3 and GV4)10 ,11 and the site of pain were selected and the needles were left in situ for 20 min. Sterilised disposable needles (stainless steel, 0.30×40 mm, Dong Bang Acupuncture Co., Korea) were used; (2) Chuna therapy12 ,13: Chuna is a Korean spinal manipulation that includes high-velocity, low-amplitude thrusts to spinal joints slightly beyond the passive range of motion for spinal mobilisation, and manual force to joints within the passive range; (3) Bee venom pharmacopuncture14: 0.5–1 cc of diluted bee venom solution (saline: bee venom ratio, 1000:1) was injected into 4–5 acupoints around the lumbar spine area to a total amount of 1 cc using disposable injection needles (CPL, 1 cc, 26G×1.5 syringe, Shinchang medical Co., Korea); (4) Herbal medicine was taken twice a day in dry powder (2 g) and water extracted decoction form (120 mL) (Ostericum koreanum, Eucommia ulmoides, Acanthopanax sessiliflorus, Achyranthes bidentata, Psoralea corylifolia, Peucedanum japonicum, Cibotium barometz, Lycium chinense, Boschniakia rossica, Cuscuta chinensis and Atractylodes japonica). These herbs were selected from herbs frequently prescribed for LBP (or nerve root pain) treatment in Korean medicine and traditional Chinese medicine,15 and the prescription was further developed through clinical practice at Jaseng Hospital of Korean Medicine.9 In addition, recent investigations report that compounds of C. barometz inhibit osteoclast formation in vitro16 and A. japonica extracts protect osteoblast cells from oxidative stress.17 E. ulmoides has been reported to have osteoclast inhibitive,18 osteoblast-like cell proliferative and bone mineral density enhancing effects.19 Patients were given instructions by their physician at treatment sessions to remain active and continue with daily activities while not aggravating pre-existing symptoms. Also, ample information about the favourable prognosis and encouragement for non-surgical treatment was given.

The traditional Korean spinal manipulations used (‘Chuna therapy’ – the references provided for it do NOT refer to this specific way of manipulation) seemed interesting, I thought. Here is an explanation from an unrelated paper: Image result for chuna therapy

Chuna, which is a traditional manual therapy practiced by Korean medicine doctors, has been applied to various diseases in Korea. Chuna manual therapy (CMT) is a technique that uses the hand, other parts of the doctor’s body or other supplementary devices such as a table to restore the normal function and structure of pathological somatic tissues by mobilization and manipulation. CMT includes various techniques such as thrust, mobilization, distraction of the spine and joints, and soft tissue release. These techniques were developed by combining aspects of Chinese Tuina, chiropratic, and osteopathic medicine.[] It has been actively growing in Korea, academically and clinically, since the establishment of the Chuna Society (the Korean Society of Chuna Manual Medicine for Spine and Nerves, KSCMM) in 1991.[] Recently, Chuna has had its effects nationally recognized and was included in the Korean national health insurance in March 2019.[]

This almost answers the other questions I had. Almost, but not quite. Here are two more:

  • The authors conclude that the SCAM produced beneficial long-term effects. But isn’t it much more likely that the outcomes their uncontrolled observations describe are purely or at least mostly a reflection of the natural history of lumbar disc herniation?
  • If I remember correctly, I learned a long time ago in medical school that spinal manipulation is contraindicated in lumbar disc herniation. If that is so, the results might have been better, if the patients of this study had not received any SCAM at all. In other words, are the results perhaps due to firstly the natural history of the condition and secondly to the detrimental effects of the SCAM the investigators applied?

If I am correct, this would then be the 4th article reporting the findings of a SCAM intervention that aggravated lumbar disc herniation.

 

 

PS

I know that this is a mere hypothesis but it is at least as plausible as the conclusion drawn by the authors.
