Some people seem to believe that the field of alternative medicine resembles a quaint little cottage industry where money hardly matters. A new analysis shows how far from the truth this impression is.
In the 2007 US National Health Interview Survey, use of complementary health approaches, reasons for this use, and associated out of pocket (OOP) costs were captured in a nationally representative sample of 5,467 US adults. Ordinary least square regression models that controlled for co-morbid conditions were used to estimate aggregate and per person OOP costs associated with 14 painful health conditions.
The analyses suggest that individuals using complementary approaches spent a total of $14.9 billion OOP on these approaches to manage three painful conditions: arthritis, back pain and fibromyalgia. Around 7.5 billion of that total was spent on consulting practitioners such as chiropractors and acupuncturists. Total OOP expenditures seen in those using complementary approaches for their back pain ($8.7 billion) far outstripped that of any other condition, with the majority of these costs ($4.7 billion) resulting from visits to complementary providers. Annual condition-specific per-person OOP costs varied from a low of $568 for regular headaches, to a high of $895 for fibromyalgia. The total expenditure on complementary medicine was comparable to that on conventional care.
The authors concluded that adults in the United States spent $14.9 billion OOP on complementary health approaches (e.g., acupuncture, chiropractic, herbal medicines) to manage painful conditions including back pain ($8.7 billion). This back pain estimate is almost 1/3rd of total conventional healthcare expenditures for back pain ($30.4 billion) and 2/3rds higher than conventional OOP expenditures ($5.1 billion).
These are truly eye-watering sums. The obvious question is: IS THIS MONEY WELL-SPENT?
The short answer, I fear, is NO!
The alternative therapies in question are not based on compelling evidence in the management of these painful conditions. Some are clearly not better than placebo, and others are apparently supported by some research but its quality is hardly good enough to rely upon.
This level expenditure is both impressive and worrying. It highlights an enormous waste of resources, alerts us to an urgent need for truly rigorous research, and demonstrates how high the stakes really are.
Regular readers of this blog will be aware of the many bogus claims made by chiropractors. One claim, however, namely the one postulating chiropractors can effectively treat low back pain with spinal manipulation, is rarely viewed as being bogus. Chiropractors are usually able to produce evidence that does suggest the claim to be true, and therefore even most critics of chiropractic back off on this particular issue.
But is the claim really true?
A recent trial might provide the answer.
The purpose of this study was to compare the effectiveness of chiropractic spinal manipulative therapy (cSMT) to a sham intervention on pain (Visual Analogue Scale, SF-36 pain subscale), disability (Oswestry Disability Index), and physical function (SF-36 subscale, Timed Up and Go) by performing a randomized placebo-controlled trial at 2 Veteran Affairs Clinics.
Older veterans (≥ 65 years of age) who were naive to chiropractic were recruited. A total of 136 who suffered from chronic low back pain (LBP) were included in the study – with 69 being randomly assigned to cSMT and 67 to the sham intervention. Patients were treated twice per week for 4 weeks. The outcomes were assessed at baseline, 5, and 12 weeks post baseline.
Both groups demonstrated significant decrease in pain and disability at 5 and 12 weeks. At 12 weeks, there was no significant difference in pain and a statistically significant decline in disability scores in the cSMT group when compared to the control group. There were no significant differences in adverse events between the groups.
The authors concluded that cSMT did not result in greater improvement in pain when compared to our sham intervention; however, cSMT did demonstrate a slightly greater improvement in disability at 12 weeks. The fact that patients in both groups showed improvements suggests the presence of a nonspecific therapeutic effect.
Hold on, I hear you say, this does not mean that cSMT is a placebo in the treatment of LBP! There are other studies that yield positive results. Let’s not cherry-pick our evidence!
Absolutely correct! To avoid cherry-picking, lets see what the current Cochrane review tells us about cSMT and chronic LBP. Here is the conclusion of this review based on 26 RCTs: High quality evidence suggests that there is no clinically relevant difference between SMT and other interventions for reducing pain and improving function in patients with chronic low-back pain.
The purpose of this study was to evaluate the impact of early and guideline adherent physical therapy for low back pain on utilization and costs within the Military Health System (MHS).
Patients presenting to a primary care setting with a new complaint of LBP from January 1, 2007 to December 31, 2009 were identified from the MHS Management Analysis and Reporting Tool. Descriptive statistics, utilization, and costs were examined on the basis of timing of referral to physical therapy and adherence to practice guidelines over a 2-year period. Utilization outcomes (advanced imaging, lumbar injections or surgery, and opioid use) were compared using adjusted odds ratios with 99% confidence intervals. Total LBP-related health care costs over the 2-year follow-up were compared using linear regression models.
753,450 eligible patients with a primary care visit for LBP between 18-60 years of age were considered. Physical therapy was utilized by 16.3% (n = 122,723) of patients, with 24.0% (n = 17,175) of those receiving early physical therapy that was adherent to recommendations for active treatment. Early referral to guideline adherent physical therapy was associated with significantly lower utilization for all outcomes and 60% lower total LBP-related costs.
The authors concluded that the potential for cost savings in the MHS from early guideline adherent physical therapy may be substantial. These results also extend the findings from similar studies in civilian settings by demonstrating an association between early guideline adherent care and utilization and costs in a single payer health system. Future research is necessary to examine which patients with LBP benefit early physical therapy and determine strategies for providing early guideline adherent care.
These are certainly interesting data. Because LBP is such a common condition, it costs us all dearly. Measures to reduce this burden in suffering and expense are urgently needed. The question is whether early referral to a physiotherapist is such a measure. The present data show that this is possible but they do not prove it.
I applaud the authors for realising this point and discussing it at length: The results of this study should be examined in light of the following limitations. Given the favorable natural history of LBP, many patients improve regardless of treatment. Those referred to physical therapy early are also more likely to have a shorter duration of pain, thus the potential for selection bias to have influenced these results. We accounted for a number of co-morbidities available in the data set and excluded patients with prior visits for LBP to mitigate against this possibility. However, the retrospective observational design of this study imposes limitations on extending the associations we observed to causation. Although we attempted to exclude patients with a specific spinal pathology, it is possible that a few patients may have been inadvertently included in the data set, in which case advanced imaging may be indicated. Additionally, although our results support that early physical therapy which adheres to practice guidelines may be less resource intense, we cannot conclude without patient-centered clinical outcomes (i.e., pain, function, disability, satisfaction, etc.) that the care was more cost effective. Further, it may be that the standard we used to judge adherence to practice guidelines (CPT codes) was not sufficiently sensitive to determine whether care is consistent with clinical practice guidelines. We also did not account for indirect or out-of-pocket costs for treatments such as complementary care, which is common for LBP. However, it is likely that the observed effects on total costs would have been even larger had these costs been considered.
I was originally alerted to this paper through a tweet claiming that these results demonstrate that chiropractic has an important role in LBP. However, the study does not even imply such a conclusion. It is, of course, true that many chiropractors use physical therapies. But they do not have the same training as physiotherapists and they tend to use spinal manipulations far more frequently. Virtually every LBP-patient consulting a chiropractor would be treated with spinal manipulations. As this approach is neither based on sound evidence nor free of risks, the conclusion, in my view, cannot be to see chiropractors for LBP; it must be to consult a physiotherapist.
Iyengar Yoga, named after and developed by B. K. S. Iyengar, is a form of Hatha Yoga that has an emphasis on detail, precision and alignment in the performance of posture (asana) and breath control (pranayama). The development of strength, mobility and stability is gained through the asanas.
B.K.S. Iyengar has systematised over 200 classical yoga poses and 14 different types of Pranayama (with variations of many of them) ranging from the basic to advanced. This helps ensure that students progress gradually by moving from simple poses to more complex ones and develop their mind, body and spirit step by step.
Iyengar Yoga often makes use of props, such as belts, blocks, and blankets, as aids in performing asanas (postures). The props enable students to perform the asanas correctly, minimising the risk of injury or strain, and making the postures accessible to both young and old.
Sounds interesting? But does it work?
The objective of this recent systematic review was to conduct a systematic review of the existing research on Iyengar yoga for relieving back and neck pain. The authors conducted extensive literature searches and found 6 RCTs that met the inclusion criteria.
The difference between the groups on the post-intervention pain or functional disability intensity assessment was, in all 6 studies, favouring the yoga group, which projected a decrease in back and neck pain.
The authors concluded that Iyengar yoga is an effective means for both back and neck pain in comparison to control groups. This systematic review found strong evidence for short-term effectiveness, but little evidence for long-term effectiveness of yoga for chronic spine pain in the patient-centered outcomes.
So, if we can trust this evidence (I would not call the evidence ‘strong), we have yet another treatment that might be effective for acute back and neck pain. The trouble, I fear, is not that we have too few such treatments, the trouble seems to be that we have too many of them. They all seem similarly effective, and I cannot help but wonder whether, in fact, they are all similarly ineffective.
Regardless of the answer to this troubling question, I feel the need to re-state what I have written many times before: FOR A CONDITION WITH A MULTITUDE OF ALLEGEDLY EFFECTIVE THERAPIES, IT MIGHT BE BEST TO CHOSE THE ONE THAT IS SAFEST AND CHEAPEST.
On 1/12/2014 I published a post in which I offered to give lectures to students of alternative medicine:
Getting good and experienced lecturers for courses is not easy. Having someone who has done more research than most working in the field and who is internationally known, might therefore be a thrill for students and an image-boosting experience of colleges. In the true Christmas spirit, I am today making the offer of being of assistance to the many struggling educational institutions of alternative medicine .
A few days ago, I tweeted about my willingness to give free lectures to homeopathic colleges (so far without response). Having thought about it a bit, I would now like to extend this offer. I would be happy to give a free lecture to the students of any educational institution of alternative medicine.
I did not think that this would create much interest – and I was right: only the ANGLO-EUROPEAN COLLEGE OF CHIROPRACTIC has so far hoisted me on my own petard and, after some discussion (see comment section of the original post) hosted me for a lecture. Several people seem keen on knowing how this went; so here is a brief report.
I was received, on 14/1/2015, with the utmost kindness by my host David Newell. We has a coffee and a chat and then it was time to start the lecture. The hall was packed with ~150 students and the same number was listening in a second lecture hall to which my talk was being transmitted.
We had agreed on the title CHIROPRACTIC: FALLACIES AND FACTS. So, after telling the audience about my professional background, I elaborated on 7 fallacies:
- Appeal to tradition
- Appeal to authority
- Appeal to popularity
- Subluxation exists
- Spinal manipulation is effective
- Spinal manipulation is safe
- Ad hominem attack
Numbers 3, 5 and 6 were dealt with in more detail than the rest. The organisers had asked me to finish by elaborating on what I perceive as the future challenges of chiropractic; so I did:
- Stop happily promoting bogus treatments
- Denounce obsolete concepts like ‘subluxation’
- Clarify differences between chiros, osteos and physios
- Start a culture of critical thinking
- Take action against charlatans in your ranks
- Stop attacking everyone who voices criticism
I ended by pointing out that the biggest challenge, in my view, was to “demonstrate with rigorous science which chiropractic treatments demonstrably generate more good than harm for which condition”.
We had agreed that my lecture would be followed by half an hour of discussion; this period turned out to be lively and had to be extended to a full hour. Most questions initially came from the tutors rather than the students, and most were polite – I had expected much more aggression.
In his email thanking me for coming to Bournemouth, David Newell wrote about the event: The general feedback from staff and students was one of relief that you possessed only one head, :-). I hope you may have felt the same about us. You came over as someone who had strong views, a fair amount of which we disagreed with, but that presented them in a calm, informative and courteous manner as we did in listening and discussing issues after your talk. I think everyone enjoyed the questions and debate and felt that some of the points you made were indeed fair critique of what the profession may need to do, to secure a more inclusive role in the health care arena.
My own impression of the day is that some of my messages were not really understood, that some of the questions, including some from the tutors, seemed like coming from a different planet, and that people were more out to teach me than to learn from my talk. One overall impression that I took home from that day is that, even in this college which prides itself of being open to scientific evidence and unimpressed by chiropractic fundamentalism, students are strangely different from other health care professionals. The most tangible aspect of this is the openly hostile attitude against drug therapies voiced during the discussion by some students.
The question I always ask myself after having invested a lot of time in preparing and delivering a lecture is: WAS IT WORTH IT? In the case of this lecture, I think the answer is YES. With 300 students present, I am fairly confident that I did manage to stimulate a tiny bit of critical thinking in a tiny percentage of them. The chiropractic profession needs this badly!
According to the ‘General Osteopathic Council’ (GOC), osteopathy is a primary care profession, focusing on the diagnosis, treatment, prevention and rehabilitation of musculoskeletal disorders, and the effects of these conditions on patients’ general health.
Using many of the diagnostic procedures applied in conventional medical assessment, osteopaths seek to restore the optimal functioning of the body, where possible without the use of drugs or surgery. Osteopathy is based on the principle that the body has the ability to heal, and osteopathic care focuses on strengthening the musculoskeletal systems to treat existing conditions and to prevent illness.
Osteopaths’ patient-centred approach to health and well-being means they consider symptoms in the context of the patient’s full medical history, as well as their lifestyle and personal circumstances. This holistic approach ensures that all treatment is tailored to the individual patient.
On a good day, such definitions make me smile; on a bad day, they make me angry. I can think of quite a few professions which would fit this definition just as well or better than osteopathy. What are we supposed to think about a profession that is not even able to provide an adequate definition of itself?
Perhaps I try a different angle: what conditions do osteopaths treat? The GOC informs us that commonly treated conditions include back and neck pain, postural problems, sporting injuries, muscle and joint deterioration, restricted mobility and occupational ill-health.
This statement seems not much better than the previous one. What on earth is ‘muscle and joint deterioration’? It is not a condition that I find in any medical dictionary or textbook. Can anyone think of a broader term than ‘occupational ill health’? This could be anything from tennis elbow to allergies or depression. Do osteopaths treat all of those?
One gets the impression that osteopaths and their GOC are deliberately vague – perhaps because this would diminish the risk of being held to account on any specific issue?
The more one looks into the subject of osteopathy, the more confused one gets. The profession goes back to Andrew Still ((August 6, 1828 – December 12, 1917) Palmer, the founder of chiropractic is said to have been one of Still’s pupils and seems to have ‘borrowed’ most of his concepts from him – even though he always denied this) who defined osteopathy as a science which consists of such exact exhaustive and verifiable knowledge of the structure and functions of the human mechanism, anatomy and physiology & psychology including the chemistry and physics of its known elements as is made discernable certain organic laws and resources within the body itself by which nature under scientific treatment peculiar to osteopathic practice apart from all ordinary methods of extraneous, artificial & medicinal stimulation and in harmonious accord with its own mechanical principles, molecular activities and metabolic processes may recover from displacements, derangements, disorganizations and consequent diseases and regain its normal equilibrium of form and function in health and strength.
This and many other of his statements seem to indicate that the art of using language for obfuscation has a long tradition in osteopathy and goes back directly to its founding father.
What makes the subject of osteopathy particularly confusing is not just the oddity that, in conventional medicine, the term means ‘disease of the bone’ (which renders any literature searches in this area a nightmare) but also the fact that, in different countries, osteopaths are entirely different professionals. In the US, osteopathy has long been fully absorbed by mainstream medicine and there is hardly any difference between MDs and ODs. In the UK, osteopaths are alternative practitioners regulated by statute but are, compared to chiropractors, of minor importance. In Germany, osteopaths are not regulated and fairly ‘low key’, while in France, they are numerous and like to see themselves as primary care physicians.
And what about the evidence base of osteopathy? Well, that’s even more confusing, in my view. Evidence for which treatment? As US osteopaths might use any therapy from drugs to surgery, it could get rather complicated. So let’s just focus on the manual treatment as used by osteopaths outside the US.
Anyone who attempts to critically evaluate the published trial evidence in this area will be struck by at least two phenomena:
- the wide range of conditions treated with osteopathic manual therapy (OMT)
- the fact that there are several groups of researchers that produce one positive result after the next.
The best example is probably the exceedingly productive research team of J. C. Licciardone from the Osteopathic Research Center, University of North Texas. Here are a few conclusions from their clinical studies:
- The large effect size for OMT in providing substantial pain reduction in patients with chronic LBP of high severity was associated with clinically important improvement in back-specific functioning. Thus, OMT may be an attractive option in such patients before proceeding to more invasive and costly treatments.
- The large effect size for short-term efficacy of OMT was driven by stable responders who did not relapse.
- Osteopathic manual treatment has medium to large treatment effects in preventing progressive back-specific dysfunction during the third trimester of pregnancy. The findings are potentially important with respect to direct health care expenditures and indirect costs of work disability during pregnancy.
- Severe somatic dysfunction was present significantly more often in patients with diabetes mellitus than in patients without diabetes mellitus. Patients with diabetes mellitus who received OMT had significant reductions in LBP severity during the 12-week period. Decreased circulating levels of TNF-α may represent a possible mechanism for OMT effects in patients with diabetes mellitus. A larger clinical trial of patients with diabetes mellitus and comorbid chronic LBP is warranted to more definitively assess the efficacy and mechanisms of action of OMT in this population.
- The OMT regimen met or exceeded the Cochrane Back Review Group criterion for a medium effect size in relieving chronic low back pain. It was safe, parsimonious, and well accepted by patients.
- Osteopathic manipulative treatment slows or halts the deterioration of back-specific functioning during the third trimester of pregnancy.
- The only consistent finding in this study was an association between type 2 diabetes mellitus and tissue changes at T11-L2 on the right side. Potential explanations for this finding include reflex viscerosomatic changes directly related to the progression of type 2 diabetes mellitus, a spurious association attributable to confounding visceral diseases, or a chance observation unrelated to type 2 diabetes mellitus. Larger prospective studies are needed to better study osteopathic palpatory findings in type 2 diabetes mellitus.
- OMT significantly reduces low back pain. The level of pain reduction is greater than expected from placebo effects alone and persists for at least three months. Additional research is warranted to elucidate mechanistically how OMT exerts its effects, to determine if OMT benefits are long lasting, and to assess the cost-effectiveness of OMT as a complementary treatment for low back pain.
Based on this brief review of the evidence origination from one of the most active research team, one could be forgiven to think that osteopathy is a panacea. But such an assumption is, of course, nonsensical; a more reasonable conclusion might be the following: osteopathy is one of the most confusing and confused subject under the already confused umbrella of alternative medicine.
– Chronic low back pain (CLBP) is a condition which affects so many people that it represents a huge burden to individual patients’ suffering as well as to society in terms of loss of work time and increased economic cost. The number of therapies that have been claimed to be effective for CLBP can hardly be counted. Two of the most common treatments are spinal manipulation and exercise.
The purpose of this systematic review was to determine the effectiveness of spinal manipulation vs prescribed exercise for patients diagnosed with CLBP. Only RCTs that compared head-to-head spinal manipulation to an exercise group were included in this review.
A search of the current literature was conducted using a keyword process in CINAHL, Cochrane Register of Controlled Trials Database, Medline, and Embase. The searches included studies available up to August 2014. Studies were included based on PICOS criteria 1) individuals with CLBP defined as lasting 12 weeks or longer; 2) spinal manipulation performed by a health care practitioner; 3) prescribed exercise for the treatment of CLBP and monitored by a health care practitioner; 4) measurable clinical outcomes for reducing pain, disability or improving function; 5) randomized controlled trials. The methodological quality of all included articles was determined using the criteria developed and used by the Physiotherapy Evidence Database (PEDro).
Only three RCTs met the inclusion criteria of this systematic review. The outcomes used in these studies included Disability Indexes, Pain Scales and function improvement scales. One RCT found spinal manipulation to be more effective than exercise, and the results of another RCT indicated the reverse. The third RCT found both interventions offering equal effects in the long term.
The author concluded that there is no conclusive evidence that clearly favours spinal manipulation or exercise as more effective in treatment of CLBP. More studies are needed to further explore which intervention is more effective.
Whenever there are uncounted treatments for a given condition, one has to ask oneself whether they are all similarly effective or equally ineffective. The present review does unfortunately not answer this question, but I fear the latter might be more true than the former.
Considering how much money we spend on treating CLBP, it is truly surprising to see that just three RCTs are available comparing two of the most commonly used treatments for this condition. Equally surprising is the fact that we simply cannot tell, on the basis of these data, which of the two therapies is more effective.
What consequences should we draw from this information. Obviously we need more high quality trials. But what should we do in the meantime?
Whenever two treatments are equally effective (or, in this case, perhaps equally ineffective?), we must consider other important criteria such as safety and cost. Regular chiropractic care (chiropractors use spinal manipulation on almost every patient, while osteopaths and physiotherapists employ it less frequently) is neither cheap nor free of serious adverse effects such as strokes; regular exercise has none of these disadvantages. In view of these undeniable facts, it is hard not to come up with anything other than the following recommendation: until new and compelling evidence becomes available, exercise ought to be preferred over spinal manipulation as a treatment of CLBP – and consequently consulting a chiropractor should not be the first choice for CLBP patients.
The Alexander Technique is a method aimed at re-educating people to do everyday tasks with less muscular and mental tension. According to the ‘Complete Guide to the Alexander Technique’, this method can help you if:
- You suffer from repetitive strain injury or carpal tunnel syndrome.
- You have a backache or stiff neck and shoulders.
- You become uncomfortable when sitting at your computer for long periods of time.
- You are a singer, musician, actor, dancer or athlete and feel you are not performing at your full potential.
Sounds good!? But which of these claims are actually supported by sound evidence.
Our own systematic review from 2003 of the Alexander Technique (AT) found just 4 clinical studies. Only two of these trials were methodologically sound and clinically relevant. Their results were promising and implied that AT is effective in reducing the disability of patients suffering from Parkinson’s disease and in improving pain behaviour and disability in patients with back pain. A more recent review concluded as follows: Strong evidence exists for the effectiveness of Alexander Technique lessons for chronic back pain and moderate evidence in Parkinson’s-associated disability. Preliminary evidence suggests that Alexander Technique lessons may lead to improvements in balance skills in the elderly, in general chronic pain, posture, respiratory function and stuttering, but there is insufficient evidence to support recommendations in these areas.
This suggests that the ‘Complete Guide’ is based more on wishful thinking than on evidence. But what about the value of AT for performers – after all, it is for this purpose that Alexander developed his method?
A recent systematic review aimed to evaluate the evidence for the effectiveness of AT sessions on musicians’ performance, anxiety, respiratory function and posture. The following electronic databases were searched up to February 2014 for relevant publications: PUBMED, Google Scholar, CINAHL, EMBASE, AMED, PsycINFO and RILM. The search criteria were “Alexander Technique” AND “music*”. References were searched, and experts and societies of AT or musicians’ medicine contacted for further publications.
In total, 237 citations were assessed. 12 studies were included for further analysis, 5 of which were randomised controlled trials (RCTs), 5 controlled but not randomised (CTs), and 2 mixed methods studies. Main outcome measures in RCTs and CTs were music performance, respiratory function, performance anxiety, body use and posture. Music performance was judged by external experts and found to be improved by AT in 1 of 3 RCTs; in 1 RCT comparing neurofeedback (NF) to AT, only NF caused improvements. Respiratory function was investigated in 2 RCTs, but not improved by AT training. Performance anxiety was mostly assessed by questionnaires and decreased by AT in 2 of 2 RCTs and in 2 of 2 CTs.
From this evidence, the authors drew the following conclusion: A variety of outcome measures have been used to investigate the effectiveness of AT sessions in musicians. Evidence from RCTs and CTs suggests that AT sessions may improve performance anxiety in musicians. Effects on music performance, respiratory function and posture yet remain inconclusive. Future trials with well-established study designs are warranted to further and more reliably explore the potential of AT in the interest of musicians.
So, there you are: if you are a performing artist, AT seems to be useful for you. If you have health problems (other than perhaps back pain), I would look elsewhere for help.
In many countries, consumers seem to be fond of consulting chiropractors – mostly for back pain, but also for other conditions. I therefore think it is might be a good and productive idea to give anyone who is tempted to see a chiropractor some simple, easy to follow advice. Here we go:
- Ask your chiropractor what he/she thinks about the chiropractic concept of subluxation. This is the chiropractors’ term (real doctors use the word too but understand something entirely different by it) for an imagined problem with your spine. Once they have diagnosed you to suffer from subluxation, they will persuade you that it needs correcting which is done by spinal manipulation which they tend to call ‘adjustments’. There are several important issues here: firstly subluxations do not exist outside the fantasy world of chiropractic; secondly chiropractors who believe in subluxation would diagnose subluxation in about 100% of the population – also in individuals who are completely healthy. My advice is to return straight back home as soon as the chiropractor admits he believes in the mystical concept of subluxation.
- Ask your chiropractor what he/she thinks of ‘maintenance care’. This is the term many chiropractors use for indefinite treatments which do little more than transfer lots of cash from your account to that of your chiropractor. There is no good evidence to show that maintenance care does, as chiropractors claim, prevent healthy individuals from falling ill. So, unless you have the irresistible urge to burn money, don’t fall for this nonsense. You should ask your chiropractor how long and frequent your treatment will be, what it will cost, and then ask yourself whether it is worth it.
- Run a mile, if the chiropractor wants to manipulate your neck (which most will do regardless of whether you have neck-pain, some even without informed consent). Neck manipulation is associated with very serious complications; they are usually caused by an injury to an artery that supplies parts of your brain. This can cause a stroke and even death. Several hundred such cases have been documented in the medical literature – but the true figure is almost certainly much larger (there is still no system in place to monitor such events).
- Run even faster, if the chiropractor wants to treat your children for common paediatric conditions. Many chiropractors believe that their manipulations are effective for a wide range of health problems that kids frequently suffer from. However, there is not a jot of evidence that these claims are true.
- Be aware that about 50% of all patients having chiropractic treatments will suffer from side effects like pain and stiffness. These symptoms usually last for 2-3 days and can be severe enough to impede your quality of life. Ask yourself whether the risk is outweighed by the benefit of chiropractic.
- Remember that there is no good evidence that chiropractors can treat any condition effectively other than lower back pain (and even for that condition the evidence is far from strong). Many chiropractors claim to be able to treat a plethora of non-spinal conditions like asthma, ear infection, gastrointestinal complaints, autism etc. etc. There is no good evidence that these claims are correct.
- Distrust the advice given by many chiropractors regarding prescribed medications, vaccinations or surgery. Chiropractic has a long history of warning their patients against all sorts of conventional treatments. Depending on the clinical situation, following such advice can cause very serious harm.
I am minded to write similar posts for all major alternative therapies (this will not make me more popular with alternative therapists, but I don’t mind all that much) – provided, of course, that my readers find this sort of article useful. So, please do give me some feedback.
We all know, I think, that chronic low back pain (CLBP) is common and causes significant suffering in individuals as well as cost to society. Many treatments are on offer but, as we have seen repeatedly on this blog, not one is convincingly effective and some, like chiropractic, is associated with considerable risks.
Enthusiasts claim that hypnotherapy works well, but too little is known about the minimum dose needed to produce meaningful benefits, the roles of home practice and hypnotizability on outcome, or the maintenance of treatment benefits beyond 3 months. A new trial was aimed at addressing these issues.
One hundred veterans with CLBP participated in a randomized, four parallel group study. The groups were (1) an eight-session self-hypnosis training intervention without audio recordings for home practice; (2) an eight-session self-hypnosis training intervention with recordings; (3) a two-session self-hypnosis training intervention with recordings and brief weekly reminder telephone calls; and (4) an eight-session active (biofeedback) control intervention.
Participants in all four groups reported significant pre- to post-treatment improvements in pain intensity, pain interference and sleep quality. The three hypnotherapy groups combined reported significantly more pain intensity reduction than the control group. There was no significant difference among the three hypnotherapy groups. Over half of the participants who received hypnotherapy reported clinically meaningful (≥30%) reductions in pain intensity, and they maintained these benefits for at least 6 months after treatment. Neither hypnotizability nor amount of home practice was associated significantly with treatment outcome.
The authors conclude that two sessions of self-hypnosis training with audio recordings for home practice may be as effective as eight sessions of hypnosis treatment. If replicated in other patient samples, the findings have important implications for the application of hypnosis treatment for chronic pain management.
Even though this trial has several important limitations, I do agree with the authors: these results would be worth an independent replication – not least because self-hypnosis is cheap and does not carry great risks. What would be interesting, in my view, are studies that compare several alternative LBP therapies (e.g. chiropractic, osteopathy, acupuncture, massage, various form of exercise and hypnotherapy) in terms of cost, risks, long-term effectiveness and patients’ preference. I somehow feel that the results of such comparative trials might overturn the often issued recommendations for spinal manipulation, i.e. chiropractic or osteopathy.
