In 1995, Dabbs and Lauretti reviewed the risks of cervical manipulation and compared them to those of non-steroidal, anti-inflammatory drugs (NSAIDs). They concluded that the best evidence indicates that cervical manipulation for neck pain is much safer than the use of NSAIDs, by as much as a factor of several hundred times. This article must be amongst the most-quoted paper by chiropractors, and its conclusion has become somewhat of a chiropractic mantra which is being repeated ad nauseam. For instance, the American Chiropractic Association states that the risks associated with some of the most common treatments for musculoskeletal pain—over-the-counter or prescription nonsteroidal anti-inflammatory drugs (NSAIDS) and prescription painkillers—are significantly greater than those of chiropractic manipulation.
As far as I can see, no further comparative safety-analyses between cervical manipulation and NSAIDs have become available since this 1995 article. It would therefore be time, I think, to conduct new comparative safety and risk/benefit analyses aimed at updating our knowledge in this important area.
Meanwhile, I will attempt a quick assessment of the much-quoted paper by Dabbs and Lauretti with a view of checking how reliable its conclusions truly are.
The most obvious criticism of this article has already been mentioned: it is now 23 years old, and today we know much more about the risks and benefits of these two therapeutic approaches. This point alone should make responsible healthcare professionals think twice before promoting its conclusions.
Equally important is the fact that we still have no surveillance system to monitor the adverse events of spinal manipulation. Consequently, our data on this issue are woefully incomplete, and we have to rely mostly on case reports. Yet, most adverse events remain unpublished and under-reporting is therefore huge. We have shown that, in our UK survey, it amounted to exactly 100%.
To make matters worse, case reports were excluded from the analysis of Dabbs and Lauretti. In fact, they included only articles providing numerical estimates of risk (even reports that reported no adverse effects at all), the opinion of exerts, and a 1993 statistic from a malpractice insurer. None of these sources would lead to reliable incidence figures; they are thus no adequate basis for a comparative analysis.
In contrast, NSAIDs have long been subject to proper post-marketing surveillance systems generating realistic incidence figures of adverse effects which Dabbs and Lauretti were able to use. It is, however, important to note that the figures they did employ were not from patients using NSAIDs for neck pain. Instead they were from patients using NSAIDs for arthritis. Equally important is the fact that they refer to long-term use of NSAIDs, while cervical manipulation is rarely applied long-term. Therefore, the comparison of risks of these two approaches seems not valid.
Moreover, when comparing the risks between cervical manipulation and NSAIDs, Dabbs and Lauretti seemed to have used incidence per manipulation, while for NSAIDs the incidence figures were bases on events per patient using these drugs (the paper is not well-constructed and does not have a methods section; thus, it is often unclear what exactly the authors did investigate and how). Similarly, it remains unclear whether the NSAID-risk refers only to patients who had used the prescribed dose, or whether over-dosing (a phenomenon that surely is not uncommon with patients suffering from chronic arthritis pain) was included in the incidence figures.
It is worth mentioning that the article by Dabbs and Lauretti refers to neck pain only. Many chiropractors have in the past broadened its conclusions to mean that spinal manipulations or chiropractic care are safer than drugs. This is clearly not permissible without sound data to support such claims. As far as I can see, such data do not exist (if anyone knows of such evidence, I would be most thankful to let me see it).
To obtain a fair picture of the risks in a real life situation, one should perhaps also mention that chiropractors often fail to warn patients of the possibility of adverse effects. With NSAIDs, by contrast, patients have, at the very minimum, the drug information leaflets that do warn them of potential harm in full detail.
Finally, one could argue that the effectiveness and costs of the two therapies need careful consideration. The costs for most NSAIDs per day are certainly much lower than those for repeated sessions of manipulations. As to the effectiveness of the treatments, it is clear that NSAIDs do effectively alleviate pain, while the evidence seems far from being conclusively positive in the case of cervical manipulation.
In conclusion, the much-cited paper by Dabbs and Lauretti is out-dated, poor quality, and heavily biased. It provides no sound basis for an evidence-based judgement on the relative risks of cervical manipulation and NSAIDs. The notion that cervical manipulations are safer than NSAIDs is therefore not based on reliable data. Thus, it is misleading and irresponsible to repeat this claim.
The most frequent of all potentially serious adverse events of acupuncture is pneumothorax. It happens when an acupuncture needle penetrates the lungs which subsequently deflate. The pulmonary collapse can be partial or complete as well as one or two sided. This new case-report shows just how serious a pneumothorax can be.
A 52-year-old man underwent acupuncture and cupping treatment at an illegal Chinese medicine clinic for neck and back discomfort. Multiple 0.25 mm × 75 mm needles were utilized and the acupuncture points were located in the middle and on both sides of the upper back and the middle of the lower back. He was admitted to hospital with severe dyspnoea about 30 hours later. On admission, the patient was lucid, was gasping, had apnoea and low respiratory murmur, accompanied by some wheeze in both sides of the lungs. Because of the respiratory difficulty, the patient could hardly speak. After primary physical examination, he was suspected of having a foreign body airway obstruction. Around 30 minutes after admission, the patient suddenly became unconscious and died despite attempts of cardiopulmonary resuscitation.
Whole-body post-mortem computed tomography of the victim revealed the collapse of the both lungs and mediastinal compression, which were also confirmed by autopsy. More than 20 pinprick injuries were found on the skin of the upper and lower back in which multiple pinpricks were located on the body surface projection of the lungs. The cause of death was determined as acute respiratory and circulatory failure due to acupuncture-induced bilateral tension pneumothorax.
The authors caution that acupuncture-induced tension pneumothorax is rare and should be recognized by forensic pathologists. Postmortem computed tomography can be used to detect and accurately evaluate the severity of pneumothorax before autopsy and can play a supporting role in determining the cause of death.
The authors mention that pneumothorax is the most frequent but by no means the only serious complication of acupuncture. Other adverse events include:
- central nervous system injury,
- epidural haematoma,
- subarachnoid haemorrhage,
- cardiac tamponade,
- gallbladder perforation,
No other possible lung diseases that may lead to bilateral spontaneous pneumothorax were found. The needles used in the case left tiny perforations in the victim’s lungs. A small amount of air continued to slowly enter the chest cavities over a long period. The victim possibly tolerated the mild discomfort and did not pay attention when early symptoms appeared. It took 30 hours to develop into symptoms of a severe pneumothorax, and then the victim was sent to the hospital. There he was misdiagnosed, not adequately treated and thus died. I applaud the authors for nevertheless publishing this case-report.
This case occurred in China. Acupuncturists might argue that such things would not happen in Western countries where acupuncturists are fully trained and aware of the danger. They would be mistaken – and alarmingly, there is no surveillance system that could tell us how often serious complications occur.
A pain in the neck is just that: A PAIN IN THE NECK! Unfortunately, this symptom is both common and often difficult to treat. Chiropractors pride themselves of treating neck pain effectively. Yet, the evidence is at best thin, the costs are high and, as often-discussed, the risks might be considerable. Thus, any inexpensive, effective and safe alternative would be welcome.
This RCT tested two hypotheses:
1) that denneroll cervical traction (a very simple device for the rehabilitation of sagittal cervical alignment) will improve the sagittal alignment of the cervical spine.
2) that restoration of normal cervical sagittal alignment will improve both short and long-term outcomes in cervical myofascial pain syndrome patients.
The study included 120 (76 males) patients with chronic myofascial cervical pain syndrome (CMCPS) and defined cervical sagittal posture abnormalities. They were randomly assigned to the control or an intervention group. Both groups received the Integrated neuromuscular inhibition technique (INIT); additionally, the intervention group received the denneroll cervical traction device. Alignment outcomes included two measures of sagittal posture: cervical angle (CV), and shoulder angle (SH). Patient relevant outcome measures included: neck pain intensity (NRS), neck disability (NDI), pressure pain thresholds (PPT), cervical range of motion using the CROM. Measures were assessed at three intervals: baseline, 10 weeks, and 1 year after the 10 week follow up.
After 10 weeks of treatment, between group statistical analysis, showed equal improvements for both the intervention and control groups in NRS and NDI. However, at 10 weeks, there were significant differences between groups favouring the intervention group for PPT and all measures of CROM. Additionally, at 10 weeks the sagittal alignment variables showed significant differences favouring the intervention group for CV and SH indicating improved CSA. Importantly, at the 1-year follow-up, between group analysis identified a regression back to baseline values for the control group for the non-significant group differences (NRS and NDI) at the 10-week mark. Thus, all variables were significantly different between groups favouring the intervention group at 1-year follow up.
The authors concluded that the addition of the denneroll cervical orthotic to a multimodal program positively affected CMCPS outcomes at long term follow up. We speculate the improved sagittal cervical posture alignment outcomes contributed to our findings.
Yes, I know, this study is far from rigorous or conclusive. And the evidence for traction is largely negative. But the device has one huge advantage over chiropractic: it cannot cause much harm. The harm to the wallet is less than that of endless sessions chiropractors or other manual therapists (conceivably, a self-made cushion will have similar effects without any expense); and the chances that patients suffer a stroke are close to zero.
On this blog, I have repeatedly discussed chiropractic research that, on closer examination, turns out to be some deplorable caricature of science. Today, I have another example of what I would call pseudo-research.
This RCT compared short-term treatment (12 weeks) versus long-term management (36 weeks) of back and neck related disability in older adults using spinal manipulative therapy (SMT) combined with supervised rehabilitative exercises (SRE).
Eligible participants were aged 65 and older with back and neck disability for more than 12 weeks. Co-primary outcomes were changes in Oswestry and Neck Disability Index after 36 weeks. An intention to treat approach used linear mixed-model analysis to detect between group differences. Secondary analyses included other self-reported outcomes, adverse events and objective functional measures.
A total of 182 participants were randomized. The short-term and long-term groups demonstrated significant improvements in back and neck disability after 36 weeks, with no difference between groups. The long-term management group experienced greater improvement in neck pain at week 36, self-efficacy at week 36 and 52, functional ability and balance.
The authors concluded that for older adults with chronic back and neck disability, extending management with SMT and SRE from 12 to 36 weeks did not result in any additional important reduction in disability.
What renders this paper particularly fascinating is the fact that its authors include some of the foremost researchers in (and most prominent proponents of) chiropractic today. I therefore find it interesting to critically consider the hypothesis on which this seemingly rigorous study is based.
As far as I can see, it essentially is this:
36 weeks of chiropractic therapy plus exercise leads to better results than 12 weeks of the same treatment.
I find this a most remarkable hypothesis.
Imagine any other form of treatment that is, like SMT, not solidly based on evidence of efficacy. Let’s use a new drug as an example, more precisely a drug for which there is no solid evidence for efficacy or safety. Now let’s assume that the company marketing this drug publishes a trial based on the hypothesis that:
36 weeks of therapy with the new drug plus exercise leads to better results than 12 weeks of the same treatment.
Now let’s assume the authors affiliated with the drug manufacturer concluded from their findings that for patients with chronic back and neck disability, extending drug therapy plus exercise from 12 to 36 weeks did not result in any additional important reduction in disability.
WHAT DO YOU THINK SUCH A TRIAL CAN TELL US?
My answer is ‘next to nothing’.
I think, it merely tells us that
- daft hypotheses lead to daft research,
- even ‘top’ chiropractors have problems with critical thinking,
- SMT might not be the solution to neck and back related disability.
I REST MY CASE.
This study was aimed at evaluating group-level and individual-level change in health-related quality of life among persons with chronic low back pain or neck pain receiving chiropractic care in the United States.
A 3-month longitudinal study was conducted of 2,024 patients with chronic low back pain or neck pain receiving care from 125 chiropractic clinics at 6 locations throughout the US. Ninety-one percent of the sample completed the baseline and 3-month follow-up survey (n = 1,835). Average age was 49, 74% females, and most of the sample had a college degree, were non-Hispanic White, worked full-time, and had an annual income of $60,000 or more. Group-level and individual-level changes on the Patient-Reported Outcomes Measurement Information System (PROMIS) v2.0 profile measure were evaluated: 6 multi-item scales (physical functioning, pain, fatigue, sleep disturbance, social health, emotional distress) and physical and mental health summary scores.
Within group t-tests indicated significant group-level change for all scores except for emotional distress, and these changes represented small improvements in health. From 13% (physical functioning) to 30% (PROMIS-29 Mental Health Summary Score) got better from baseline to 3 months later.
The authors concluded that chiropractic care was associated with significant group-level improvement in health-related quality of life over time, especially in pain. But only a minority of the individuals in the sample got significantly better (“responders”). This study suggests some benefits of chiropractic on functioning and well-being of patients with low back pain or neck pain.
These conclusions are worded carefully to avoid any statement of cause and effect. But I nevertheless feel that the authors strongly imply that chiropractic caused the observed outcomes. This is perhaps most obvious when they state that this study suggests some benefits of chiropractic on functioning and well-being of patients with low back pain or neck pain.
To me, it is obvious that this is wrong. The data are just as consistent with the opposite conclusion. There was no control group. It is therefore conceivable that the patients would have improved more and/or faster, if they had never consulted a chiropractor. The devil’s advocate therefore concludes this: the results of this study suggest that chiropractic has significant detrimental effects on functioning and well-being of patients with low back pain or neck pain.
Try to prove me wrong!
I am concerned that a leading journal (Spine) publishes such rubbish.
Do musculoskeletal conditions contribute to chronic non-musculoskeletal conditions? The authors of a new paper – inspired by chiropractic thinking, it seems – think so. Their meta-analysis was aimed to investigate whether the most common musculoskeletal conditions, namely neck or back pain or osteoarthritis of the knee or hip, contribute to the development of chronic disease.
The authors searched several electronic databases for cohort studies reporting adjusted estimates of the association between baseline neck or back pain or osteoarthritis of the knee or hip and subsequent diagnosis of a chronic disease (cardiovascular disease , cancer, diabetes, chronic respiratory disease or obesity).
There were 13 cohort studies following 3,086,612 people. In the primary meta-analysis of adjusted estimates, osteoarthritis (n= 8 studies) and back pain (n= 2) were the exposures and cardiovascular disease (n=8), cancer (n= 1) and diabetes (n= 1) were the outcomes. Pooled adjusted estimates from these 10 studies showed that people with a musculoskeletal condition have a 17% increase in the rate of developing a chronic disease compared to people without a musculoskeletal condition.
The authors concluded that musculoskeletal conditions may increase the risk of chronic disease. In particular, osteoarthritis appears to increase the risk of developing cardiovascular disease. Prevention and early
treatment of musculoskeletal conditions and targeting associated chronic disease risk factors in people with long
standing musculoskeletal conditions may play a role in preventing other chronic diseases. However, a greater
understanding about why musculoskeletal conditions may increase the risk of chronic disease is needed.
For the most part, this paper reads as if the authors are trying to establish a causal relationship between musculoskeletal problems and systemic diseases at all costs. Even their aim (to investigate whether the most common musculoskeletal conditions, namely neck or back pain or osteoarthritis of the knee or hip, contribute to the development of chronic disease) clearly points in that direction. And certainly, their conclusion that musculoskeletal conditions may increase the risk of chronic disease confirms this suspicion.
In their discussion, they do concede that causality is not proven: While our review question ultimately sought to assess a causal connection between common musculoskeletal conditions and chronic disease, we cannot draw strong conclusions due to poor adjustment, the analysis methods employed by the included studies, and a lack of studies investigating conditions other than OA and cardiovascular disease…We did not find studies that satisfied all of Bradford Hill’s suggested criteria for casual inference (e.g. none estimated dose–response effects) nor did we find studies that used contemporary causal inference methods for observational data (e.g. a structured identification approach for selection of confounding variables or assessment of the effects of unmeasured or residual confounders. As such, we are unable to infer a strong causal connection between musculoskeletal conditions and chronic diseases.
In all honesty, I would see this a little differently: If their review question ultimately sought to assess a causal connection between common musculoskeletal conditions and chronic disease, it was quite simply daft and unscientific. All they could ever hope is to establish associations. Whether these are causal or not is an entirely different issue which is not answerable on the basis of the data they searched for.
An example might make this clearer: people who have yellow stains on their 2nd and 3rd finger often get lung cancer. The yellow fingers are associated with cancer, yet the link is not causal. The association is due to the fact that smoking stains the fingers and causes cancer. What the authors of this new article seem to suggest is that, if we cut off the stained fingers of smokers, we might reduce the cancer risk. This is clearly silly to the extreme.
So, how might the association between musculoskeletal problems and systemic diseases come about? Of course, the authors might be correct and it might be causal. This would delight chiropractors because DD Palmer, their founding father, said that 95% of all diseases are caused by subluxation of the spine, the rest by subluxations of other joints. But there are several other and more likely explanations for this association. For instance, many people with a systemic disease might have had subclinical problems for years. These problems would prevent them from pursuing a healthy life-style which, in turn, resulted is musculoskeletal problems. If this is so, musculoskeletal conditions would not increase the risk of chronic disease, but chronic diseases would lead to musculoskeletal problems.
Don’t get me wrong, I am not claiming that this reverse causality is the truth; I am simply saying that it is one of several possibilities that need to be considered. The fact that the authors failed to do so, is remarkable and suggests that they were bent on demonstrating what they put in their conclusion. And that, to me, is an unfailing sign of poor science.
It is no secret to regular readers of this blog that chiropractic’s effectiveness is unproven for every condition it is currently being promoted for – perhaps with two exceptions: neck pain and back pain. Here we have some encouraging data, but also lots of negative evidence. A new US study falls into the latter category; I am sure chiropractors will not like it, but it does deserve a mention.
This study evaluated the comparative effectiveness of usual care with or without chiropractic care for patients with chronic recurrent musculoskeletal back and neck pain. It was designed as a prospective cohort study using propensity score-matched controls.
Using retrospective electronic health record data, the researchers developed a propensity score model predicting likelihood of chiropractic referral. Eligible patients with back or neck pain were then contacted upon referral for chiropractic care and enrolled in a prospective study. For each referred patient, two propensity score-matched non-referred patients were contacted and enrolled. We followed the participants prospectively for 6 months. The main outcomes included pain severity, interference, and symptom bothersomeness. Secondary outcomes included expenditures for pain-related health care.
Both groups’ (N = 70 referred, 139 non-referred) pain scores improved significantly over the first 3 months, with less change between months 3 and 6. No significant between-group difference was observed. After controlling for variances in baseline costs, total costs during the 6-month post-enrollment follow-up were significantly higher on average in the non-referred versus referred group. Adjusting for differences in age, gender, and Charlson comorbidity index attenuated this finding, which was no longer statistically significant (p = .072).
The authors concluded by stating this: we found no statistically significant difference between the two groups in either patient-reported or economic outcomes. As clinical outcomes were similar, and the provision of chiropractic care did not increase costs, making chiropractic services available provided an additional viable option for patients who prefer this type of care, at no additional expense.
This comes from some of the most-renowned experts in back pain research, and it is certainly an elaborate piece of investigation. Yet, I find the conclusions unreasonable.
Essentially, the authors found that chiropractic has no clinical or economical advantage over other approaches currently used for neck and back pain. So, they say that it a ‘viable option’.
I find this odd and cannot quite follow the logic. In my view, it lacks critical thinking and an attempt to produce progress. If it is true that all treatments were similarly (in)effective – which I can well believe – we still should identify those that have the least potential for harm. That could be exercise, massage therapy or some other modality – but I don’t think it would be chiropractic care.

On this blog, we have often discussed the risks of spinal manipulation. As I see it, the information we have at present suggests that
- mild to moderate adverse effects are extremely frequent and occur in about half of all patients;
- serious adverse effects are being reported regularly;
- the occur usually with chiropractic manipulations of the neck (which are not of proven efficacy for any condition) and often relate to vascular accidents;
- the consequences can be permanent neurological deficits and even deaths;
- under-reporting of such cases might be considerable and therefore precise incidence figures are not available;
- there is no system to accurately monitor the risks;
- chiropractors are in denial of these problems.
Considering the seriousness of these issues, it is important to do more rigorous research. Therefore, any new paper published on this subject is welcome. A recent article might shed new light on the topic.
The objective of this systematic review was to identify characteristics of 1) patients, 2) practitioners, 3) treatment process and 4) adverse events (AE) occurring after cervical spinal manipulation (CSM) or cervical mobilization. A systematic searches were performed in 6 electronic databases up to December 2014. Of the initial 1043 articles thus located, 144 were included, containing 227 cases. 117 cases described male patients with a mean age of 45 and a mean age of 39 for females. Most patients were treated by chiropractors (66%). Manipulation was reported in 95% of the cases, and neck pain was the most frequent indication for the treatment. Cervical arterial dissection (CAD) was reported in 57% of the cases and 45.8% had immediate onset symptoms. The overall distribution of gender for CAD was 55% for female. Patient characteristics were described poorly. No clear patient profile, related to the risk of AE after CSM, could be extracted, except that women seemed more at risk for CAD. The authors of this review concluded that there seems to be under-reporting of cases. Further research should focus on a more uniform and complete registration of AE using standardized terminology.
This article provides little new information; but it does confirm what I have been saying since many years: NECK MANIPULATIONS ARE ASSOCIATED WITH SERIOUS RISKS AND SHOULD THEREFORE BE AVOIDED.
Charlotte Leboeuf-Yde, DC,MPH,PhD, is professor in Clinical Biomechanics at the University of Southern Denmark and works at the French-European Institute of Chiropractic in Paris. She is a chiropractor with extensive research experience, for example, she was one of the first chiropractors to have studied adverse reactions of spinal manipulation.
Charlotte certainly knows a thing or two about adverse effects of spinal manipulation, and I have always found her work interesting. Therefore, I was delighted to find a recent blog post where she discussed the Cassidy study of 2008 and two opposed views on the validity of this much-discussed paper.
One team (Paulus &Thaler) argued, Charlotte explained, that the Cassidy case-control study is faulty, because vertebro-basilar stroke in general was not separated from stroke specifically caused by vertebral artery dissections, the presumed culprit in cervical spinal manipulation. According to Paulus & Thaler, this would potentially result in a dilution of ‘real’ manipulative-related strokes among all other causes of stroke that are much more common. They argue that the Cassidy-analyses therefore were polluted by this misclassification, whereas the other team (Murphy et al) vehemently disagrees.
The final word is clearly not yet pronounced on this issue, Charlotte concluded, and both teams agree that research has to address various methodological challenges to obtain a trustable answer. Nevertheless, without an international collaboration involving prospective cases this seems an almost impossible task, particularly in view of the rarity of the condition; problems in capturing all cases (going from the reversible to the permanent injuries); the likely large anatomical and physiological variations between individuals; and the daunting task of obtaining relevant and precise descriptions of treatments from a multitude of practitioners.
In the meantime, Charlotte concluded, “practitioners and patients have to make a decision, similarly to judging risk in other walks of life, such as, should I take the plane or stay at home?”
I have always thought highly of Charlotte’s work, however, her conclusion made me doubt whether my high opinion of her reasoning was justified.
Should I take the plane or stay at home?
This question is not remotely similar to the question “should I have chiropractic upper neck manipulation or not?”
Here are a the two main reasons why:
- Taking the plane of demonstrably effective in transporting you from A to B, while neck manipulation is not demonstrably effective for anything.
- If you want to go from A to B [assuming B is far way], you need to fly. If you have neck pain or other symptoms, you can employ plenty of therapies other than neck manipulations.
Charlotte Leboeuf-Yde, DC,MPH,PhD, may be a professor in Clinical Biomechanics etc., etc., however, logical and critical thinking do not seem to be her forte.
So, how should we deal with the risks of chiropractic neck manipulations? I think, we should deal with them as responsible healthcare professionals deal with any other suspected therapeutic risks: we must ask whether the known risks of the treatment outweigh the known benefits (as they do with spinal manipulation). If that is so, we have an ethical, legal and moral duty not to employ the therapy in question in routine care. At the same time, we must focus or research efforts on producing full clarity about the open questions. It’s called the precautionary principle!
Tui Na is a massage technique that is based on the Taoist principles of TCM. It involves a range of manipulations usually performed by an operator’s finger, hand, elbow, knee, or foot applied to muscle or soft tissue at specific parts of the body. According to one website of TCM-proponents “Tui Na makes use of various hand techniques in combination with acupuncture and other manipulation techniques. To enhance the healing process, the practitioner may recommend the use of Chinese herbs. Many of the techniques used in this massage resemble that of a western massage like gliding, kneading, vibration, tapping, friction, pulling, rolling, pressing and shaking. In Tui Na massage, the muscles and tendons are massaged with the help of hands, and an acupressure technique is applied to directly affect the flow of Qi at different acupressure points of the body, thus facilitating the healing process. It removes the blockages and keeps the energy moving through the meridians as well as the muscles. A typical session of Tui Na massage may vary from thirty minutes to an hour. The session timings may vary depending on the patient’s needs and condition. The best part of the therapy is that it relaxes as well as energizes the person. The main benefit of Tui Na massage is that it focuses on the specific problem, whether it is an acute or a chronic pain associated with the joints, muscles or a skeletal system. This technique is very beneficial in reducing the pain of neck, shoulders, hips, back, arms, highs, legs and ankle disorders. It is a very effective therapy for arthritis, pain, sciatica and muscle spasms. Other benefits of this massage therapy include alleviation of the stress related disorders like insomnia, constipation, headaches and other disorders related to digestive, respiratory and reproductive systems. The greatest advantage of Tui Na is that it focuses on maintaining overall balance with both physical and mental health. Any one who wants to avoid the side effects of drugs or a chemical based treatment can adopt this effective massage technique to alleviate their pain. Tui Na massage therapy is now becoming a more common therapy method due to its focus on specific problems rather than providing a general treatment.”
This clearly begs the question IS IT EFFECTIVE?
This systematic review assessed the evidence of Tui Na for cervical radiculopathy. Seven databases were searched. Randomised controlled trials (RCTs) incorporating Tui Na alone or Tui Na combined with conventional treatment were included. Five studies involving 448 patients were found. The pooled analysis from the 3 trials indicated that Tui Na alone showed a significant lowering immediate effects on pain score with moderate heterogeneity compared to cervical traction. The meta-analysis from 2 trials revealed significant immediate effects of Tui Na plus cervical traction in improving pain score with no heterogeneity compared to cervical traction alone. None of the RCTs mentioned adverse effects. There was very low quality or low quality evidence to support the results.
The authors concluded that “Tui Na alone or Tui Na plus cervical traction may be helpful to cervical radiculopathy patients, but supportive evidence seems generally weak. Future clinical studies with low risk of bias and adequate follow-up design are recommended.”
In my view, this is a misleading conclusion. A correct one would have been: THE CURRENT EVIDENCE IS INSUFFICIENT TO DRAW ANY CONCLUSIONS ABOUT THE EFFECTIVENESS OF TUI NA.
Here are some of the most obvious reasons:
- there are far too few studies for a firm conclusion,
- the included RCTs lack scientific rigour,
- all trials originate from China where reliability seems to be a serious problem,
- traction is not a useful therapy for radiculopathy,
- the primary studies violate research ethics by not reporting adverse effects.
Personally, I am getting very tired of conclusions stating ‘…XY MAY BE EFFECTIVE/HELPFUL/USEFUL/WORTH A TRY…’ It is obvious that the therapy in question MAY be effective, otherwise one would surely not conduct a systematic review. If a review fails to produce good evidence, it is the authors’ ethical, moral and scientific obligation to state this clearly. If they don’t, they simply misuse science for promotion and mislead the public. Strictly speaking, this amounts to scientific misconduct.
