This study evaluated and compared the effectiveness of Reiki and Qi-gong therapy techniques in improving diabetic patients’ negative emotional states. This quas-experimental research design was carried out at the National Institute of Diabetes and Endocrinology’s Hospital in Cairo, Egypt. It included 200 Type 2 diabetes patients randomized into two equal groups, one for Qigong and one for Reiki techniques. A self-administered questionnaire with a standardized tool (Depression Anxiety Stress Scales [DASS[) was used in data collection. The intervention programs were administered in the form of instructional guidelines through eight sessions for each group.

The results showed that the two study groups had similar socio-demographic characteristics. After implementation of the intervention, most patients in the two groups were having no anxiety, no depression, and no stress. Statistically significant improvements were seen in all three parameters in both groups (p<0.001). The multivariate analysis identified the study intervention as the main statistically significant independent negative predictor of the patients’ scores of anxiety, depression, and stress. Reiki technique was also a statistically significant independent negative predictor of these scores.

The authors conclused that both Reiki and Qi-gong therapy techniques were effective in improving diabetic patients’ negative emotional states of anxiety, depression, and stress, with slight superiority of the Reiki technique. The inclusion of these techniques in the management plans of Type-2 diabetic patients is recommended.

This is an excellent example of how NOT to design a clinical trial!

  • If your aim is to test the efficacy of Reiki, conduct a trial of Reiki versus sham-Reiki.
  • If your aim is to test the efficacy of Qi-gong, conduct a trial of Qi-gong versus sham-Qi-gong.
  • If you compare two therapies in one trial, one has to be of proven and undoubted efficacy.
  • Comparing two treatments of unproven efficacy cannot normally lead to a meaningful result.
  • It is like trying to solve a mathematical equasion with two unknowns.
  • A study that cannot produce a meaningful result is a waste of resorces.
  • It arguably also is a neglect of research ethics.
  • Even if we disregarded all these flaws and problems, recommending therapies for routine use on the basis of one single study is irresponsible nonsense.

All this is truly elementary and should be known by any researcher (not to mention research supervisor). Yet, in the realm of so-called alternative medicine (SCAM), it needs to be stressed over and over again. The ‘National Institute of Diabetes and Endocrinology’s Hospital in Cairo’ (and all other institutions that produce such shameful pseudoscience) urgently need to get their act together:

you are doing nobody a favour!

Spinal manipulation is usually performed by a therapist (chiropractor, osteopath, physiotherpist, doctor, etc.). But many people do it themselves. Self-manipulation is by no means safer than the treatment by a therapist, it seems. We have previously seen cases where the results were dramatic:

Now, a further case has been reported. In this paper, American pathologists present a tragic case of fatal vertebral artery dissection that occurred as the result of self-manipulation of the cervical spine.

The decedent was a 40-year-old man with no significant past medical history. He was observed to “crack his neck” while at work. Soon after, he began experiencing neck pain, then developed stroke-like symptoms and became unresponsive. He was transported to a local medical center, where imaging showed bilateral vertebral artery dissection. His neurological status continued to decline, and brain death was pronounced several days later.

An autopsy examination showed evidence of cerebellar and brainstem infarcts, herniation, and diffuse hypoxic-ischemic injury. A posterior neck dissection was performed to expose the vertebral arteries, which showed grossly visible hemorrhage and dilation. There was no evidence of traumatic injury to the bone or soft tissue of the head or neck. Bilateral dissection tracts were readily appreciated on microscopic examination. Death was attributed to self-manipulation of the neck, which in turn led to bilateral vertebral artery dissection, cerebellar and brainstem infarcts, herniation, hypoxic-ischemic injury, and ultimately brain death.

It seems clear to me that only few and spectacular cases of this nature are being published. In other words, the under-reporting of adverse effects of self-manipulation must be close to 100%. It follows that the risk of sel-manipulation is impossible to quantify. I suspect it is substancial. In any case, the precautionary principle compells me to re-issue my warning:

do not allow anybody to manipulate your neck, not even yourself!

In the realm of so-called alternative medicine (SCAM), we see a lot of papers that are bizarre to the point of being disturbing and often dangerous nonsense. Yesterday, I came across an article that fits this bill well; in fact, I have not seen such misleading BS for quite a while. Let me present to you the abstract of this paper:

Introduction

There has been accumulating interest in the application of biofield therapy as complementary and alternative medicine (CAM) to treat various diseases. The practices include reiki, qigong, blessing, prayer, distant healing, known as biofield therapies. This paper aims to state scientific knowledge on preclinical and clinical studies to validate its potential use as an alternative medicine in the clinic. It also provides a more in-depth context for understanding the potential role of quantum entanglement in the effect of biofield energy therapy.

Content

A comprehensive literature search was performed using the different databases (PubMed, Scopus, Medline, etc.). The published English articles relevant to the scope of this review were considered. The review gathered 45 papers that were considered suitable for the purpose. Based on the results of these papers, it was concluded that biofield energy therapy was effective in treating different disease symptoms in preclinical and clinical studies.

Summary

Biofield therapies offer therapeutic benefits for different human health disorders, and can be used as alternative medicine in clinics for the medically pluralistic world due to the growing interest in CAM worldwide.

Outlook

The effects of the biofield energy therapies are observed due to the healer’s quantum thinking, and transmission of the quantum energy to the subject leads to the healing that occurs spiritually through instantaneous communication at the quantum level via quantum entanglement.

The authors of this article are affiliated with Trivedi Global, an organisation that states this about ‘biofield energy’:

Human Biofield EBnergy has subtle energy that has the capacity to work in an effective manner. This energy can be harnessed and transmitted by the gifted into living and non-living things via the process of a Biofield Energy Healing Treatment or Therapy.

If they aleady know that “Biofield EBnergy has subtle energy that has the capacity to work in an effective manner”, I wonder why they felt the need to conduct this review. Even more wonderous is the fact that their review showed such a positive result.

How did they manage this?

The answer might lie in their methodology: they “gathered 45 papers that were considered suitable”. While scientists gather the totality of the available evidence (and assess it critically), they merely selected what was suitable for the purpose of generating a positive result. This must be the reason our two studies on the subject were discretely omitted:

Our 1st study

Purpose: Distant healing, a treatment that is transmitted by a healer to a patient at another location, is widely used, although good scientific evidence of its efficacy is sparse. This trial was aimed at assessing the efficacy of one form of distant healing on common skin warts.

Subjects and methods: A total of 84 patients with warts were randomly assigned either to a group that received 6 weeks of distant healing by one of 10 experienced healers or to a control group that received a similar preliminary assessment but no distant healing. The primary outcomes were the number of warts and their mean size at the end of the treatment period. Secondary outcomes were the change in Hospital Anxiety and Depression Scale and patients’ subjective experiences. Both the patients and the evaluator were blinded to group assignment.

Results: The baseline characteristics of the patients were similar in the distant healing (n = 41) and control groups (n = 43). The mean number and size of warts per person did not change significantly during the study. The number of warts increased by 0.2 in the healing group and decreased by 1.1 in the control group (difference [healing to control] = -1.3; 95% confidence interval = -1.0 to 3.6, P = 0.25). Six patients in the distant healing group and 8 in the control group reported a subjective improvement (P = 0.63). There were no significant between-group differences in the depression and anxiety scores.

Conclusion: Distant healing from experienced healers had no effect on the number or size of patients’ warts.

Our 2nd study

Spiritual healing is a popular complementary and alternative therapy; in the UK almost 13000 members are registered in nine separate healing organisations. The present randomized clinical trial was designed to investigate the efficacy of healing in the treatment of chronic pain. One hundred and twenty patients suffering from chronic pain, predominantly of neuropathic and nociceptive origin resistant to conventional treatments, were recruited from a Pain Management Clinic. The trial had two parts: face-to-face healing or simulated face-to-face healing for 30 min per week for 8 weeks (part I); and distant healing or no healing for 30 min per week for 8 weeks (part II). The McGill Pain Questionnaire was pre-defined as the primary outcome measure, and sample size was calculated to detect a difference of 8 units on the total pain rating index of this instrument after 8 weeks of healing. VASs for pain, SF36, HAD scale, MYMOP and patient subjective experiences at week 8 were employed as secondary outcome measures. Data from all patients who reached the pre-defined mid-point of 4 weeks (50 subjects in part I and 55 subjects in part II) were included in the analysis. Two baseline measurements of outcome measures were made, 3 weeks apart, and no significant differences were observed between them. After eight sessions there were significant decreases from baseline in McGill Pain Questionnaire total pain rating index score for both groups in part I and for the control group in part II. However, there were no statistically significant differences between healing and control groups in either part. In part I the primary outcome measure decreased from 32.8 (95% CI 28.5-37.0) to 23.3 (16.8-29.7) in the healing group and from 33.1 (27.2-38.9) to 26.1 (19.3-32.9) in the simulated healing group. In part II it changed from 29.6 (24.8-34.4) to 24.0 (18.7-29.4) in the distant healing group and from 31.0 (25.8-36.2) to 21.0 (15.7-26.2) in the no healing group. Subjects in healing groups in both parts I and II reported significantly more ‘unusual experiences’ during the sessions, but the clinical relevance of this is unclear. It was concluded that a specific effect of face-to-face or distant healing on chronic pain could not be demonstrated over eight treatment sessions in these patients.

In addition, they, of course, also omitted many further studies by other investigators that failed to be positive. Considering this amount of cherry-picking, it is easy to understand how they arrived at their conclusion. It is all a question of chosing the right methodology!

A few decades ago, the cigarette industry employed this technique to show that smoking did not cause cancer! Luckily, we have since moved away from such pseudo-scientific ‘research’ – except, of course, in the realm of SCAM where it is still hughely popular.

An interesting and fully referenced (205 references) article caught my attention; it seems highly relevant to the discussions we are having on this blog. Let me show you the abstract:

Medical misinformation has always existed, but it has recently become more frequent due to the development of the internet and social media. Medical misinformation can cover a wide variety of topics, and studies show that some groups are more likely to be affected by medical misinformation than others, like those with less trust in health care, less health literacy, and a more positive attitude toward alternative medicines. Aspects of the internet, like echo chambers and algorithms, have contributed to the rise of medical misinformation, along with belief in anecdotal evidence and alternative remedies that are not backed by science. Some personal beliefs and a lack of media literacy skills are also contributing to medical misinformation. Medical misinformation causes higher rates of death and negative health outcomes, a lack of trust in medical professionals, and more racism and hate crimes. One possible way to combat the spread of misinformation is education surrounding media literacy. Still, there are gaps in this practice that must be addressed like a lack of high-quality research about different educational programs.

The author also offers the following key points:

  • Medical misinformation is becoming an urgent issue for United States citizens—leading to increased deaths,
    a lack of trust in health professionals, and hate crimes and racism.
  • Although this is a worldwide issue, the United States has the second highest rate of misinformation of any
    country, behind India.
  • One piece of misinformation during the COVID-19 pandemic stated that highly concentrated alcohol could
    disinfect the body and kill the virus. Studies show that 800 people died, 5,876 were hospitalized, and 60
    became completely blind from drinking methanol, thinking it would cure coronavirus.
  • Studies estimate that only 14% of the United States population has proficient health literacy, which makes it difficult to recognize medical misinformation.
  • Media literacy education is being pursued in order to combat the spread of misinformation, but more research is needed in order to understand the long-term effects of this education and what programs are best.

__________________

I would like to stress, as indeeed the author does as well, that medical misinformation is a phenomenon that is by no means confined to the US. Like most information, misinformation has become a global issue. Its dangers cannot be under-estimated. My blog offers an abundance of reports where misinformation in the realm of so-called alternative medicine (SCAM) has caused harm and even death. The author advocates media literacy as a remedy for the problem. I would argue that even more important would be to teach CRITICAL THINKING, a task that has to start at school and must continue well into adult life.

This conclusion is so very obvious that it begs an important question: WHY HAS IT NOT BEEN DONE YEARS AGO? The answer, I fear, is simple: for reasons that are self-evident, governments have little interst in the public being able to think critically. On the contrary, governments across the world foremost want to be re-elected, and critical thinking would be a major obstacle to this aim.

 

In spite of the safety and efficiency of the COVID-19 vaccines and the many promotion efforts of political and expert authorities, a fair portion of the population remained hesitant if not opposed to vaccination. Public debate and the available literature point to the possible role of people’s attitudes towards medical institutions as well as their preference for so-called alternative medicine (SCAM) on their motivations and intentions to be vaccinated. Other potential ideological factors are beliefs about environmental laissez-faire and divine providence insofar as they encourage people to let the pandemic unfold without human interference.

In three cross-sectional samples (total N = 8214), collected at successive moments during the Belgian vaccination campaign, the present research examines the distal role of these psychological and ideological factors on vaccination intentions via motivational processes.

  • Study 1 gauges the relation between trust in medical institutions and preference for SCAM on intentions to get vaccinated via motivations.
  • Study 2 examines the role of beliefs in the desirability of letting nature take its course (‘environmental laissez-faire beliefs’) on vaccination intention via motivations.
  • Study 3 tests whether people’s adherence to environmental laissez-faire and beliefs about divine providence are linked to their motivations for vaccination via trust in the medical institutions and SCAM.

The results show that adherence to SCAM has a deleterious effect on vaccination intentions, whereas trust in medical institutions has a positive effect. Both ideological factors pertaining to external control are only moderately related, with environmental laissez-faire beliefs having stronger effects on SCAM, medical trust and vaccination motivations.

The evidence of an association between SCAM and willingness to get vaccinated is undeniable. On this blog, we have discussed it repeatedly, e.g.:

But what exactly is the nature of this association?

  • Does SCAM-use predispose to vaccination hesitancy?
  • Does Vaccination hesitancy predispose to SCAM use?
  • Is both true?

After reading all this research that has emerged on the subject, I get the impression that we are mostly dealing here with a cross-correlation where a certain mind-set of being

  • prone to conspiracy theories,
  • anti-establishment,
  • anti-science,
  • irrational,
  • of low intelligence,
  • unable of critical thinking,
  • etc., etc,

determines both the SCAM-use and the vaccination hesitancy.

 

It has been reported that 5 people who took a Japanese health supplement have died and more than 100 have been hospitalized as of Friday, a week after a pharmaceutical company issued a recall of the products, officials said. Osaka-based Kobayashi Pharmaceutical Co. came under fire for not going public quickly with problems known internally as early as January. Yet the first public announcement came only on 22 March. Company officials said 114 people were being treated in hospitals after taking products — including Benikoji Choleste Help meant to lower cholesterol — that contain an ingredient called benikoji, a red species of mold. Some people developed kidney problems after taking the supplements, but the exact cause was still under investigation in cooperation with government laboratories, according to the manufacturer.

“We apologize deeply,” President Akihiro Kobayashi told reporters last Friday, bowing for a long time to emphasize the apology alongside three other top company officials. He expressed remorse to those who have died and have been taken ill and to their families. He also apologized for the troubles caused to the entire health food industry and the medical profession, adding that the company was working to prevent further damage and improve crisis management.

The company’s products have been recalled — as have dozens of other products that contain benikoji, including miso paste, crackers, and a vinegar dressing. Japan’s health ministry put up a list on its official site of all the recalled products, including some that use benikoji for food coloring. The ministry warned the deaths could keep growing. The supplements could be bought at drug stores without a prescription from a doctor, and some may have been purchased or exported before the recall, including by tourists who may not be aware of the health risks.

Kobayashi Pharmaceutical had been selling benikoji products for years, with a million packages sold over the past 3 fiscal years, but a problem crept up with the supplements produced in 2023. Kobayashi Pharmaceutical said it produced 18.5 tons of benikoji last year. Some analysts blame the recent deregulation initiatives, which simplified and sped up approval for health products to spur economic growth.

________________________

Anouther source reported that Japanese authorities on Saturday raided a drug factory after a pharmaceutical company reported at least five deaths and 114 hospitalizations possibly linked to a health supplement. About a dozen Japanese health officials walked into the Osaka plant of the Kobayashi Pharmaceutical Co., as seen in footage of the raid widely telecasted on Japanese news. The health supplement in question is a pink pill called Benikoji Choleste Help. It is said to help lower cholesterol levels. A key ingredient is benikoji, a type of red mold. The company has said it knows little about the cause of the sickness, which can include kidney failure. It is currently investigating the effects in cooperation with Japan’s government.

___________________________

More recent reports update the figure of affected individuals: Japanese dietary supplements at the center of an expanding health scare have now been linked to at least 157 hospitalizations, a health ministry official said Tuesday.The figure reflects an increase from the 114 hospitalization cases that Kobayashi Pharmaceutical said on Friday were linked to its products containing red yeast rice, or beni kōji.

____________________________

A Kobayashi Pharmaceutical spokeswoman confirmed the latest hospitalization cases without elaborating further.

Benikoji is widely sold and used; not just in Japan. It comes under a range of different names:

  • red yeast rice,
  • red fermented rice,
  • red kojic rice,
  • red koji rice,
  • anka,
  • angkak,
  • Ben Cao Gang Mu.

It is a bright reddish purple fermented rice which acquires its color from being cultivated with the mold Monascus purpureus. Red yeast rice is used as food and as a medicine in Asian cultures, such as Kampo and TCM.

It contains lovastatin which, of course, became patented  and is marketed as the prescription drug, Mevacor. Red yeast rice went on to become a non-prescription dietary supplement in the United States and other countries. In 1998, the U.S. FDA banned a dietary supplement containing red yeast rice extract, stating that red yeast rice products containing monacolin K are identical to a prescription drug, and thus subject to regulation as a drug.

Cervical spondylosis is a chronic degenerative process of the cervical spine characterized by pain in neck, degenerative changes in intervertebral disc and osteophyte formation. The present study was aimed at evaluating the effect of wet cupping (Ḥijāma Bish Sharṭ) in the pain management of cervical spondylosis.

This Open, randomized, clinical study was conducted on 44 patients.

  • Subjects in the test group (n = 22) received a series of three-staged wet cupping treatment, performed on 0, 7th and 14th day.
  • Subjects in the control group (n = 22) received 12 sittings of Transcutaneous Electrical Nerve Stimulation (TENS): 6 sittings per week for two weeks.

The outcomes were assessed with the help of VAS, Neck Disability Index (NDI) and Cervical range of motion.

Intra group comparison in test group from baseline to 21st day were found highly significant (p < 0.001) in terms of VAS, NDI, Flexion, Extension and Left rotation score. While in Right rotation, Left rotation and Left lateral flexion score were found moderately significant (p < 0.01). Statistically significant difference was observed between two groups at 21st day in VAS scale, NDI, and Cervical range of motion score (p < 0.001).

The authors concluded that Ḥijāma Bish Sharṭ was found better in the management of pain due to cervical spondylosis than TENS. It can be concluded that Ḥijāma Bish Sharṭ may a better option for the pain management of cervical spondylosis.

Wet cupping is the use of a vacuum cup applied to the skin which has previously been lacerated. It draws blood and can thus be seen as a form of blood letting. It has been used in various cultures for the treatment of joint pain and many other conditions since antiquity.

The authors point out that, in Unani medicine, it is believed to reduce pain and other symptoms by diverting and evacuating the causative pathological humours (akhlāṭ-e-fasida). Galen (Jalinoos) mentioned wet cupping as a very useful modality in evacuating the thick humours (akhlāṭ-e-Ghaleez) (Nafeesi, 1954; Qamri, 2008). Wet cupping works on the principle of diversion and evacuation of morbid matter (imala wa tanqiya-i-mawād-i-fasida). It opens the pores of the skin, enhances the blood circulation, nourishes the affected area with fresh blood, improves the eliminative function and facilitates the evacuation of morbid matter from the body.

There are several studies of wet cupping, most of which are as flawed as the one above. This new trial has several limitations, e.g.:

  • It makes no attempt to control for placebo effects which could well be more prominent for wet cupping than for TENS.
  • It did not inhibit the influence of verbal or non-verbal communications between therapists and patients which are likely to influence the results.
  • The sample size is far too small, particularly as the study was designed as an equivalence study.

But some might say that my arguments a petty and argue that, regardless of a flimsy study, wet cupping is still worth a try. I would disagree – not because of the flaws of this study, nor the implausibility of the long-obsolete assumptions that underpin the therapy, but because wet cupping is associaated with infections of the skin lacerations which occasionally can be serious.

 

It does not happen often, but when it does, it should be aknowledged. I am speaking of papers from chiropractors that make sense. If you are interested in chiropractic, I do encourage you to read the articles of which I will here only present bits of the conclusions:

Part 1

The chiropractic profession is weighed down by the burden of historical theories regarding spinal manipulative therapy (SMT), which, for some in the profession, have all the characteristics of dogmatic articles of faith. In our opinion, the unlimited scope of practice, which is still advocated by some chiropractors, and which has not been met with unequivocal political rejection, an over-reliance on SMT in the management of MSK disorders, and an over-emphasis on the technical intricacies of SMT represent weaknesses within chiropractic. We argue that these are obstacles to professional development and the major causes of professional stagnation both intellectually and in the market place.

We also discussed what we consider to be threats to the chiropractic profession. Science, the impact of EBM, and accountability to authorities and third party-payers all pose threats to the traditional chiropractic paradigm and, thus, to those within the profession, who practice within such a paradigm. In the marketplace, competition from other professions that provide care of patients with MSK disorders, including SMT, and are better positioned to be integrated into the wider health-care system/market represent a threat. Moreover, finally, the internal schism in chiropractic represents a threat to professional development, as it prevents the profession moving forward in unison with a coherent external message.

We have described those weaknesses and threats, knowing full well, that we do so from our perspective of chiropractic as EBM with a limited MSK scope of practice, i.e. from outside the subluxation frame of reference.

We recognize that for those who look at SMT from the perspective of traditional, subluxation-based chiropractic, things will look very different: What we identify as weaknesses may be seen by others as the pillars of chiropractic practice, and what we see as threats could appear as just peripheral and ephemeral distractions to the enduring core of chiropractic ideas. Such is the character of the schism at the heart of chiropractic.

None-the-less, having described what we identify as serious weaknesses and threats arising from the profession’s relationship to SMT, it has not escaped our attention that it also gives rise to several strengths, which serve the profession and its patients well. In turn, it follows that a number of opportunities are presenting themselves for the future of SMT and chiropractic.

Part 2

The onus is now on the chiropractic profession itself to redefine its raison d’être in a way that plays to those strengths and delivers in terms of the needs of patients and the wider healthcare system/market. We suggest chiropractors embrace and cultivate a role as coordinators of long-term and broad-focused management of musculoskeletal disorders. We make specific recommendations about how the profession, from individual clinicians to political organizations, can promote such a development.

___________________________

For readers in a hurry:

Progress is an inevitable threat to obsolete and useless practices of any kind. In that, chiropractic is no exception.

Some abstracts of medical papers are so bizarre that they must not be tempered with, I find. This is one of them:

Rationale:

This case report aims to provide clinical evidence on the effectiveness of integrating chiropractic and moxibustion techniques for treating pseudomyopia accompanied by elevated intraocular pressure resulting from cervical spine issues because the application of complementary medicine modalities for managing such vision disorders currently lacks adequate investigations.

Patient concerns:

A 6-year-old patient presented with blurred vision, intermittent ocular discomfort, and upper cervical discomfort.

Diagnoses:

Spine-related increased intraocular pressure and pseudomyopia.

Interventions:

The patient received integrative treatment of chiropractic and walnut-shell moxibustion 3 times a week for a total of 10 treatment sessions.

Outcomes:

The patient exhibited progressive improvements in visual acuity and reductions in intraocular pressure over the treatment period, with unaided vision exceeding 2 lines of improvement in visual acuity charts and normalized intraocular pressure after 10 treatment sessions. These therapeutic effects were sustained at 3-month follow-up.

Lessons:

The integrative use of chiropractic and walnut-shell moxibustion demonstrates considerable potential in alleviating symptoms of pseudomyopia, reducing intraocular pressure, and restoring visual function in spine-related pseudomyopia cases.

Pseudomyopia is a spasm of the ciliary muscle that prevents the eye from focusing in the distance. It differs from myopia which is caused by the eye’s shape or other basic anatomy. Pseudomyopia may be either organic, through stimulation of the parasympathetic nervous system, or functional in origin, through eye strain or fatigue of ocular systems. It is common in young adults after a change in visual requirements, such as students preparing for an exam, or a change in occupation. The condition is often transitory and it is necessary to request psychiatric consultation in each case of pseudomyopia. Comorbidity of anxiety and depressive disorders is more common in pseudomyopia cases. In addition, as the severity of psychiatric symptoms increases, the amount of accommodation also appears to increase.

A few question, if I may:

  • Walnut-shell moxibustion? Yes, it exists! Moxibustion with walnut shell spectacles is a characteristic therapy of Guang’anmen Hospital, developed on the basis of walnut shell moxibustion, and mainly composed of an eye moxibustion frame, a walnut shell soaked with wolfberry and chrysanthemum liquid, and moxibustion strips. Moxibustion with a walnut shell was first recorded by Shicheng Gu for treating surgical ulcers in the Qing dynasty. Then, moxibustion with walnut shell spectacles was reformed by us, combining Shicheng Gu’s experience with our clinical practice, and is mainly used for the treatment of optic nerve atrophy and myopia.
  • The authors state that, “based on traditional Chinese medicine principles, moxibustion is known to warm meridians, dredge collaterals, relax tendons, and enhance blood circulation”. Is this true? Well, based on TCM, anything goes, but it does not make it true.
  • How can we know whether chiropractic or walnut-shell moxibustion or both caused the outcome? We can’t!
  • Can we be sure what caused the child’s problem? No!
  • Do we know whether the outcome was not a spontaneous recovery? No!
  • The authors claim that “cervical spine imbalance leads to visual impairment”. Is that correct? Not as far as I know.
  • The authors state that “the patient in this case, presenting with pseudomyopia, elevated intraocular pressure, and neck pain, likely had a cervical spine-derived condition. Currently, such spine-derived vision disorders lack sufficient clinical recognition.” Is this true? No, I’d say such spine-derived vision disorders might not even exist.
  • Why would anyone publish a paper about the case? Search me!

 

Lumbar stabilization exercises (LSEs) are said to be beneficial for chronic mechanical low back pain (CMLBP). However, further research focusing on intervention combinations is recommended. This study examined the effect of kinesio tape (KT) with LSEs on CMLBP adult patients.

A randomized blinded clinical trial was conducted. Fifty CMLBP patients of both genders were assigned into one of two groups and received 8 weeks of treatment:

  • group A (control): LSEs only,
  • group B (experimental): KT with LSEs.

The primary outcome was back disability, measured by the Oswestry disability index. Secondary outcomes included pain intensity, trunk extensor endurance, and sagittal spinal alignment, as indicated by the visual analog scale, Sorensen-test, and C7–S1 sagittal vertical axis, respectively. The reported data was analyzed by a two-way MANOVA using an intention-to-treat procedure.

Multivariate tests indicate statistically significant effects for group (F = 4.42, p = 0.005, partial η2 = 0.148), time (F = 219.55, p < 0.001, partial η2 = 0.904), and group-by-time interaction (F = 3.21, p = 0.01, partial η2 = 0.149). Univariate comparisons between groups revealed significant reductions in the experimental group regarding disability (p = 0.029, partial η2 = 0.049) and pain (p = 0.001, partial η2 = 0.102) without a significant difference in the Sorensen test (p = 0.281) or C7–S1 SVA (p = 0.491) results. All within-group comparisons were statistically significant (p < 0.001).

The authors concluded that the combination of KT and LSEs is an effective CMLBP treatment option. Although patients in both groups displayed significant changes in all outcomes, the combined interventions induced more significant reductions in back disability and pain intensity.

One of the main reason for conducting a controlled clinical trial is to determine whether the intervention, rather than some other factor, was the cause of the observed outcome. Yet, these trials can be designed in such a way that they mislead us on precisely this point. The present study is an example for such a case.

The authors leave us in no doubt that the KT was the cause of the positive outcome. However, they might be entirely wrong. Here are some other possibilities:

  • the extra attention might have done the trick;
  • the ritual of applying KT must have an effect;
  • the expectation of the patient could have influenced the outcome;
  • verbal or non-verbal communication between the patient and the therapist would have had an effect.

I know, it is often difficult to control for such influences in clinical trials. But, if it proves to be impossible [and in the case of KT it probably is possible], one should at the very least be cautious when drawing conclusions from the results. I suggest something like this:

The combination of KT and LSEs generated better outcomes than LSE alone. Whether this is due to specific effects of KT or non-specific context effects remains unclear.
