Reflexology (originally called ‘zone therapy’ by its inventor) is a manual technique where pressure is applied to the sole of the patient’s foot. Reflexology is said to have its roots in ancient cultures. Its current popularity goes back to the US doctor William Fitzgerald (1872-1942) who did some research in the early 1900s and thought to have discovered that the human body is divided into 10 zones each of which is represented on the sole of the foot. Reflexologists thus drew maps of the sole of the foot where all the body’s organs are depicted. Numerous such maps have been published and, embarrassingly, they do not all agree with each other as to the location of our organs on the sole of our feet. By massaging specific zones which are assumed to be connected to specific organs, reflexologists believe to positively influence the function of these organs.
So, does reflexology do more good than harm?
The aim of this review was to conduct a systematic review, meta-analysis, and metaregression to determine the current best available evidence of the efficacy and safety of foot reflexology for adult depression, anxiety, and sleep quality.
Twenty-six studies could be included. The meta-analyses showed that foot reflexology intervention significantly improved adult depression, anxiety, and sleep quality. Metaregression revealed that an increase in total foot reflexology time and duration can significantly improve sleep quality.
The authors concluded that foot reflexology may provide additional nonpharmacotherapy intervention for adults suffering from depression, anxiety, or sleep disturbance. However, high quality and rigorous design RCTs in specific population, along with an increase in participants, and a long-term follow-up are recommended in the future.
Finally a so-called alternative medicine (SCAM) that is backed by soild evidence!
Or perhaps not?
Here are a few concerns that lead me to doubt these conclusions:
- Most of the primary studies were of poor methodological quality.
- Most studies failed to mention adverse effects.
- Very few studies controlled for placebo effects.
- There was evidence of publication bias (negative studies tended to remain unpublished).
- Studies published in languages other than English were not considered.
- The authors fail to point out that a foot massage is, of course, agreeable (and thus may relieve a range of symptoms), but reflexology with all its weird assumptions is less than plausible.
- Many of the studies located by the authors were excluded for reasons that are less than clear.
The last point seems particularly puzzling. Our own trial, for instance, was excluded because, according to the review authors, it did not include relevant outcomes. However, our method secion makes it clear that the primary focus for this study was the subscores for anxiety and depression, which comprise four and seven items, respectively. As it happens, our study was negative.
Also cuirous is the fact that the authors did not mention our own 2011 systematic review of reflexology:
Reflexology is a popular form of complementary and alternative medicine (CAM). The aim of this update is to critically evaluate the evidence for or against the effectiveness of reflexology in patients with any type of medical condition. Six electronic databases were searched to identify all relevant randomised clinical trials (RCTs). Their methodological quality was assessed independently by the two reviewers using the Jadad score. Overall, 23 studies met all inclusion criteria. They related to a wide range of medical conditions. The methodological quality of the RCTs was often poor. Nine high quality RCTs generated negative findings; and five generated positive findings. Eight RCTs suggested that reflexology is effective for the following conditions: diabetes, premenstrual syndrome, cancer patients, multiple sclerosis, symptomatic idiopathic detrusor over-activity and dementia yet important caveats remain. It is concluded that the best clinical evidence does not demonstrate convincingly reflexology to be an effective treatment for any medical condition.
I wonder why!
Highly diluted homeopathic remedies are pure placebos! This is what the best evidence clearly shows. Ergo they cannot be shown in a rigorous study to have effects that differ from placebo. But now there is a study that seems to contradict this widely accepted conclusion.
Can someone please help me to understand what is going on?
In this double-blind, placebo-controlled RCT, 60 patients suffering from insomnia were treated either individualised homeopathy (IH) or placebo for 3 months. Patient-administered sleep diary and Insomnia Severity Index (ISI) were used the primary and secondary outcomes respectively, measured at baseline, and after 3 months.
Five patients dropped out (verum:2,control:3).Intention to treat sample (n=60) was analysed. Trial arms were comparable at baseline. In the verum group, except sleep diary item 3 (P= 0.371), rest of the outcomes improved significantly (all P < 0.01). In the control group, there were significant improvements in diary item 6 and ISI score (P < 0.01) and just significant improvement in item 5 (P= 0.018). Group differences were significant for items 4, 5 and 6(P < 0.01) and just significant (P= 0.014) for ISI score with moderate to large effect sizes; but non-significant (P > 0.01) for rest of the outcomes.
The authors concluded that in this double-blind, randomized, prospective, placebo-controlled, two parallel arms clinical trial conducted on 60 patients suffering from insomnia, there was statistically significant difference measured in sleep efficiency, total sleep time, time in bed, and ISI score in favour of homeopathy over placebo with moderate to large effect sizes. Group differences were non-significant for rest of the outcomes(i.e. latency to fall asleep, minutes awake in middle of night and minutes awake too early). Individualized homeopathy seemed to produce significantly better effect than placebo. Independent replications and adequately powered trials with enhanced methodological rigor are warranted.
I have studied this article in some detail; its methodology is nicely and fully described in the original paper. To my amazement, I cannot find a flaw that is worth mentioning. Sure, the sample was small, the treatment time short, the outcome measure subjective, the paper comes from a dubious journal, the authors have a clear conflict of interest, even though they deny it – but none of these limitations has the potential to conclusively explain the positive result.
In view of what I stated above and considering what the clinical evidence so far tells us, this is most puzzling.
A 2010 systematic review authored by proponents of homeopathy included 4 RCTs comparing homeopathic medicines to placebo. All involved small patient numbers and were of low methodological quality. None demonstrated a statistically significant difference in outcomes between groups.
My own 2011 not Medline-listed review (Focus on Alternative and Complementary Therapies Volume 16(3) September 2011 195–199) included several additional studies. Here is its abstract:
The aim of this review was the critical evaluation of evidence for the effectiveness of homeopathy for insomnia and sleep-related disorders. A search of MEDLINE, AMED, CINAHL, EMBASE and Cochrane Central Register was conducted to find RCTs using any form of homeopathy for the treatment of insomnia or sleep-related disorders. Data were extracted according to pre-defined criteria; risk of bias was assessed using Cochrane criteria. Six randomised, placebo-controlled trials met the inclusion criteria. Two studies used individualised homeopathy, and four used standardised homeopathic treatment. All studies had significant flaws; small sample size was the most prevalent limitation. The results of one study suggested that homeopathic remedies were superior to placebo; however, five trials found no significant differences between homeopathy and placebo for any of the main outcomes. Evidence from RCTs does not show homeopathy to be an effective treatment for insomnia and sleep-related disorders.
It follows that the new trial contradicts previously published evidence. In addition, it clearly lacks plausibility, as the remedies used were highly diluted and therefore should be pure placebos. So, what could be the explanation of the new, positive result?
As far as I can see, there are the following possibilities:
- some undetected/undisclosed bias,
- homeopathy works after all.
I would be most grateful, if someone could help solving this puzzle for me (if needed, I can send you the full text of the new article for assessment).
Doubtlessly, you will have noted that homeopathy missed out yet again at this year’s Nobels. Personally, I am convinced that this is all due to the evil propaganda put about by malicious sceptics (paid lavishly by BIG PHARMA, of course). But all is not lost! Down under, ‘CHOICE’ do know what is truly prize-worthy!
The Australian Consumers’ Association ‘CHOICE’ reviews everyday items like aspirin, detergents and instant coffee – but also major purchases like cars and washing machines. Each year, CHOICE awards ‘SHONKIES’ (from ‘shonky‘ = dishonest, unreliable, or illegal, especially in a devious way). CHOICE receive hundreds of nominations for Shonky products and services from CHOICE members and staff. While some Shonky nominees may not be breaking laws or breaching regulations – though sometimes they are – they believe that consumers deserve better products and services.
And how do they decide which nominations make the cut?
First and foremost, a nomination has to meet one or more of the following Shonky criteria:
- Fails a standard
- Poor performance on CHOICE tests
- Hidden charges
- Lack of transparency
- False claims or broken promises
- Consumers are worse off because of it
- Consumer confusion
- Poor value for money
- Consumer frustration, or just plain outrage
Products that meet one or more of these criteria make it to the short list. From there CHOICE look at how the issue will resonate with consumers, as well as government authorities and the media, which have the power to prod companies to pick up their act.
This year, CHOICE awarded 7 shonkies. My favourite, of course, is the award for trickery that leaves people sleepless – here is what CHOICE tell us about it:
Big pharmaceutical companies, or ‘big pharma’, are synonymous with big medical production, big money and a big impact on the type of healthcare products we can access. One thing that’s rarely expected from big pharma is homeopathic cures, which are more typically found in the domain of alternative therapies.
However, at least one big pharma company in Australia is selling homeopathic products on a very large scale. Pharmacare, which boasts on LinkedIn that it’s “the largest private, Australian-owned consumer health, fitness and consumer goods company in the country”, currently operates 23 brands, including Bioglan. According to their website, their products are available in “5200 pharmacies, 3000 supermarket outlets, department and variety stores nationwide, and hundreds of overseas outlets in Asia, America and Europe.”
In 2017, we awarded Bioglan and another Pharmacare brand, Nature’s Way, a Shonky for its outrageous claims that sticky, sugary lollies are in fact good for teeth. This year, Pharmacare and Bioglan receive another dubious honour for its over-the-counter Melatonin Homeopathic Sleep Formula. While melatonin (currently a prescription-only medicine in Australia) is known to promote sleep and is used to help people suffering jet lag or sleep disorders, there’s no reliable evidence that homeopathic melatonin (or homeopathic products in general) has any effect other than as a placebo. Despite this, the company makes the claim that Bioglan Melatonin helps “relieve mild temporary insomnia and symptoms of mild nervous tension”.
Bioglan’s Melatonin Homeopathic Sleep Formula is also available in chewable tablet form or spray and both products promise to “relieve mild temporary insomnia”.
On the product’s web page, we’re told “results depend on how often the homeopathic remedy is taken, not on the quantity used”, because in homeopathy, “the amount consumed is not relevant, children are treated in the same way as adults”.
However, directions for the tablet version state, “To aid sleep: Chew 3-5 tablets half an hour before bedtime”, while the spray is “rapidly absorbed to start working quickly”.
To be fair to Bioglan, consuming more does support the primary reason for this product’s existence – the more tablets people chew, the sooner they’ll potentially cough up another $24.50 (RRP).
Melatonin Homeopathic Sleep Formula is packaged like medication and sold in a pharmacy. But with murky claims that are not supported with evidence, wasting money is the only area where this product is proven to be effective. Not only does Bioglan Melatonin not help you sleep, it’s Shonky enough that you might lose sleep worrying about the brazen trickery this company gets away with.
END OF QUOTE
As I said, it’s not a Nobel, but it’s certainly a start.
My heart-felt congratulations to homeopaths across the world!
Insomnia is a ‘gold standard’ indication for alternative therapies of all types. In fact, it is difficult to find a single of these treatments that are not being touted for this indication. Consequently, it has become a nice little earner for alternative therapists (hence ‘gold standard’).
But how good is the evidence suggesting that any alternative therapy is effective for insomnia?
Whenever I have discussed this issue on my blog, the conclusion was that the evidence is less than convincing or even negative. Similarly, whenever I conducted proper systematic reviews in this area, the evidence turned out to be weak or negative. Here are four of the conclusions we drew at the time:
- The evidence for acupuncture as a treatment of insomnia is plagued by important limitations, e.g. the poor quality of most primary studies and some systematic reviews. Those that are sensitive to such limitations, fail to arrive at a positive verdict about the effectiveness of acupuncture.
- We conclude that, because of the paucity and of the poor quality of the data, the evidence for the effectiveness of auricular acupuncture for the symptomatic treatment of insomnia is limited. Further, rigorously designed trials are warranted to confirm these results.
- The evidence for valerian as a treatment for insomnia is inconclusive.
- Evidence from RCTs does not show homeopathy to be an effective treatment for insomnia and sleep-related disorders. (FACT, 2011, 16:195-99)
“But this ERNST fellow cannot be trusted, he is not objective!”, I hear some of my detractors shout.
But is he really?
Would an independent, high-level panel of experts arrive at more positive conclusions?
Let’s find out!
This European guideline for the diagnosis and treatment of insomnia recently provided recommendations for the management of adult patients with insomnia. The guideline is based on a systematic review of relevant meta-analyses published till June 2016. The GRADE (Grading of Recommendations Assessment, Development and Evaluation) system was used to grade the evidence and guide recommendations.
The findings and recommendations are as follows:
- Cognitive behavioural therapy for insomnia is recommended as the first-line treatment for chronic insomnia in adults of any age (strong recommendation, high-quality evidence).
- A pharmacological intervention can be offered if cognitive behavioural therapy for insomnia is not sufficiently effective or not available. Benzodiazepines, benzodiazepine receptor agonists and some antidepressants are effective in the short-term treatment of insomnia (≤4 weeks; weak recommendation, moderate-quality evidence). Antihistamines, antipsychotics, melatonin and phytotherapeutics are not recommended for insomnia treatment (strong to weak recommendations, low- to very-low-quality evidence).
- Light therapy and exercise need to be further evaluated to judge their usefulness in the treatment of insomnia (weak recommendation, low-quality evidence).
- Complementary and alternative treatments (e.g. homeopathy, acupuncture) are not recommended for insomnia treatment (weak recommendation, very-low-quality evidence).
I think, I can rest my case.
Of all alternative treatments, aromatherapy (i.e. the application of essential oils to the body, usually by gentle massage or simply inhalation) seems to be the most popular. This is perhaps understandable because it certainly is an agreeable form of ‘pampering’ for someone in need of come TLC. But is aromatherapy more than that? Is it truly a ‘THERAPY’?
A recent systematic review was aimed at evaluating the existing data on aromatherapy interventions as a means of improving the quality of sleep. Electronic literature searches were performed to identify relevant studies published between 2000 and August 2013. Randomized controlled and quasi-experimental trials that included aromatherapy for the improvement of sleep quality were considered for inclusion. Of the 245 publications identified, 13 studies met the inclusion criteria, and 12 studies could be used for a meta-analysis.
The meta-analysis of the 12 studies revealed that the use of aromatherapy was effective in improving sleep quality. Subgroup analysis showed that inhalation aromatherapy was more effective than aromatherapy applied via massage.
The authors concluded that readily available aromatherapy treatments appear to be effective and promote sleep. Thus, it is essential to develop specific guidelines for the efficient use of aromatherapy.
Perfect! Let’s all rush out and get some essential oils for inhalation to improve our sleep (remarkably, the results imply that aroma therapists are redundant!).
Not so fast! As I see it, there are several important caveats we might want to consider before spending our money this way:
- Why did this review focus on such a small time-frame? (Systematic reviews should include all the available evidence of a pre-defined quality.)
- The quality of the included studies was often very poor, and therefore the overall conclusion cannot be definitive.
- The effect size of armoatherapy is small. In 2000, we published a similar review and concluded that aromatherapy has a mild, transient anxiolytic effect. Based on a critical assessment of the six studies relating to relaxation, the effects of aromatherapy are probably not strong enough for it to be considered for the treatment of anxiety. The hypothesis that it is effective for any other indication is not supported by the findings of rigorous clinical trials.
- It seems uncertain which essential oil is best suited for this indication.
- Aromatherapy is not always entirely free of risks. Another of our reviews showed that aromatherapy has the potential to cause adverse effects some of which are serious. Their frequency remains unknown. Lack of sufficiently convincing evidence regarding the effectiveness of aromatherapy combined with its potential to cause adverse effects questions the usefulness of this modality in any condition.
- There are several effective ways for improving sleep when needed; we need to know how aromatherapy compares to established treatments for that indication.
All in all, I think stronger evidence is required that aromatherapy is more that pampering.
According to Bloomberg Markets, A Nelson & Co Ltd. manufactures and markets natural healthcare products. The company offers arnica creams that provide natural first aid for bruises; plant and flower based remedies that help in managing the emotional demands of everyday life; and over-the-counter homeopathic medicines for everyday ailments, such as relief from travel sickness and relief for the symptoms of hay fever. It also provides hemorrhoid relief creams and soothing hygienic wipes; anti-blemish range products for various skin types and age groups; multi-purpose cream that helps to soothe and restore skin; iron supplements; teething granules that provide relief from the symptoms and discomfort of teething; a range of creams, ointments, and sprays for a range of common skin conditions/complaints; and a range of commonly used herbal remedies. The company offers products for ailments, including aches and pains, mild anxiety, babies and children, colds and minor infections, digestion, emotional health, energy, everyday stresses, first aid, getting older, pets, quit smoking, skin, sleep, travel, and women’s health. It also operates a clinic; and a pharmacy that offers homeopathy and complementary healthcare products. The company offers its products through its pharmacy in the United Kingdom; and distributors in Europe, Latin America, and internationally. It also serves customers online. The company was formerly known as Armbrecht, Nelson & Co. The company was founded in 1860 and is based in London, United Kingdom with subsidiary offices in Boston, Massachusetts; and Hamburg, Germany. A Nelson & Co Ltd. operates as a subsidiary of Nelson and Russell Holdings Ltd.
In the journal ‘Chemist and Druggist’ we find an article informing us that, in 1930, Nelsons Homeopathic Pharmacy was approached by Dr Edward Bach who wanted help making and selling his products. He had created 38 flower remedies to rebalance emotions and later created an emergency remedy, a combination of five flower remedies that became Rescue. The relationship between Nelsons and the Dr Edward Bach Centre, based at Dr Bach’s former home at Mount Vernon in Oxfordshire, continues to this day and both the Bach Original Flower Remedies and Rescue are key ranges for Nelsons.
Nelson’s homeopathic pharmacy has a proud history:
Ernst Louis Armbrecht, a German pharmacist and disciple of Samuel Hahnemann, came to London and founded Nelsonsin 1860. Since then, Nelsons has been supplying homeopathic medicines. “Our wish today” they state “is the same as 152 years ago: to make homeopathy accessible and to provide the highest standards of medicine and advice.”
The highest standards of medicine and advice? It seems that the Advertising Standards Authority (ASA) disagrees. A recent ASA Adjudication on A Nelson & Co Ltd deals with an advertisement by Nelsons for ‘Bach Rescue Night’ which stated “I CAN’T SWITCH OFF…The RESCUE NIGHT range helps your mind switch off, so you can enjoy a natural night’s sleep”
A freelance health writer had challenged whether the claims “I can’t switch off … Rescue Night range helps your mind switch off, so you can enjoy a natural night’s sleep” was an authorised health claim in the EU Register of Nutrition and Health Claims for Foods (the EU Register).
The ASA noted that, according to EC Regulation 1924/2006 on Nutrition and Health Claims made on Foods (the Regulation), which was reflected in the CAP Code, only health claims which appeared on the list of authorised health claims (the Register) could be made in ads promoting foods, including food supplements. Health claims were defined as those that stated, suggested or implied that a relationship existed between a food category, a food or one of its constituents and health.
The ASA furthermore stated: We acknowledged Rescue Remedy’s assertion that their ad had not made specific claims to aid sleep or that it improved sleep. However, we considered that the use of visuals such as a crescent moon and stars on a dark background, that the letter ‘O’ in the word “OFF” resembled a simple on/ off light switch image, the text “… you can enjoy a natural night’s sleep” and the name of the product “Rescue Night” was likely to give the impression to consumers that it was a product that would aid sleep or that it would help consumers fall asleep easily. We understood that ‘unwanted thoughts’ was one reason why consumers might find it difficult to get to sleep and, again, considered this added to the impression that the product would contribute positively to sleep. We therefore considered that the ad made a health claim related to sleep involving a food item.
We understood that some Bach Flower Remedies contained levels of alcohol which would preclude them from bearing health claims altogether, however, we noted that Bach Rescue Night was alcohol free. We acknowledged Rescue Remedy’s points regarding EFSA and ‘on hold’ claims for botanicals. We understood that ‘on hold’ claims for such botanicals could be used in marketing, provided such use had the same meaning as the proposed claim and they were used in compliance with applicable existing national provisions (in this case the CAP Code). However, Rescue Remedy did not provide evidence that relevant proposed claims for white chestnut, or any of the other product ingredients were ‘on hold’. Nevertheless, we understood that there were no ‘on hold’ claims entered onto the Register for white chestnut or the other product ingredients. Furthermore, ‘on hold’ claims should also be supported with adequate substantiation which we did not receive.
Because the ad made health claims relating to Bach Rescue Night as a sleep aid and we had not seen evidence that relevant claims for the botanical ingredients contained in the product were ‘on hold’, we concluded that the ad breached the Code.
The ad breached CAP Code (Edition 12) rules 15.1, 15.1.1 and 15.7 (Food, food supplements and associated health or nutritional claims).
The ASA ruled that the ad must not appear again in its current form. We told A Nelson & Co Ltd t/a rescueremedy.co.uk not to make health claims for botanical ingredients if they did not comply with the requirements of the Regulation.
I am afraid that such a ruling will have very little effect on the sale of Bach Flower Remedies. In case you have any doubt, I should mention that these inventions of Dr Bach are not supported by good evidence. Here is the abstract of my systematic review on the subject:
Bach flower remedies continue to be popular and its proponents make a range of medicinal claims for them. The aim of this systematic review was to critically evaluate the evidence for these claims. Five electronic databases were searched without restrictions on time or language. All randomised clinical trials of flower remedies were included. Seven such studies were located. All but one were placebo-controlled. All placebo-controlled trials failed to demonstrate efficacy. It is concluded that the most reliable clinical trials do not show any differences between flower remedies and placebos.
Bach Flower Remedies have no effect whatsoever!
Come to think of it, this is not entirely true: they obviously keep the ASA busy, they exploit the gullible public, and they are clearly good for the cash flow at Nelson’s.
Poor sleep quality during pregnancy is a frequent problem. Drug treatment can be problematic due to possible adverse effects for mother and embryo/foetus. Many pregnant women prefer natural treatments and assume that ‘natural’ equals harmless.
In the present study, the sedative effects of Bryophyllum pinnatum were investigated. This remedy is a phytotherapeutic medication predominantly used in anthroposophic medicine. In previous clinical studies on its tocolytic effect, B. pinnatum showed a promising risk/benefit ratio for mother and child. A recent analysis of the prescribing pattern for B. pinnatum in a network of anthroposophic physicians revealed sleep disorders as one of the most frequent diagnosis.
In this prospective, multi-centre, observational study, pregnant women suffering from sleep problems were treated with B. pinnatum (350mg tablets, 50% leaf press juice, Weleda AG, Arlesheim, dosage at physician’s consideration). Sleep quality, daily sleepiness and fatigue were assessed with the aid of standardised questionnaires, at the beginning of the treatment and after 2 weeks. Possible adverse effects perceived by the patients during the treatment were recorded.
The results show that the number of wake-ups, as well as the subjective quality of sleep was significantly improved at the end of the treatment with B. pinnatum. The Epworth Sleeping Scale decreased, indicating a reduction in tiredness during the day. There was, however, no evidence for a prolongation of the sleep duration, reduction in the time to fall asleep, as well as change in the Fatigue Severity Scale after B. pinnatum. No serious adverse drug reactions were detected.
From these data, the authors concluded that B. pinnatum is a suitable treatment of sleep problems in pregnancy. The data of this study encourage further clinical investigations on the use of B. pinnatum in sleep disorders.
Clinical trials of anthroposophic remedies, i.e. remedies which are based on the school of medicine founded by Rudolf Steiner, are very rare. Therefore this trial could be important.
B. pinnatum is a plant used in traditional Tai medicine against hypertension, and to some extend this makes sense: it contains cardiac glycosides which might help lowering elevated blood pressure. The reason for its use as a hypnotic, however, is not clear.
So, is B pinnatum really a ‘suitable treatment of sleep problems in pregnancy’? I doubt it for the following reasons:
- the effects documented in this study are far from convincing,
- we would need much more solid data to issue such a general recommendation,
- cardiac glycosides can cause very serious adverse effects,
- the sample size of the study is at least one dimension too small for assuming that it is safe,
- we know nothing about its potential to cause harm to the foetus.
Personally, I find it irresponsible to draw conclusions such as the ones above on the basis of data which are flimsy to the extreme. I ask myself, to what extend wishful thinking might be a regrettable characteristic for the entire field of anthroposophic medicine.
Since weeks I have been searching for new (2013) studies which actually report POSITIVE results. I like good news as much as the next man but, in my line of business, it seems awfully hard to come by. Therefore I am all the more delighted to present these two new articles to my readers.
The first study is a randomized trial with patients suffering from metastatic cancer who received one of three interventions: massage therapy, no-touch intervention or usual care. Primary outcomes were pain, anxiety, and alertness; secondary outcomes were quality of life and sleep. The mean number of massage therapy sessions per patient was 2.8.
The results show significant improvement in the quality of life of the patients who received massage therapy after 1-week follow-up which was not observed in either of the other groups. Unfortunately, the difference was not sustained at 1 month. There were also trends towards improvement in pain and sleep of the patients after massage. No serious adverse events were noted.
The authors conclude that “providing therapeutic massage improves the quality of life at the end of life for patients and may be associated with further beneficial effects, such as improvement in pain and sleep quality. Larger randomized controlled trials are needed to substantiate these findings“.
The second study examined the effectiveness of a back massage for improving sleep quality in 60 postpartum women suffering from poor sleep. They were randomized to either the intervention or the control group. Participants in both groups received the same care except for the back massages. The intervention group received one 20-minutes back massage at the same time each evening for 5 consecutive days by a certified massage therapist. The outcome measure was the Pittsburgh Sleep Quality Index (PSQI). The results showed that the changes in mean PSQI were significantly lower in the intervention group than in controls indicating a positive effect of massage on sleep quality.
The authors’ conclusions were clear: “an intervention involving back massage in the postnatal period significantly improved the quality of sleep.”
Where I was trained (Germany), massage is not deemed to be an alternative but an entirely mainstream treatment. Despite this fact, there is precious little evidence to demonstrate that it is effective. Our own research has found encouraging evidence for a range of conditions, including autism, cancer palliation, constipation, DOMS and back pain. In addition, we have shown that massage is not entirely free of risks but that its potential for harm is very low (some might say that this was never in question but it is good to have a bit more solid evidence).
The new studies are, of course, not without flaws; this can hardly be expected in an area where logistical, financial and methodological problems abound. The fact that there are many different approaches to massage does not make things easier either. The new evidence is nevertheless encouraging and seems to suggest that massage has relaxing effects which are clinically relevant. In my view, massage is a therapy worth considering for more rigorous research.
