Yes, I know, lately I have been neglecting my ‘ALT MED HALL OF FAME’. This is entirely my fault; there are so many candidates waiting to be admitted that, I have been hesitant as to who should be next. Today, I came across an article about Deepak Chopra and his latest book, Super Genes. It tells “how lifestyle shifts can help you reboot your health at a genetic level.” If it were just for this single sentence, he would deserve to be admitted – no, not into what you just thought, into the ‘ALT MED HALL OF FAME’, of course’.
I will save you the expense of buying his book (don’t worry, Deepak is already a multi-millionaire) by repeating what the article said about his ‘6 pillars of wellbeing’ (another cracker!!!):
• A typical modern diet is very likely to cause inflammation, which research has linked to many chronic diseases and obesity.
• To reduce inflammation, add prebiotics – substances that buffer the body from inflammation – such as oatmeal, pulpy orange juice, bran cereal and bananas to your breakfast.
• Consume probiotics – foods that contain active bacteria – once a day for gut health. These foods include active yoghurt, pickles and sauerkraut.
• Eat mindfully – eat only when you’re genuinely hungry and stop when you are full.
• Reduce snacking by eating only one measured portion in a bowl; never eat straight from a bag or packet.
• Three factors generally lie behind the problem of chronic stress: repetition, unpredictability and a lack of control. Think of a dog barking outside your window; you don’t know when it will end and you have no way of stopping it.
• Decrease background noise and distractions at work. Also, avoid multitasking by dealing with one thing at a time.
• Leave work on time at least three times a week and don’t bring work home. Leave the office at the office.
• Avoid people who are sources of pressure and conflict. Even normal office behaviour, such as forming cliques and gossiping, is a source of stress that has the potential to be emotionally devastating.
• If you struggle to deal with negative emotions, ask your doctor about cognitive behaviour therapy.
• The secret to exercise is this: keep going and don’t stop. It’s better to be active all your life at a lower level, rather than to be at a near professional-level in high school, say, and then stop completely.
• At work get up and move around once an hour and devote half your lunch break to movement, even if it’s walking around the block.
• Be in nature more: go outside for five to 10 minutes three times a day.
• Acquire more active friends and join them in their activities. Plan a shared exercise activity with your spouse or friends twice a week.
• Make leisure time more creative – think beyond TV or internet.
• Volunteer to help the needy with housecleaning, painting and repairs.
This will serve as both exercise and a morale boost.
• Meditate every day for 10 minutes.
Sit with your eyes closed in a quiet place, put your attention on the tip of your nose and focus on the sensation of your breath coming in and out of your nostrils.
• Don’t look at meditation as an aid for the bad days you experience (“I’m feeling good today, so I don’t need to meditate”). It should be a lifelong practice.
• Take 10 minutes out of your lunch break to sit alone with eyes closed, preferably outside in nature.
• Notice what a relief it is to take big deep breaths when you are upset or nervous, and how ragged your breath becomes when you are anxious or stressed.
• Join an organised meditation course in your area. Search for meetup.com to find local groups that meet all around the country.
• Make your bedroom as dark as possible. If total darkness is impossible, wear a sleep mask.
• Drink a glass of warm almond milk, which is rich in calcium and promotes melatonin, a hormone that helps to regulate the sleep-wake cycle.
• Experiment with herbal teas associated with good sleep such as chamomile, valerian, passionflower, lavender and kava kava.
• Explore abhyanga, a self-massage technique that uses warmed sesame oil, lightly massaged into arms, legs, neck and torso (go to YouTube to see tutorials).
• Don’t ignore insomnia. In some studies sleep disorders have been associated with triggering Alzheimer’s disease and are also associated with high blood pressure.
• Take responsibility for your feelings. Wellbeing depends upon happiness, yet most people don’t really make that connection.
• Write down five specific things that make you happy and, on a daily basis, do at least one of them.
• Set a “good news policy” at meal times, whether it’s the radio station you choose to listen to or the topic of conversation around the table.
• Explore a time in your past when you were happy and learn from it, whether that means re-embracing an old hobby or getting in touch with an old friend.
• Become comfortable with delayed gratification – consider how your choices will make you feel in the future as well as today.
END OF QUOTE
My favourite website about Deepak Chopra is the one by Tom Williamson. It states that “it has been said by some that the thoughts and tweets of Deepak Chopra are indistinguishable from a set of profound sounding words put together in a random order, particularly the tweets tagged with “#cosmisconciousness”. This site aims to test that claim! Each “quote” is generated from a list of words that can be found in Deepak Chopra’s Twitter stream randomly stuck together in a sentence.” It seems to me that Deepak himself might have made ample use of this site for writing his latest book, and if you should ever run out of platitudes or empty phrases, this site will serve you well.
Deepak has published plenty of best-sellers, but he has as good as nothing to show for himself in the peer-reviewed medical literature. (When you are that famous, you obviously don’t need to bother anymore with trivia such as evidence, science and all that jazz.) This means that I had to deviate from my usual admission criteria for the “prophet of alternative medicine”, as Deepak likes to be called. But he is well worth making an exception, I am sure you agree, he is the absolute super-star!
Super-star of what?
I let you decide!
On this blog, I have repeatedly pleaded for a change of the 2010 NICE guidelines for low back pain (LBP). My reason was that it had become quite clear that their recommendation to use spinal manipulation and acupuncture for recurrent LBP was no longer supported by sound evidence.
Two years ago, a systematic review (authored by a chiropractor and published in a chiro-journal) concluded that “there is no conclusive evidence that clearly favours spinal manipulation or exercise as more effective in treatment of CLBP.” A the time, I wrote a blog explaining that “whenever two treatments are equally effective (or, in this case, perhaps equally ineffective?), we must consider other important criteria such as safety and cost. Regular chiropractic care (chiropractors use spinal manipulation on almost every patient, while osteopaths and physiotherapists employ it less frequently) is neither cheap nor free of serious adverse effects such as strokes; regular exercise has none of these disadvantages. In view of these undeniable facts, it is hard not to come up with anything other than the following recommendation: until new and compelling evidence becomes available, exercise ought to be preferred over spinal manipulation as a treatment of chronic LBP – and consequently consulting a chiropractor should not be the first choice for chronic LBP patients.”
Three years ago, a systematic review of acupuncture for LBP (published in a TCM-journal) concluded that the effect of acupuncture “is likely to be produced by the nonspecific effects of manipulation.” At that time I concluded my blog-post with this question: Should NICE be recommending placebo-treatments and have the tax payer foot the bill? Now NICE have provided an answer.
The new draft guideline by NICE recommends various forms of exercise as the first step in managing low back pain. Massage and manipulation by a physiotherapist should only be used alongside exercise; there is not enough evidence to show they are of benefit when used alone. Moreover, patients should be encouraged to continue with normal activities as far as possible. Crucially, the draft guideline no longer recommends acupuncture for treating low back pain.
NICE concluded that the evidence shows that acupuncture is not better than sham treatment. Paracetamol on its own is no longer recommended either, instead non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or aspirin should be tried first. Talking therapies are recommended in combination with physical therapies for patients who had no improvement on previous treatments or who have significant psychological and social barriers to recovery.
Professor Mark Baker, clinical practice director for NICE, was quoted stating “Regrettably there is a lack of convincing evidence of effectiveness for some widely used treatments. For example acupuncture is no longer recommended for managing low back pain with or without sciatica. This is because there is not enough evidence to show that it is more effective than sham treatment.”
Good news for us all, I would say:
- good news for patients who now hear from an accepted authority what to do when they suffer from LBP,
- good news for society who does no longer need to spend vast amounts of money on questionable therapies,
- good news for responsible clinicians who now have clear guidance which they can show and explain to their patients.
Not so good news, I admit, for acupuncturists, chiropractors and osteopaths who just had a major source of their income scrapped. I have tried to find some first reactions from these groups but, for the moment, they seemed to be stunned into silence – nobody seems to have yet objected to the new guideline. Instead, I found a very recent website where chiropractic is not just recommended for LBP therapy but where patients are instructed that, even in the absence of pain, they need to see their chiropractor regularly: “Maintenance chiropractic care is well supported in studies for controlling chronic LBP.”
NEVER LET THE TRUTH GET IN THE WAY OF YOUR CASH-FLOW…they seem to conclude.
Chronic pain is a common and serious problem for many patients. Treatment often includes non-pharmacological approaches despite the mostly flimsy evidence to support them. The objective of this study was to measure the feasibility and efficacy of hypnosis (including self-hypnosis) in the management of chronic pain in older hospitalized patients.
A single center randomized controlled trial using a two arm parallel group design (hypnosis versus massage). Inclusion criteria were chronic pain for more than 3 months with impact on daily life activities, intensity of > 4; adapted analgesic treatment; no cognitive impairment. Fifty-three patients were included. Pain intensity decreased significantly in both groups after each session. Average pain measured by the brief pain index sustained a greater decrease in the hypnosis group compared to the massage group during the hospitalization. This was confirmed by the measure of intensity of the pain before each session that decreased only in the hypnosis group over time. Depression scores improved significantly over the time only in the hypnosis group. There was no effect in either group 3 months post hospitals discharge.
The authors concluded that hypnosis represents a safe and valuable tool in chronic pain management of hospitalized older patients. In hospital interventions did not provide long-term post discharge relief.
So, hypnotherapy is better than massage therapy when administered as an adjunct to conventional pain management. As it is difficult to control for placebo effects, which might be substantial in this case, we cannot be sure whether hypnotherapy per se was effective or not.
Who cares? The main thing is to make life easier for these poor patients!
There are situations where I tend to agree with this slightly unscientific but compassionate point of view. Yes, the evidence is flimsy, but we need to help these patients. Hypnotherapy has very few risks, is relatively inexpensive and might help badly suffering individuals. In this case, does it really matter whether the benefit was mediated by a specific or a non-specific mechanism?
Being constantly on the look-out for new, good quality articles on alternative therapy which suggest that a treatment might actually work, I was excited to find not just one or two but four recent publications on an old favourite of mine: massage therapy.
The first paper described a study aimed to investigate the effect of whole body massage on the vital signs, Glasgow Coma Scale (GCS) scores and arterial blood gases (ABG) in trauma ICU patients.
In a randomized, double-blind trial, 108 trauma ICU patients received whole body massage or routine care only. The patients vital signs; systolic blood pressure (SBP), diastolic blood pressure (DBP), respiratory rate (RR), pulse rate (PR), Temperature (T), GCS score and ABG parameters were measured in both groups before the intervention and 1 hour and 3 hours after the intervention. The patient in experimental group received full body massage in 45 minute by a family member.
Significant differences were observed between experimental and control groups in SBP 1 hour and 3 hours after intervention, DBP, RR and PR 1 hour after intervention, and GCS 1 hour and 3 hours after intervention. Significant differences were also observed between experimental and control groups in O2 saturation, PH and pO2. No significant differences between experimental and control groups were noted in Temperature, pCO2 and HCO3.
The authors concluded that massage therapy is a safe and effective treatment in intensive care units to reduce patient’s physical and psychological problems. Therefore the use of massage therapy is recommended to clinical practice as a routine method.
The second paper reported a clinical trial on 66 male and female nurses working in intensive care units of Isfahan University of Medical Sciences, Iran.
Patients were randomly divided into experimental and control groups. The Occupational Stress Inventory (OSI) (Osipow and Spokane, 1987) was completed by participants of the two groups before, immediately after, and 2 weeks after the intervention. Swedish massage was performed on participants of the experimental group for 25 min in each session, twice a week for 4 weeks.
Results showed a significant difference in favour of the massage therapy in overall mean occupation stress scores between experimental and control groups two weeks after the intervention.
The authors concluded that it is recommended that massage, as a valuable noninvasive method, be used for nurses in intensive care units to reduce their stress, promote mental health, and prevent the decrease in quality of nursing work life.
The third paper described a randomized controlled trial evaluating the effects of post-operative massage in patients undergoing abdominal colorectal surgery.
One hundred twenty-seven patients were randomized to receive a 20-min massage or social visit and relaxation session on postoperative days 2 and 3. Vital signs and psychological well-being (pain, tension, anxiety, satisfaction with care, relaxation) were assessed before and after each intervention.
Post-operative massage significantly improved the patients’ perception of pain, tension, and anxiety, but overall satisfaction was unchanged.
The authors concluded that massage may be beneficial during postoperative recovery for patients undergoing abdominal colorectal surgery. Further studies are warranted to optimize timing and duration and to determine other benefits in this clinical setting.
The fourth paper reported a systematic review was to evaluate the effectiveness of massage on the short- and long-term outcomes of pre-term infants.
Literature searches were conducted using the PRISMA framework. Validity of included studies was assessed using criteria defined by the Cochrane Collaboration. Assessments were carried out independently by two reviewers with a third reviewer to resolve differences.
Thirty-four studies met the inclusion criteria, 3 were quasi-experimental, 1 was a pilot study, and the remaining 30 were RCTs. The outcomes that could be used in the meta-analysis and found in more than three studies suggested that massage improved daily weight gain by 0.53 g, and resulted in a significant improvement in mental scores by 7.89 points. There were no significant effects on length of hospital stay, caloric intake, or weight at discharge. Other outcomes were not analyzed either because the units of measurement varied between studies, or because means and standard deviations were not provided by the authors. The quality of the studies was variable with methods of randomization and blinding of assessment unclear in 18 of the 34 trials.
The authors concluded that massage therapy could be a comforting measure for infants in the NICU to improve weight gain and enhance mental development. However, the high heterogeneity, the weak quality in some studies, and the lack of a scientific association between massage and developmental outcomes preclude making definite recommendations and highlight the need for further RCTs to contribute to the existing body of knowledge.
I am not saying that these articles are flawless, nor that I agree with all of their conclusion. What I am trying to indicate is that we finally have here an alternative therapy that is promising.
When I worked in Germany and later in Austria, massage was considered to be entirely mainstream. It was only after I had moved to the UK when I realised that, in English-speaking countries, it is mostly considered to be alternative. Perhaps this classification is wrong?
Perhaps we should differentiate according to what type of massage we are talking about. In the realm of alternative medicine – and not just there, I suppose – this seems good advice indeed.
The above papers are about classical massage therapy, but there are some types pf massage which are less than conventional: aura-massage, Marma massage, Indian head massage, shiatsu etc. etc. the list seems endless. These are alternative in more than one sense, and they have one thing in common: there is, as far as I can see, no good evidence to show that they do anything to human health.
My conclusion therefore is that, even with something as common as massage therapy, we need to be careful not to be roped in by the charlatans.
A reader of this blog recently sent me the following message: “Looks like this group followed you recent post about how to perform a CAM RCT!” A link directed me to a new trial of ear-acupressure. Today is ‘national acupuncture and oriental medicine day’ in the US, a good occasion perhaps to have a critical look at it.
The aim of this study was to assess the effectiveness of ear acupressure and massage vs. control in the improvement of pain, anxiety and depression in persons diagnosed with dementia.
For this purpose, the researchers recruited a total of 120 elderly dementia patients institutionalized in residential homes. The participants were randomly allocated, to three groups:
- Control group – they continued with their routine activities;
- Ear acupressure intervention group – they received ear acupressure treatment (pressure was applied to acupressure points on the ear);
- Massage therapy intervention group – they received relaxing massage therapy.
Pain, anxiety and depression were assessed with the Doloplus2, Cornell and Campbell scales. The study was carried out during 5 months; three months of experimental treatment and two months with no treatment. The assessments were done at baseline, each month during the treatment and at one and two months of follow-up.
A total of 111 participants completed the study. The ear acupressure intervention group showed better improvements than the two other groups in relation to pain and depression during the treatment period and at one month of follow-up. The best improvement in pain was achieved in the last (3rd) month of ear acupressure treatment. The best results regarding anxiety were also observed in the last month of treatment.
The authors concluded that ear acupressure and massage therapy showed better results than the control group in relation to pain, anxiety and depression. However, ear acupressure achieved more improvements.
The question is: IS THIS A RIGOROUS TRIAL?
My answer would be NO.
Now I better explain why, don’t I?
If we look at them critically, the results of this trial might merely prove that spending some time with a patient, being nice to her, administering a treatment that involves time and touch, etc. yields positive changes in subjective experiences of pain, anxiety and depression. Thus the results of this study might have nothing to do with the therapies per se.
And why would acupressure be more successful than massage therapy? Massage therapy is an ‘old hat’ for many patients; by contrast, acupressure is exotic and relates to mystical life forces etc. Features like that have the potential to maximise the placebo-response. Therefore it is conceivable that they have contributed to the superiority of acupressure over massage.
What I am saying is that the results of this trial can be interpreted in not just one but several ways. The main reason for that is the fact that the control group were not given an acceptable placebo, one that was indistinguishable from the real treatment. Patients were fully aware of what type of intervention they were getting. Therefore their expectations, possibly heightened by the therapists, determined the outcomes. Consequently there were factors at work which were totally beyond the control of the researchers and a clear causal link between the therapy and the outcome cannot be established.
An RCT that is aimed to test the effectiveness of a therapy but fails to establish such a causal link beyond reasonable doubt cannot be characterised as a rigorous study, I am afraid.
Sorry! Did I spoil your ‘national acupuncture and oriental medicine day’?
What is the best treatment for the millions of people who suffer from chronic low back pain (CLBP)? If we are honest, no therapy has yet been proven to be overwhelmingly effective. Whenever something like that happens in medicine, we have a proliferation of interventions which all are promoted as effective but which, in fact, work just marginally. And sure enough, in the case of CLBP, we have a constantly growing list of treatments none of which is really convincing.
One of the latest additions to this list is PILATES.
Pilates? What is this ? One practitioner describes it as follows: In Pilates, we pay a lot of attention to how our body parts are lined up in relation to each other, which is our alignment. We usually think of our alignment as our posture, but good posture is a dynamic process, dependent on the body’s ability to align its parts to respond to varying demands effectively. When alignment is off, uneven stresses on the skeleton, especially the spine, are the result. Pilates exercises, done with attention to alignment, create uniform muscle use and development, allowing movement to flow through the body in a natural way.
For example, one of the most common postural imbalances that people have is the tendency to either tuck or tilt the pelvis. Both positions create weaknesses on one side of the body and overly tight areas on the other. They deny the spine the support of its natural curves and create a domino effect of aches and pains all the way up the spine and into the neck. Doing Pilates increases the awareness of the proper placement of the spine and pelvis, and creates the inner strength to support the natural curves of the spine. This is called having a neutral spine and it has been the key to better backs for many people.
Mumbo-jumbo? Perhaps; in any case, we need evidence! Is there any at all? Surprisingly, the answer is yes. Recently, someone even published a proper systematic review.
This systematic review was aimed at evaluating the effectiveness of Pilates exercise in people with chronic low back pain (CLBP).
A search for RCTs was undertaken in 10 electronic. Two independent reviewers did the selection of evidence and evaluated the quality of the primary studies. To be included, relevant RCTs needed to be published in the English language. From 152 studies, 14 RCTs could be included.
The methodological quality of RCTs ranged from “poor” to “excellent”. A meta-analysis of RCTs was not undertaken due to the heterogeneity of RCTs. Pilates exercise provided statistically significant improvements in pain and functional ability compared to usual care and physical activity between 4 and 15 weeks, but not at 24 weeks. There were no consistent statistically significant differences in improvements in pain and functional ability with Pilates exercise, massage therapy, or other forms of exercise at any time period.
The authors drew the following conclusions: Pilates exercise offers greater improvements in pain and functional ability compared to usual care and physical activity in the short term. Pilates exercise offers equivalent improvements to massage therapy and other forms of exercise. Future research should explore optimal Pilates exercise designs, and whether some people with CLBP may benefit from Pilates exercise more than others.
So, Pilates can be added to the long list of treatments that work for CLBP, albeit not convincingly better than most other therapies on offer. Does that mean these options are all as good or as bad as the next? I don’t think so.
Let’s assume chiropractic/osteopathic manipulations, massage and various forms of exercise are all equally effective. How do we decide which is more commendable than the next? We clearly need to take other important factors into account:
- acceptability for patients
If we use these criteria, it becomes instantly clear that chiropractic and osteopathy are not favourites in this race for the most commendable CLBP-treatment. They are neither cheap nor free of risks. Massage is virtually risk-free but not cheap. This leaves us with various forms of exercise, including Pilates. But which exercise is better than the next? At present, we do not know, and therefore the last two factors are crucial: if people love doing Pilates and if they easily stick with it, then Pilates is fine.
I am sure chiropractors will (yet again) disagree with me but, to me, this logic could hardly be more straight forward.
Chronic neck pain is common and makes the life of many sufferers a misery. Pain-killers are helpful, of course, but who wants to take such medications on the long-term? Is there anything else these patients can do?
Massage therapy has been shown to work but how often for how long? This trial was designed to evaluate the optimal dose of massage for individuals with chronic neck pain. 228 individuals with chronic non-specific neck pain were recruited and randomized them to 5 groups receiving various doses of massage:
- 30-minute treatments 2 or 3 times weekly
- 60-minute treatments once weekly
- 60-minutte treatments twice weekly
- 60-minute treatments thrice weekly
- a 4-week period on a wait list
Neck-related dysfunction was assessed with the Neck Disability Index (range, 0-50 points) and pain intensity with a numerical rating scale (range, 0-10 points) at baseline and at 5 weeks.
The results suggested that 30-minute treatments were not significantly better than the waiting list control condition in terms of achieving a clinically meaningful improvement in neck dysfunction or pain, regardless of the frequency of treatments. In contrast, 60-minute treatments 2 and 3 times weekly significantly increased the likelihood of such improvement compared with the control condition in terms of both neck dysfunction and pain intensity.
The authors conclude that after 4 weeks of treatment, we found multiple 60-minute massages per week more effective than fewer or shorter sessions for individuals with chronic neck pain. Clinicians recommending massage and researchers studying this therapy should ensure that patients receive a likely effective dose of treatment.
So two or three hours of massage therapy seems to be optimal as a treatment for chronic neck pain. This would cost ~£ 200-300 per week! Who can or wants to afford this? And are there other options that might be less expensive and equally or more effective? For instance, is physiotherapeutic exercise an option?
I am not sure I know the answers to these questions but, before we recommend massage therapy to the many who chronically suffer from neck pain, we should find out.
Fibromyalgia (FM) is a chronic condition which ruins the quality of life of many patients. It is also a domain of alternative medicine: dozens of different treatments are on offer – this is clearly a paradise for charlatans and bogus claims. So is there a treatment that is demonstrably effective? The purpose of this systematic review is to evaluate the evidence of massage therapy FM.
Electronic databases were searched to identify relevant studies. The main outcome measures were pain, anxiety, depression, and sleep disturbance. Two reviewers independently abstracted data and appraised risk of bias. The risk of bias of eligible studies was assessed based on Cochrane tools.
Nine randomized controlled trials involving 404 patients met the inclusion criteria. A meta-analyses showed that massage therapy with a duration of at least 5 weeks significantly improved pain , anxiety, and depression. Sleep disturbance was not improved by massage therapy.
The authors conclude that massage therapy with duration ≥5 weeks had beneficial immediate effects on improving pain, anxiety, and depression in patients with FM. Massage therapy should be one of the viable complementary and alternative treatments for FM. However, given fewer eligible studies in subgroup meta-analyses and no evidence on follow-up effects, large-scale randomized controlled trials with long follow-up are warrant to confirm the current findings.
To put these results into context, we need to consider the often poor methodological quality of the primary studies. It is, of course, not easy to test massage therapy in rigorous trials. For instance, there is no obvious placebo, and we can therefore not be sure whether the treatment benefits patients through a specific effect or whether non-specific effects are the cause of the improvement.
We also should be aware of the facts that for most other alternative therapies the evidence is not encouraging, and that massage therapy is relatively safe. Therefore the conclusion for those who suffer from FM might well be that massage therapy is worth a try.
Researchers from the ‘International Centre for Allied Health Evidence’, University of South Australia in Adelaide wanted to determine whether massage therapy is an effective intervention for back pain. They carried out extensive literature searches to identify all systematic reviews on the subject, analysed them critically and evaluated their methodological quality. Nine systematic reviews were found. Their methodological quality varied from poor to excellent. The primary research informing these systematic reviews was generally considered to be weak quality. The findings indicated that massage may be an effective treatment option when compared to placebo or active treatment options such as relaxation, especially in the short term. There were conflicting and contradictory findings for the effectiveness of massage therapy as a treatment of non-specific low back pain when compared against other manual therapies such as mobilization, standard medical care, and acupuncture.
The authors concluded that there is an emerging body of evidence, albeit small, that supports the effectiveness of massage therapy for the treatment of non-specific low back pain in the short term. Due to common methodological flaws in the primary research, which informed the systematic reviews recommendations arising from this evidence base should be interpreted with caution.
My own systematic review from 1999 (which the authors of this systematic review of systematic reviews seem to have missed) concluded that massage seems to have some potential as a therapy for low back pain. Indeed, there seems to be unanimous agreement that massage therapy is a promising treatment. Why then do massage therapists not finally get their act together and conduct a few more high quality primary studies? Currently, we have about as many reviews as trials! Doing even more reviews will not answer the question about effectiveness!!!
And it is a damn important question. Back pain is extremely common and extremely expensive for us all. At present, we have no optimal treatment. Chiropractors and osteopaths are claiming to have found a good solution, but many experts are not convinced by their evidence and argue that the risks of spinal manipulation might not outweigh its benefits. Massage, by contrast, is almost risk-free. Considering all this, I believe we need more trials with some urgency.
So, why are such trials not forthcoming? I realise that multiple hurdles have to be taken:
- Clinical studies of that nature are expensive, and there is no obvious funding source.
- Massage therapists usually do not have enough research expertise to pull off a sound study.
- There are multiple methodological problems in conduction a definitive massage trial that might convince us all.
However, none of these obstacles are insurmountable. I suggest massage therapists team up with experts who know how to run clinical trials, hammer out a reasonable study design and approach government or other official funders for support. We need a definitive answers and we need them soon: is massage effective? which type of massage? for which patients? at which stage of non-specific low back pain?
Massage is an agreeable and pleasant treatment. It comes in various guises and, according to many patients’ experience, it relaxes both the mind and the body. But does it have therapeutic effects which go beyond such alleged benefits?
There is a considerable amount of research to test whether massage is effective for some conditions, including depression. In most instances, the evidence fails to be entirely convincing. Our own systematic review of massage for depression, for instance, concluded that there is currently a lack of evidence.
This was ~5 years ago – but now a new trial has emerged. It was aimed at determining whether massage therapy reduces symptoms of depression in subjects with human immunodeficiency virus (HIV) disease. Subjects were randomized into one of three groups to receive either Swedish massage (the type that is best researched amongst the many massage-variations that exist), or touch, or no such interventions. The treatment period lasted for eight weeks. Patients had to be at least 16 years of age, HIV-positive, suffering from a major depressive disorder, and on a stable neuropsychiatric, analgesic, and antiretroviral regimen for > 30 days with no plans to modify therapy for the duration of the study. Approximately 40% of the subjects were taking antidepressants, and all subjects were judged to be medically stable.
Patients in the Swedish massage and touch groups visited the massage therapist for one hour twice per week. In the touch group, a massage therapist placed both hands on the subject with slight pressure, but no massage, in a uniform distribution in the same pattern used for the massage subjects.
The primary and secondary outcome measures were the Hamilton Rating Scale for Depression score and the Beck Depression Inventory. The results showed that, compared to no intervention and/or touch, massage significantly reduced the severity of depression at week 4, 6 and 8.
The authors’ conclusion is clear: The results indicate that massage therapy can reduce symptoms of depression in subjects with HIV disease. The durability of the response, optimal “dose” of massage, and mechanisms by which massage exerts its antidepressant effects remain to be determined.
Clinical trials of massage therapy encounter formidable problems. No obvious funding source exists, and the expertise to conduct research is minimal within the realm of massage therapy. More importantly, it is difficult to find solutions to the many methodological issues involved in designing rigorous trials of massage therapy.
One such issue is the question of an adequate control intervention which might enable to blind patients and thus account for the effects of placebo, compassion, attention etc. The authors of the present trial have elegantly solved it by creating a type of sham treatment which consisted of mere touch. However, this will only work well, if patients can be made to believe that the sham-intervention was a real treatment, and if somehow the massage therapist is prevented to influence the patients through verbal or non-verbal communications. In the current trial, patients were not blinded, and therefore patients’ expectations may have played a role in influencing the results.
Despite this drawback, the study is one of the more rigorous investigations of massage therapy to date. Its findings offer hope to those patients who suffer from depression and who are desperate for an effective and foremost safe treatment to ease their symptoms.
My conclusion: the question whether massage alleviates depression is intriguing and well worth further study.
