There seems to be increasing advocacy for the use of cannabis oil (medical marijuana) for plantar fasciitis recently, mostly from what I can see, from those who sell it. If you hang out in some of the online communities for those with plantar fasciitis, you see a lot of very bad advice being given, mostly based on anecdotes. In the last year or so, the most popular advice was to use magnesium supplements to cure plantar fasciitis. This was all the rage for a while with an extraordinary number of people advocating its use based on it working for them (when we have no idea if it actually worked or not or if it was just a placebo or just part of the natural history or any other explanation). There is no mechanism that I could find by which it could affect plantar fasciitis. More recently, the volume of advice for the magnesium supplements has started to drop off but is being replaced with an increasing amount of advice for the use of cannabis oil to treat plantar fasciitis. Some of the testimonials are quite compelling … if they are true.Continue reading
When you are busy and have so much important stuff to write about, it is so much easier to go after the ‘low hanging fruit’. Much less effort is needed and when it so easy, you don’t need to think too hard about it. Research on reflexology never fails to deliver on that count.
Reflexology is total bunk; it is made up pseudoscientific bullshit that has no basis what-so-ever. There is absolutely no known physiological mechanism linking areas on the foot to different organ systems and not one clinical trial that stacks up to scrutiny shows that it works. Every single clinical trial on it either shows it does not work or if it shows it works, it has fatal flaws in the methodology (and as such should never have been published, let alone carried out) or more often than not, was not even a clinical trial on reflexology, but a clinical trial on a damn good foot massage. Almost everyone is going to feel better after a damn good foot massage, so measures of anxiety etc are going to improve, especially if a chronic illness is present. Being more relaxed after a damn good foot massage is going to affect a number of psychosocial factors as well as some physiological parameters. BUT, that is not evidence for the junk that is reflexology, that is evidence for a damn good foot massage.
What does apple cider debunking, overpronation and cigarette smoking, Oscon supplements for Severs disease and vaccines causing autism have to do with each other?
^^^ that is the final slide in a video from my Critical Thinking Boot Camp. Anyone who blogs about science always get responses and comments with anecdotes about what was written with responses that it either does or does not apply to them. The science either ‘sucks’ or is the ‘greatest thing since sliced bread’ depending on the anecdote! It has now reached the point where I just delete that anecdotal comments on my posts as they contribute nothing of use to the topic under discussion. Steve Novella succinctly summed this up:
It is almost inevitable that whenever we post an article critical of the claims being made for a particular treatment, alternative philosophy, or alternative profession, someone in the comments will counter a careful examination of published scientific evidence with an anecdote. Their arguments boils down to, “It worked for me, so all of your scientific evidence and plausibility is irrelevant.”
In my other blog, I previously litigated all the issues around “anecdotes” and why useless treatment sometimes appear as though they did work. I don’t intend re-litigating the same issues here but develop them further with some examples I have dealt with recently. For background, I refer you to those two posts.
Health Benefits of Apple Cider
My first example comes from a blog post by Melinda Moyer following an article she wrote on the health benefit of apple cider. These three quotes sum up the issue:
After getting hate mail for debunking the health claims of apple cider vinegar, I’m explaining why I rely on science, not rumors.
Last month, I wrote my first Truth Serum column, “What Apple Cider Vinegar Can—and Can’t—Do for Your Health,” which explored what the science says about apple cider vinegar’s supposed health effects. I found that there isn’t much evidence ACV can cure colds, heal acne, help you lose weight, or alleviate heartburn—and that vinegar can sometimes be harmful.
Then came the angry emails and Facebook posts. Readers chided me for interviewing researchers and doctors rather than people who have actually been helped by apple cider vinegar. Others felt the evidence is irrelevant; vinegar works for them, so they’ll keep using it. A few implied that my writing was unbalanced and unfair.
I am sure you can see the issue …
The whole idea of the peer review process prior to publication is to weed out the junk, so it does not get published. One thing that the alternative therapies have in common is that their journals let a lot of junk science through. Too many studies get published in those journals that should never see the light of day, let alone been conducted so badly in the first place. There are ethical issues at stake in this and the editors of those journals would do well to apprise themselves of publication ethics. Institutional ethics committees or review boards also have a responsibility to prevent bad science from even getting off the ground.
What spurred that little rant was this publication today on ‘The effect of reflexology on the quality of life with breast cancer patients‘ published in the journal, Complementary Therapies in Clinical Practice. They do not get much worse than this one.
It was a study that supposedly randomized 60 people with breast cancer into two groups; one group the control and one group getting reflexology; the aim being to see how it affected their quality of life and symptoms. Sounds good on the surface, but:
One probably should not laugh at another’s misfortune, but sometimes it can just not be helped. For those unfamiliar with it, schadenfreude is the German word for just that. There is not an equivalent English word. I recently, twice, had a really good schadenfreude. This had nothing to do with podiatry or the foot, but has everything to do with pseudoscience and junk science.
This is not foot related, but it is diabetes related and science related.
I have no doubts what-so-ever about climate change and global warming. All the science I have seen is good; the consensus of the overwhelming majority of climate change scientists is good. The only dissent to this overwhelming consensus of experts are those with vested financial interests or those into conspiracy theories who latch on one piece of negative evidence (and ignore the 1000’s of good evidence) or latch onto one dissenting scientist (and ignore the 99.5% of the other scientists). How many more generations that we survive on this planet will depend on how seriously the politicians take this scientific evidence that it is happening.
