Cannabis Oil for Plantar Fasciitis

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.

‘Nocebic Foot Orthotics’ – I invented a new word!

During this morning live broadcast on Facebook of PodChatLive (and its on YouTube) we were discussing paediatric flatfoot and paediatric foot orthoses with Helen Banwell, a question from came in from Marc Barton that got me thinking.

Platelet Rich Plasma for Plantar Fasciitis – writing about something I know nothing about…

Platelet Rich Plasma for Plantar Fasciitis

I have to be honest and admit that the use of platelet rich plasma (PRP) for plantar fasciitis is something that I have had no more than a superficial interest in. I pretty much scanned the abstracts of the studies and systematic reviews as they are published of it in this thread and the one comparing it to other interventions on Podiatry Arena. I also note comments in social media on it from those whose views I respect. From my superficial understanding, it works, it does not work, it works, it does not work … a lot of the studies that compare it to other treatments do not do the “other” treatment very well (ie wrong dosing), which can easily bias the study to PRP being better. Some of the comments in social media from people who I consider real experts, especially in the context of tendinopathy are that it does not work, yet a lot of people claim it does. Yes, I know that the “plantar fasica” is not a “tendon” and it may or may not be appropriate to translate “tendinopathy” research to “plantar fasciitis” (not that this stops people doing so or not doing so if the research on it matches their pre-conceived biases!).

Google Scholar Ranking of Podiatry Journals

Today, Google scholar came out with their 2018 update to their ranking metrics. No point in me re-litigating what Google says about them, so read Google info. The rankings are not without some controversy and there are competing ranking metrics of journals. Each different ranking method put emphasis on different criteria and weight different criteria differently.

I checked their database for the ranking given to the podiatry and related journals and compiled this list:

Reflexology research …. ‘low hanging fruit’

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.
