Recently discovered the traditional Chinese medicine called Gua Sha, and I'm just in love with how hilariously absurd it ispic.twitter.com/3gP638kHjR
The basic idea is that you massage people with a smooth stone or similar instrument, causing a bit of bruising and reducing "stagnant energy" Needless to say, there is no such thing as "stagnant energy"pic.twitter.com/1jOJu9yViJ
What exactly is stagnant in this procedure is somewhat under dispute, but what is indisputable is that it makes no physiological sense whatsoeverpic.twitter.com/nj3PPs3Zgx
But, we don't base decisions on whether a therapy sounds ridiculous, we base them on research So here we go
There are not many trials of Gua Sha A 2010 systematic review found that the study quality generally was too low to make a judgement either waypic.twitter.com/RVPFydZqGl
After a look on Google Scholar and Pubmed, it appears that every single study cited in this review was published exclusively in Chinese and I can't find any of them in English Not...ideal
The studies I can find in English are...well. Not ideal either
This one is great: no statistical difference whatsoever between groups? No worries. We'll just imply that the non-significant differences are important anyway!pic.twitter.com/IrcQRLYENz
This blog from @EdzardErnst paints the picture about what is likely going on with Gua Sha very well https://edzardernst.com/2013/01/gua-sha-torture-or-treatment/ …
As far as I can tell, it's a clinical methodology that is limited to having someone bruise you intentionally, and has no good evidence for any benefits whatsoever Stay away!
Good grief! I bruise unintentionally quite sufficiently all by myself. Assistance I do not need.
