Reiki has been on my mind repeatedly (see for instance here, here, here and here). It is one of those treatments that are too crazy for words and too implausible to mention. Yet a new paper firmly claims that it is more than a placebo.
This review evaluated clinical studies of Reiki to determine whether there is evidence for Reiki providing more than just a placebo effect. The available English-language literature of Reiki was reviewed, specifically for
- peer-reviewed clinical studies,
- studies with more than 20 participants in the Reiki treatment arm,
- studies controlling for a placebo effect.
Of the 13 suitable studies,
- 8 demonstrated Reiki being more effective than placebo,
- 4 found no difference but had questionable statistical resolving power,
- one provided clear evidence for not providing benefit.
The author concluded that these studies provide reasonably strong support for Reiki being more effective than placebo. From the information currently available, Reiki is a safe and gentle “complementary” therapy that activates the parasympathetic nervous system to heal body and mind. It has potential for broader use in management of chronic health conditions, and possibly in postoperative recovery. Research is needed to optimize the delivery of Reiki.
These are truly fantastic findings! Reiki is more than a placebo – would have thought so? Who would have predicted that something as implausible as Reiki would one day be shown to work?
Now let’s start re-writing the textbooks of physics and therapeutics and research how we can optimize the delivery of Reiki.
Hold on – not so quick! Here are a few reasons why we might be sceptical about the validity of this review:
- It was published in one of the worst journals of alternative medicine.
- The author claimed to include just clinical trials but ended up including non-clinical studies and animal studies.
- Four trials were not double-blind.
- There was no critical assessment of the studies methodological quality.
- The many flaws of the primary studies were not mentioned in this review.
- Papers not published in English were omitted.
- The author who declared no conflict of interest has this affiliation: “Australasian Usui Reiki Association, Oakleigh, Victoria, Australia”.
I think we can postpone the re-writing of textbooks for a little while yet.
