The authors offer the following conclusions:
After 45 years of study, scientific evidence of the value of TT as a complementary intervention in the management of any condition still remains immature and inconclusive:
- Given the mixed result, lack of replication, overall research quality, and significant issues of bias identified, there currently exists no good-quality evidence that supports the implementation of TT as an evidence‐based clinical intervention in any context.
- Research over the past decade exhibits the same issues as earlier work, with highly diverse poor quality unreplicated studies mainly published in alternative health media.
- As the nature of human biofield energy remains undemonstrated, and that no quality scientific work has established any clinically significant effect, more plausible explanations of the reported benefits are from wishful thinking and use of an elaborate theatrical placebo.
These are clear and much-needed words addressed at nurses (the paper was published in a nursing journal). Nurses have been oddly fond of TT. Therefore, it seems important to send evidence-based information in their direction. In my recent book, I arrived at similar conclusions about TT:
- The assumptions that form the basis for TT are not biologically plausible.
- Several trials and reviews of TT have emerged. However, many of them are by ardent proponents of TT, seriously flawed, and thus less than reliable. e.g.,
- One rigorous pre-clinical study, co-designed by a 9-year-old girl, found that experienced TT practitioners were unable to detect the investigator’s “energy field.” Their failure to substantiate TT’s most fundamental claim is unrefuted evidence that the claims of TT are groundless and that further professional use is unjustified. 
- There are no reasons to assume that TT causes direct harm. One could, however, argue that, like all forms of paranormal healing, it undermines rational thinking.
