Over the decades, many clinical studies have been performed to investigate TT's efficacy, as well as various
meta-analyses and at least one
systematic review, yielding varying results and conclusions. O'Mathúna
et al., in discussing these studies, note several problems, such as failure to exclude methodologically flawed studies and a susceptibility to the
publication bias of complementary medicine journals, which carry a "preponderance of studies with positive results"; they argue that
Emily Rosa, at nine years of age, conceived and executed a study on therapeutic touch. With the help of
Stephen Barrett from
Quackwatch and the assistance of her mother, Linda Rosa and her step-father Larry Sarner, Emily became the youngest researcher to have a paper accepted by the
Journal of the American Medical Association (
JAMA), which
debunked the claim of therapeutic touch practitioners can reliably sense a "Human Energy Field." Twenty-one practitioners of therapeutic touch participated in her study. The practitioners sat on one side of a cardboard screen, while Emily sat on the other. The practitioners then placed their hands through holes in the screen. Emily flipped a coin to determine which of the practitioner's hands she would place hers over (approximately 4-5 inches above the subject's hand). The practitioners then were to say where her hand was by sensing her
biofield. Although all of the participants had asserted that they would be able to do this, the actual results did not support therapeutic touch's fundamental claim. The practitioners had succeeded in locating Emily's hand 44% of the time, a rate within the range of chance.
JAMA editor George D. Lundberg, M.D, recommended that third-party payers and the public should question paying for this procedure "until or unless additional honest experimentation demonstrates an actual effect." but in 2016, the authors
retracted it after the validity of the reviewed studies was questioned. == Skeptical view of therapeutic touch ==
