In 1996, Rosa saw a video of Therapeutic Touch (TT) practitioners claiming they could feel a “Human Energy Field” (HEF) emanating from a human body and could use their hands to manipulate the HEF in order to diagnose and treat disease. She heard Dolores Krieger, the co-inventor of Therapeutic Touch, claim that everyone had the ability to feel the HEF, and Rosa heard other nurses say the HEF felt to them “warm as Jell-O” and “tactile as taffy.” Rosa was impressed by how certain these nurses were about their abilities. She said, “I wanted to see if they really could feel something.”[1]
Using a standard science fair display board, Rosa devised a single-blind protocol, later described by other scientists as “simple and elegant,” for a study she conducted at age nine for her 4th grade science fair. There were two series of tests. In 1996, 15 practitioners were tested at their home or office on different days over a period of several months. In 1997, 13 practitioners, including 7 from the first series, were tested on a single day. The second series was observed and videotaped by the producers of Scientific American Frontiers. Stephen Barrett, MD, of Quackwatch helped Rosa, her mother (Linda Rosa, RN), and stepfather (Larry Sarner) write up the experiment for JAMA. The study was published April 1, 1998. George Lundberg, editor of JAMA, aware of the uniqueness of the situation, said: “Age doesn’t matter. It’s good science that matters, and this is good science”.[2]
The study tested the ability of 21 TT practitioners to detect the HEF or “aura” when they were not looking. Rosa asked each of the practitioners to sit at a table and extend their hands through a screen. On the other side of the screen, Rosa randomly selected which of the TT practitioner’s hands she would hold her hand over. The TT practitioners were then asked which of their hands detected Rosa’s HEF. Subjects were each given ten tries, but they correctly located Rosa’s hand an average of only 4.4 times. Some subjects were asked before testing to examine Rosa’s hands and select which of her hands they thought produced the strongest HEF. Rosa then used that hand during the experiment, but those subjects performed no better. The results showed that TT practitioners could not detect the hand more often than chance, and Rosa et al therefore concluded that there was no empirical basis to the HEF and by extension therapeutic touch.
