* Warner Brothers, Burbank, CA, 1988. was found to be calibrated in synchronization with another similar monitor (although the key factor was the difference between the pre/post blood pressure measurements). One trained student conducted all blood pressure and heart rate measurements. The study participant then either put on headphones or began receiving a reiki treatment from the real practitioner or a placebo treatment from the sham practitioner. During the 20-minute treatments, there was no talking allowed. This was done in order to standardize the experience among different groups. After the treatments were finished, the participants filled out the same posttest questionnaire, rating physical and mental relaxation levels. The participants’ blood pressures and heart rates were again measured immediately at the end of the treatment.
