Bottom Line: In study 1, palm therapy was superior to sham therapy for both outcome measures.Future studies should attempt to separate possible mechanistic effects of Palmtherapy(R) from therapist-related variables.Palmtherapy(R) may offer anxiolytic benefit without the harm attributable to drugs.

ABSTRACT
Alternative medicine is widely used, but lacks consensus regarding its amenability to scientific investigation. Anxiety increases morbidity and mortality in ischemic heart disease. We performed two studies of Palmtherapy(R), an alternative treatment, for anxiety before cardiac catheterization. In the first study, patients were randomized to receive pressure at particular points on the palm, or at incorrect locations, for about 50 min, while the therapist conversed with them. In the second study, the conversation was conducted by a second, 'blind' investigator. In both studies, patients and nurses, all blind to treatment assignment, completed visual analog scale and National Institute of Mental Health measures of anxiety, respectively. Twenty-three subjects completed study 1, and 17 completed study 2. In study 1, palm therapy was superior to sham therapy for both outcome measures. In study 2, palm therapy was superior for self-reported anxiety, but not for nurses' assessments of anxiety. Future studies should attempt to separate possible mechanistic effects of Palmtherapy(R) from therapist-related variables. Whether alternative medicine deserves to be studied at all remains controversial. Palmtherapy(R) may offer anxiolytic benefit without the harm attributable to drugs.

Mentions: Potential subjects were told that palm therapy is an alternative treatment method that claims effectiveness against anxiety. The study had been approved by the hospital Helsinki Ethics Committee. The response rate was 100%. Subjects signed informed consent, and then were assigned, on the basis of pre-ordained random numbers, to one of the two treatment groups. One group received steady pressure just below the threshold of discomfort at the point designated by the originator of palm therapy (Fig. 1A) for 45 min. During this time, in study 1 the palm therapist conducted ‘small talk’ to distract the subject's attention, according to the treatment manual (10). Subjects assigned to the other group received the identical treatment, except that the pressure was exerted in the wrong (sham) location (Fig. 1B). After results from the first twenty-three patients had been analyzed, and the treatment appeared to have large effects, we conducted study 2, in which we included a second therapist, blind to treatment condition, to conduct the conversation, and the therapist exerting the pressure remained silent during the procedure.Figure 1.
