The 7th Domestic Preliminary Survey on the Efficacy and Safety of Okada Purifying Therapy

Kiyoshi Suzuki, MD, PhD
President, MOA Health Science Foundation

Okada Purifying Therapy is a type of energy therapy and is an important pillar of the Okada Health and Wellness Program advocated by MOA. Research on energy therapy is quite difficult, but the MOA Health Science Foundation has continued research on Purifying Therapy for many years and published the results in medical journals in Japan and overseas. Recently, the research content of Okada Purifying Therapy has been attracting attention overseas.


I gave an overview in “Effects and Safety of Okada Purifying Therapy” in Column 2, but from this time on, I will introduce the representative research results that we have conducted so far in a series. First of all, I would like to talk about the “National Survey of Bioenergy Therapy-Effectiveness / Safety and Related Factors (Journal of the Japanese Society of Integrative Medicine 2009; 2: 37-43),” which triggered the widespread recognition of Okada Purifying Therapy.

1. Purpose of research

There are two main ways to study energy therapy. One is a method of strictly measuring changes due to treatment using the latest equipment and technology. The other is a method of analyzing changes after treatment for many people.


In this study, using the latter method, 1) how much the symptoms improve with Purifying Therapy, 2) are there conditions that make it easier for the symptoms to improve / enhance, and 3) do the improvement rates and conditions differ depending on the country or ethnic group? Based on such plan, we started to investigate. In November 2006, we conducted a preliminary survey in Japan to prepare for a full-scale international survey. Although it was still a preliminary stage, surprisingly, about 14,000 people participated in just two weeks. There is no other research on energy therapy with so many people participating in the world.

2. Participant background and survey method

More than 75% of those who cooperated in the survey were women, more than 55% were over 60 years old, and more than 80% were certified Purifying Therapy therapists (MOA members). There is a great deal of bias in the demographics of the participants, so a survey of all Japanese citizens could have yielded different results.


Participants received the treatment for 30 minutes or more. Before and after the treatment, the degree of symptoms of 1 body pain, 2 irritability / anxiety / depression (psychiatric symptoms), 3 palpitation / cold limbs / dizziness (autonomous neurological symptoms) had to be evaluated by participants in five stages (0: none, 1: a little, 2: a little, 3: pretty, 4: very). Seventy-five percent had physical pain before the treatment, 50% said they had psychiatric symptoms, and 40% had autonomic symptoms.

3. Result of investigation

Please see the figure. More than 70% of people answered that their physical pain, psychiatric symptoms, and autonomic nervous system symptoms improved after the treatment. 21.5% to 24.9% of the respondents answered that their symptoms did not change, which means that a majority of the people felt the change in their symptoms.


Looking at the conditions under which the improvement rate was the highest, it was the case where the woman received the treatment for 60 minutes or more. It is difficult to judge whether women are really easier to improve or whether it is due to their kindness toward the practitioner who administered the treatment.

1.5% to 4.5% of the respondents answered that their symptoms increased after the treatment. However, the increase in symptoms was temporary. Most people recovered within a few hours by watching the situation or adding treatment. As an interesting result, many MOA members over the age of 60 had increased body pain after the procedure. According to the theory of Purifying Therapy, the treatment may dissolve toxins (spiritual clouds) in the body and temporarily increase the symptoms. Those MOA members, who are familiar with the theory, may have taken the increase of symptoms as validation of the dissolving toxins. Thus, they may accept the increase in their symptoms as better than no changes in symptoms.


Thus, it is necessary to think carefully about how to interpret the obtained results. That is the real thrill of research and the difficulty.


Next time, I will introduce the results of an international survey of Purifying Therapy conducted from 2008 to 2009. I will share what is the same or different from this preliminary survey in Japan and the international survey. Please look forward to it.
