Introduction:The Bi-Digital O-Ring Test Method was originally discovered by Yoshiaki Omura, M.D., in 1977 as a non-invasive diagnostic tool. Many experiments have shown that the basic mechanism of the Bi-Digital O-Ring Test. Dr. Yoshiaki Omura thoroughly investigated the effects of acupuncture on microcirculation, cerebral circulation, and the neuromuscular system. Dr.Omura examined many patients with confirmed diagnoses to determine accurate organ representation points.


Results: Dr.Ozerkan measured the grip strength of ten right-handed basketball players by both a dynamometer and by using the Bi-Digital O-Ring Test, in order to show the effects of watching two different psychological states such as smiling and crying on their grip strength, by subjecting them to the drawings of a smiling and a crying face. He found that the players’ grip strength, which was measured by using both a dynamometer and the Bi-Digital O-Ring Test, was higher after looking at the smiling face than it was after looking at the crying face drawing. This increase in grip strength as measured by a manual dynamometer was statistically significant. Similarly, the Bi-Digital O-Ring Test findings were also statistically significant


Dr.Ozerkan, in other research has measured skin resistance of acupoint Yintang after the players had looked at the drawing of a “smiling face” by using an ohmmeter (UNI-K multitester) and the Bi-Digital O-Ring Test successively. While the “smiling face” drawing was shown to the players, the values obtained by using the ohmmeter increased and the values obtained by using BDORT decreased. Results of measurement of both method were similar and meaningful.This results also support  the validity of the Bi-Digital O-Ring Test data.


Ozerkan et all. measured electrical properties of acupuncture point,Yintang by using Bi-Digital O-Ring Test and LCR-meter on the twenty right-handed young  soccer  players, after the players looked at the drawing of a “crying face” for 10 seconds from a distance of 40 cm at the eye level. Immediately afterwards, they were shown the drawing of a “smiling face”. Electrical resistance of acupuncture point,Yintang for each player was measured while the players looked at the drawing of a “crying face” from a distance of 40 cm at eye level in various frequencies (20Hz,200Hz, 2KHz, 20KHz) for 10 seconds.Then proceeded to measure the same variables on the acupuncture point,Yintang using the “indirect Bi-Digital O-Ring Test. while looking at “crying face”drawings, the values obtained by using LCR-meter increase and the values of BDORT’s measurement  decrease or vice versa. This study was performed in order to compare the validity of the findings obtained by using both BDORT and LCR-meter. This results also support the validity of the Bi-Digital O-Ring Test data.


Conclusion: Research carried out by comparison both routin measurement method and BDORT shows the same result. Results also support the validity of the Bi-Digital O-Ring Test data. Further research carried out in this area will certainly depict a more reliable statistical result.
