Clinical research into channel diagnostics and treatment yields remarkable results

From a scientific point of view, traditional Eastern diagnostic procedures have always been regarded as ‘intangible’. However, fifteen years of research at St. Petersburg University has yielded remarkable results. Dr. Valeri Mujikov, a surgeon and researcher, has established many correlations between traditional Eastern channel diagnostics and medical conditions. Dr. Mujikov’s work has led to the development of the Merid: a diagnostic and therapeutic instrument that bridges the gap between traditional Eastern medicine and Western demands for reliability and reproducible results.

Measurements performed by the Merid will provide the practitioner with detailed information on a patient’s vitality and health. Causes of symptoms and complaints – including the so-called functional complaints that give medical doctors hardly any clues – can be established within a few minutes. The Merid can also be used effectively for preventive purposes: measurement results clearly show if problems are imminent, enabling the practitioner to take appropriate action.
In addition, the Merid can be used to treat conditions and disturbances. The patient will feel the effect instantly, and results can be easily substantiated by performing another Merid measurement.


Traditional Eastern medicine comprises many different diagnostic methods and techniques.
One of these was developed in 1950 by Jakobe Akabane, and has since been known as the Akabane Test. The Akabane test provides an assessment of the channels that control and link all bodily functions and processes. Jakobe Akabane used a glowing sandalwood stick for this purpose. He held the hot tip close to the end-points of the channels, (which are located on the fingertips and toes), until the patient experienced a mild burning pain. The time that elapses indicates the energy level of the channel: if the level in the channel is high, then the patient will experience the sensation of heat very quickly; conversely, if the energy level of the channel is low, it will take longer before the patient will experience any pain.
Physiologically, a high level of energy in the channel indicates that stimulation of the organ system linked to that channel is not necessary, since the body’s feedback mechanism quickly triggers a response. However, a response that is felt considerably later, indicates that stimulation is necessary. The differences in response time are notable, and will vary over time with the increase or decrease of activity within the organ system. In that respect, the energy channel may be regarded as a control or regulating mechanism.
Akabane also recognised the importance of the difference between the left-hand and right-hand channels. A large difference in response times for left and right indicates that the regulating mechanism is unstable. This is called energetic pathology. When this is not addressed appropriately, it may result in physical pathology.

Objective and reproducible measurement

Dr. Mujikov built on Akabane’s work and devised a scientifically valid measurement procedure that is objective and reproducible. The first step was to replace the glowing sandalwood stick with a heat source that could be controlled precisely. To this end, a unique, patented diode that radiates modulated, infrared light was engineered. The diode itself will remain cool to the touch, so it can be safely placed on the fingertips and toes in order to measure the channels. In addition, Mujikov and Sanet BV, the Merid’s manufacturer, developed user-friendly software that analyses the measurement data and presents the results in the form of clear, yet comprehensive, diagrams and graphics.
If the results show that one or more channels are out of balance, the diode can also be used for therapeutic purposes. The infrared light is modulated in a different way, and specific points on the body are treated to restore the corresponding channels’ regulating mechanism. When a patient is treated using modulated, infrared light, the body’s natural feedback mechanism will trigger a response when the energy in the channel is restored to its required level. At that precise moment, the patient will feel a very sudden, sharp sensation of heat, which indicates to the practitioner that treatment on that point should cease.


Valeri Mujikov has tested and further developed this diagnostic and therapeutic method in clinical practice. By comparing thousands of patients’ test results with their medical records he has succeeded in establishing correlations between specific values and medical conditions like diabetes, CFS and high blood pressure.
In the case of diabetes, for instance, blood samples were compared to measurement results, which clearly showed that the amount of left-to-right asymmetry on specific channels is consistent with glucose levels. Dr. Mujikov’s article on diabetes can be found on Sanet BV’s website ( An outline of a research project initiated by Dr. Mujikov in 2001 is presented below.

Working with the Merid

In order to measure the channels, the infrared diode connected to the Merid is placed consecutively on all twenty-four end points, or BAPs (Biologically Active Points), which are located on the fingertips and toes. The number of light pulses each point can ‘take’ until the patient experiences a sudden heat sensation is directly related to the energetic activity of the channel. Physiologically, we can infer the status of several functions within the organ system associated with the channel from this number of pulses. In addition, the difference between the left-hand and right-hand side of the channel tells us how the organ system performs as a whole.
After each measurement procedure, the practitioner can view the data directly on the Merid’s built-in display. Once the data have been transferred to a PC, the Merid software will process the data to facilitate computer-aided analysis. The software can also show the practitioner which points should be treated in case of disturbances or imminent pathology.
Recorded measurement data, gathered from several measurement procedures, can be used to monitor a patient’s progress, or to perform statistical surveys.
In addition, Sanet Medical BV is currently engineering an expert, online system that practitioners can access to further analyse their measurement data.

The 2001 research project

The primary goal of the clinical tests was to compare the results of temperature sensitivity measurements on the traditional acupuncture channels (AC) with the help of the Merid device and compare them with the results of standard diagnostic tools and methods for assessing physiological parameters. In addition, the effects of influencing acupuncture points with modulated infrared light were examined with respect to possible medical effects.
Research was carried out on two groups of patients within an age range of 24 to 50 years. The first group consisted of 28 individuals (16 women and 12 men), all of whom had been diagnosed with arterial hypertension.
On this group, 45 tests were executed. In the course of these tests, we measured both the basic hemodynamic parameters – i.e. the number of heart beats (HR) and the systolic arterial pressure (APs) – and temperature sensitivity on the BAPs (the Level Pain Threshold Sensitivity, or LPTS, value is the time which elapses until a sharp increase in pain is experienced).
The second group consisted of 15 patients with diabetes type 1 and 2 (9 women and 6 men). We compared temperature sensitivity (the LPTS value) on the BAPs with several biochemical blood parameters. Blood sugar levels were measured with a Glucometer (Elite-2000), while at the same time the LPTS value was measured with the Merid device. In total, 34 tests where done.

Measurement of temperature sensitivity (the LPTS value) was carried out in accordance with the procedure mentioned above.
Initially, temperature sensitivity was measured on random spots on the back of the hands. Specific acupuncture points on the channels Lu, LI, Hc, TH, Ht, SI, Sp, Liv, St, GB, Ki, Bl, were measured as well (in the order mentioned above). Measurement results were stored in the device’s memory, and subsequently transferred to the database of the computer program. Measurement results of the arterial pressure and blood sugar levels were entered into the database as well, in order to perform a standard step-by-step regression analysis.

Clinical effects were investigated by monitoring the LPTS values again after the patients suffering from hypertonic illness had been treated. Treatment consisted of applying modulated IR light on acupuncture channels that were selected on the basis of sinister/dexter LTPS value asymmetry exceeding 30%. The results of the second measurement procedure were compared to the results of the initial test. The level of change in LTPS values was calculated as a percentage change in comparison with the first test.

Test results

Heart rate (HR)
On evaluating the test results obtained from first group of patients, a correlation with a high reliability factor (t > 2,0) was found between the LPTS value and the HR parameter (Tab. 1) by using the regression model of the Merid software. Higher numbers of the HR value correlate with higher numbers of the LPTS value of the Hc-d (Pericardium right-side) and Ki-s (kidney left-side) acupuncture channels. On the other hand, a lower value of HR correlates with higher LPTS values of the Bl-s (bladder left-side) and LI-s (large intestine left-side) channels. The LPTS value of SI-s (small intestine left-side) could be correlated with a reduction of the HR value with a lower influence factor (t < 2,0).
This offers several opportunities to use the Merid for correcting the bradi- and tachy- syndrome.

Using a simple standard step-by-step regression technique we could describe the HR with the following formula

HR = -0.72 * (LI-s) + 1.51 * (Hc-d) + 1.11 * (Ki-s) -1.40 * (Bl-s) + 65.35

Arterial pressure (AP)
In addition, a correlation between the LPTS value and the APs value was established (Tab. 2). The arterial pressure correlates (t > 2,0) with the LPTS value of the Ki-d (Kidney right-side) channel. A less pronounced correlation was found (t =1.94) between the APs level and the TH-d (Triple heather right-side) channel.
On the other hand, a decrease of APs correlates with an increase of the LPTS value of the GB-d (gall bladder right-side), St-d (Stomach right-side), and Ki-s (Kidney left-side) channels. However, a lower t-factor (t < 2.0) was involved.
The specified correlated channels can be used for correcting the arterial pressure, as was checked in clinical practice. To assess the effects of modulated infrared radiation as a means of treatment, we analysed 26 treatment procedures with the Merid on AP channels, which, on the basis of models established before, were expected to influence the level of arterial pressure.
40 minutes after treatment, we found that the relevant LPTS values had decreased by an average of 32%, which corresponds to values to be expected when the arterial pressure level is normal. At that moment, the sinister/dexter LTPS value asymmetry had decreased by 86%. One hour after treatment, a reduction of the systolic arterial pressure level with an average of 24% was found.

Using a simple standard step-by-step regression technique we could describe the AP with the following formula

Art Pressure H = 3.38 * (TH-d) - 1.18 * (St-d) - 2.07 * (GB-d) + 3.32 * (Ki-d) - 1.53 * (Ki-s) + 132.25

Blood sugar
With the test results obtained from the second group of patients, we tried to establish a correlation between the LPTS parameters and the blood sugar level. From table 3 you can conclude that the increase of blood-sugar levels corresponded with the LPTS thresholds of the Liv-d (liver right-side) and Bl-s (bladder left-side) channels with a t factor > 2,0.
On the other hand, a decrease of blood sugar levels is consistent with an increase of the LPTS levels of Liv-s (liver left-side) (t =2,94), and, to a lesser degree, with SI-s (small intestine left-side) (t=1,22). This suggests that the specific AP channels and their LPTS values, as measured in this model, are closely related to the regulation functions of several systems of the human body. In addition, by influencing these points, it is possible to change certain physiological parameters in different organisms according to the model used.
In the course of our research, the method of measuring the LPTS value with the modified Akabane test, as was done with the Merid, combined with mathematical analysis, enabled us to arrive at a reliable medical diagnosis. Treating the relevant points proved to have a real medical influence.

Using a simple standard step-by-step regression technique we could describe the Sugar level with the following formula

Sugar = -0.15 * (SI-s) + 0.83 * (Liv-d) - 0.98 * (Liv-s) + 0.20 * (Bl-s) + 4.56

Bridging the gap

K.P. Gamajunov, Senior Lecturer at St. Petersburg Medical Academy, and N. Bogdanov, professor of Medical Science, stated in the conclusion of a paper on the research project outlined above:
“Devices (…) correspond to the "Specifications" of the Committee on New Medical Techniques of the Ministry of Health of the Russian Federation. The device can be used for diagnostic purposes in order to determine the functional condition of an organism based on physiological parameters of an acupuncture point. Their production and introduction in clinical practice are recommended.”

The effectiveness of working with the Merid has been amply demonstrated in clinical practice. The entire measurement procedure is non-invasive and takes only a few minutes.
Working with modulated infrared light as a therapeutic means bears a resemblance to several traditional Eastern techniques. Acupuncture is the best-known example, although, from a scientific point of view, it is yet unclear how exactly acupuncture needles affect the body. It is generally agreed that inserting a needle provokes a stress-reaction, but whether this reaction is stronger if the classic acupuncture points are used, is still debated. In addition, the influence of factors like the type of needle, the time elapsed and the penetration depth, are unknown.
The influence of modulated infrared light, however, can be assessed in a scientifically valid way. The amount of energy, which is electronically controlled, is exactly known, and will not be influenced by disturbing factors such as density of the skin. Moreover, the body’s natural feedback mechanism will trigger a pain reaction when a specific point has been treated sufficiently. This pain reaction is so sudden that there can be no doubt whatsoever with regard to the ‘time’ factor.
To conclude this brief outline of differences between acupuncture and the Merid, we would like to point out that the patient reports of a subjective feeling of wellbeing can be substantiated by performing a second measurement procedure. This will clearly show whether the patient is just feeling better, or whether the situation has objectively improved.
