In 1951 Dr. Yoshio Nakatani presented his research and theory of RYODORAKU Acupuncture. Dr. Nakatani had found that there were a series of low electrical resistance points (or high electrical conductivity) running longitudinally up and down the body. When linked together these points closely matched the acupuncture meridians. Dr. Nakatani called these lines (or meridians) "Ryodoraku" (ryo = good, do` is (electro) conductive, raku = line). The points along the Ryodoraku he named Ryodoten
Dr. Nakatani was the first person to measure the electrical activity of acupuncture points and the first to formulate diagnostic and treatment criteria from these measurements. Nakatani was the first recorded acupuncturist to use electrical stimulation of acupuncture points. Point location and electrical stimulation has become the norm for most acupuncturists world wide but the Ryodoraku detection, analysis and point selection for electrical stimulation is much less popular. This is unfortunate as Nakatani's concepts provide an accurate pulse-organ diagnosis, accurate location of required treatment points and a very time efficient treatment regimen (generally only 7 seconds stimulation of each point is required. A classic acupuncture treatment lasting an average of 30 minutes would only take 2 - 3 minutes using Ryodoraku!)
The indications for Ryodoraku are identical to those for acupuncture, but the results are often faster. In particular acute pain and acute traumatic swelling e.g. sports injury will often respond during the initial treatment.
THEORY
A Ryodoraku unit called a "Neurometer" uses a constant voltage of 12V (occasionally 21V will be used in ear acupuncture) and a variable current (this current is set to 200uA for treatment) . To provide consistency and avoid artefacts because of dryness/wetness of skin a moist electrode is used to locate the points of lowered electrical resistance i.e. Ryodoten or Electro permeable Points (EPP).
The moist electrode consists of a small cup containing a plug of cotton wool soaked in saline (sometimes alcohol is used). This is run lightly over the skin until a high reading is seen on the meter i.e. this area of low resistance, high conductivity allows current to flow. An increase of 20-50 uA is expected. . As in other forms of electro acupuncture practice is required to achieve consistent results. Too much pressure or repeated checking of a point can change the electrical properties of the skin in that area and lead to error. Computerised measuring Ryodoraku units are available in Japan. These give a steady 3g electrode pressure to the skin.
This EPP can then be located exactly by using the fine probe in the two or three headed point locater on the Ryodoraku unit see diag.
Nakatani discovered that the number of electro permeable points not only varied with any disease process but also with the voltage of the detector probe. Most of the traditional acupoints could be located if a 21 volt circuit was used. However if a 12 volt circuit was used, there were other electrically conductive points over the body, not associated with any specific acupuncture points. He called these Responsive Ryodo-pointsor Reactive Electropermeable points (REPPs). These points often correspond with trigger points or Ah Shi (tender to touch) points. Nakatani theorised that they occurred along tracts of the Autonomic Nervous system and were representative of internal disorder/dysfunction and/or disease.
Nakatani showed that needling these REPP, and stimulating them for 7-10 sec with a 200uA charge would render them electrically inert and produce symptom relief. Headaches, neck aches, back aches and acute pains would often be relieved - sometimes in minutes, sometimes over several days. This is a very effective form of local or regional acupuncture but Nakatani developed it further.
Using his knowledge of the Ryodoraku pathways Nakatani formalised Ryodoraku acupuncture. He used the same concepts of the twelve paired acupuncture meridians or organ systems (Heart, lungs, triple warmer,pericardium, large intestine, small intestine on the upper limbs and gall bladder, stomach, liver,kidney, bladder and spleen on the lower limb ) and the two single midline meridians (anteriorly, Conception Vessel and posteriorly, Governing Vessel). However he did not use the classical names. He assigned the letters "H" to each of the six Ryodoraku on the upper limbs numbering them from one to six. Similarly he assigned the letter "F" to each of the six Ryodoraku on the lower limbs, numbering them from one to six. Thus H3 represented the Heart meridian on the upper limb; F6 represented the stomach meridian on the lower limb.
To further confuse the issue (at least as far as traditional acupuncturists were concerned) Nakatani did not use either the Chinese name nor the more commonly accepted, international numbering of acupuncture points. [He numbered his Ryodo points starting at the end of each limb]. Acupuncture uses the Yin- Yang energy flow concepts to number its acupuncture points. Thus energy flows outwards towards the end of a limb along one meridian ad back to the trunk along another meridian i.e. the meridians are paired off. In the paired meridians Lung and Large Intestine energy starts on the trunk in the Lung meridian so L1 (the first Lung meridian acupuncture point)is on the anterior chest. The first point for the Large Intestine meridian (LI. 1) is on the index finger. In Nakatani's Ryodoraku system both H11 (the first Ryodo point on the large intestine Ryodoraku) and H51 (the first Ryodo point on the lung Ryodoraku) are on the finger tips.
Nakatani believed this was a much simpler way of representing and teaching acupuncture. No knowledge of the complex acupuncture nomenclature, philosophy and mnemonics was required. In fact a therapist theoretically did not even have to memorise the exact position of the acupuncture points. He/She could use the Ryodoraku Neurometer to locate the points.
In a further departure from traditional acupuncture Nakatani compared readings from Ryodoraku on the right side of the body with those of the same Ryodoraku on the left side of the body. If one side showed higher (or lower) reactivity than the other, he would use a specific needling procedure to bring the EPP readings to the same level. When the right and left paired Ryodoraku [eg. right and left H1 (Lung) Ryodoraku] had the same electrical reactivity, the body was balanced for that organ system.
Initially, Nakatani measured the electrical resistance of each and every EPP along a meridian, added them together and divided by the total number of EPP. This gave him an average energy value for that meridian. This was obviously very time consuming and, eventually, Nakatani discovered that there was a point on each meridian that was representative of the energy in that meridian. He named this point a Representative Measuring Point (RMP). Thus there are 24 RMP - six on each wrist and six on each foot.
These twenty four points were measured and charted on a special chart, the left side being compared with the right side for the paired meridians.
LOCATION OF REPRESENTATIVE MEASURING POINTS (RMP)
The representative points for H1, H2, H3 (Lung, Pericardium and Heart respectively) are found along the distal transverse skin crease on the anterior (or palmarl) surface of the wrist. Each point is a traditional acupuncture point eg. H3 is over L9 (Lung 9),
H2 = Pericardium7,
H3 = Heart 7,
H4 = Small Intestine 4,
H5 = Triple Warmer 4,
H6 = Large Intestine 5
See Chart ..............
For non acupuncturists Nakatani devised a simple measurement technique for locating the wrist points:
Place a thumb over the anterior(palmar) surface of the patient's wrist at the distal skin crease. Place the middle finger on the opposite (dorsal) side of the wrist. Hold thumb and middle finger firm and withdraw. Place thumb and middle finger over either anterior or dorsal surface of the wrist at the distal skin crease. There should be an equal distance from radial or ulnar borders of the wrist and the thumb/middle finger. The representative points H1, and H3 anteriorly and H4, H6 dorsally are under the thumb and middle fingers. H2 is centrally between H1, and H3. H5 is closer to H4 than H6, being in the line of the ring finger.
Four of the foot (F) representative points are traditional acupuncture points. The other two are between acupuncture points but are on the appropriate meridian. The F3 (Kidney) representative point is on the kidney meridian at the postero-inferior tip of the medial malleolus and the F6 (Stomach) representative point is on the stomach meridian half way between Stomach 41 (S41) and Stomach 44 (St44) . See photos.
Nakatani determined empirically, from testing thousands of patients, that the average/normal value for the Ryodoraku varied
1. from one person to another
2. from one Ryodoraku to another
3. throughout the day
4. with changes in environmental temperature
5. body temperature.
He devised a weighed scale on which the 24 representative readings could be charted then a 1.4 cm ruler could be placed horizontally to cover the maximum number of charted values and two parallel lines drawn. Values within the lines were considered normal for that individual. Values above the top line or below the bottom line indicated a need for acupuncture needling in one or more points along that Ryodoraku). Nakatani later simplified this ruler technique. He discarded the 1.4.cm ruler concept and instead drew one horizontal line just below the three highest readings and one just above the three lowest readings. He then needled and electrically stimulated points in each of the Ryodoraku outside of the parallel lines i.e. the three highest and three lowest .
Ryodoraku Patient Assessment Chart. This chart contains
(1) A chart originally devised by Nakatani for entering the values obtained by measuring each of the 24 representative points for the Ryodoraku.
(2) Diagrams indicating the position of each of the representative points.
(3) Space to enter diagnosis/room temperature/body temperature
(4) A table of commonly used points for sedation or tonification of each Ryodoraku. Experienced acupuncturists will note these points are the classical Luo -Connecting Points for transferring energy from one meridian to include another. This table was devised by Dr Gerald Gibb, a New Zealand rheumatologist, considered by many to be the father of New Zealand acupuncture. Dr Gibb worked with Nakatani in Japan for two years and is a mine of information not only on Ryodoraku but also on every aspect of acupuncture.
TECHNIQUE / PROCEDURE for RYODORAKU ASSESSMENT AND TREATMENT.
(1.)Soak cotton wool plug in saline and insert into cup on end of probe. Leave approx 1mm protruding.
(2.) Touch the hand electrode with the probe and adjust the meter to 200.
(3.) Have patient hold the hand electrode.
(4.) Run probe lightly over each of the 24 representative Ryodo points and enter the value for each one on the Ryodoraku chart.
(5.) On the chart draw a line just below the three highest readings and another line just above the three lowest readings.
(6.) For the three highest readings select one or more of the sedation points for each Ryodoraku from the table below the Ryodoraku chart. Similarly for the three lowest readings select one or more of the tonification points for the respective Ryodoraku.
(7.) Point by point insert an acupuncture needle into each of the selected points and touch the metal part of the probe to the needle allowing current to flow for seven seconds.
(8.) Where symptoms or signs are localised run the cotton wool soaked probe lightly over the skin within that area. Checking for any REPPs (Reactive Electropermeable Points) with the dial set for 12 volts. Needle any REPPs found and apply the metal head of the probe to the shaft of the needle for seven seconds.
TREATMENT CONSIDERATIONS
Originally Nakatani followed the traditional Chinese acupuncture concepts of sedating the high points and tonifying or stimulating the low points. Thus stimulation involved inserting a needle superficially, leaving it for 3 - 4 seconds then removing without any electrical stimulation. Sedation required strong manual stimulation followed by a 7 second burst of 200mA current. In many cases Nakatani found that this differentiation was not needed and that electrical stimulation for 7 seconds at 200m A helped both low and high points. The body somehow only took in the amount of energy it needed.
The second modification involved the use of substitution points instead of General Regulatory Points (GRP). Nakatani found that the GRP points on his original charts and on Gibb's modification were around fingertips and tips of toes - all very painful and consequently not very popular with patients. He reasoned, and later proved empirically, that other points could just as easily be representative entry points for a meridian. These points were located just distal to the elbow and the knee. As Kenyon ( Modern Techniques of Acupuncture) says
If Ryodoraku treatment is carried out using the chart points as indicated then only the most tolerant patients will return for further treatment. The use of so-called substitution points gets round this problem. There is one for each meridian. On the arms they are situated in a band around the top of the forearm at the level of Large Intestine 10. On the leg they are situated in a band around each calf at the level of Bladder 57 (i.e., at the level of maximum girth of the calf,) The object of sedating or stimulating any meridian by use of the same point, i.e. the substitution points, is achieved entirely by the needling technique as described above. For stimulation, superficial needling leaving the needle in only for 3 seconds without electrical stimulation is used. For sedation, deep needling with manual manipulation and the application of a 200mA current for 10 seconds is used. The use of these points makes Ryodoraku much more acceptable from the patient's point of view. Lastly, local treatment is used on the REPPs detected around the site of the patient's problem.
.......it is remarkable that stimulation at 200mA which often cannot be felt and is passed for such a short time can be so effective. This is another finding in favour of an energy flow/meridian mode of action as opposed to the more popular neurological and neuro-endocrinological explanations which currently swamp academic medical interest in acupuncture."
