The Directional Non-Force Technique

Dr. John with patient By Christopher John, D.C.

The Directional Non-Force Technique (D.N.F.T.) is a very specific manner of diagnosis and adjusting in chiropractic originally developed by Dr. Richard VanRumpt. VanRumpt began his earliest investigations in 1923 as a student at the National College of Chiropractic, and he single-handedly taught this method at seminars throughout the country for almost 50 years.

Initially inspired to develop the D.N.F.T. while still a student, VanRumpt discovered that some deep lumbar palpation rendered on a patient provided relief to many symptoms. The notion that a less forceful approach could correct subluxations intrigued him, as did the phenomenon of changes in leg length.

Before entering chiropractic college,he had been a professional boxer.

It was then that he developed an interest in leg measurement from his boxing coach. The coach apparently utilized some rudimentary form of leg check as a guide to adjustment that he then rendered to his boxers. It took VanRumpt a number of years of personal research to develop an approach, utilizing a leg check and light-force adjusting which he felt enough confidence in to teach to others.

The advantages of this technique are many. Less force, the lack of torque and "audible articular sound" are aspects very much appreciated by many patients. More important is the accuracy and specificity of analysis of subluxations and the associated correction. The ability to analyze subluxations without X-rays, and having few contraindications for adjusting are other advantages. And finally, the power of the adjustment, the long-lasting nature of the correction and the speedy recovery of most patients are important advantages.

Non-Force Technique

The term "non-force" is slightly inaccurate with respect to how the adjustment is rendered. It is, rather, light-force or lowforce in nature. The efficacy of a low-force, lowamplitude, high-speed impulse is a result of the diagnostic and adjusting accuracy. Simply stated, when you are at the right place at the time thrusting in the right direction, the body accepts the correction totally and permanently.

As used here, the term "permanently" simply means that we do not have to repeat this adjustment again and again in order for it to hold the correction. If the subluxation is corrected properly, including all elements, then one adjustment will do the job!

There is a legitimate rationale, however, for preventative maintenance. This is because new subluxations can be incurred from a number of sources. My idea of optimal patient maintenance is one visit every one to four months.

I have heard many different reasons and excuses for why a patient should have to come in to the office so many more times than this (for maintenance), but I do not agree with them. Students and doctors should seriously consider their own rationale for continued adjustments and how many visits are typically required to correct a condition. For me, it is a combination of several things: finding no or few subluxations with the D.N.F.T. analysis, symptom removal or stationary status, negative ortho/neuro tests and range-of-motion testing.

For a simple localized problem such.as neck pain or mid-back pain, the problem can often be eliminated with two to five adjustments. For more serious problems, or for the effects of multiple injuries, five to nine visits would be my average.

While this is much less than we hear about in school and through practice management seminars, when one considers chiropractic ideals from a patient perspective, it can be seen that D.N.F.T. merits serious consideration by our schools and profession. This has not been done to date for a number of hard-to-understand reasons.

A Unique Approach

While other techniques may appear to resemble or contain elements of it, D.N.F.T. chiropractic is a 100 percent VanRumpt discovery. Currently there are similar techniques which are included in elective curricula in our schools, some of which are now more well known than the original Directional Non-Force Technique.

I would not berate these techniques for being included in elective curricula, but I would appreciate a level playing field. There has been more discrimination against D.N.F.T. chiropractic than you can imagine. I truly believe that if people understood exactly what the Directional Non-Force Technique is, there would not be such a furor over it.

Subluxation in D.N.F.T. philosophy is any misalignment of osseous or soft tissue that is actively producing nerve interference. The key phrase is "producing nerve interference." If a misalignment is visualized on x-ray or by some other means, yet is not actively producing nerve interference, it cannot be considered a subluxation, according to VanRumpt and me.

Both a challenge and a D.N.F.T. leg check are used to analyze subluxations. The challenge may be "hard" and consist of a light push by a finger, or it can be a polarity check by aiming the appropriate finger at a structure in a specific direction.

If the challenge is followed by a leg check within three seconds, and if there is a pull-up of the "reactive leg", then a subluxation and at least one component of its direction have been found. The pull-up of the reactive leg, properly done, is dramatic and is generally 1/2-inch to one full inch.

The reactive leg is a phenomenon which every human experiences. The body has the capacity to react to certain things in such a way that the musculature on one side of the body will contract. This contraction, if viewed on a patient in the supine or prone position, will appear as a temporary shortening of one side. It is most dramatic when viewed at the walking surface of the heel. This is not to be confused with a static or functional short leg.

This is also entirely different from the Derefield, Activator, Nucca or any other leg measuring system in chiropractic. According to VanRumpt, the Derefield leg check was being utilized by osteopaths prior to chiropractors. Incidentally, a literature survey on the Derefield was performed as part of a scientific study by Dr. Joanne Nyiendo of Western States Chiropractic College. From what I can recall of her lecture, there is very little understanding of the true nature of the Derefield leg check and what it means.

Correction of the Subluxation

Subluxations are corrected through a thumb thrust, which is best described as low-force, high-velocity, low-amplitude impulse. In the case of certain discs in certain directions, we also employ a specially modified 3/8-inch wood dowel with which we can perform a light thrust between the transverse process toward the center of the intervertebral disc. The disc correction is one of the main features of D.N.F.T. adjusting.

It is not necessary to "mobilize joints" to correct subluxations. Fixations are set up by the body itself to protect against further damaging effects of nerve interference. If the underlying subluxation is corrected, fixations are automatically released by the body. This fact is little known to chiropractic students throughout the country.

We invite any who are interested in conducting scientific research, and who would like to investigate this, to contact the president of our newly formed scientific research organization. Dr. Laura Henson, president of the newly formed D.N.F.T scientific research organization, would be glad to help develop a protocol for such a study.

Analysis of the Subluxation

X-rays have a number of legitimate uses in chiropractic, but analyzing subluxations is not one of them. You only analyze distortion and manifestations of subluxations, and not necessarily subluxations (which produce nerve interference). We utilize the body itself to be the indicator of the location and direction of the subluxation.

If nothing else, I would hope that what would be remembered is that Directional Non-Force Technique chiropractic is very basic, fundamental, pure chiropractic.

VanRumpt would quote D.D. Palmer when he said, "Find the subluxation, fix it and let the body heal. "

As I mentioned earlier, we now have a nonprofit educational organization, completely independent from D.N.F.T. seminars, that is dedicated to scientific research. We already have protocol for an initial scientific study and are poised to begin. Anyone can find out about this by dialing our hotline, selecting the scientific research voicebox, and leaving a message for Dr. Henson.

D.N.F.T. chiropractic has been taught as an elective for several years now at the Pennsylvania College of Straight Chiropractic and Southern California Chiropractic College. Relicensing seminars have also been sponsored by these two colleges.

Unfortunately, for the most part, teachers and administrators themselves do not know what D.N.F.T. is and either misrepresent it or do not teach it in history and philosophy classes at all. It is also not offered as an elective except in the schools I have already mentioned. As VanRumpt used to write, it is the most misunderstood technique in chiropractic.

I think the future of Directional Non-Force Technique is hopeful, based upon the formation of our scientific research organization. The technique has always stood on the merits of its results and is loved by patients and doctors all over the world. But now the call is out for demonstrable results. We welcome the challenge.
