Richard Van Rumpt

Richard Van Rumpt came to chiropractic by an unusual path: as a young man he was a professional bantamweight boxer in New York, fighting under ring names such as "Kid Ritchie." An injury led him to a chiropractor — and on to the National College of Chiropractic, from which he graduated in 1922. Because of his build he was at first known as one of the hardest "adjusters" in his school, until a chance observation changed his course: a patient he had only palpated intensively, but not formally adjusted, reported marked improvement the next day. Van Rumpt concluded that the forceful thrust was not necessary — that a very precise, light pressure might suffice.

From 1923 onward he developed this insight, over decades, into Directional Non-Force Technique (DNFT). Its core is a two-step procedure: a gentle, directional "challenge" against a structure, followed by a highly specific leg-reflex test — the "reactive leg reflex" he devised — by which the body itself indicates whether, and in which direction, a correction is needed. Correction is then made through a fine, directional thumb impulse, without the cracking typical of many techniques. Van Rumpt was convinced this directly consulted the body's "Innate Intelligence" — which earned him the nickname "Van – The Innate Man" and anchored his method firmly in the vitalistic tradition of D.D. Palmer.

In the 1920s and 1930s Van Rumpt was at first a student of Major DeJarnette and led his Sacro-Occipital research group on the East Coast, before the two parted ways in the late 1940s and he taught his own method. Over more than four decades he taught, by estimates in the specialist press, several thousand chiropractors and students — mostly single-handedly, outside the colleges. In 1986 he designated successors to carry on his work; he died in 1987 at the age of 83. DNFT is regarded as the origin of many later low-force methods in chiropractic.
