Larry Webster
The Children's Chiropractor
Larry Webster (1937 to 1997) founded the International Chiropractic Pediatric Association and created the Webster Technique. A 1959 Logan graduate, he practiced twenty years in Missouri, then ran the clinic at Life Chiropractic College in Marietta, Georgia. He built his sacral analysis in 1976 for his own daughter's labor. The organization he founded now defines the technique without reference to fetal position. The Unified Model of Tone reads his protocol as one claim: create the conditions and stop, because the body does the rest.

Twenty years in Missouri
Larry Webster built his method inside a twenty-year Missouri family practice
Larry Webster graduated from Logan Chiropractic College in 1959, opened a family practice in Missouri, and stayed about twenty years. He taught nothing outside that town until the middle 1970s. Claudia Anrig's memorial column in Dynamic Chiropractic, published in March 1997 weeks after Webster died, is the fullest surviving account of those years. It records a doctor still making house calls, and staying through the night to adjust a sick child.
One ICPA document gives Webster a birth year its own text rules out
Two birth years circulate for Larry Webster, and a single source settles the question against itself. The ICPA's 2012 technique paper heads its abstract with the dates 1945 to 1997. Four pages later the same paper states that Webster graduated from Logan College of Chiropractic in 1959, which a man born in 1945 would have done at fourteen. Anrig's column calls him a chiropractic veteran of thirty-eight years, and 1997 minus thirty-eight is 1959. The ICPA's own biography of its founder gives 1937 to 1997, and that is the year the record supports.
House calls came first, and the specialty came out of them
Webster treated whole households. Anrig records him caring for pregnant women across the length of their pregnancies, and being the first person in his community to adjust many newborns. That practice ran from 1959 until roughly 1979. The pediatric specialty Webster formalized after 1986 is the same work, written down and taught to other people.
A birth in 1976
Webster built his sacral analysis in 1976 for his own daughter's labor
Webster's daughter Lucinda had a hard labor in 1976, and the Webster Technique came out of it. The ICPA's account of its founder names the year and the people. Webster set out to build an adjustment for laboring women, so his granddaughter Shannon would have an easier birth than her mother did. What he produced was a pair: an analysis that names the problem, and an adjusting protocol that addresses it.
The procedure is an analysis first and an adjustment second
Webster's method begins with a check. The chiropractor flexes both knees with the patient prone and brings each heel toward the same side buttock. One side resists, and that asymmetry names the side. The adjustment is a low force posterior to anterior contact at the sacral notch, just lateral and inferior to the second sacral tubercle. Webster named a drop piece as the preferred delivery, so the table supplies the amplitude the hand does not. In the female patient a sustained soft tissue contact on the opposite round ligament follows. The full procedure is set out on the Webster Technique page.
Webster's first published account appeared in 1982
Webster published "Chiropractic care during pregnancy" in Today's Chiropractic in 1982, at pages 20 to 22. Jeanne Ohm and Joel Alcantara list it first among the technique's sources thirty years later. Anrig's column records that Webster had taught the procedure for two decades by the time he died, which places the teaching in the late 1970s. The 1976 origin sits inside a family, and the 1982 publication is where a private adjustment became a taught procedure.
Webster taught the analysis for every weight bearing person
Webster taught the sacral analysis and adjustment for all weight bearing individuals, pregnant or not, female or male, adult or child. Ohm and Alcantara record that scope in the ICPA's governing paper. The pregnant pelvis is the most common reason to use the method and the setting it is taught in most often. The subject of the procedure is the sacrum, and pregnancy is the condition under which a distorted sacrum costs the most.
Three names, one procedure
The organization Webster founded removed fetal position from the definition of his technique
The Webster Technique carried three names, and the International Chiropractic Pediatric Association retired two of them by 2000 because both named a condition in the fetus. Ohm and Alcantara set out the sequence in the ICPA's 2012 paper. Pregnant patients under care with breech presentations reported that their babies had turned, and patients and chiropractors alike began calling the method a breech turning technique. Jennifer Brandon Peet's Chiropractic Pediatric and Prenatal Reference Manual described it that way in its 1992 second edition. Anrig in 1993, and Forrester and Anrig in 1998, described it as an in-utero constraint technique.
The 1999 certification class came first, and by 2000 the words were gone
Connie Webster, Webster's widow and then the ICPA's executive director, implemented the ICPA Webster Technique Proficiency Certification class in 1999 with Jeanne Ohm. By the following year the terms breech and in-utero constraint had been eliminated from the language describing the method. Anrig's column two years earlier had still named it the Webster in-utero constraint procedure. The whole change happened within three years of Webster's death.
The stated reason is scope of practice
The ICPA's reason concerns what a chiropractor is licensed to treat. Both retired terms named a condition in the unborn child. Care named for a fetal condition describes itself as treatment directed at the fetus, which is obstetrics. The Webster Technique is directed at sacral subluxation in the mother. The same paper declines to endorse Leopold's maneuver as part of the Webster protocol, because palpating to determine fetal lie is an obstetric assessment.
What the ICPA publishes now
The definition the organization publishes names an analysis, an adjustment, a joint, and a region. It stops there. It says nothing about a fetus. Ohm and Alcantara published the wording on May 10, 2012 in the Journal of Pediatric, Maternal and Family Health, and the ICPA has held it since.
The Webster technique is a specific chiropractic analysis and diversified adjustment. The goal of the adjustment is to reduce the effects of subluxation and/or SI joint dysfunction. In so doing neuro-biomechanical function in the sacral/pelvic region is improved.
International Chiropractic Pediatric Association, governing definition, published by Jeanne Ohm and Joel Alcantara, May 10, 2012Connecticut, 1986
A proposed Connecticut law produced the International Chiropractic Pediatric Association
A 1986 Connecticut bill would have barred chiropractic care for any child under twelve years of age unless the chiropractor held a pediatric certification, and no such certification existed anywhere in the profession. Webster founded the International Chiropractic Pediatric Association that year. The Connecticut law never passed. The organization built to answer it outlived him by decades.
Webster answered the bill by writing a curriculum
The ICPA became the first body in the profession to run a pediatric certification program, and it ran to a hundred accredited hours by the time Webster died. Anrig's column credits it with two more firsts: a newsletter for members, and the annual Pediatric Extravaganza. That program has since grown into the ICPA's 180-hour certification, with the Webster Technique certification sitting inside it as one component.
Membership from 1997 to 2024
The ICPA had more than a thousand members when Webster died in February 1997. Ohm and Alcantara reported over three thousand members worldwide in 2012. The organization's own magazine, Pathways to Family Wellness, put the figure near nine thousand in its 2024 account of the ICPA's origin. Webster built the institution in the last eleven years of his life.
Marietta, Georgia
Webster directed the clinic at Life Chiropractic College and taught its pediatrics for eleven years
Webster directed the clinic and taught pediatrics at Life Chiropractic College in Marietta, Georgia. He kept a private practice inside that clinic, so students watched him work. The college was chartered on September 12, 1974 by Sid Williams, and it welcomed a first class of twenty-two students to the Marietta campus on January 20, 1975. Webster arrived a decade later and stayed until he died.
Students saw the difficult cases in the room
The clinic arrangement put Webster's hardest cases in front of a classroom. He was the chiropractor for many female students and for the wives of students through their pregnancies, and Anrig credits him with being the first to adjust hundreds of newborns. Her column also credits him with influencing thousands of chiropractic students across that decade. The pediatric curriculum in this library covers the same developmental ground.
Webster invented the pediatric toggle headpiece board
Webster built equipment. He invented the pediatric toggle headpiece board and supplied design ideas to the companies manufacturing chiropractic tables. At his death he had a new headpiece design on the drawing board, meant to improve the delivery of an adjustment to a child's spine. The instrument problem he was working on is the one every pediatric adjusting method has to solve: how to scale a contact to a body that weighs a few kilograms.
Logan gave Webster the sacrum
Webster's sacral emphasis came from the school that trained him. Logan Chiropractic College was built around Hugh Logan's basic technique, whose primary contact is a sustained light pressure at the sacrotuberous ligament. Ohm and Alcantara cite the Textbook of Logan Basic Methods in their 2012 paper, and they record that Logan practitioners knew Webster held the correction of sacral subluxation to be central. The Logan Basic page covers that contact in full.
Chiropractic today for a better world tomorrow.
Larry Webster, DC, as recorded by the International Chiropractic Pediatric AssociationTestimony, 1979
Webster testified as an expert in Wilk v. AMA in 1979
Webster gave expert testimony in the antitrust case that decided how the profession could practice. Chester Wilk and four co-plaintiffs had filed against the American Medical Association in 1976, and the litigation ran for more than a decade. Anrig's column records Webster testifying in 1979, seven years before the ICPA existed and while the profession still had no pediatric credential of any kind.
Webster testified in trials concerning children
Courts called Webster because few others could say what qualified a chiropractor to treat a child. Anrig records that he made himself available to colleagues who needed testimony in trials concerning children. That is the gap the ICPA was built to close, and the certification program answered it seven years later.
The 20/20 broadcast put Webster on camera for the profession
Anrig's column records that a 20/20 television segment was intended to damage the profession's standing, and that Webster made himself solely responsible for appearing on its behalf. He used the airtime to describe the growing demand for family chiropractic care. Anrig calls him the profession's leader and hero in that segment.
The dated record
The dated record of Larry Webster's career
Only Webster's birth year is contested. Every other date below is fixed by a document, and the document is named with it.
1937 to 1959, birth and Logan
Webster was born in 1937, on the ICPA's own biography of its founder. He graduated from Logan Chiropractic College in 1959, a date the ICPA biography and the 2012 Ohm and Alcantara paper both give. Anrig's thirty-eight-year career length, published in March 1997, produces the same year independently.
1976 to 1986, a birth, a courtroom, and a bill
Webster's daughter Lucinda gave birth in 1976, the origin of the sacral analysis, on the ICPA's account. He gave expert testimony in Wilk v. AMA in 1979, per Anrig. He published "Chiropractic care during pregnancy" in Today's Chiropractic in 1982, cited first in Ohm and Alcantara's reference list. In 1986 he founded the International Chiropractic Pediatric Association, in response to a proposed Connecticut law restricting chiropractic care for children under twelve.
1992 to 1997, the manual and the last year
Peet's Chiropractic Pediatric and Prenatal Reference Manual described the method as a breech turning technique in its 1992 second edition, at page 208, per Ohm and Alcantara's citation. Webster died on February 7, 1997 in Atlanta, Georgia, a chiropractic veteran of thirty-eight years, per Anrig. Her column lists the survivors: his wife Connie, his daughters Pam and Lucinda, two stepsons, five grandchildren, and one great-grandchild.
1999 to 2012, the certification and the definition
Connie Webster and Jeanne Ohm implemented the ICPA Webster Technique Proficiency Certification class in 1999, per Ohm and Alcantara. By 2000 the terms breech and in-utero constraint had been eliminated from the ICPA's description of the method. On May 10, 2012 the same two authors published the governing definition in the Journal of Pediatric, Maternal and Family Health, naming an analysis, an adjustment, a joint, and a region.
Webster in the journals
The Webster Technique entered the indexed literature five years after Webster died
Richard Pistolese published the first PubMed-indexed paper on the technique in 2002, in the Journal of Manipulative and Physiological Therapeutics, volume 25, issue 6. He mailed surveys to 1,047 United States and Canadian members of the ICPA. One hundred eighty-seven came back, a return rate of 17.86 percent, and 112 met the inclusion criteria. One hundred twelve chiropractors in one organization were using a sacral analysis a dead man had taught them, which is what transmission looked like before the literature caught up.
The ICPA's practice-based research network
The ICPA now collects data from working practices. Joel Alcantara and colleagues studied 126 chiropractic patients under care with the Webster Technique and published in Complementary Therapies in Clinical Practice in 2016. Mean age was 39.68 years and the visit-specific satisfaction score averaged 93.4 percent. A larger cohort followed in 2018 in the Journal of Alternative and Complementary Medicine. It covered 343 pregnant patients of average age 30.96 years, entering care at a mean of 25.67 weeks of gestation, with satisfaction rising across the course of care at p less than 0.005.
What the pelvic literature measures
The variable Webster's check reads has been measured directly. Leonoor Damen and colleagues assessed sacroiliac joint laxity by Doppler imaging of vibrations in 163 women at 36 weeks of gestation, reported in Acta Obstetricia et Gynecologica Scandinavica in 2001. Average laxity did not separate the painful pregnancies from the comfortable ones. The left to right difference did. Asymmetric laxity appeared in 37 percent of the 73 women with moderate to severe pelvic pain and in 4 percent of the 90 women with none or mild.
Asymmetry predicts what happens after the birth
Damen's group followed the finding forward. A prospective cohort of 123 women, measured at 36 weeks of gestation and again at 8 weeks postpartum, appeared in Spine in 2002. Among women with moderate to severe pregnancy-related pelvic pain, asymmetric sacroiliac laxity predicted pain persisting into the postpartum period in 77 percent of cases. Specificity was 83 percent. Asymmetric laxity during pregnancy carried a threefold higher risk of pain that did not resolve.
How common the problem is
Wu and colleagues reviewed prevalence in the European Spine Journal in 2004. They put pregnancy-related pelvic girdle pain or low back pain at about 45 percent of pregnant women and 25 percent of women postpartum. Serious pain occurs in about 25 percent during pregnancy, and severe disability in about 8 percent. After pregnancy the problem stays serious in about 7 percent.
How far the pelvis moves
Reitter and colleagues measured the pelvis itself by MRI pelvimetry in 50 pregnant and 50 nonpregnant women, published in the American Journal of Obstetrics and Gynecology in 2014. Average transverse diameters ran 0.9 to 1.9 cm wider in a kneeling squat than in a dorsal supine position, a gain of 7 to 15 percent. In the pregnant group the bispinous diameter rose from 12.6 cm to 14.5 cm on a change of position alone.
Chiropractic care during pregnancy, reviewed
Kent Stuber and Dana Smith reviewed the published evidence on chiropractic care for pregnancy-related low back pain in the Journal of Manipulative and Physiological Therapeutics in 2008. Six studies met inclusion, covering January 1982 to July 2007, and all six reported positive results. Stuber, Wynd and Weis then searched the safety record for Chiropractic and Manual Therapies in 2012. Across the literature from 1978 to 2009 they identified five articles reporting adverse events in seven subjects.
Create the conditions and stop
Larry Webster built a procedure that creates the conditions and stops
The Webster Technique and the Unified Model of Tone make the same claim: create the conditions and stop, because the body does the rest. Webster checks, adjusts once, holds a ligament, rechecks, and stops. What patients then reported is what made the method famous in the 1980s, and it is also what attached two wrong names to it.
The pelvis Webster adjusted is a tension network
The uterus sits inside a tension structure. Its internal dimensions are set by the sacroiliac joints, the pubic symphysis, the round and broad ligaments, and the pelvic floor. Reitter's 0.9 to 1.9 cm of extra transverse diameter from a change of position is what a tensioned structure does when its configuration changes. The model reads that arrangement as biotensegrity, where compression elements float inside a continuous tension field and no element is loaded on its own.
Sacral posteriority is a reading of asymmetric tone
Webster's heel to buttock check measures how much resistance the tissue on each side offers to the same imposed movement, and reports the difference. The model names that difference tone asymmetry across the two halves of the pelvis. Damen measured the same variable with Doppler imaging and found it separated the painful pregnancies from the comfortable ones. What Webster's check reads is the body's own report of its state, one side against the other.
Create the conditions and stop, because the body does the rest
Webster set out to make labor easier by balancing a pelvis, and he stopped at the pelvis. The model holds the same position on every input. An input does not create an outcome. An input meeting a particular tone creates an outcome, and the practitioner's work is to deliver a signal the system can use. The tone the input meets decides what follows, which is why one procedure transforms one pregnancy and changes nothing in another.
Correspondence beats magnitude
Both halves of Webster's procedure are small. The sacral thrust is a shallow posterior to anterior impulse delivered through a drop piece. The round ligament contact is a sustained pressure held for one to three minutes. Neither is strong. The model holds that the active ingredient in any input is correspondence to the place the body is actually holding tension, rather than force at the place that hurts. The check carries the precision, and the contact that follows is shallow and brief.
What the model predicts about the space
The model predicts that reducing asymmetric pelvic tension expands the space available inside the uterus, and that a fetus repositions when the space permits a different configuration. The test is specific. Measure pelvic tension asymmetry before and after an intervention that targets it, blind the assessor to fetal position, and treat the change in asymmetry as the mediator. Damen's Doppler protocol already measures that mediator, in 163 women at 36 weeks of gestation.
Webster chose the earliest point in a life
Webster's other contribution is where he chose to work. The developing nervous system builds its regulation in a sequence, and the earliest inputs land on a system with the fewest established patterns to overwrite. Webster taught that the body of a child and the body of a pregnant woman are their own subjects rather than smaller versions of an adult. The model reads that as a claim about time course: one input carries a different consequence depending on when in a life it arrives.
Common questions
Common questions about Larry Webster
Who was Larry Webster?
Larry Webster was an American chiropractor, born in 1937 and a 1959 graduate of Logan Chiropractic College. He practiced about twenty years in Missouri, then directed the clinic and taught pediatrics at Life Chiropractic College in Marietta, Georgia. He created the Webster Technique in 1976 and founded the International Chiropractic Pediatric Association in 1986. He died on February 7, 1997 in Atlanta, Georgia.
When was Larry Webster born, and why do two years circulate?
The 1937 date is the one the documents support. The International Chiropractic Pediatric Association's biography of its founder gives 1937 to 1997. The ICPA's 2012 technique paper heads its abstract with 1945, then states four pages later that Webster graduated from Logan in 1959, which a man born in 1945 would have done at fourteen. His 1997 memorial column describes a chiropractic veteran of thirty-eight years, and 1997 minus thirty-eight is 1959.
Did Larry Webster invent the Webster Technique to turn breech babies?
Webster built the technique in 1976 to make his daughter's next labor easier by balancing the pelvis. Patients and chiropractors attached the breech language later, because women under care reported that their babies had turned. The International Chiropractic Pediatric Association, which owns the definition, eliminated the terms breech and in-utero constraint by 2000 and defines the method as a sacral analysis and diversified adjustment. Webster taught it for every weight bearing person.
Why did Larry Webster found the ICPA?
A 1986 Connecticut bill would have barred chiropractic care for any child under twelve unless the chiropractor held a pediatric certification, and no such certification existed. Webster founded the International Chiropractic Pediatric Association that year and built the profession's first pediatric certification program, a hundred accredited hours by the time he died. The Connecticut law never passed. The ICPA had more than a thousand members within eleven years.
Where did Larry Webster teach?
Webster taught at Life Chiropractic College in Marietta, Georgia, the school Sid Williams chartered on September 12, 1974. He directed the clinic and taught the college's pediatrics for eleven years, keeping a private practice inside the clinic so students could watch him work. He was the chiropractor for many students and students' wives through their pregnancies, and he was often the first to adjust their newborns.
What did Larry Webster contribute to the understanding of tone?
Webster built a procedure that creates conditions and then stops. He checks the pelvis for a side to side difference, delivers one shallow sacral contact and one sustained ligament hold, rechecks, and finishes. The Unified Model of Tone holds that an input meeting a particular tone creates an outcome, so the tone decides what follows. Webster's asymmetry check reads that tone directly, and his restraint after the input is the model's whole position on intervention.
