Advancing Knowledge Through Research

Palmer researchers impact patient care in profound ways.

From leading ground-breaking research to publishing relevant, accessible articles, faculty and staff at the PCCR remain dedicated to impacting patient care and policy through research, analysis and intelligence. The Palmer Center for Chiropractic Research (PCCR) is the largest chiropractic research center in the nation, conducting some of the largest chiropractic clinical trials in the world. The work at the PCCR last year focused on providing research experiences and training, strengthening partnerships and collaboration, publishing in relevant journals, meeting milestones of current projects and developing new projects.


Active Grants & Projects

Palmer Team Leads VERDICT Clinical Trial

The VERDICT trial, funded through a $7.1 million grant award from the National Institutes of Health (NIH), will address the pain and functional outcomes associated with different numbers of chiropractic visits delivered to veterans with chronic low-back-pain. This is the largest award ever granted by the NIH to a chiropractic institution. Researchers will implement the study at four VA sites in California, Connecticut, Iowa and Minnesota with a planned enrollment of 766 veterans.

Palmer Center for Chiropractic Research is leading the VERDICT clinical trial over the next four years. Collaborating institutions include the University of Iowa College of Public Health, Yale University Center for Medical Informatics, The Dartmouth Institute for Health Policy & Clinical Practice, and Spine IQ.

VERDICT is part of an $81 million federally-funded NIH-DoD-VA Pain Management Collaboratory which is an initiative supporting large-scale pragmatic clinical trials focused on the use of non-drug pain management approaches among active-duty and veteran populations. VERDICT is one of only 11 studies being conducted through the Collaboratory.


The Palmer Center for Chiropractic Research Concludes DoD-funded ACT Studies after eight years

The Assessment of Chiropractic Treatment for Low Back Pain, Military Readiness, and Smoking Cessation in Military Active Duty Personnel (ACT I, II and III) clinical trials have closed after eight years of hard work and collaboration. The ACT I study enrolled 750 active-duty military personnel at three military treatment facilities across the U.S. ACT II enrolled 120 Special Operations Forces military personnel and ACT III enrolled 110 active-duty military personnel. Study protocols and findings have been published with more to come in the following year.

Dr. Vining Named Academician of the Year

Robert Vining, D.C., D.H.Sc., professor and associate dean for clinical research with the PCCR was named Academician of the Year by the American Chiropractic Association. This annual award recognizes one individual for his or her efforts in advancing the profession through academic or educational excellence.

Dr. Vining was also named Faculty Member of the Year by Palmer College of Chiropractic. In calendar year 2018, Dr. Vining completed his Doctor of Health Sciences degree while serving as a generous mentor, presenter and teacher. He published 15 peer-reviewed articles, co-mentored three clinical research fellows and a post-doctoral research scholar, all while actively involved in several other key service activities.


Gallup-Palmer Year-Four Survey Results Published

In the fourth installment of Gallup-Palmer’s annual report, we unveiled new findings on Americans’ preferences for neck- or back-pain care, patient experiences with health-care providers and the prevalence of various methods for addressing this type of pain in the United States.

Key findings:

  • About two-thirds of U.S. adults (62%) have had neck or back pain significant enough that they saw a health-care professional for care at some point in their lifetime, including 25% who did so in the last 12 months.
  • A majority of U.S. adults have positive views of chiropractors. Sixty-three percent agree most chiropractors have their patients' best interest in mind.
  • For neck- or back-pain care, eight out of 10 adults in the United States (80%) prefer to see a health-care professional who is an expert in spine-related conditions.
  • Adults in the U.S. want more options available for neck- or back-pain care. Prescription pain medications are not preferred as a first step for care among the vast majority of U.S. adults.
  • Roughly nine out of 10 adults who saw a chiropractor most often for significant neck- or back-pain in the last 12 months say their chiropractor often listens (93%), provides convenient, quick access to care (93%), demonstrates care/compassion (91%) and explains things well (88%).
