PCCR, University of Iowa begin study on TMD

January 7, 2010 — Researchers at the Palmer Center for Chiropractic Research (PCCR), on the Palmer College of Chiropractic campus in Davenport, Iowa, are working in collaboration with the University of Iowa’s College of Dentistry and Institute for Clinical and Translational Sciences, to explore the feasibility of using chiropractic care to treat people with chronic pain in their face and jaw, classified as temporomandibular disorder (TMD).

The TMD study is one of three projects that are part of a four-year, $2.8 million grant awarded to the PCCR in 2008 from the NIH National Center for Complementary and Alternative Medicine to establish a multidisciplinary Developmental Center for Clinical and Translational Science in Chiropractic. The TMD study is directed by project co-leaders James DeVocht, DC, PhD, from Palmer, and Clark Stanford, DDS, PhD, from the University of Iowa.

One approach to relieving TMD pain is for chiropractors to provide a specific form of treatment, Activator Methods technique, using a hand-held mechanical device to deliver a quick, gentle adjustment in a precise manner to areas of the head and neck. The TMD component of the Activator approach was developed by Wally Schaeffer, DC, Coralville, Iowa, and has shown promise in an earlier case series.

For the current TMD study, potential participants will be interviewed by phone and given a dental examination at the Dental ClinicalResearch Center at the University of Iowa to determine if they qualify. A total of 80 participants will be enrolled and randomly assigned to one of four different treatment groups, all of which will include an intensive self-care program for TMD pain management.

Participants will be equally assigned to either: 1) Activator chiropractic care; 2) a conventional dental splint used for TMD management; 3) a placebo treatment; or 4) the intensive self care program alone. All participants will receive examinations and treatment at the Dental Clinical Research Center in Iowa City and patients assigned to chiropractic care will be referred to a private practice in Coralville, Iowa. Examinations and treatment are provided at no charge to participants.

The Palmer Center of Chiropractic Research will serve as the Data Coordinating Center for this study. Patients will be treated for two months and their progress followed for an additional four months.
