Parker Research Institute
One of the most important elements of clinical research involves the successful recruitment of patients. Previous studies of chiropractic practices reveal that word-of-mouth and patient referrals are superior methods of advertising. A similar trend is often observed in the recruitment of patients for clinical trials.

In an effort to gain greater public exposure and establish a positive rapport with the community, researchers at the Parker Research Institute devote a significant portion of their time to various community health events/projects and organizations. Patients are not only presented with the opportunity to participate in research that might be of importance to them, but they become educated about chiropractic wellness and the benefits of chiropractic care to their overall health and well being.

Perhaps the motivation to make a difference in the lives of community members may best be described in a thank you letter from a former patient, “It pleases me to just be noticed and considered.”

Working with Others Nationally and Internationally

A significant portion of research conducted at the Parker Research Institute has been made possible through collaborations with various educational institutions and organizations across the U.S. and abroad. These collaboration efforts add diversity and specialized expertise to our research projects, greatly influencing the quality of research produced at the Parker Research Institute.
