In a ground-breaking study, medical and chiropractic researchers are joining efforts to study the effects of a form of non-surgical treatment for neck pain, more specifically Cox distraction manipulation. This study is one of three projects that are part of a four-year, $2.8 million grant awarded in 2008 to the Palmer Center for Chiropractic Research (PCCR), headquartered on the Palmer College of Chiropractic campus in Davenport, Iowa.
