Acceptance by National Guideline Clearinghouse ensures worldwide distribution and accessibility.

The National Guideline Clearinghouse (NGC), a comprehensive database of evidence-based clinical practice guidelines accessible via the Web, has accepted diagnostic imaging guidelines developed recently to "assist chiropractors and other primary care providers in decision-making on the appropriate use of diagnostic imaging for specific clinical presentations." The guidelines were published in the Journal of Manipulative & Physiological Therapeutics (JMPT) in 2007-2008.1-3
"The guidelines aim to describe appropriate care based on the best available scientific evidence and broad consensus, reduce inappropriate variation in practice, and provide a more rational basis for referral," said Andre Bussieres, DC, FCCS (C), MSc, primary author of the guidelines. "We are very pleased to announce that [they] were recently posted on the [NGC Web site]." He added: "This is important news for all chiropractors aiming to improve patient care while potentially reducing harm."4
A November/December 2007 JMPT article provides a comprehensive introduction to the guidelines, including the process that led to their development.5 It states: "The initial impetus for this project occurred in 2003 when the Council on Chiropractic Education in Canada (CCEC) requested a revision of the diagnostic imaging guidelines used at the chiropractic teaching clinic of L'Universite du Quebec a Trois-Rivieres (UQTR). CCEC recommended incorporating protocols that were centered on the clinical presentation of patients. ... The proposed diagnostic imaging guidelines represent a shift to a more evidence-based approach and are supported by more than 680 primary and secondary citations."
According to Dr. Bussieres, a professor in the chiropractic department at UQTR, the guidelines, which attempt to prevent "overuse, underuse and misuse" of imaging services and improve quality of care, address common clinical scenarios, such as nonspecific acute, subacute or persistent back and neck pain with normal neurologic examination (for which radiographs are not initially indicated), to cases of blunt trauma with no improvement after four to six weeks of conservative care or increasing disability, for which X-rays should be considered. He also notes cases in which urgent specialized imaging should be considered, such as signs/symptoms of sphincter or gait disturbance, saddle anesthesia, severe neurologic deficit, and systemic illness.4
Dr. Bussieres also mentioned that implementation studies are currently underway to see gauge what impact the guidelines are having on provider behavior.

While there may be no “magic bullet” when it comes to health, this should not dissuade patients or practitioners from seeking out ingredients that offer multiple health benefits. When it comes to dietary supplements, there are thousands upon thousands of choices. So, why not choose one that can address pain and assist with mental health? A supplement that can address inflammation, while also preventing certain types of cancer.
This article focuses on nine severe injuries that are generally not diagnosable until the third to fourth week following the date of injury, including how to diagnose these severe injuries. The discovery of any of these injuries early can make a significant difference in the case outcome.
While canes, braces and posts represent extrinsic methods for lessening adductor moment arms, an intrinsic method for lessening the development of medial knee osteoarthritis occurs when the hip abductor musculature and the iliotibial band are strong enough to create a compressive force capable of stabilizing the lateral knee.
