Neuromechanical News for June 12, 2001 Subject: Reflexes in Whiplash Injury Demonstrate Underlying Mechanism of Post-Traumatic Headache Dear Doctors: Last weekend, we finished the last of our Spring seminars in San Francisco and before I discuss this week's article, I want to reflect on the season and give you some insight as to the future. As in any new start-up, it was a major challenge, but yet came to be a great sucess. I feel very fortunate to have the support of so many of you who turned out to spend a weekend of your life with me in 12-hours of post-graduate education. We certainly had fun while we studied together. For those of you who haven't made it to a seminar yet, check the website to see " what others are saying, " and be sure to look for us this fall. We are just now completing our fall schedule and we will again be going coast-to-coast with this exciting new program - A Neuromechanical Approach to Chiropractic. In addition to appearances for other conventions, this summer I will lecture outside of London July 14-15, so any of you who would like to travel to Europe this summer, this may be a great opportunity to do so and study at the same time! I have also spent the last number of months working on our new video/Interactive CD-Rom series " Understanding Chiropractic " which will debut this fall. Broken down into the most pertinent subjects you as a DC want to address, this series will enable you to not only self-study the most up-to-date chiropractic effectiveness and rationale studies availble, but place it in your hands in a very user friendly and applicable manner for you to take public - to other physicians, industries, and patients. All good things take time, and I can assure you that this program is well worth the wait. In other news, one of our vendors, J-Tech Medical, has packaged " The Colloca Tracker System " (I asked them to call it the Neuromechanical program, but they chose Colloca ... just for those of you who think that I came up with the name) This completely computerized system is both reliable and valid with Range of Motion assessment utilizing Dual Inclinometry (to meet the AMA Guidelines) and Pressure Algometry (Based on Fischer's Protocols)! We developed this system for true, evidence-based diagnostics. With the click of a button, reports and graphs are quickly generated for bullet-proof documentation for both patients and payors. The benefits are endless. Doctors can also add muscle strength testing, grip, and pinch strength dynamometry to our modulated system .... simply adding on as they go... and wait till you see what we are bringing to the table in the very near future! Visit the website for more info on this fabulous system! Last, as many of you know, for the past several years, I have collaborated with Dr. Tony Keller, professor and interim Chair of the Department of Mechanical Engineering at the University of Vermont. In much of the work that we did, Dr. Keller and I were supported by the National Institute of Chiropractic Research, a non-profit organization. This year, after asking for continued support in January, Dr. Keller and I have just been informed that the NICR did not have funding available for the projects that we proposed. Inasmuch, we are seeking financial support from other funding agencies and private contributions from doctors like yourself. In the past 4 years, Dr. Keller and I have completed 16 peer-reviewed research papers/conference presentations and currently we have an additional 7 studies in progress. The opportunities that we now have include investigating the anti-nociceptive effects of adjustments and the ability of adjustments to inhibit hyperactive paraspinal muscles. These projects, by far to date will represent our most important work. Dr. Keller and I will be collaborating this summer here in Phoenix continuing our longitudinal data draw on patients in this office as well so that we may document the benefits of chiropractic care. I will be in contact with you about how you can help keep this important research agenda going, and in the meantime, if you have any ideas or contacts, please don't hesitate to let me know. Now, on to this week's article! We have heard alot about the recent Duke University review on effective treatments for headache. In this meta-analysis, Chiropractic care was clearly shown to be effective in the management of some types of headache - a message that you should be taking to your patients and to the public! But how are these headaches caused? What associations may lead us to believe that chiropractic care would be the most rational intervention in these types of cases? A new study published in the June iss ue of the Journal, Pain, investigates the anti-nociceptive reflex alteration in post-traumatic headache patients. In this work, researchers from the Department of Neurology, at the University of Essen, in Essen, Germany measured temporalis muscle reflexes in post-injury patients demonstrating maked differences from normal subjects. With the new research available that demonstrates the convergence of nociceptive signals on the trigeminocervical nucleus as being causitive in cervicogenic headache generation, one can add this research to the existing base of knowledge that demonstrates a clear physiological basis for the symptoms that our patients present with. Just how chiropractic care influences these reflexes is one of my great interests. On that note, see below for the full citation and abstract of this research. Finally, on the subject of reflexes, I want to congratulate my friend, Dr. Don Dishman, from the reseach department at New York Chiropractic College in winning the Haldeman Award at the recent World Federation of Chiropractic Congress in Paris. Dr. Dishman's paper continuing his work in understanding reflex responses to spinal manipulation is not only very well done, but is now making NYCC a major player in the chiropractic research arena! Great job, Don! _______________________________________ Keidel M, Rieschke P, Stude P, Eisentraut R, van Schayck R, Diener H. Antinociceptive reflex alteration in acute posttraumatic headache following whiplash injury. Pain 2001 Jun;92(3):319-26. Brainstem-mediated antinociceptive inhibitory reflexes of the temporalis muscle were investigated in 82 patients (47 F, 35 M, mean age 28.3 years, SD 9.4) with acute posttraumatic headache (PH) following whiplash injury but without neurological deficits, bone injury of the cervical spine or a combined direct head trauma on average 5 days after the acceleration trauma. Latencies and durations of the early and late exteroceptive suppression (ES1 and ES2) and the interposed EMG burst (IE) of the EMG of the voluntarily contracted right temporalis muscle evoked by ipsilateral stimulation of the second and third branches of the trigeminal nerve were analyzed and compared to a cohort of 82 normal subjects (43 F, 39 M, mean age 27.7 years, SD 7.1). Highly significant reflex alterations were found in patients with PH with a shortening of ES2 duration with delayed onset and premature ending as the primary parameter of this study, a moderate prolongation of ES1 and IE duration and a delayed onset of IE. The latency of ES1 was not significantly changed. These findings indicate that acute PH in whiplash injury is accompanied by abnormal antinociceptive brainstem reflexes. We conclude that the abnormality of the trigeminal inhibitory temporalis reflex is based on a transient dysfunction of the brainstem-mediated reflex circuit mainly of the late polysynaptic pathways. The reflex abnormalities are considered as a neurophysiological correlate of the posttraumatic (cervico)-cephalic pain syndrome. They point to an altered central pain control in acute PH due to whiplash injury. Until next time, Colloca, D.C. P.S.
