Guest guest Posted May 13, 2004 Report Share Posted May 13, 2004 Docs, Here is Croft's treatment schedule for auto trauma: Also, you can go to www.chiroweb.com and type in "Croft". You will find a ton of articles he has written. Matt Terreri, DC MVAs and MMI: How Much Is Enough? For many of us, the issue of maximum medical improvement (MMI) is a true conundrum. This is particularly so in motor vehicle accidents (MVAs) where our patients have often been injured by a negligent driver. In the interest of fairness it would seem most reasonable to allow for indefinite treatment of an injured victim if necessary. In the real world, however, practicality dictates that at some point we make a declaration of MMI. This allows any legal remedy to come to a conclusion and all debts to be (hopefully) paid. Any awards bestowed upon an injured party should take into account the need for future medical or chiropractic care. Patients can also be treated under general health insurance policies in many cases. Some have suggested using the term "maximum chiropractic improvement" instead of "maximum medical improvement." The difference seems nebulous to me since it presumes that patients treated by chiropractors and medical doctors improve to different degrees, and that has yet to be established (although research is currently under way). In certain settings, a certain amount of ambiguity is allowed anyway. I am a state-appointed independent medical examiner, for example. I believe the best approach to arriving at MMI is the following: First, grade the severity of the patient's trauma using the severity scale of the SRISD classification of cervical acceleration/deceleration (CAD) trauma,1 Table 1. Next, use the potentially complicating factors in Table 2 as a guide to modify the figures in Table 3 to arrive at a reasonable treatment frequency and duration. For example, in a patient categorized as Grade III with one or two moderate complicating factors, the treatment duration will average about 56 weeks (shorter with no complicating factors and longer with more complicating factors or more severe complications). Finally, refer to Table 4 to determine MMI. Beyond the active treatment period as suggested by Table 2, after three consecutive monthly re-exams with no further significant objective improvement (range of motion, trigger points, muscle strength, gait, antalgia, orthopedic/neurologic/radiographic signs), you should consider the patient MMI. Gradual further subjective improvement is variable. References Croft AC: Whiplash: the Master's Program. Module I, Whiplash, an Overview. Coronado, Spine Research Institute of San Diego, p 73, 1992.

Dynamic ChiropracticJuly 31, 1992, Volume 10, Issue 16 Printer Friendly VersionEmail to a Friend I would like to thank Arthur C. Croft, DC, MS, MPH, FACO, FACFE, FAAIM for the generous contribution of these 6 tables from the 12th chapter of his text Whiplash Injuries: The Cervical Acceleration/ Deceleration Syndrome. To the best of my knowledge, this is the only on-line source of well documented treatment guidelines for the whiplash patient, which actually suggests the number of treatments which may be necessary. Please refer to Dr. Croft's text (3rd edition, 2001) for further explanation. You might also enjoy some of Dr. Croft's articles and his November 15, 2000 article, referring to these guidelines, titled Guidelines for the Management of CAD Trauma.
