I was able to take only a few of the Carrick neurology course modules after which I was forced to continue my studies through study of texts and audio recordings of past module lectures which the Carrick Institute sells. I always found it strange and unfortunate that a formal text for the Carrick course did not exist because, although academic neurology texts provide the basis for clinical application, they almost always stop short of actually delineating such application. I was therefore elated when I finally chanced upon the so called, "Functional Neurology for Practitioners of Manual Therapy"; I bought it expecting that the author, schooled by Dr. Carrick himself and with so many hard-earned "I-am-great" letters flowing after his name, would have the professional self-assurance, as a chiropractor, to offer instruction to other chiropractors with a view to improving the lives of the patients. Instead, I found chapter after chapter, followed by chapter questions and answers, evidently dedicated more to attempting to impress the medical profession with the author's neurology acumen than with guiding chiropractic clinicians in the application of academic principles. I bought the text hoping to find instruction to become a more adept clinician, to augment my ability to improve the lives of my patients; attempting to justify my professional existence before other professions and to impress them with my academic knowledge in their fields never entered into my motivation.
I have to say that I was surprised by the glaring error on page 93 in which the author explains the nerve tract of CN VII and the signs and symptoms associated which lesions at the upper and lower motor neuron levels. The diagrammatic representation is correct, with the superior face receiving both ipsilateral and contralateral cortical efferent innervation and the inferior face receiving only contralateral cortical innervation. The subtext to the diagram however has a couple of errors: the first involves the statement that the lower face receives Facial N. cortical input from the ipsilateral cortex when, indeed it is from the contralateral side; the second error involves the statement about upper motor neuron lesions, to the cortical efferents to the Facial nuclei, resulting in spastic paralysis of the contralateral superior face only, when, in fact, the superior contralateral face is spared any deficit in such a scenario because of bilateral cortical input. Specifying superior or inferior, right or left, ipsilateral or contralateral etc. may seem like minor "typos" to many but it is critical in neurology and I am confidant the author knows it. It's beyond me how mistakes of this nature could have passed unnoticed in the editing process; it unfortunately casts doubt on the reliability and accuracy of the rest of the academic information presented.
In short, the work is a severe disappointment because there is such a crying need for a text of clinical application of the principles of chiropractic neurology and the author appears to be eminently qualified to produce such a guide, he is clearly in possession of an encyclopedic understanding of the topic. In the end, however, the text is nothing more than an extensive regurgitation of academic neurology, albeit presented in a chiropractic context; it fails to deliver on the promise to guide practitioners of functional neurology.
