Pain Generator Detection
Sensitivity and Specificity in Detecting Pre-DRG Pathology
Evidence Based Medicine
The patented modulated Neural-Scan signal is designed to isolate specific types of sensory fibers. This is especially valuable in helping detect dysfunction in the A-delta fibers for evaluation of possible pre-DRG pathway pathology. Verification of firing is supported by the well documented fact that A-delta fibers are literally "hardwired" to the ventral motor pathway, so when they fire they not only produce a detectable action potential but additonally cause a subthreshold potential in the associated ventral motor pathway. Neural-Scan alone, or in conjunction with the potentiometer, can in a few minutes assess all the major nerve in a region to help detect the one or two requiring the highest voltage amplitude to initiate firing. Most important, the patient is his own control independent of age, gender or population data. As documented in medical text, conventional EMG/NCV cannot access the pain generating fibers of the pre-DRG in the absence of gross motor deficit, which is fairly rare, since most neck and back pain patient do not complain of, or demonstrate, weakness.
The Fallacy of Spontaneous Recovery
Based on the studies by Donelson et al. The Low Back Pain Experience: Natural History Survey - North American McKenzie Conf. Orando FL (2000) and Wayman et al. A Prospective Follow-Up Study of Low Back Pain in the Community - Spine 2000 that Though 40 - 50% of low back pain cases spontaneously recover within two weeks and 80 - 90% have recovered by two months, 60 - 90% suffer recurrences with progressively worsening, increased disability, longer duration and increasing peripheral radiation.
It would seem logical that the key is accurate diagnosis of the level and side of nerve root lesion so appropriate intervention can prevent recurrences and increasing disability. The Neural-Scan can be a valuable tool in this regard.
Fibromyalgia
The Neural-Scan has been shown to detect pre-DRG pathology in most of these patients and has been reported to allow successful treatment in many such cases.
Double Objective Proof
Preliminary findings support that pre-DRG pathology may have a close correlation with abnormal vertebral motion as viewed on A-P lateral bending x-ray. It is suspected that diminished proprioceptive sensory input can affect spinal motor function, which is well documented in Guyton & Hall, and other medical physiology textbooks, that the small intrinsic muscles of the spine are under major controlled on a level by level in the spinal cord. See Guyton & Hall 9th Edition Page 705

FDA Indications and Usage: The Neural-ScanTM NCSs is a diagnostic device that allows the quantitative detection of various sensory neurological impairments caused by various pathological conditions or toxic substance exposures. The subject population for whom this device can be used for diagnostic purposes includes any individual capable of communicating the perception of cutaneous sensation (with the potentiometer, which has a separate FDA clearance, the test is not dependent on the subject reporting perception of the cutaneous sensation, since the action potential of the nerve firing is detectable by the potentiometer). The Neural-ScanTM NCSs diagnostic examination may be conducted as part the neurological examination or for screening to detect peripheral neuropathies.
