Seven neurodiagnostic modalities are presented with complete explanations of the language of the neurosciences. The modalities include needle-electromyography, short latency somatosensory evoked response, motor conduction velocity and sensory nerve action potential studies, F-response and H-reflex studies, and electroencephalography. These neurodiagnostic studies are correlated with clinical chiropractic diagnostic expediency and specificity. Finally, the article demonstrates practical and efficient methods of cooperation between neurologists and the referring chiropractic physician that has eluded these professions for almost a century.
