In normal subjects DCV showed the unimodel normal distribution. In the diseased subjects, DCV showod polymodel distribution and/or the prolonged velocity range. In ALS MCV study showed the abnormal findings in 19 of 25 patients and DCV study revealed the abnormal findings in 24. In polyneuropathy except for chronic demylinating polyneuropathy (CIDP) MCV study showed abnormal findings in 14 of 18 patients, and DCV study did in all patients. In CDP both MCV and DCV studies showed the abnormlity in all the patients. In some of the patients the DCV clarified the abnormal conductivities in spite of the normal MCV study. DCV study is more sensitive in detecting the abnormal conductivities of motor fibers than the conventional MCV study, and useful to evaluate the pathophysiological process of diseased motor nerve fibers.}, pages = {384--400}, title = {末梢神経疾患における運動神経伝導速度分布の検討}, volume = {109}, year = {1995} }
