To the Editor:—  In The Journal, July 16, under Correspondence, a "correction" was suggested for our paper, "Clinical Value of Motor Nerve Conduction Velocity" (J. A. M. A., April 30, p. 2030), by Dr. Robert Hodes, of one of the references we quoted. During our study, we thoroughly reviewed Hodes' published work and have gained much from it. However, it has been shown since this study that the conduction velocity is normal in poliomyelitis.1-3Unfortunately, Dr. Hodes apparently did not consider the effect of the reduced temperature on the conduction velocity in the paretic limbs of poliomyelitic patients. We have found a reduction of the conduction velocity of 5% per degree Centigrade. This is of the same order of magnitude as others have reported (Lambert 2.4 M/s per degree Centigrade).1 Trott and co-workers4 demonstrated the reduction in temperature of the paretic limb in poliomyelitis.
