Dear Drs. Lawrence and Locke:
I read with a great deal of interest your article, "Motor Nerve Conduction Velocity in Diabetes" which was published in the November issue of the Archives of Neurology. As you know, we have been very interested in this for several years and I see you quoted us in our study which was published in Diabetes a year ago. I was very impressed with your approach to the subject but I felt that your conclusions may be in error because of two potential sources of error. The first is the variations in sweep speeds the Meditron electromyograph may demonstrate. In our experience the sweep speed has varied as little as 10% and as much as 30% on one of the instruments. This, of course, would make your values falsely high, and I see that although you say they correlate to some extent with the ones reported
