In Reply.—  The study by Kaplan et al was published in September 1977, while our manuscript was submitted for publication in July 1977. Furthermore, the author simply stated that axillary, musculocutaneous, and suprascapular nerve latencies in the affected limbs were normal in their patients. They did not furnish the actual values and did not compare these latencies with those in the normal limbs. It is possible that their latencies in hemiplegic limbs may not have been "normal" compared with the values in the normal limbs of their patients. In fact, we reported in our study that in three patients (No. 2, 6, and 10), the brachial plexus latencies in the hemiplegic arms were prolonged as compared with those in the unaffected arms, although both the values were within the accepted normal range.Whether the abnormal latencies in our patients could be compatible with decreased skin temperature in the hemiplegic side is
