Dr Kaplan has raised some important points and the data that he requests is partially available from the original EMG reports. Case 1 had numerous positive sharp waves in both arms and in the paraspinal muscles. Occasional sharp waves were seen in the tibialis anterior and gastrocnemius muscles bilaterally. The motor and sensory nerve conduction velocities and distal latencies were normal in the right median, ulnar and left tibial and peroneal nerves. Case 2 had normal motor and sensory conductions and normal distal latencies in the left median and ulnar nerves. Case 3 had positive sharp waves in the right triceps. The motor and sensory nerve conduction velocities were normal. Case 4 had positive sharp waves in the left quadriceps, with normal motor and sensory nerve conduction velocities and latencies.Unfortunately, no measurement of the F-wave response was performed on any of these four patients preoperatively, although I agree that
