title: The relationship between long latency responses and height.
abstract: Long latency responses to electrical stimulation of nerve trunks in upper and lower extremities were studied in 83 healthy subjects. The latency differences between the late responses, M2, and the segmental reflexes, M1, on the hand correlated with the height, confirming a transcortical reflex loop. Corresponding to the possible polysynaptic spinal origin of the late reflex response on the lower leg, there was no correlation with height. Therefore, it is not possible to calculate the intraspinal conduction time from long latency reflex examinations.
