The present study was undertaken with the aim of developing a method for determining radial nerve sensory responses which would be technically simple to perform, relatively painless, and give reliable recordings of sufficiently high amplitude to avoid the need for an electronic averager. Materials and methodsA TECA TE4 electromyograph (White Plains, New York) was used to elicit and record responses on photosensitive paper for measurement. The high frequency filter setting was 3 2 KHz; the low frequency filter setting, 32 Hz.
