Developments for recording lumbosacral evoked potentials.
Detailed measurement of lumbosacral evoked potentials is usually only feasible using sophisticated, multichannel neurophysiological equipment. This paper describes the recording technique, and the additional equipment developed for use with a high-quality two-channel recording system, the Dantec Neuromatic 2000M, to facilitate the routine measurement of these potentials. The characteristic feature is a microprocessor based control unit, which allows switching of multiple input channels prior to preamplification and detects the electrocardiogram to trigger the stimulus with a variable time delay.
