Abstract |
Transmission of trains of stimuli were investigated in human sensory and motor median nerves. We studied the effect of prolonged high-frequency stimulation in normal median nerves. Nerves could conduct impulses at 50 Hz for 30 minutes without complete conduction block. However, there was a statistically significant increase in latencies of the compound muscle action potential and sensory action potential. These change were reversible upon cessation of stimulation. |
