has part has part characteristic of has modifier peripheral nervous system neuron transmission of nerve impulse Decreased nerve conduction velocity Nerve conduction velocity is usually measured with surface electrodes placed on the skin over nerves at various locations. Following stimulation at one electrode, the speed at which the signal is propagated to other electrodes is recorded. Abnormal values may suggest demyelination, a conduction block, or axonopathy. Abnormal nerve conduction velocity abnormal decreased rate
