residual latency (RL) studies

The residual latency (RL) is the calculated time difference between the measured distal latency of a sensory nerve and the expected latency (wrist-hand, 8 cm segment), calculated by dividing the distance between the stimulating cathode and the active recording electrode by the maximum conduction velocity measured in a more proximal segment of the nerve (wrist-elbow segment). For some authors the residual latency techniques, introduced since the 1960s, seemed to be an accurate way of measuring the state of the delicately tapering nerve endings distal to the wrist. In the second half of the 70s was added a palm stimulation in order to determine the short segment (4 cm segment) residual latency, and it was introduced the residual latency index (RLI), determined by dividing the short segment residual latency by the residul latency for the entire terminal nerve segment.
