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, 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. The residual latency index (RLI) is determined by dividing the short segment residual latency (palm-digit segment) by the residual latency for the entire terminal nerve segment (wrist-digit segment). In the carpal tunnel syndrome (CTS) infact, as the sensory nerve nerve conduction velocity approaches the wrist, it slows perceptively. Residual latency measure the time latency produced by that slowing (wrist-digit segment), and by adding a midpalmar stimulation site, the contribution of the palm-digit segment to the RL can be studied.
