Reappraisal of Supraorbital Sensory Nerve Conduction Recordings: Orthodromic and Antidromic Techniques.
OBJECTIVE To establish a supraorbital nerve sensory conduction recording method and assess its usefulness. METHODS Thirty-one healthy subjects without a history of trauma or neurological disease were recruited. For the orthodromic procedure, the recording electrode was attached immediately superior to the supraorbital notch. The stimulation electrode was placed on points along the hairline wh...
متن کاملDouble-Peak Response in Orthodromic Sensory Nerve Conduction of the Median Nerve
OBJECTIVE To understand the neural generator of double-peak potentials and the change of latency and amplitude of double peaks with aging. METHOD In 50 healthy subjects made up of groups of 10 people per decade from the age of 20 to 60, orthodromic sensory nerve conduction studies were performed on the median nerves using submaximal stimulation. Various stimulus durations and interstimulation...
متن کاملAmplitudes of sural and radial sensory nerve action potentials in orthodromic and antidromic studies in children.
Several previous studies of adults have reported that the amplitudes of the sural and superficial radial nerve action potentials (SN and SRN SNAP respectively) are larger with antidromic than with orthodromic recordings. However, this difference has not been documented in children. This study evaluated the amplitudes of SN and SRN SNAPs obtained with antidromic and orthodromic recordings in chi...
متن کاملAntidromic Sensory Conduction
Sears (1959) stimulated the median nerve at the wrist and recorded the antidromically evoked sensory potential from the fingers. Since a larger response is usually obtained with antidromic conduction (Buchthal and Rosenfalck, 1966), and as its latency has been believed to be identical with that of orthodromic conduction (Campbell, 1962; Ruskin and Rogoff, 1964; Goodgold and Eberstein, 1972), th...
متن کاملStudies of sensory conductions. Comparison of latencies of orthodromic and antidromic sensory potentials.
Latencies of orthodromic and antidromic sensory potentials were compared in 16 normal median nerves. Peak latency was longer in the antidromic sensory response in every case. The peak latency of the antidromic sensory response depended on the distance between the recording electrodes; with shorter interelectrode distances it was similar to that of orthodromic sensory response.
