Distal sensory latency measurement of the superficial radial nerve in normal adult subjects.


The antidromic distal sensory latency of the superficial radial nerve was studied using 2 methods: (I) Recording from a major branch of a nerve as it crosses the extensor pollicis longus tendon, using segments of 10, 12, and 14cm; (II) Recording from the thumb, using segments of 14, 16, and 18cm. The mean latency, to the peak of the negative response, using… (More)
