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.

Herpes simplex viruses (HSV1 and HSV2) establish latency in peripheral ganglia after ocular or genital infection, and can reactivate to produce different patterns and frequencies of recurrent disease. Previous studies showed that nerve growth factor (NGF) maintains HSV1 latency in embryonic sympathetic and sensory neurons. However, adult sensory neurons are no longer dependent on NGF for surviv...

OBJECTIVE To analyze differences in carpal tunnel syndrome (CTS) prevalence using a combination of electrodiagnostic studies (EDSs) and symptoms using EDS criteria varied across a range of cutpoints and compared with symptoms in both ≥1 and ≥2 median nerve-served digits. DESIGN Pooled data from 5 prospective cohorts. SETTING Hand-intensive industrial settings, including manufacturing, assem...

OBJECTIVE To establish nerve conduction parameters for carpal tunnel syndrome (CTS) electrodiagnosis in the elderly. METHOD Thirty healthy subjects (65-86 years), 9 male and 21 female, were studied. Routine median and ulnar sensory and motor nerve conduction studies, median mixed palmar latency, comparative latency techniques median to ulnar (sensory, mixed and motor lumbrical-interossei), me...

objective: diabetes mellitus is one of the most common endocrine diseases with micro-vascular complications and is a common cause of polyneuropathy. we studied the effect of enalapril on electrophysiologic criteria and clinical symptoms of patients with type ii diabetes and sensory neuropathy. materials and methods: a double blind study was conducted on 45 patients with type ii diabetes and neu...

OBJECTIVES Traditionally, nerve conduction study (NCS) are used to diagnose carpal tunnel syndrome (CTS). However, no NCS has the sufficient sensitivity or specificity values to diagnose CTS by itself. Median terminal latency index (mTLI) and median residual latency (mRL) are parameters that calculated to identify abnormalities in distal segments of the median motor nerve. There are few studies...

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...
