Title Variability in the median and ulnar nerve latencies: Implications for diagnosing entrapment
Bibliographic information Nov. 1995, Vol.37, no.11, p.1293-1299. Illus. 21 ref.
Abstract Electrodiagnostic studies were performed on 1472 patients with upper-extremity symptoms. Age and anthropometric measurements were the major determinants of median and ulnar nerve latency variability at the wrist. For patients with work-related complaints, there was only slight correlation between workplace factors and latency. An increased wrist ratio, an increased body mass index and ageing were associated with prolongation of median latencies, and ageing and increased height with prolongation of ulnar latencies. Interpretation of electrodiagnostic studies of the median and ulnar nerves should include consideration of age and anthropometric measures, otherwise entrapment neuropathies such as carpal tunnel syndrome will be overdiagnosed.
