Subclinical carpal tunnel syndrome in hospital staff.

An electrodiagnostic study was performed on 50 subjects (one hundred hands) of asymptomatic hospital staff (pharmacists, secretaries, typists, nurses, cleaners, and cooks) by using an MS-92 electrodiagnostic instrument at Ramathibodi Hospital, Bangkok, Thailand. It was found to be 64 per cent. The longer the duration of the worker's experience on the job, the greater the incidence of carpal tunnel syndrome. Based on the result of this paper: cleaners, pharmacists and nurses face a higher risk of developing carpal tunnel syndrome 5.67, 3.92 and 2.24 times greater, respectively, than others.
