[Occurrence of carpal tunnel syndrome among workers engaged in manual labor].

Examinations of 835 manual workers were performed, as a result of which high prevalence of carpal tunnel syndrome (CTS) was revealed (36.6%). Neurological studies proved a predominant (90.1%) occurrence of the 3rd stage of CTS cases. The analysis performed showed that the right arm was more affected, which was proved by lower sensitivity registered through electroneuromyography. In about 1/3 of the CTS patients, the disease was registered within 3 years of work. In 13.5% cases, the syndrome developed within several months of intensive manual labour.
