Cervical Spondylosis in Blue Collar and Office Workers: A Comparison of Heavy Manual and Sedentary Workers.

Abstract

The occurrence of cervical spondylosis in a group of blue collar workers was compared with the occurrence of this condition in a group of office workers. The study showed a prevalence rate of 34% in the blue collar workers, significantly higher than the office workers. it is concluded that cervical spondylosis is not exclusively an ageing phenomenon, but heavy manual labour as an occupation plays an aetiologica1 role.
