[Structure of antero-posterior spinal curvatures in manual workers in relation to their occupations].

The authors examined spondylometrically 1572 (648 men and 924 women) labourers of the FAEL factory in Zabkowice Slaskie. Sixteen spondylometric features were taken into account. The results were analysed by generally adopted statistical methods. Calculations were made for men and women separately. The subjects were divided into those performing their work in sitting and standing positions. Furthermore, the workplace of each worker was examined. The studies demonstrated a considerable correlation between the antero-posterior curvatures of the spine and specific workplaces.
