A study was made of the work posture of telephone operators using video display terminals. The posture was incorrect for all spinal segments due to the fact that the seated position had to be maintained for long periods with the arms raised and unsupported. The frequency of cervical, thoracic and lumbo-sacral alterations of the spine in the whole group of telephone operators was also studied by means of a special questionnaire. An appropriate clinical-diagnostic protocol was used in a suitably selected sample group. The clinical results obtained, stratified into age classes and by sex, were compared with the data already available for a group of sex- and age-matched subjects, not exposed to occupational posture risk. The telephone operators studied showed a greater and significant tendency to contract chronic degenerative alterations of the cervical, thoracic and lumbo-sacral regions of the spine, compared to controls. These results support the hypothesis that prolonged seated work postures constitute a risk factor for the spine.
