The angular ranges of the movements of the head and trunk (flexion, extension, lateral bending, rotation) were studied in two male groups not suffering from diseases of the cervical spine (Group A: No. 167) and thoracic and lumbosacral spine (Group B: No. 155). Each group was stratified into 4 age sub-groups (16-25; 26-35; 36-45; 46-55 years). In addition, the angles of thoracic kyphosis and lumbar lordosis were studied in Group B. The data collected in the study were processed in order to estimate, for each sub-group, the reference values of the different parameters that were examined. In addition to the 95% confidence limits of the mean values, the values corresponding to the 5° percentile of the sample distribution were computed by means of tolerance limits. On the basis of these values, using a conventional criterion, new data collected are judged as 'reduced' or 'normal'. The availability of such reference values is of an advantage in improving the diagnostic criteria of the clinical method for screening spinal disease proposed by the Authors elsewhere.
