  1. Sources of variance in exposure to postural load on the back in occupational groups.

    Article - En anglais

    The variability of exposure to postural load on the back was studied in five occupational groups.

    A random sample of workers in each group was observed for two periods of 30 min during a shift, their posture being classified every 20 s. The estimated percentage of time spent in trunk flexion and rotation formed the principal measures of exposure.

    The partitioning of the total variability of exposure showed that occupational group status was the principal source or variance.

    The between-group variance accounted for 47 and 72% of the total variability of exposure to trunk flexion and rotation, respectively.
