  1. The relationship between low back discomfort ratings and the NIOSH lifting index.

    Article - En anglais

    An epidemiological study was performed to evaluate the relation between low-back discomfort ratings and use of the revised NIOSH lifting guide to assess the risk of manual material handling (MMH) tasks.

    We surveyed 97 MMH workers on site in 15 factories and designed a questionnaire to systematically collect job-related information.

    Approximately 90% of the workers had suffered various degrees of lower back discomfort, and 80% had sought medical treatment.

    The survey showed that 42 of the 97 jobs analyzed had a recommended weight limit of 0, which was attributed to either a horizontal distance or a lifting frequency that exceeded the bounds of the NIOSH lifting index.

    Apparently, the limits for horizontal distance and maximum allowable frequency are too stringent to accommodate many existing MMH jobs.

    For the remaining 55 jobs, the significant positive correlation obtained between the lifting index and the severity of low-back discomfort suggests that the lifting index is reliable in assessing the potential risk of low-back injury in MMH.

    These findings provide useful information on the application of the NIOSH lifting guide to the assessment of low-back pain.
